Title: P-47 Guide
Post by: fyvsix on August 31, 2008, 10:24:50 PM
I wrote this a few weeks ago for my squad. If it's any value to you folks then great, if not feel free to poke fun. ;)

Putting the “Thunder” in the Thunderbolt

My Aces High name is Fyvsix, I chose that moniker for one reason. The 56th Fighter Groups was in my opinion the greatest group in the ETO. They pioneered tactics and equipment to put the P-47 into combat in a war winning way. The Thunderbolt has always been my favorite fighter, the P-38 is a great and graceful fighter, the Mustang is a purebred, built for speed killer, but the Thunderbolt has heart! For me the Thunderbolt is a great example of what Americans value in a fighting machine! It was big, tough as nails, very fast, extremely well armed and very “in your face”. If flown properly it can be a very tough opponent. You can take it up get good kills and get home. If you practice good tactics and have some self control, you can generally come home without a scratch. If you do lose control and get into a dogfight, you can take a beating and still fly home.

I’ve decided to author a little guide to my squad (353rd Fighter Group) to encourage them and help teach them to use the Jug. General Kepner of 8th Fighter command said this about the P-47 and I’m not sure I could do any better: “If it can be said that the P-38 struck the Luftwaffe in it’s vitals and the P-51s are giving it the Coup de Grace, it was the Thunderbolt that broke it’s back.”

47’s in general.

There are some traits that all of the models of the Thunderbolt share. They are all huge and heavy. They all carry 8 .50 Caliber M2s in their wings as a primary armament. They all guzzle gas with those 2000+ horsepower Pratt & Whitney R2800 18 cylinder Wasp radial engines. They are all relatively poor climbers, but being heavy they will hold momentum and zoom well. They are all very durable and soak up a lot of damage. They are all fast and improve in most respects with altitude. At 20,000 feet or above the P-47 is a match for any propeller driven aircraft in speed, and maneuverability.

Know Your Jugs!

There are four different models of the P-47 in Aces high, three “D” models and the “N” model. Sadly there is no “M” as of yet. I’ve linked Soda’s evaluation which can be helpful.

The D11 is your razorback model with limited external ordnance of a 500 pound bomb or a 75 gallon drop tank. This model is the first with the paddle bladed props that help with climbing, acceleration and high altitude performance. The views are not as good as the late models, but when you get used to then, they are no hindrance. The D11 is the most maneuverable of all the 47s, it being the lightest. I fly the D11 more than any of the other models.

The D25 is the first of the “bubbletop” jugs. It’s a little heavier than the D11 and a little less agile, but the difference is hardly noticeable. It is not quite as stable in the Y axis and will yaw at slow speeds. The views are of coarse very good. The D25 has a great many external ordnance options including multiple bombs, rockets and external fuel tanks. A word about the rockets on this model: they are the bazooka type that requires that you keep the launch tubes attached and these hinder performance by a small but noticeable amount, I generally leave them at home. This is the first of the longer range Thunderbolts. It’s good for any mission, be it high alt escort, or ground support.

http://members.shaw.ca/soda_p/P47D25.htm

The D40 is the final development of the D model. It has a little more power and climbs a little better than the previous models. Let me just say, if you are relying on climb to fight in a P-47, then you are doing it wrong. It, like the D25 is a bubbletop but it also has a dorsal fillet attached to the vertical stabilizer to give it less yaw. The D40 will fight in the air like any other Thunderbolt, but it is also idealized for ground attack and can carry 2500lbs of bombs plus rockets. It is a good late model P-47 and was used a lot for ground attack by the 9th air force.

http://members.shaw.ca/soda_p/P47D40.htm

The P-47N is the latest addition to the line of jugs. There are quite a few differences between this model and the earlier ones. The N model carries a lot more internal fuel as it was intended for long range escort in the pacific. The wings were redesigned, fuel tanks added and the engine upgraded. This model is very fast in WEP, it gains near 40 MPH in WEP and can run down all but the fasted enemies while the WEP lasts. Without the WEP however it is more sluggish than the other models. Like the D40 it can carry truckloads of ordnance when needed. It’s very fast at altitude as well. As I am mostly an ETO guy, this model is my least favorite of the 47s.

http://members.shaw.ca/soda_p/P47N.htm

I have one additional note on the missing Jug. (I can’t resist) The 56th Fighter Group deployed around 150 P-47M’s in winter/spring of 1945. These M models had a Double Wasp engine and were the fastest propeller driven planes in theatre. The M model had a top speed of near 475 at altitude and did much to help with climb and acceleration. There is one instance where an M model caught and killed 262 in a shallow dive. I think the M model should be added as a perk.

In the Tower

You can set yourself up for failure or success to a certain extent before you even get off the ground. The important thing is that you plan for the mission at hand.

On my first FSO mission when I flew with the old 56th Fighter Group, It was a long range mission in the 47D25 and I had to ditch in the Med because I ran out of gas. This has instilled in me a mortal fear of running out of gas, If I’m in charge a mission we are taking enough gas to get there fight for a while and have plenty to get home. I hate running short on gas, I’d rather run out of ammo than gas. The P-47 burns gas faster than an Shell station on fire, so I usually take at least one drop tank for climb out and 3/4th tank of internal gas. The 47 tend to take fuel hits in it main tank, so after externals I burn Main and save my Aux tank for getting home. I like to be at altitude over the target with a 3/4th tank of gas.

I generally take the max ammo load of 1700 rounds so I can keep that trigger down just a bit more. This is especially useful when you are strafing, 450 rounds per gun is a lot of firepower. You can get buy with the 1048 round loadout just fine for air to air stuff, but I don’t like to run out, and the weight difference is negligible.

As far as ordnance goes, take what you need for the particular mission. If it’s tank busting in a D40 or N then I take 2x 1000lb eggs under the wings, a 500lb egg on the centerline rack and rockets on the wings. Remember to take enough gas to loiter a bit to give those friendly ground pounders some good support.

Climb Out

Climb speed is defaulted at 160 MPH which is historic for the P-47. This gets you about 2,000 to 2,500 feet per minute at non-WEP full throttle and clean. If you are fully loaded with fuel and bombs it’s going to be about 1000 feet a minute at full throttle.

If I’m climbing out and conserving fuel in my drop tanks I’ll back the throttle down to normal power or so and climb a little slower. It really depends on how far you are going and what amount of room you need to climb. The real guys in Europe used full throttle for take-off, got formed up and climbed slowly at low throttle settings to conserve fuel so they could have more to fight over Germany. If given room, I’ll do it the same way. Just as a general rule, I’ll try and do things the way the real guys did it in almost every case.

I try to climb to very minimum of 10,000 feet before engaging lower or co-alt cons at speed. I prefer 15k or 20k or 25k or 30k much more. I guess what ‘m saying is that you cannot have enough altitude or potential energy if you will. If I’m going in co-alt at a good altitude I want to be at or close to full speed. So level off a little early and build some speed going in.

Cruising

This may not seem very important in some of the arena’s we play in, but it may be the difference between life and death. Fuel is blood up there in the skies, you run out and you don’t live to get home. Here’s the rub, at full throttle you get max speed while using a great amount of gas. On the other hand if you are running with the throttle back a bit you can keep good speed and save a lot of gas in the process. Cruise speed is around 180-200 at max fuel conservation, you can still save a lot of fuel while running around 225-250 indicated. You can run full about somewhere around 300 indicated and blow a full tank of gas in 30 minutes. Sometimes you don’t need the gas, sometime you really need to conserve. I always try to come home and like the real guys I worry a great amount over fuel. Cruising is also subject to the mission at hand. A good high speed general setting that will conserve some gas is 40 manifold and 22 RPM’s.

Speed & Turning

Speed is life, this is never so true as when you are in the cockpit of a Thunderbolt. Low and slow gets you pretty defenseless, pretty fast. Contrary to popular opining the 47 turns very well at high speeds (225+) and will not compress until well over 500. One thing that really shines and puts the jug in the top few plane in the game is the roll rate. It’s very quick at speed and can be used to change attitude very fast. One rule of thumb is the faster you and your enemy goes, the more advantages you have over him. There are a few exceptions in general, but none in a dive.

Don’t be too timid and afraid to try and make a few turns in a high speed fight, you will dump you speed fast, but with 8 .50’s you don’t need to get guns on them for long and they are in pieces. I try not to stay in the fight under 200 miles an hour so I do not get caught in a disadvantageous position.

More speed = More advantages for the Thunderbolt!

Fighting Tactics

There are three basic modes of Thunderbolt combat and multitudes of variations and combination of the three. The three basics are Boom and Zoom, Slashing and to a lesser extent Turning. The main idea is to get guns on them without letting them return the favor on you. In the P-47 the best way to do this is to use your energy advantage (You did get one before engaging didn’t you?) and your superior firepower to destroy the enemy. This is the way the great groups in WW2 killed the Luftwaffe on many occasions.

Boom and Zoom is the quintessential jug tactic, come in high dive down on the bad guy’s tail (unbeknownst if possible) hammer them with your 8 guns and use your momentum to zoom back above the fight, leaving yourself with enough vertical and horizontal separation to not get fire upon. I use BnZ most of the time I am engaging a single target one to one. The classic attach profile is to dive to the bogey’s altitude about 1-1.5k back and close really fast opening up in range and then turning slightly and zooming back up after firing. Id the enemy is dead the zoom can be in any direction, but if you miss or he breaks, you want to zoom away for maximum separation from his flight direction.

For multiple target I use a slightly different method to engage. As you may have guessed this one also begins with me having a good speed and/or altitude advantage. (notice the theme here?) This is a great place for the slashing type of attack. The way this works is pretty simple. The goal is to get some shots in without giving up your speed and safe exit. You start out like a BnZ and build speed diving to the attack of your selected target. You make a pass on him and hit or miss you move on to another target in your general flight path. I will make small turns to get lead on these passes, but I try to really keep my speed up so as not to get vulnerable. Low and slow = Dead and Dead. So I’ll blow through the group and if I’m in good shape E wise zoom out and extend for another run. If’s a little slow from too much turning, I’ll dive to pick up air speed and extend that way. Sometimes, depending on the opponent I’ll stay in and go for the kill a little harder, but that is a decision you can only really make with some experience.

Again, you don’t need a lot of time on target in order to destroy them. You are throwing over 100 rounds of .50 cal for every second of fire. That is almost an unrivaled concentration of firepower. If you are making a pass and it is ends up being a head on, then I generally consider that the enemies mistake and give them a nice burst in the teeth. If you are on target you should hear them detonate as you pass over or under them. I generally try not to HO the machines with four or more cannon however.

The third mode of fighting is either out of desperation because you’ve made a mistake or because you are fighting an equal or lesser maneuverable machine. This is the dreaded turn fight. The Jug can do ok, but not for an extended period of time. Mostly this happens after a fight or at the tail end of one that you’ve stayed engaged for too long. Sometimes you just can’t help it and are stuck fighting it out low and slow. There are some tips that I can give that will help increase your survival, but can’t really be relied upon if you are facing a good stick. The first thing I do is to turn in to whoever is making a pass at me if I can, about half will break and half will HO. The smart ones break realizing you used a lot of E to turn into them. The ones that HO often get hammered with your guns and learn not to do that gain. You can use flaps a few notches to help bring it around, but don’t leave them out as it will kill your speed even more. The other trick I can offer is the E-Dump forcing an overshoot. This is a truly desperate move because it leaves you totally vulnerable, but in this situation it may save your life. Dump your flaps throttle all the way back and break, be careful not to stall in the break and you will slow down like your wearing a parachute. If the bad guy is a veteran he will go vertical and come back to kill you, if not he will over shoot and possibly give you a snap shot. Again the jug is a death start with wings with those 8 .50’s, so you know the rest. The Jug can fly very slow and not stall, so some inexperienced pilots may auger. I will usually try to extend before resulting to these defensive measures.

Shooting

All the maneuvering and planning are for nothing if you don’t do some shooting and put lead on target! Fortunately the Thunderbolt lives up to it’s name and has a lot of lead to go around. I don’t think it’s an underestimate when I say that the P-47 has one of the most powerful gun packages in Aces High. As I said before you don’t need a lot of time on target to make the bad guys go boom. It took me about six months until I started to shoot better and get kills and I still have nights where I can’t hit anything. (too many nights) So what I’m saying is keep practicing your aim and don’t get discouraged.

Truth be told the Jug is probably not a good one to learn accurate shooting and ammo conservation on. When I fly the P-51B (Probably my second favorite ride) I must be very careful not to run out of ammo, it has half the guns and a lot less ammo than the P-47.

With the jug you are much more prone to fire streams of ammo downrange try to get hits and kills. This is a fine way to fight, I do it all the time. Lead the enemy enough that he flies right through your stream of .50 calibers and he will likely go down and hard. If these guns will take out a locomotive then the will destroy anything that can fly. I will pull what I think is good lead and sometimes adjust it mid-stream to get on target, just like pissing on a bug when your camping. Just don’t lead too long and keep trying to turn to stay on target losing all your E. Don’t be afraid to us up a lot of ammo to get that kill at a high deflection angle or pass, you should have plenty to go around.

A word about the gun loadouts may be in order here as well. The six gun package may appeal to you in a weak moment, but don’t be tempted! The jug is not an extended turn fighter and you are never going to save enough weight to make it one. If you take all the guns and fuel out it still weighs something near 12,000 pounds which is twice what a spit weighs. It will surprise you sometimes, but generally you are relying more on power then maneuver. The same can be said of the ammo loadout for the eight gun package. Take the maximum and do not put yourself in a position where the extra weight will be a hindrance. Besides, if you are doing it right, your ammo supply will trim itself down soon enough

Convergence is another area of confusion for folks. I keep my outer guns at 400 and my inners at 425 to get a good group in the killing zone and still be able to make some long range shots. I learned this from Bluekitty from the old 56th She is one of the best jug pilots ever to play Aces High, so I never really looked back. It is my feeling that fast planes like the Thunderbolt and Mustang do well with a 400ish setting and slower planes that fight more up close like the P-40 do well at about 300 convergence. It’s really a personal preference as to what you can hit and kill with. I read one account of a pilot in the 325th Fighter Group setting his eight .50’s at 100 yards so he would not miss.

Good deflection shooting takes practice, practice and more practice. There is no shame in practicing offline either.

Ground Attack

Ground attack is an important mission for the P-47 that was increasingly flown as the war progressed. The D25, D40 and N model excel at this role. A flight of four P-47’s can carry more ords than a B-17 or B-24. It’s pretty easy for them to knock out airfields, Ground bases or towns. The heavy bombs can take down the hangers and hard targets and the rockets and 3400 rounds of .50 cals can work over the soft targets in a real hurry. On one mission the 56th Fighter Group expended 78,000 rounds of .50 caliber ammunition strafing an airfield in Germany.

For hitting targets with bombs I usually dive bomb. A good altitude to start at is about 7,000 feet. I come over the target, roll over and dive in at a 15 degree or less angle. Let the stick center and settle down making sure that your pipper is centered on the target in as much of a hands free attitude as possible. Release those bombs around 2,000-4,000 feet leaving plenty of time to pull out. I usually salvo both my wing mounted bombs at once, mainly because that is the way the real guys did it.

Strafing is something that the jug naturally excels at. High speed and heavy firepower as well as the ability to take some hits make it a ground attack fighter-bomber almost without equal. I like to come in fast and relatively shallow angle of 30 degrees or less. The faster you come in the less chance the AA has to get you. The accounts I’ve seen put it about 400 to 450 MPH. I have a mortal fear of AA guns and don’t want to hang around getting hit a long way from home if I can help it. De-acking is a much easier job if you stay fast and do it in a group.

Getting Home

This is one of the most important parts of getting that immersion that makes this game so great. I always plan on coming home and do my damndest to make it happen. A lot of times I will throttle way back to get home because of fuel constraints. Make sure you disengage with enough fuel to get home, and perhaps with a little extra reserve in case you get into trouble on the way home. It’s no good killing the bad guys if you don’t live to tell about it. Your AUX fuel tank is a great reserve if you save it will give you a good bit of fuel to get home on.

Situations to avoid

There are some times that you get caught and killed and can’t do a whole lot about it. The best thing to do is avoid these situations. Don’t get caught at a lower altitude than a good energy fighter as you will be left with few options to fight or run. I dread a high P-51 or P-38. Better to dive away and live then engage on the enemies terms.

This may seem obvious, but don’t go chasing enemies through their own flak, no kill is worth the risk and even if you do get your man, you probably will sustain enough damage to knock you out of the fight.

Don’t get drawn in to the enemies style of fight, set up the fight to suit your strong points and don’t engage at a disadvantage. At time this takes more self control than I have, but I usually pay for the mistake when I’m low, slow and potentially dead.

Well, I’m a bit typed out for now, I hope this will help some of you guys who are new to the jug and as always I’m open to suggestions and advice. One last note: these tactics while optimized for the Thunderbolt will work very well for any number of fighters including the P-51 and P-38, they just don’t quite have the balls the 47 does. ;)

PS, I’d kill for a good 353rd Thunder bolt skin.

The D11 is your razorback model with limited external ordnance of a 500 pound bomb or a 75 gallon drop tank. This model is the first with the paddle bladed props that help with climbing, acceleration and high altitude performance. The views are not as good as the late models, but when you get used to then, they are no hindrance. The D11 is the most maneuverable of all the 47s, it being the lightest. I fly the D11 more than any of the other models.

Everything I've read indicates that the D11 is the one model in AH2 without the famed paddle props.  That aside, your posts were a great read, thanks!

Personally, I like to arrive over the target with 50% in any Jug.  Depending on the model you use, this can result in a different configuration for all of them at takeoff.  Remember that the parasitic drag of the drop tanks is greater than the induced drag of the extra internal weight, so, for the same gallons, I'll fill the internal tanks before taking drops.  This means, in the D11 for example, I'd rather have 100% internal at takeoff than 75% and the drop tank.

Also, if you want to conform with history, take the lighter 8-gun ammo load.  The max ammo load was rarely used in the war from what I've read, and will make a noticeable difference in performance.  For example, it costs you about 2" of manifold pressure, in that a plane with the lighter load can climb as fast at 50" as a plane with the heavy load at 52".  Roll rate is also better, and overall, it saves you almost 500 lbs which, IMO, makes the plane a bit more maneuverable.  Furthermore, unless you're doing some heavy bomber banging, the lighter package is still enough to take out 6-8 aircraft in one sortie, with proper marksmanship.  Even when I take 100% internal fuel, I still run out of gas before I run out of ammo, even with the lighter load.  The only exception is when I'm specifically launching to take on bombers.  Most of the time I still take the lighter load, but sometimes I'll take the heavier.  I have landed 6 B-17/B-24 kills with simply the light ammo load.

Second, climb on full power always.  You don't save any fuel by climbing on reduced power--matter of fact, you'll burn more gas doing that.  I use WEP for climb out after takeoff in all of the P-47 models, at least until I hit the redline on the oil temperature gauge.  It may be non-historic, but the engine management in AH2 does not even attempt to replicate that which you would find in the cockpit of any of the aircraft in-game, so, when in Rome, do as the Romans do.

Third, maximize the capability of the planes when they're at 25% fuel.  A P-47N at 25% and half of the light ammo load begins to approach wing-loading levels of much smaller aircraft, and performance overall approaches that which is almost "Spit-like" :).  Seriously though, all the P-47's become much more capable at lighter weights--I don't think there's another aircraft that is affected by its gross more than the Jug.  Learn how to sip fuel at 1700 RPM and 30" of MP and you can cover 2-3 sectors on an 1/8th to a 1/4 tank of fuel, depending on model.  That will really maximize your effectiveness over the objective with longer loiter and much greater maneuverability.

Last, you can reach compression speed in a dive from as low as 7-8,000 feet, so that's your minimum safe escape altitude.  If you have that much altitude, you can get away from almost anything if you so desire.

I don't fly a P47, that said;

I'm not sure why you would drain the aux tank first, it is behind the Center of Gravity and would likely increase the risk of spins. Doing so in 'case you get hit' seems a bit silly to me, almost akin to me flying my P38 with only one engine, in case one gets damaged.

I don't know about you, but I'd like to have whatever I'm flying as fight ready as I can make it.

Thanks for all the kind words and good input. As always Stoney's comments are gospel, Perhaps I make a few revisions.

It took about 6 hours to put together to answer one question.

For MjTalon, feel free to use this as a reference as long as you give me credit when you do.

Boiler, I read somewhere that it was modeled with a Paddle blade, maybe I'm wrong though.

Delirium & Tony, I meant that you drain the main and save a bit of aux becuase it seems like you get hit in the main a lot.

I think Delirium mis-stated his post.  Given the context of the rest, I think he meant to say "I'm not sure why you would drain the Main first".  I'm personally not sure that the Aux tank on the Jug makes that much difference.  Given that the Main tank on a Jug is forward of the cockpit, and the Aux tank is underneath the cockpit, the stations, relative to the position in the Jug versus most planes, don't look like they're in positions that would create a huge difference.  I'll caveat that by saying that I've never seen a P-47 Weight and Balance sheet to know what the CG envelope is, nor where the actual CG is for our in-game planes at each fuel loading condition.

Delirium alludes to the fact that in most in-game aircraft, the Aux tank is located further aft, and therefore decreases spin recovery when full; i.e. drain the Aux to make the plane more stable.  A good example is the P-51, which, IMO, shows the most conspicuous effect of a more aft-loaded condition.  I have not noticed as large an effect in the Jug, in-game.

As flattering as that statement is, I still make mistakes.  Widewing, on the other hand, can be considered gospel regarding the Jug :)

The best example of how the D-11 does not have the paddle blade prop is in comparison to the D25 which does.  Notice that the D-25 climbs much better than the D-11, even though it is heavier.

I think Delirium mis-stated his post.  

Yes, I did.

That is what I get for reading the forums at work and actually trying to get stuff done. :)

The P47's main tanks are beneath the pilot and in front of the cockpit, well ahead of the CoG.

The Aux tanks are definitely at or behind the CoG, I'm not sure why would ever want to carry fuel there unless you had to.

And the fuel hit is ALways on the main, aux only provides 10 min flying time, its weight has to be negligible

Yes, I did.

That is what I get for reading the forums at work and actually trying to get stuff done. :)

The P47's main tanks are beneath the pilot and in front of the cockpit, well ahead of the CoG.

The Aux tanks are definitely at or behind the CoG, I'm not sure why would ever want to carry fuel there unless you had to.

I'm not so sure about their positions relative to the CG.  The Main is placed right behind the leading edge of the wing in front of the panel area of the cockpit.  The Aux is under the seat area of the cockpit, just forward of the trailing edge of the wing.  This puts all of the fuel within a fairly narrow (109 inch ~ 9 foot) station envelope that also includes the pilot and everything in the wings (including landing gear and weapons).  So, again, without having seen a CG diagram for the Jug, I'd say that's a fairly narrow area compared to some planes.  The CG isn't necessarily right on the 1/4 chord point of the wing, but even if it is, the Aux tank would have a fairly small moment even when full.

I'm not sure why you would drain the aux tank first, it is behind the Center of Gravity and would likely increase the risk of spins. Doing so in 'case you get hit' seems a bit silly to me, almost akin to me flying my P38 with only one engine, in case one gets damaged.

Wait I always thought a tail heavy plane spins easiest. Did I read this wrong or do I need to check my meds?

EDIT: Should have read all the way through the posts first... sorry.

Forgive me if my info is wrong.....  But, I was told to use the main tank first and use the aux tank last because the aux tank is deeper inside the plane and less likely to get hit in a fight... :salute

Well, personally, the Jug's susceptibility to main fuel tank hits typically results from low 6 shots in my experience.  In that respect, the Aux tank should be the first one hit, as bullets would practically have to travel through the entire length of the fuselage and through the cockpit to hit the main.  That said, I have no idea how AH selects the damaged components that are placed in the fuselage.  Also, I don't know if anyone could collect reliable data that shows that the Main gets hit more than the Aux.

One thing good thing about the P-47N is that you also have the option to leave a little gas in the wing tanks if you take 100% internal fuel.  At 75%, there's really not enough gas in the wing tanks to give any credible additional fuel.  Of course, loading all the fuel in the wing tanks seems to affect the roll rate.  Personally, I typically load 75% with no drop tanks on P-47N sorties.  If I'm trying to "furball" it or use it for attack sorties, I typically only load 50%

I too have noticed that the main tank gets holed fairly easily in the Jug, and if its the only thing with gas left in it, your day is over early.  So I agree to save the Aux fuel for backup in case this happens.  Unfortunately in order to have more than a splash of fuel in the Aux, at least in the D model, you have to be at full fuel... and a lot of the time that's undesirable due to the extra weight.
Title: Re: P-47 Guide
Post by: Stoney on September 03, 2008, 10:39:09 AM
My typical fuel loads:

D11  100% (almost always, regardless of mission type)
D25  75%
D40  75%
N     75%

If the fight is a little farther away, I'll bump the D25/D40 up to 100% internal.  Let's face it, unless you use WEP after takeoff, the Jug won't climb worth a darn anyway, so don't worry about takeoff weight.  Concentrate on being at "combat" weight once you're over the target.

Just a note on fuel: I never let my aux drop below 50%, because chances are, ONE tank is going to get hit. So, if the main gets hit, the 50% on AUX will get you home. if the AUX gets hit you should have enough left on main to get home.

A talk page is a space for editors to discuss improvements to articles and other pages.

Not really what the talk pages are for, but if you had a list of FAQ's and answers about a plane it could be edited into the appropriate page, or maybe even warrent its own new page if the content is broad enough.

There's also nothing sacrosanct about the "Flying the [plane] in AHII" sections of the aircraft pages.  Soda's evaluations were intended as a starting point for others to edit/add to.  Soda himself said he would be very interested to see what changes the community might make to his write-ups when he agreed to contribute his evaluations.

just remember this is a sim, not the 'real world'.  in the RW you could find just about any configuration of Jug as Republic produced 'kits' for use in the field to bring older AC closer to current marks.

probably what AH has done is use the 'factory' definition of a type for the game.

in the field toothpick props were replaced with paddle blades as they became available.

Clarification: I like to carry 50% and one or two drop tanks in case I engage enemies on the way to a main target planned. Am I mistaken when I believe dropping ord and 25-50% of my fuel will help in an unexpected fight en-route to increase maneuverability and lighten the aircraft for tighter turns? Earlier you eluded that internal fuel vs drop tanks was a better idea/had negligible effect...?    :headscratch:

Well, typically, if I'm upping a jug, I'm pretty deliberate about setting up the takeoff field so as to not encounter any enemies until I'm at my desired altitude.  This will mean you have to fly a little farther sometimes.  However, your technique is perfectly logical in that you configure the aircraft to strip down to fighting weight instantly should an enemy appear.  Personally, I like taking the internal fuel and flying from a more distant takeoff field.  I don't like fighting the jug uphill in any circumstance (be it light or heavy), and I will exert some effort to prevent that.  That being said, it seems you have a workable technique for yourself--the ability to shrug off the extra fuel or ordnance will make the plane fight much better.

With respect to external fuel tanks versus internal, when I'm cruising to the fight, I like the plane to be clean.  I fight the Jug heavy, using altitude, and  having the plane free of any extra drag will optimize my cruise speed into the fight.  The Jug doesn't accelerate very well, and it can take the Jug a few minutes to accelerate and recover that 15-20 mph that the wing tanks steal.  But again, we're probably talking more in terms of personal preference rather than configurations that will either win or lose the fight for you.

Makes perfect sense. I have often been too low in the jug when I arrived at a fight. Even when the fight previously was near ground level, upon return there's always one or two high 38's or Ponies. I appreciate this thread. Lots of good info and angles to think thru, & as you pointed out we all find what works best for our tactics and when you read something new, you may not use it all, but there is almost always a piece or two you can add to your expanding abilities.  :joystick:

tactially, I like arriving in a hot zone at 18K+ and down to about 50-75% internal fuel.

if there is a friendly field only 1 or 2 grids away that will give me 2-3K 'free' altitude, I will launch from there.
if I have a long way to go, I will change the climbspeed to 200.  that cuts mins off travel time and maintains a 2K+ climb rate.

I use field dar and sky scans to keep from being the 'swoopee' ;)

I read all of this carefully and have gained some good ground. I routinely outrun folks on my 6, and have a much higher kill rate while dive-bombing. At about 7,500ft I invert, flip head switch down and fly 3-4 seconds to line up on target, then pull the stick back, line up on target, drop salvo 2, delay .25 complete a split "S" and watch the kill light up. My only regret is I can't see the bombs hit from outside. I hear other GV's on the ground Hooting and hollering about the "direct hits!"  I get a little cheap thrill, but I would like to see it myself.

I used to direct "red" aircraft from VMFT-401 (F-5s) when I was at 29 Palms.  They'd always request a pass over my position because they knew I'd key the handset as they flew over.  Jet jocks just can't get enough of hearing their own noise...  :)
