the key here is to watch them VERY carefully when you're dragging em up. i fell for that "fake" stall in the past. then i started being a bit late in nosing over for a stalled con.
 what i do now, is to watch for the nose to "wobble" a bit, then wings dropping.....these are kinda hard to fake, and a sure sign that he's about to stop flying for a few seconds. When i see the combination, i crank her over, and take my shot......although i generally miss, as my gunnery sucks.  :D

If you don't already do it, you should try cutting throttle as soon as you nose over. It'll give you longer to line up a shot.

i do....since i'm almost always one of the 38's, i crank hard rudder, and aielron, as i chop throttles to idle......then i adjust as needed when i'm pointed the right way.

thanks!

No, trust me. This was nobody special. Typical ho-an-yank pilot in the spitty. Very low on the skill chart. And no it wasn't a "fake dip" because he had to completely roll under himself to recover.

Spits are just UFOs in this game.

Then it should be easy for you to fim yourself doing so as evidence and get HTC to change it.

Or your full of roadkill as usuall when it comes to Spitfires.

Why is it that the P51 is so much faster than the Spit 16, but the Spit 16 holds E better and is so much better in the vertical? If the P51 is so much more aerodynamically "cleaner" than the Spit, then shouldn't it hold E as well? If the Spit is better in the vertical because it is lighter, shouldn't it also have a higher top speed (power to weight)?

Well of course it's for the same reason the Spitfire LF Mk IX  (AH Spitfire 16) has a higher maximum rate of climb than the P-51D in real life even though the P-51D has a higher top level speed.

Once you find the answer to this question then you'll also find the answer to your original question ;).  Sorry, I don't have time to post anymore at the moment.  Work through the dynamics involved above and you'll find the answer you're looking for.

No, trust me.
See.. that just doesn't cut it when it comes to the FM. I'm quite sure HTC spends a great deal of time on that.  Do you think If I said " Trust me, the 190 could do 700 mph on the deck." is all that is needed?

The full question is "needed for what". Anecdotic is enough to point out that something's wrong if it's that obvious (e.g. the tempest being unhistoricaly faster in level acceleration), but not to say what the fix is. HTC coded the thing and prolly dug thru all the documentation, so they prolly know all about it and more than anyone else... just sayin.

note the power to mass ratings. that's why(at least partly) the spit can climb, and accelerate faster, turn tighter, and do seemingly impossible things.

I was in a Ta152, had speed and alt at about 8-10k. A spixteen zooms up from below me with a bit of speed so I spiral climb up. It takes him a while to stall out, but when he does (at 600 yards) he stalls hard enough to dip a wing. I was saving my E for this, so I'm about to roll in on him and he recovers.


Just so I learn, how do you save your E while spiral climbing?

Don't confuse Energy Retention with low Induced Drag.

Imprecise terminology.  Induced drag increases with angle of attack, not lower speed.  While typically, AoA increases as speed decreases, you'll get lost in the terminology if you approach this comparison from these perspectives.

Saving Energy is when you're flying along and you see a bogie below you and you keep stalking him until you're ready to pounce, which at that time you're cashing in the Energy you were saving while stalking. 

What Krusty was describing isn't saving energy by using a spiral climb, he was doing what you said, gaining potential energy.

    Quite understated actually.  What I was trying to point out, diplomatically, was that you cannot answer the OP's question by comparing induced drag.  The difference in the induced drag of either plane is not the property that differentiates the two aircraft with respect to the original question.

    i still think it's got more to do to their weights, and power to weight ratios than anything........[/list]
