Spit Anti Gravity Device

If Wotans not on....give me a yell if I am.  Will change sides

to help you test.

Need to find a detailed version of the test first, with what settings were used in the various tests.  I think I've seen a link to one on here before, just have to find it.

Storch. Simple test you can run.

Take a spit, Fly it level to a preset speed say 300.

Check your begining alt. Pull the spit straight up. When it falls off look at your alt.

Now repeat the above in a plane you like to fly. Starting at the same alt and speed.

Then ask your self, are the results fairly consistant. I.E. one plane may have and advantage in a zoom, but is it drasticly i.e. antigravity different?

HiTech

I'll try that.

Urchin if you want I'll do the side to side test with you

[Urchin]

I'm available now, if the arena is back up.

Storch heres another test for ya. Up a spit V climb to 10K go level with yuor speed up then pull back right with full rudder let me know if you recovered before the ground came up to smack ya

Gee.. I wish I could get THIS much attention from you HTC guys with MY bug in AH2.......................... ............................. .............................

Urchin by trying it online with 2 planes at once you  are already puting varience in the test.  As planes slow down they will move in releation to each other do to net lag.

Much better to try offline with a stop watch, and write down the info.

I'm not going for exact measurements, more like comparisons between actual flight testing and flight testing conducted in game on AH2.  

I honestly don't have the knowledge I'd need to do in-depth testing, but I can take general statements from real reports, fly the two planes side by side and see if the statements match the results I get here.

I'll post more when I'm done, but the general idea is this

Take up Spit 5 and 190A5.  Compare dive speed, dive acceleration, zoom height (this one I may very well do myself, it isnt hard).  Try to find statements like the following

"When both aircraft are pulled up into a climb from a dive, the FW 190 draws away very rapidly and the pilot of the Spitfire has no hope of catching it. "  from http://www.odyssey.dircon.co.uk/VBv190.htm

and compare them to what we get in AH.  By the way, the above statement seems very accurate from my first test of 190A5 vs Spit 5.

"Ifthe Spitfire VB is 'bounced' it is thought unwise to evade by diving steeply, as the FW 190 will have little difficulty in catching up owing to its superiority in the dive. "

This statement does not appear to match up well with AH2 in game testing.. the Spit V actually pulls away from the 190A5 in our tests from 5k and 10k.

Anyway, we'll then switch planes and repeat the tests.  Then try the Spit 9 vs 190A5.

Dude, WHat Bug is that?

[Urchin]

The dive testing might be off due to the "net lag" effect.  

Seems as if whichever plane is in front pulls away from the back plane very slowly.  The 190 does retain its zoom advantage though, although the Spitfire gains during the zoom if it is in the back, the 190 gains much faster and actually out-zooms the spit.  At least when I'm flying it.

Going to try this a few more times.. the last dive & zoom from 5k the with the 190 in front, the Spitfire niether gained nor lost in the dive (lost initially, then gained back some as we bottomed out), but it stuck with the 190 in the zoom, losing no ground at all.

We probably the best test yet "form-wise" because both of us were purely vertical.

From 5K level flight 300mph indicated acccording to the E6B after 3 attempts per aircraft

The SpitIX drops a wing at 8500ft the 190A5 at 7400ft with little variance on each attempt.

But the Spit should outclimb the A5  more interesting is the stuff Urchin is doing.

[hitech]

Urchin, you have already proved the point. The spit is a good plane but dosn't have any overall drasticly different qualities. I.E. terms like antigrave do not aplly.

Why the back plane gains or drops back is net lag. Very simple to think of if you have 0.1 secs lag at 300 mph vs 0.1 secs lag at 100 mph, obviously the 0.1 secs lag with 200 mph differentc would equate to about 30 feet, 1 sec of lag would be 300 foot change.

One thing I've noticed is that the outer portion of the wing on spit v can be blown of, leaving the little stub and it can still be flown reasonably well i.e. can roll about its axis and land ok. Dunno if this is to be expected or not.

[Urchin]

Well, according to my solo tests, the 190A5 and Spit V match up pretty well with the test report.  

All speeds are indicated speeds (the white line speed).

Here is what I tested

Straight Zoom

190A5  / Spit 5 / Spit 9

Starting alt-------------speed----------------------finish alt
200 feet--------------200 mph ind---------2,000 / 2,000 / nt
200 ft-----------------250 mph ind---------2,700 / 2,600 /2,800
200 ft-----------------300 mph ind---------3,700 / 3,500 / 3,700
200 ft-----------------350 mph ind---------4,400 / not tested

Dive & Zoom

Starting alt------------start speed-----------finish alt
5,000 ft-----------------300 mph----------7,400 / 6,500 / 6,800 ft

The 190A5 has a marked advantage in the zoom climb coming out of a dive.  I used a 0-G dive for both planes. EDIT:  The 8,800 was a screw-up... that was the finish alt from a 300-mph zoom from 5k, not from a dive n zoom.  Note the P-47-D40 only got 6,700 feet out of a dive and zoom starting at 300 mph and 5k, I figured it would do better than that.  

Fuel burn rate was set to .01.  

I stand corrected.  I've got no reason to doubt the Spit 9 is modelled correctly, and I apoligize for insinuating overwise.

[Wotan]

Well there you go...

Now try and sell that to Mandoble......
