Now that I mentioned it in another thread, I did a little test on negative G performance of AH planes.
I flew at 5k alt, trimmed for level flight at 200 IAS. With WEP on, I tried to do an inverted loop (rolling 180 degrees and pushing through the Immelmann maneuver). All planes had 25% fuel, no drop tank.
This was mainly done to test 109 capabilities, and they are dissapointing. In fact, every single fighter in AH can do outside loop better (faster) than 109, if trimmed for level flight at 200 mph IAS. How much better (faster) ? Well, pretty much, because 109 can’t do it if trimmed for level flight at 200 IAS, and all other fighters can. 109 has to be trimmed nose heavy to do it.
Also, every single fighter does nose push down more readily than 109. 109 has to be trimmed nose heavy to do it the way other fighters in AH can do it.
The difference in negative Gs that can be attained in nose down push between P 51 and 109 is approximately 1 G, both for level trimmed flight and nose heavy trim.
Is this really accurate ? Is it just the difference in trim (elevator) maximum deflection, or something else ?
Disclaimer: I am biased to 109. The test I did was done in about 20 minutes, so it is pretty inaccurate, but it gives some comparative relationships.
