Im not complaining. I just want to know if Im doing something wrong. Most sources state top speed of the A6m2 zero 21 at 533km/hr at 4500m. So I went to 4500m in QMB with cockpit off and read the true airspeed. And with 25% fuel and rad closed,could not get her over 490 kph at 4500m while flying level. I was on both the crimea and the smolensk maps. Am I missing something?

Any ideas or suggestions?

thanks

can't say like that, but:

- what mixture you use at that altitude?

- do you use the second stage of the compressor?

- what prop pitch?

- is your ball perfectly centered?

- do you have to make some inputs with your stick when flying (or in other words: is your plane perfectly trimmed?)


testing top speed of an aircraft is a very precise work, and the slightest mistake can make your results false http://ubbxforums.ubi.com/infopop/emoticons/icon_wink.gif

No, I know all that. At 4500 m need second stage compressor, although zero 21 did not have two stage compressor. Mix at 80% gives higher hp. Varied prop pitch. I tried the test 5 times. Never got it over 490kph true. Zero 21 should do 533km/hr at that alt.
Don't know if its bug or not. Oleg said he would fix the supercharger error and ammo loadout for type 99 cannons. Also, zero had no hp augmentation like wep or boost in the model 21
