Hi,Im trying to improve the FM on the Alphasim Aardvark. The problem is that although it can hit mach 2.2@ high altitude, it also does this at sea level. I have toyed with the paramaters in engine section of the .cfg, but those result in the speed dropping to M1.2 at altitude as well as at sea level. Anyone here know if this can be done by just tweaking the .cfg, or would something like rewriting the airfile with the 1% process be necessary?

Try to adjust the #1502, 1503 and 1504 items with the airedit program. These items will change the CN1 and CN2 with IAP. Reducing the thrust at highers IAP, you will reduce the mach number at lower altitude. Check the avhistory forum. They are "monsters" in that questions. EnjoyJose
