FM has not been adjusted according toPyro's comments on this board...
kweassa is correct, in the new plane models the bomb racks exert drag unlike in the past.
since the ki84, b24, p38 series, and 190 series are the only ones modeled ot AHII standarde, they "suffer" from the newly inputted drag
though i will say if kewassa's tests were right, i think the 190 d9 suffers a it much un-due drag from a simple drop tank rack.. losing 14 mph because of that tiny thing????
