FC99 do you know the drag formular?

I am working on it and found some problem in the speed.

I shall propose the result after double check


the formular is

Drag force (air friction to plane itself)

Drag= air drag coefficient*0.5*air density*air speed^2*wing demension

air drag coefficient should be the result from the lab and in Il2 data

can you just use the digit provided in Il2 software data?

coz your team are easier to dig out the date encoded

and see the difference in my simplified model between planes

(m*g-drag)/m
