this stood out for me when I read the readme, surely the drag was modelled before? it certainly felt like it.
The drag effects could certainly be felt (before the update). I'm not sure why they increased the drag or weight. I just double checked the weight of the rockets and rails on the Mossi Mk IV and the Typhoon...
the 8/60lb rockets weigh the same on both planes: 640 lbs (btw, that is a LOT of destructive power for only 640 lbs of weight)
The rails on the Mossi weight 240 lbs, the rails on the Typhoon weight 480 lbs. I wonder why the difference?
Disclaimer: I refuse to allow HTC to increase the weight of the rails on the Mossi. It is forbidden.
