I wish they'd fix it tho, as you can pull IN a flap if it's still there, but you often can NOT leave the other flap out. If you want to get out of a fight that means a dive and/or speed, but with a stuck flap that means losing control and/or an uncontrollable spinning dive.
When a flap gets shot off it should STOP affecting the plane!
What HTC needs to do is to code the missing flap to fully retract when it's shot off. Doesn't seem that hard a solution.
