The AH-9 with Rotorlib feels way too underpowered. It can barely recover from a strafing dive if at all. I understand that it is a heavier aircraft with is armament, but its worse than the standard flight model. The M-900 is not much better. I can fly way more aggressively with the CH-67 right now. It's so easy to stall the blades when maneuvering.
