The Pilot seat is pretty much unusable. My Pitch, Yaw, Roll and Rudder Inputs do not work. I can only move the throttle around. Every other jet and helicopter works perfectly fine (ignoring the few issues with multicrew in the T-55, but that's offtopic).
Spawn in the EF-24G in multiplayer (I haven't tested singleplayer yet) and try moving around the multiple different Axis.
