I used to rely solely on the keyboard and mouse for the helicopter, but I bought a joystick to use for the plane. Now I use the joystick to control the pitch of the helicopter, and the keyboard to control the yaw and rotor speed. Otherwise, the stupid super sensitive "rudder" on the joystick makes me end up turning in weird directions. Other than that, hovering is so much easier now! And, I can actually dogfight with other planes with the joystick. Before I would just kinda hop in one and then eject over the opposite side of the map for a quick ride.
