After control surfaces are hooked up and zeroed, the stick has to be cut so that it does not hit the throttle when it is in the idle position. All the way back. The co pilot stick is removalble and it has to be drilled in the socket so a pin can be put in place to hold the stick. When both sticks are cut to height, then the grips can be installed and wired. Both sticks have aileron and elevator trim and a push to talk switch for radios.
