I purchased this product in addition to the Saitek pro flight yoke system to simulate a twin and it works very use.The caps levers are interchangeable and do little all possible configurations depending on the type of plane that you want emulate. It is possible to assign a reverse function in the red range of the flight simulator joystick but does not do this for each controller (no reverse for each motor). Below each lever is a two position switch for emulating all the functions that you want (flaps, gear ...). For setting I chose maximum sensitivity in Flight Simulator X. So do not hesitate because immersion is complete with these levers and with the rest of the range (Stick and rudder pedals) one believes in a real twin-engine aircraft!
