Ija,
I had the "pleasure" to work with two brand new mechanisms this weekend! The moved the wrong way as compared with the original nose gear. Answer was just to rotate the control board! So, my friend got me to open the engine and turn the board around. To my (big) surprise, the PCB was just a raw PCB with no solder resist etc on it, looked like a prototype board (even though they were both brand new!). Amazing how one can sell stuff like that
