I just finished setting up my 401. The directions stink to someone who is fairly new at owning an "upper-end" gyro (like me).

You can download the instructions from Futaba's website free of charge. Or, if you are more specific I will help you as much as i can.

As far as orientation of the gyro and mounting it on the heli I do not think it matters which end the cables face. What matters most is that the pot switches are facing UP.

Is that what you meant?
