I am building the 450 and picked up a 401 yesterday. I asked about mounting it and i was told NOT to put it on the bottom shelf becuase the motor would cause interference. he suggested i put it behind the motor on the rear of the heli. this isnt that much further from the motor. the problem is the assembly manual says the front is fine.

I really only want to mount it once so please chime in with advice.

thanks all
