Ok,Ive always mounted them as far forward as possible,away from the mechanics and radio stuff.But Im old school,started out in 1990,stopped from 94 till just this year.I have a JR Venture cp30 that I bought half-assed assembled on Ebay,flies beautifully and the gyro is mounted at the top of the forward frame rail,just about 2 inches in front of main rotor.Its a JR 410t that I couldnt get to act right till I shut off the tail lock.
I also just finished a Century Bell 47g 50 and I put the Futaba 401 at the front of the servo tray.
Would it make any difference in performance to move either of these?
