i got 2 jr 8411 in the tail for elevators
i got 1 hitec servo inside the fuse for rudder (5955)
I have the reciever just behind the rudder servo and right behind the tank i have the battery ( Doesnt weigh much though.
so yuh im guessing my jr servo may be alil too heavy
yea i still have the os 160, i have a hitec 8511 for throttle just a standard servo
