I have a u can do 3D ep with a EF 370 5400kv 6.6/1 ratio gearbox with a pheonix 10. My radio system is a hitec feather with hs-55 on ailerons an hs-56 on rudder and unfortunately a hs-50 on my elevators. But before I had an hs-50 on my rudder. At first the problem was that only my rudder and sometimes rarely my throttle would glitch. I've decided to change receiver and tried an gws 6P. The same problem was there. So I put back my feather and switched my hs-50 to an hs-56. It works fine now but the problem is my elevators staring doing it too, but my throttle as stoped completely glitching at all, so the throttle is fine. Now the big problem is that my elevator just jumps around however it wants sometimes out of nowhere. I can fly with it but just not too low.

What do you guys think is my problem?

Thanks

You might have a bad servo that's causing the interference. Try unpluggin them one at a time to see which one is causing the problem. I'm not familiar with your receiver, but you might want to try a dual conversion receiver, assuming you don't already have one.

Try moving the receiver as far away from the speed control as possible that should help.

If all else fails, punt the motor and gearbox and go to a good no gear system, axi, hacker etc. There is no substitue for quality!
