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
