Once this problem manifested in my EXI 450 with Hitec servoes,I replaced all servoes with EXI.Still glitching,so I re-binded radio,replaced
ESC,reciever,Gyro,tail servoe,motor in that order....Still get cyclic glitching
only when spooling up,if motor is not running I can level swash with ease no glitching. So I thought it was mabey static buildup from belt.Tried metal tail assy and drive block......still glitching. Thanks for any help you can give.

Could be the internal BEC on the ESC you are using just isn't supplying enough power to the servos.
Have you tried doing tests running the radio gear with a NiMH RX pack insted of using the BEC in the speed controler? Cheap ESC's come with Linear BEC's that are sketchy at best. Could also try bypassing the internal BEC with a external "Switching Mode" BEC.

The glitching is caused by the electrical generated from switching BEC of the ESC or from digital servo.
I had the same problem on on Corona digital servo. After I wrapped the lead around a ferrite ring, also glitches gone. Try it.

Tried both external battery pack and ferite core.even tried a diferent head to eliminate mech problems. I put the ferite core around the servo
leads. Mabey I should put it around the Throtle lead. Will try tommorow.
Thanks guys.

the ferrite ring should go on the lead from the ESC before it goes into the RX.
What radio do you have?
I had a friend with a DX8 that had a glitching problem, turns out there was a recall for that.
