It lessens markedly when the gyro is in the 'On' mode.
The worst of it is when inputting left aileron with the gyro in the 'off' state - man the servo jumps around like a jack hammer!
Also tried it in a Turnigy 9X upgraded with Sky9X mainboard running FrSky DJT and a D8R-XP RX - jittering just the same.
Then tried it in an old 35meg Futaba T6EX - working fine with no jittering at all.
Tried all three gyros I have and all the same. Will look at it all again tomorrow.
Mine was doing the same thing with an Aurora A-9. I replaced the Y connector to the ailerons from a heavy duty Hitec to a cheap HK one and it solved the jittering. I was stumped too and changed the Y connector by pure luck as I noticed that when I unplugged the ailerons it stopped.
