I just upped my headspeed to around 2600 and I'm getting a wierd problem.

First the heli starts to bob forward and back - like nodding. But then it starts to irregularly jerk forward and backward, never side to side. And then it bounces up and down as if I were jerking the collective up and down.

What's really wierd is that as the battery goes down a bit the problem goes away.

This doesn't sound like a typical nodding problem because it happens at higher headspeed, not lower headspeed.

So I'm thinking it's a problem with the servo that connects to the rear ccpm link but when the whole swash jinks up and down it must be all three servos.

Anyone ever had a problem like this? Seems like the higher head speed is causing glitches.

I've also just added uH blade grips - I'm not sure how they would create the problem though.

Mega 16/15/3, cc35, electron6, ferrite ring, 335 woodies, metal head, new uH grips

Helichomper,

What is especially wierd though is than the jinking is always forward/back or up/down but never right/left. Was your situation like that too?

I'll try tightening. Thanks.
