raptor 50v2

[DrUAE]

I'm facing a problem with my raptor 50v2. When first apply the throttle before taking off, the head wobbles than becomes normal as the rpm goes higher. the same same problem comes back when í land the model. The rotor tracking is fine.What could be the problem? Any help is appreciated. Thank you.

What dampeners are you running? Is the head block loose on the main shaft?

[DrUAE]

Thanks for the reply clayk. I'm running the stock dampers and the head block isn't loose.

I would say it's because the dampeners are too stiff, but.....

What's your head speed tached at? or governed at?

Could also be tightness on the blade grips. If one grip is tighter than the other, they will wobble and semi-fold when spooling down/up.

Yep. Stand behind the heli with the blades straight out to the side and pull backwards evenly, if the flybar moves the blades are different tightness. They all do it to some extent though.
