Strange wiggle

[Helico-pteron]

Anyone come across a strange tail wag back and forth? Not wag from gain, but side to side as if you are moving it yourself. It varies from 1-2 inches and so far I can't seem to find the problem save tearing down the entire heli to kit form.

Swapped out tail servos and regulators and that didn't fix it.

Thoughts?

I'd check the engine first - just to make sure it's running very well. It seems that alot of people(myself included) chase tail problems when it's the motor. Also ensure your tail is setup to be neutral -no drift- in rate mode. Hope that helps.

Yup, the engine is suspect, but the tune is very good right now.

I am going to try a different pipe and see what that does.

check the set screw on the tail hub is nice and tight

What about the clutch, had any clutch issues?

Also I had something similar and it turned out to be the front bell-crank was loose and wobbling.

Ya, I'll check that.

Replaced the clutch too.

Well, preliminary testing showed that it was the pipe. I switch back to the Hatori and the wiggle seems to be gone, but it was a windy day so hard to tell.

The MP6 pipe has much more power than the Hatori, but I would rather not have it wiggle.

There are some loose bits in the MP6 so I may return it for a replacement.
