K Wish I had something more, but that's going to be a pretty clear mechanical prob. Much easier to take the head apart and reassemble carefully than try to debug by remote .

The Kasama head isn't that much better in flight by the way, unless you're really flying it out. It's tighter at extreme pitch/cyclic, and it has reduced travel so you don't risk hitting the canopy with the flybar, and it's darn near bulletproof when you crash, but you don't really see a difference otherwise. I'm still not sure it's worth the money.
