Yea, I've seen that vid.

Balance on the blades looks perfect from what I can tell. Tracking looks good too.

It's really a low-speed wobble I guess. There is no shake at all when things are spun up, but I'm a bit confused by this because the bolt on top is definately moving around. (It's a blur, and the hole is not a defined dot if that makes sense. Tonight when I get home I'll get the skids light and see what that does. can't really think of what else could cause this. (Checked and/or replaced blades, main shaft, spindle,... checked balance on blades)

On another note. It looks like I'll have a TREX by this time next week, so I'll be joining the rest of the traitors in this thread. It will take a bit more time to acquire the rest of the heli (new radio gear mostly), so I won't be flying it any time soon, but it's the first step towards moving up.
