Question

What could be causing this behaviour in my MCX


I've rebuilt and repaired a trashed MCX I picked up of eBay and I've got it flying pretty well now. I am however having a little difficulty getting it nicely trimmed for a stable hover.

If you imagine holding a weight on a bit of string and then gently swing it in a circle (like those kooky fortune tellers do). This is the motion my Heli makes when hovering; a kind of circular sway.

Any ideas what might be to blame or how to trim it out - my MCX2 literally hovers on the spot.

That's called TBE (toilet bowl effect) and a google will find tons of info on what it is and how to fix it.
