I have a new Walkera V200D03 FBL heli. I have a few short flights on it and the reason the flights have been short is that as I get up in altitude (3 feet or so), I start getting TBE so eiither I land it or crash it. What's the best way to correct TBE on a FBL heli? The blade tracking seems to be OK.

I find the same with my MSr (still hate the tail motor) if I fly indoors. Outside take it up 2M and it's hands off steady. (Probably the same in a big hall!) The heli causes a lot of moving air flying in a smallish room and I'm sure this is the cause of TBE. Well it seems that way to me. Even my micro quad is more stable outside than in my work room. Wanders about unpredictably but no TBE like the MSr.

thanks for your reply tombo. I've been flying my V200D03 outdoors so the turbulence problem you're describing should not be a problem.

OK Crasher,

We can only hope that someone who really knows this model will come in to help.

Tom.

hello crasher47

I had a trawl and found these youtube videos on TBE.

From those, the problem would seem to be lack of free movement at the blade holder ball-links and pitch links in the guide slots of the rotor housing. Also check the movement of the blade holders on the feathering shaft.
Check the vertical alinement of the link rods up through the guide slots. The rotor housing may have just twisted on the main shaft just enough to cause the link-rods to bind in the guide slots, and check that the rotor housing fixing screw is tight.
