After work today I came home to three freshly charged batteries and my CX2 waiting for me. This is the first time this has ever happened to me, but as I would fly forward the nose would stay straight but the entire bird would strafe left as it moved forward. I went through the usual: blade damage, warped blades, balance, and couldn't find anything unusual. Checked for friction in the drives, all clear there. Can't think of what else it could be. Anyone have this happen to them? Fixes???

Your swashplate is off.
Check to make sure that its not seperated and that its level.

That did it. Thanks!!!

I have the same problem and my swashplate is leveled. My CX2 hovers great with the trims centered. I have been through all the other stuff also: shafts are streight, blades balanced, upper blades are in track, etc. Anyone got any ideas?

wxup,
Mine was the same way. Trims centered, hovered great. No issues other than when I gave forward input the heli drifted left. My swashplate looked level too. I landed the heli trimmed the aileron right to counter the left drift and that did it. Still hovered great and straight as an arrow in forward flight.

My first thought was that if I trim the aileron right it would cause the heli to hover right. This wasn't the case. I think that the little amount of trim was just enough to "level" the swashplate. By eye it still looks like it is in the same position.

The coaxial blades make it fly to the left. You should also notice the nose dipping to the left, especially with agressive forward flight. The top blades don't get exactly the same airflow.

All you have to do to get straight fight is give it a little right aileron when you are moving forward. Pretty easy once you have tried it a few times. You just need to move the stick a little diagonally ( towards about 2 o'clock) instead of just straight forward.

Intersting I get Fwd/right/ and DOWN! IT takes a big dive down. It almost acts like my swash is out of, um, square? Because I get back/left/ and down. and left right also induce some forward/back. Am I royally screwed? is my hub to high/low ( CF shaft, no locator holes.) of is my swash just way off? It hovers, not hands off, but well.

If it hovers OK without TBE then I would guess that your hub could be too low. The links will actually hit the motors, especially when you lean the swash plate forward. I would measure the stock outer shaft hole locations and drill locator holes in your carbon fiber shaft. Do the following:

Put your rotor hub on the old stock shaft and tighten the upper locating set screws in the locator holes. Then measure from the top edge of the hub to the top of the shaft. Now place the rotor hub on your CF shaft at the same height. Tighten the top set screws to make marks in the CF. It's trick to get the drill perfectly centered when you drill through the shaft. So I just drill a hole in the middle of the mark on each side rather than trying to run the drill all the way through. Keep the locating holes small because they will weaken the shaft.

Then level the swash plate and you should be good to go.
