I decided to take my CX2 outside for a flight yesterday, but during flight the wind caught it and started to carry it away, before I knew what was happening it was a couple hundred feet in the air and a couple hundred feet away. I decided as it was approaching a crowded parking lot, knowing it was un-recoverable, I decided to kill the power before it made it over the parking lot and hurt someone. I ended up damaging the Battery & Battery Holder, Outer Shaft, Inner shaft, Flybar, Upper and Lower Blades, Lower Rotor Head, and the outter canopy was a complete loss. The heatsink was dented, and the 4-1 controller had a small dent in it (circuit board looks undamaged).

I ended up with some major damage, but have since replaced all damaged parts, with new parts. However, after I replaced the parts I took it into my living room to test fly it and now it is all over the place. I tried adjusting the pots, and attempted to re-trim the remote, but evertime it takes off I can barely control it. I tried the "Support by flybar" trick to make sure it was balanced, and it is, and I never had trouble before this happened. So any help or suggestions would be appreciated.

Have you checked yur servos to see if they have been stripped in any way ?

I take it the swashplate was already levelled out

If its that uncontrollable i would think servo problem or maybe gyro bust

Sounds like your swash plate suffered some damage in the crash.

Ye good point has it seperated ?

Well before it crashed, I had replaced the plastic swashplate with an aluminum one, which appears to be unbent or broken, which is why I didn't replace it. I did try to level the swashplate as best as I could, but it still seems to be having some issues. It could be I'm just not leveling it good enough, is there a trick to this? If the gyro is bad, is there an easy way to check?

Thanks for link, it turns out it WAS the swashplate, as it wasnt really level, which really helped me dial in the elevator and alieron trim. I am still getting a pretty good left hand yaw, even with the pots all the way counter-clockwise and my trim set full left, but it is managable.

Yaw can be cause by many different things. 1. Blades 2. Bents shafts 3. Loose locking screws 4. Motors 5. Gear Mesh. 6. Bearings.
If you want to try and fine tune it then read these links.
