Hey guys!

I have a problem with my CX2. the last couple of times that I have flown it, it wants to move around, impossible to hover, I have tried to set the trims and such to no avail. and after a few minutes of trying to straiten it out, the blades hit and fly into pieces! I know that there may be an issue with the blades are not tracking correctly, how do you correct this on the CX/CX2? Please help, I want to learn how to fly and this is not helping.
