Had same sort of problem it was the outer swash plate ring moving up and down caused 2 crashes and many parts. Ca ring back in place and my trex is happy once again. Might not be the problem but this condition caused erratic heli opperation.Did not even wait for the new swash to arrive, and when it does will inspect , the old swash came out of the box new, only 10 flights on align trex. hard lesson to learn
