The one-way bearing is locking up during each flight. Doesn't take much to free it again, just don't think it should do this. It was lubed when assembled. The heli is only four flights old. Any ideas prior replacing it?

Djoyce,

Not sure if you fix it already? I was chasing the same problem but after a crash on my X4 which uses the same parts as 425/550.
It turn out that the one way bearing cracked and I didn't realised it as it turn freely on its own and lock out only when everything is fixed up. Replaced it and it is free turning now and smooth.
