Heli wobbles during flight
I have a Falcon 40 heli which I've been using for flight practice and I'm having a problem. The heli has developed a terrible wobble motion which can be observed as soon as any throttle is applied. I recently crashed so I've done some work including leveling the swashplate, adjusting the flybar and paddles and I've got new and balanced blades. The main shaft doesn't look bent but I think I'll order a new one anyways since I've crashed this heli at least four times now. I don't know what else to check. Does anyone know why it's doing this? I've provided a video below.
