700 DFC tail issue

[Chewy700]

I found one of the reasons i had a harmonic vibration on my brand new 700e dfc pro was because the bearings on the torque tube were not glued perfectly square

I'm not sure but I think my one way bearing might be slipping

The sleeve inside the one-way hub is known to slip. Some have had success removing it and applying red thread lock. There is also a post about securing it with a grub. KDE also makes a replacement hub that eliminates the sleeve completely.

Thanks I did the grub screw mod to lock down the outer race of the OWB that fixed it. Thanks for the help guys my mouth long battle with this heli has finally come to a end.
