X50 tail buzzing

Gscott · 12-05-2012, 07:54 AM

I have been having an issue with my x50 that I can't track down. The tail makes a loud buzzing under load. I have tried numerous tail blades and even mounted an Align v2 hub and grips but the issue still persists. Today I noticed play with the rear input gear assembly in the tail case. I can move the gear in and out about 1mm and I can also spin the bearing in the tail case. I disassembled the tail tonight and noticed the bearings and spacer for the input bevel gear are not a tight fit in the tail case. Anyone else have this issue? How tight should the bearings and spacer fit in the tail case?

It sounds like the drive shaft is fluttering. Check your bearing placement and may be even add another bearing to the shaft.

Mine had a similar probem then I heard that the X50's have insufficient torque tube support so I did the double bearing up grade almost right away. Never had a probelm since
