I have a high pitch squeal in my new N5c. Swapping parts with my other one, which is fine, I am pretty sure it is coming from the clutch bearing block 110-155. I was going to replace all the bearings and the block itself.
But - mine in machined metal, versus the one in the manual that is two halves joined with hex standoffs. I am wondering if the outer race is slipping at high speeds, ~1500 seems to make it happen.
Is there a different number for the metal one I have ---or--- can I use the one listed in the book ?
tnx, Pete
btw - I love the N5c - best heli I ever owned!!!!!
