Help!
Motrolfly problem -- Help! Video in thread

Hello everyone! A week ago I had an aileron servo lock up so I had to make a forced landing. The airplane sort of pancaked in (the airframe is fine -- that you RCMC!) but I did NOT have a prop-strike. That was 8-9 days ago. Today I took my Slick out for the first time since the forced-landing. The motor is a Motrolfly 4315-480

I noticed in my run-up that my spinner and prop moved forward at full throttle. I took the cowling off and this is what I found. I checked ALL of the screws and everything is tight. So what is going on?? :

Click on the picture for the video! (

The wheel collar on the motor shaft at the back of the motor has moved. I think the motor back plate has to be removed to get good access to tighten the wheel collar.

I was able to loosen the set screws and move it flush with the bearing (??) on the back. That fixed the problem, bit you could hear the collar ribbing the bearing (??) I did that at the field, but once I heard the rubbing, I moved it back

Incidentally, you have two threads which are titled to look like 'product failure' threads which are actually 'crash damage' threads instead.

I just got finished reading the one on the Hitec servo, too.
I know the titles are technically correct. Just sayin.

The way things usually go around here, my thought when clicking on each was that it was going to be yet another 'don't buy this product' thread.

I did not exactly know if it was a product failure or not. Sorry for the confusion.
