I have a knight 50 sport with the os 50 hyper. The last couple of times I've taken it out it has made a weird sound. It sounds like something is squeaking or vibrating. It only makes the sound some of the time while flying in the air. Today I put my bird in the dirt (first time). So I am in the repair process and all the bearings look good and feel smooth. What do I need to check that could be making the sound.

That is what I have read on other threads but I looked through my manual and I don't know what that is. If somebody could explain it to me so I can find the piece or post a pic that would be really helpful.

PS its is a knight sport does it still have this problem

On the clutch bell is a pinion gear (which drives the main gear). The top part of this gear fits into a bearing in a bearing block. The problem is that the pinion does not always fit securely into the inner race of that bearing, and will spin (then the bearing itself may or may not spin and the pinion spins inside the inner race, instead of turning the bearing), which makes the squealing noise. When you reassemble this part, put a little locktite on the interface between the pinion and this bearing, so that the locktite will "glue" the pinion to the inner race and thus make sure that they don't slip. This should fix the problem.

Thanks Let me make sure I've got this right. Someone please look at the attached picture and tell me if that is where you are to lock tite. So just locktite it and then install the starting shaft as normal. I also attached a pic so you can see the damage.

The first pic, yes that is where you put some locktite to fix it to the bearing.

As far as the second pic, I think you'll be needing locktite in many more places than just the pinion.
