My manual shows nothing about using locktite on the main shaft bearings. Should I use some green locktite on the main shaft bearings after assembly?

if you are referring to using the Locktite to glue the Bearings to the Main Shaft you don't need to

I'm not really sure if you are referring to using Loctite on the main shaft bearing block bolts or actually using loctite on the shaft to keep it from sliding out of the bearing race.

If you are talking about the bearing block bolts, then the answer is yes, you can and should use loctite. It's better to use blue Loctite so you can get it loose if you have to replace anything.

If you talking about loctiting your shaft then no...don't do that. If you ever need to remove the shaft from the bearing, you'll have a very rough experience and end up having to replace both.

Your best bet it to try and only use Loctite where it's needed. Loctite is not good if it gets into your bearings. It can ruin your bearings. If you manual doesn't call for it, then just make sure it's locked down before you fly and check it reguarly in case is starts to back out.

Where To Use
The rule I have always used is that if it is a metal bolt going into metal, use blue loctite... if it is a screw, going into plastic or that type of material, I use white canopy glue (Old name RC56)... As for locking the shafts to the center race of the bearings, seems to be mostly "old school" and not done that much anymore....I still use this technique on my Vario scale machines that I do not expect to be taking apart much once they are built and flying... but with the new 3D type flying that is now the "norm", things need to be able to be taken apart and repaired easily and I would imagine that is the reason that this step has been omitted....

Good Luck and welcome to a GREAT HOBBY/SPORT (ADDICTION!!!!!)..... Stan

Works great on a few pinions made of softer metal, but with main shafts I wouldn't bother, they don't wallow out against the inner race.
