Another question:
When rotating the rotor, it seems tight and doesnt spin freely. Before installing the tailboom, the mainshaft was what would be expected. The tail shaft turns freely when not in the belt. All associated bearings (idlers and such) are free and smooth. I get the idea it's the belt drive. So, I checked to ensure its not twisted in the boom and other typical mistakes made when you're excited to get the thing together.
Is the belt drive just tight on these?
Also, I read (somewhere) that the belt should be lubed with silicone spray. Why is that? I never did that on all my other belt drive helis.
Thanks again!
