well took the heli out for a hover and couldn't get it to hold from spinning readjusted the tail tried again to no joy

the belt was loose I discovered and tightend it up tried again nope wasn't it either .

so I put my glasses on and had a good look and was amazed at what I saw

Well what I found was the drive gear coming off the main drive end was completely stripped no gear teeth at all

learn something new ever day

have ordered a new drive gear from helipros , align brand will see how it holds up

[19000rpm]

Amazing what a good pair of glasses can do.

Had that problem once or twice. Its solved by a torque tube, apparently. Something I don't have money for.
