I'm doing the initial build of the heli and I'm at the torque tube and I wanted to get an opinion on using CA on the bearing to the torque tube as in the instructions.

I didn't use it based on the significant amount of stress it would take to move that bearing in any fashion.

I see it as a crash move only item.

I moistened the rubber dampener that supports the bearing and I use a large T handle wrench I had to push it down the tube half way. The T wrench was large enough to push on the rubber only and evenly.

I can't see that bearing going anywhere unless I crash it and even then...

Thoughts?

It's glued for a reason

There is probably 2 reasons to glue it to the torque tube. One being so it will not wander or move down the shaft to the ends and the other is so the bearing inner race is not galling against the torque tube eventually cutting throught it
By gluing it to the shaft the bearing is riding on the inside balls like it's supposed to do. I have found that if you only use minimal CA you can break the bearing loose after a crash so you can reuse it again and again if it's not dammaged. Just wipe a little on the tube with your finger so not to get any into the bearing.

Oh No Someone Please Stop Me Before I Go Broke With This Heli Thing!!

fair enough, tomorrow I'll grab some of the super thin CA and glue it.

Thank you
