Is CA good for glueing tail boom bearing
The manual suggests using silicone glue or shoe goop in tail boom bearing placement, However some people do use CA in theirs! I am using 3 bearings in mine, What is the best glue to use??

CA tends to be fairly fluid and can be hard to control around moving surfaces like linkages and bearings. You don't want any to get in to the rotating bearing surfaces or seals. Caulk-like glues are much easier to control and viscous enough that if any does get on a moving surface you stand a chance of being able to wipe it off before it can cause a problem. Also, the softer-setting glues will make it easier to remove the component if you need to do some R&R. If you CA the bearings in, odds are you'll have to destroy the boom to get them out...

Hey Reaz: This is what I hve done on my 2 90's. First, mark 3 equadistant spots on the tail drive shaft. Then clean the drive shaft, and the inner bearing races with isopropyl alcohol. Put a thin bead of CA glue around the places that you marked on the tail drive shaft, and slide the bearing over that spot, being careful not to get CA inside the bearing. Then let them set up for an hour. I have found no need to glue the outer white flange area into the tail boom, especially if your running 3 bearings as I do. Even after a couple of crashes, I have had no difficulty getting the drive shaft out of the boom, and the bearings have held tight on the drive shaft. If you ever need to remove the bearings off of the shaft, you can use a little acetone to soften the CA, and it will come off fairly easily. Good luck to ya :-)

Thanks RocketSled & Badger50, Liked your technique Badger also heeded Rockets advice. So in the end I have used 3 bearings & silicone sealant on the outer part of the bearing cups to "lock the bearings in place in the tube. I am happy with that outcome.
