I don't have any JB-Weld to glue the ends on, would JB-Kwik or 30 Minute epoxy be sufficent? I have to drive like 1/2 an hour to civilization to buy regular JB-Weld...

i used 30min epoxy and it workes fine.. fore extra safty i drilled a 1mm hole all the way trough the alu. end and the carbon pushrod and then i glued inn an 1mm pinn.

but i realy think it would be fine with just the epoxy aswell...

Stay tuned fore more happy days

The 1mm pin is a good idea, but my ends are titanium, and I don't have any drill bits that small that would drill that... .

This may sound like a stupid question, but if I don't ask I won't find out. So why is it recommended to use JB weld on Carbon Fiber and whatever instead of thin ca glue? Is it that the ca will crack and break away from vibration of the parts? Or is there some other reason?

IMO the various 2-part epoxies with reasonable curing times (1/2 hour or more) are all stronger than CA. We use CA so widely because it is fairly strong, cures almost instantly and that is VERY convenient.

you want to try to rough up and then alcohol clean the inside
of the tube so the epoxy has something to grab to.

Be careful that the ends of the carbon rods easily clear the socket heads on the tail case and won't vibrate into them in any way. Otherwise you may find yourself tracking down rf problems and hopefully or worse. Many use the hoops and wires for this reason.

I had a pretty hard hit with the Quick UK tail pushrod setup on my R50 which wiped out my 9254 . I've not replaced the carbon pushrod which broke but put the tail servo back at the front and I can't really tell any difference (maybe I'm just not that good ) but it sure does feel safer and doesn't get covered in oil & dust.
