Anyone manage to improvise a good or workable solution for removing sticky pinions? Pictures would be nice if possible.

Thanks Long. I was hoping to use a rubberband, some chewing gum, and a ball point pen - MacGyver style. But I may have to break down and buy a puller.

So what's wrong with your motor? Doesn't it have a flat spot. I'm asking because my scorpion didn't and I snapped a screw driver trying to lever it up.

LOL, did you get loctite down the shaft? I find that heating it with small blowtorch (main gear off) and then an allen key in the grub srew hole while turning the motor can will work it off.

Nothing wrong. I just wanted to change the bearing because I know they don't last long. BTW, the bearing was bad. Motor runs 10F cooler now. Little more flight time now also.

I dremmeled a flat spot on the shaft.

That little puller in the RC Dude link wont work on anything bigger than about a 22mm motor. It doesnt have near enough "reach"

Yeah, I had that puller until I managed to break it. One of the problems I had with it is that my pinion sits too far down on the shaft so I didn't have enough room to slide the puller under the pinion.

Yea, that is what I meant by "Reach".

I havent been able to find a puller for big motors from an RC supplier.
