after pulling off the rear axle probably 100 times, the plastic gets worn and the axle doesnt stay in place, which causes the gears not to touch, so heres what i did, i cut a very small piece of foam of some spare pieces i had from a tire set, pushed it into the axle recess on the side where its popping off, make sure its pushed in there far enough to touch axle but not so far that it binds it and wont turn, i used a small flat head screwdriver to wedge it in there, then i dropped a small bit of super glue on top of the foam to keep it in place, make sure you dont drop the glue on the actual axle or it wont turn at all, i held the foam down onto the axle with the same screwdriver while the glue cured, and it works perfect, its kind of a permanent fix, but with the setup i have in this rocket i dont need to ever remove that axle again, but if i did i could just cut away the foam, hope this helps someone!
