lower shaft slipping on gear

Well, it's not supposed to happen. There's a few ways you could fix this-an easy way, a more correct way, but still permanant, and the correct way. The easy way is to crimp the end with a pair of needle nose pliers, the more correct, but also permanant way would be to disassemble it, and glue on the gear, and the 100% correct way would be to put a new gear and/or shaft in.


If the heli's at the end of the lifespan, then A or B are decent options, but C's the one that anybody would actually recomend.

the lower rotor shaft is slipping in its gear.i can hold the gear and still turn the lower props.wont fly due to, i assume lower rotor spinning to slow.you think a drop of super glue would do it?or do i need a new gear?there is no knurled end on the shaft at the gear like there is on the upper(center)shaft.is this normal?
