The YR shaft has now been threadlocked. Jazriders were sealed so you're not unable disassemble them.

Currently running a 9T motor for an indoor track. I know there are some brands that offer universals with a thinner shaft but you'd need to couple it with a smaller drive cup. Would the only advantage of these would be its lighter weight but then at the same time not be as strong, having a narrower shaft?

Has anyone used the Tamiya universals?

The YeahRacing shaft is of the same design which I'd think be ok as long as I loctite the grub screw?

GPM also make a set but of a different design..
