hi all...ye, but the shaft dont fall out of the cup, even after its bent. and its not too far in either pin is half way up the cup slot.
its when i tumble over front to rear, then hit outside of rim against the ground the arms give but the shaft cant so it just bends.

so why do i need to fit revo axle carriers to use these shafts? or do you mean the hubs, due to the lager inner bearing?

as traxxas call what i call an inner diff casing they call an axle carrier? but they also call the hubs axle carriers too so im confused by it all...
i trust u mean i need part 4334 for a 3905? yes i know these will have to be changed (i need new ones anyway)
