motor question
 

Do microsizer motors work in Zipzaps i have a Zipzap but want a faster motor will it work?

wont change much, my favorite motor for my zips and microsizers is the red zip motor

All ZZ motors work in MicroSizers, but not vice-versa, as the ZZ PCB supplies less power, so higher-end motors may not work in all ZZs. However, you can do the "no reverse" or dual-cell mods to fix that. :)

or if your pretty handy, swap pcb boards from the microsizer or bit into the zip zap chassis, best of both worlds, zip handling with bit speed

Yea there is no point in doing the motor swap.

and the red zip motor isonly a 2.35

no sorry its a 2.1 nos is 2.35
