4.2 Pro
 

I got the 4.2 pro in my Zip Zap SE(its really for my microsizer pro which is coming tomorrow ) and it was really slow. Is it because the contact on the motor is not the zip zap one. Or do zip zaps have limitors or what?

...the SE is VERY HEAVY...u should see a diff. in the Ms pro!...:)

make sure to let us know how it does in the Pro
