That's pretty cool. I don't know if it will make much of a performance increase with the extra rotational mass.

It really won't affect the preformance by much because electric motors have an "instant torque" and dont need the extra gear.

cool kit though

So how does that exactly work? Is it the centrifugal force that moves the smaller spur over the larger pinion?

Pretty cool--looks like it could be incorporated into a sprint 2 as well.

I've had one on an hpi pro2 and its ok for the first minute. after it starts to tump it doesn't engage the gear anymore.

but nice working finding one. what store sells it?

also when i had it the best pack out was a 1700mah so now days with high milly amps it should give a bigger kick.

can it be used with brushless? ahaha

1st gear runs off a oneway bearing and the 2nd gear runs off a centrifugal clutch so as the spurs hit enough rpm, the 2nd gear hits in and the oneway bearing disengages 1st gear.

hope that makes sense
