If I recall from the pictures, Overkill uses belts from the motors to the wheels. Is that correct?

We rolled the dice and tried using MXL (really small) timing belts. The reason was because we could buy a pulley that comes stock with a hole small enough to fit directly onto a 550 shaft. I believe we are running a 12 tooth as the pinion on both of our shooter wheels, and then slightly different size pulleys to give us ~4000RPM and ~7000RPM output on 4 7/8" BB wheels.

We love the setup because of how simple it is. Small pulley on 550, slightly bigger pulley on shooter wheel shaft, timing belt between them, done. It also allowed for us to change wheel speeds down the road if we wanted to tweak something. Just a pulley/belt, or pulley/pulley swap to adjust speed up or down on either wheel.

In the future, ditch those silly belts and go to the promise land of 2mm gt2. It's more or less the same pitch (.079 versus .08"), but is far stronger (as you already know). SDP has a HUGE selection of plastic pulleys that we love for it.

This year's shooter and the last used 2mm. Love it.

Belts. We were already gearing the mini CIM up quite a bit so it's not much of a change.

Ah. That makes more sense.

Re: Team 254: World's Fastest Climb Teaser

Can't wait for the video and its less than an hour away from release.

Re: Team 254: World's Fastest Climb Teaser

All I can say is...wow.

I knew someone was going to make a climb video to "Started from the Bottom" :P

Good use of music :p
