Re: [FTC]: Can I add non-slip material to 4" Tetrix Wheels?

I was able to borrow some 80T gears yesterday!

1. Replaced the 3 40T center gears and their axles with one 80T. This also allowed us to eliminate the spacers under the motor mounts and gave us some adjustment range between the two motor gears and the driven gears. This drive train runs smoother and feels "right".

2. Wheel base increased from our original 10" to 11.25". We tried eliminating the remaining two small gears (the next increment smaller) but couldn't get the gears to mesh correctly. I'm okay with the increase.

3. I think the larger gears might run a little truer when all four bolts are used on their hubs. I don't think it matters with the 40T gear.
