Also, 12th scale, same thing. If I can't find a GenX10 soon enough, I'll order a GenX as everyone has them in stock. Pinion starters for these as well for 21.5.

Thanks!
I think we are running 96 tooth spur with a 35 pinion right now. Not sure if we are where we need to be or not yet. The kit comes with a 110 tooth spur I think, so a bigger pinion would be needed to get the same rollout. I am not sure what the biggest is that you can fit with that spur.

With the 1/12 17.5, we are running a rollout about 82 mm. I think I have a 45 pinion with a 76 spur, with a small tire. In Vegas, they were running 52/78 I think.

Not sure what you would need on a 21.5, but it is probably huge...
