Surely there's enough people interested in Boise to do a winter on-road program with 6-10 races per year?

I've asked around, not a big following here. From what I've been told it been tried a few different times but soon after falls out of favor. Indoor offroad on carpet is all the rage here now, it's fun but nothing like 1/12 racing. I'm hoping to get up there once this season for a race.

If you order it like I did and add the chassis and the rest of the parts it was more than that. The car works very good on Black carpet as most of the racers in our new class GT12 USA are running different forms of the CRC chassis.

Any consensus on standard mounting versus over axle mounting of the Sanwa SRG-HR servo?

Questions about gearing ratio. I'm currently running 49/72 gearing on my CK25, GT12 class. That gear ratio is 1.47. Is it "better" to run larger gears with a similar ratio? Or is the ratio all that matters? I was considering if something like 55/80 would be better. I purposefully left out tire diameter as I'm not figuring rollout. Just a general question about gearing ratio.

Also is there a better brand spur gear to use? I currently use the CRC brand spur and pinion with 2.5mm balls included with kit. I added the CRC lightened diff rings.

Going to larger gears for the same overall ratio will increase overall mass (albeit a very small increase) as well as increase rotational mass. Larger overall gears will however move the heaviest part of the pod (the motor) closer to the pivot point, which is generally a good thing.

I'm not a fan of the CRC 3/32" ball spur gears. They have never been nearly as smooth as a 12-ball 1/8" gear for me and I've had binding issues with the lip they use where the bearing fits into the spur. I currently use Axon spurs in stock class, but have had good luck in the past with PRS, Xenon (16-ball 1/8") and RW spur gears as well.

Spur gears- Kimbrough.I've used them for many years.I even made a Kimbrough spur gear to work on my xray grear diff. Been using it for several weeks and it works fine.
We run 57-59x76 with our GT12 class.

I've always been curious about these bodies... The front seems to be as large as lola bodies, but what kind of tyres are you using in the rear? Same as "lola" 1/12th or specific narrower tyres?
