Are you planning to run two of those planetary motors in the back ground of that one picture? I have one of them in the rear of my Tigercat(smaller motor in front) and it works pretty well. I'm running 165rpm motor with a 2.6:1 axle ratio and the speed is on the high end of usable with a nearly 8" tire. It could stand to have more power though. I would guess you will want this to be in the 30-40rpm range if you are using a direct drive so those motors would have more torque? What height are these tires again? KP used one big planetary motor in his 1/12 Kamatsu truck so two of these little guys should be close.

Give me a min, I'll go look.

You want it to be able to do this right?...https://youtu.be/LtbxUR9raN0?list=PL...PKlAqXQU81-vMh This has the 165rpm planetary in the rear. Motor is almost stalled but tires are slipping on rims.

I looked but none of the videos show it's speed very well. This is with two 152rpm gutless motors driving the axles(2.6:1)... https://www.youtube.com/watch?v=rAHZ...PKlAqXQU81-vMh
