Will there be cooling issues

[squeeforever]

The biggest spur for the Revo is a 40T. Also, why would you want a 44T? Thats to big...Your gonna need to go as small as possible on the spur and probably as big as possible on the pinion if you go with the Slipperential...Anywho, I would go with the buggy diffs, a 7XL, 4S LiPo, and somewhere around a 18T pinion. You should get around 39 mph without the tires ballooning (if the tires balloon slightly, you will gain a mph or two...). With a 20T, somewhere around 43...That should be about right...
