XTM Rage 1/18th Monster Truck

[MetalMan]

I've also been running my truck for a while, but I don't think it likes being powered by an outrunner...

In the front diff, a single tooth was stripped from the ring gear. In the rear, a tooth was stripped from the diff pinion gear. Also, at some point the motor must have shifted (despite heavy tightening of the motor mount screws), and that stripped the spur. Surprisingly the internal diff gears are fine. So, one bag of parts fixed all of this. And I packed the diff gears with Traxxas lithium grease, to help decrease the diff action.

At the same time as I replaced the gears, I also added some HPI touring tires and wheels (6mm offset 26mm wheels with X-Pattern Radial tires in D Compound) and installed the 22t 48p metric pinion that finally came in. All I can say is WOW. The truck took off SO fast, and had an awesome top end speed. If I punched it hard enough, the truck just couldn't handle it, and flipped over from diffing out (I think because of the torque twist). On one such occasion, the truck tumbled at least 5 times, and snapped a rear toe-link ball stud in the rear bumper.

So now I not only need a front bumper, but also a rear bumper and a ball stud.
