That’s the problem with putting stupid power into a 1/10th scale truck. They’re not built for big block power. Traxxas isn’t known for building very strong transmissions. My stock 3.3 Jato eats 2spd hubs for lunch. I will have to lock it in 2nd gear with my drag mod 3.3 engine.

IMHO 1/8th scale engines belong in 1/8th scale trucks. Especially modified engines (and I don’t mean the eye candy mod engines some fellas sell).

I’m a biased jerk though. YMMV.
