The real trucks are Diesel powered.

Anyway, they're talking about using RC car and airplane engines. Which run on nitromethanol, and are still too big to go into the 1/87 scale TTTT's. If they tried with 1/35 scale they could probably cram in a tiny engine and fuel tank. But I don't think it would work well even then.

If any of us could afford a real Trial Truck, I doubt we'd be on here building these.
