There aren’t any that come with a gasoline burning engine. There are several options available that have Nitro engines in them, but none that are gasoline fueled. The smallest gasoline engine that I’m aware of is the big block .31 engine available in Team Losi 1/8th scale RC trucks and buggies/truggies. That engine is known for blowing conrods, so I’d not recommend it. Convert those models to Nitro or electric is the best option.
