So according to the above post and the rules, i cant run the GXR18...


or up to 3.0 cc (0.18 Cu In) KIT/RTR pull start engines.


If the engine come in the car when new, it can be up to and including a .18 engine, also an engine from another RTR car can be used as long as it's a .18or under.
Only after market engines have to be .12's, plus all engines need to be pull start or rota start.
