I live in philly suburbs to- Doylestown. I will like to race millville, and maybe ovrp, practice englishtown sometimes, don’t like that parking lot to much. So in millville I heard rotax most popular, second choice tag leopard, I heard guys from millville may switch rotax to x30 next year. Not sure why, i thought x30 better engine then leopard, smoother I read. Leopard top end faster maybe, mid maybe better x30. I don’t have one so can’t tell. And Vortex probably not good as Iame right?
