I don't quite understand what you want to do, but if you want to run 1/10 Oval AND road coarse, an L3O will do both, you can run with the batteries on one side for oval and split them for on road in a 3_3 setup.
Pan cars are simple and Fast! . They don't break much at all. I started with a bolink for $30.00, now I have an L2.5 (L2 with 3 shock setup), a Wide Pantoura (Roadkill 10) and an L3O I only use for road course.
