RPM Hobbies is learning and growing the Oval program. Our track is a historic 85′, 8 lane Tri-Oval that has been roaming around Ohio for many many years. For our Sunday Oval Series we will run 2 Classes following the Ohio Oval Series Rules, with some minor modifications. If wanting to race in an official OOS event only minor modifications would be necessary.
