A VERY simple solution to On-road is to get BACK to pan cars!! They are two wheel drive---handle GREAT--with a minimum of bearings / A arms and parts to break. You can run 1/10 with 2s lipos and 1/12 with 1s lipos and have a LOT of fun without a huge expense. Even the tires are MUCH cheaper then your average rubber sedan tires. I've never understood WHY people don't race these cars more---their FASTER than the sedan cars-- EASIER to setup---and CHEAPER to run!!! So why not--"Back to the FUTURE"?????
FWIW
