Hello Chris
It will be nice to see you back racing at Ribble. Yes the kit has changed quite a lot since you last raced.
We run Mardaves with 4 cells, diffs are ok as well as ball raced front axles you can run any esc you like but you must use a Mardave chassis. All the rules are on our website
www.rvrccc.co.uk
Come down any Friday night and have a look around you will be more than welcome.
