I've recently decided to start racing again as I've been out of the game for around 4 years or so, my god have things changed! I need new batteries and speedo but have no idea about these lipos as I was running nimh at the time with 6.5 R motor, I want to run 1/10th touring stock 13.5R but have no idea about these batteries or the new speedos.... Any help and advice would. E much appreciated
