Brian, I got your input. I think if they are running this motor with 3700 batteries, they could run a 15 minute race. I am hoping they will see the advantage to moving over to motors such as the ROAR stock formulae so they can experience the wonderfull performance these motors offer. Bare in mind that the current ROAR stock motors run as fast in the current 1/12 chassis with the new batteries as the full modified motors ran in 1/12 scale in 1996. I am privy to data from some radar measurements that support that.
