Good times last night.
Running four 4 minute heats last night in a 4wd buggy with a 4200mah battery without charging brought back the days of conserving your battery power. I had my throttle EPA down to 70% during the last round and I never let off the throttle, it was so slow I didn't have to.
It would be interesting to have a team based trophy race though it might be hard to enforce the no charging rule between heats if there was a large turn out. Unless there was hardcore policing after each run.
