It looks like for future proxies we at the Manx club are going to have to set the track between 10V and 12V for testing purposes to make a better choice of gearing as our track is the traditional 13.8V

13.8V to 10V is over a 25% drop in performance which could explain the 'slow', 'underpowered', 'lacking punch' comments we're seeing for some cars.

When I test for handling at Mid America Raceway, which is a routed wood track, I test at 13.8 volts.  I pick my motors based on RPM at 10volts. Stateside most proxy are set at 10-11.5 volts.  Quicker reaction time for drivers versus cars being too fast for drivers and fewer offs equal more fun.
