Additional FeaturesI thought just a contactor, clutch, and gearbox would be enough for speed conotrol. It does work but the downside is higher energy consumption. Still thinking about a speed controller, too.
First successful road test 14 Feb 2009.
5.0 miles at 27 mph in 1st gear.
(Speedo cable problem at start of test repaired)
---------------
Addition test to 42 mph in 3rd gear on 28 Feb 2009.
---------------
At 50 mph, 3rd gear, 300 amps, 72 v., 26 June 2009.
---------------
Have driven it 165 miles so far - don't go out in the rain as VW engine louvers are open on top of the motor and contactors. Have to figure out a cover for that...
