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...

It is licensed, titled, insured, and running.
