- Tachs: 5600 rpm @ 43.2v nominal (4500 rpm @ 36v; 6000 rpm @ 48v)
- Max amps drawn: 100A @ 43V
- Max watts drawn: ~ 4300 watts
- Speed: 45 kph top speed (at current gearing)
Electronic Speed Controller Castle Creations Phoenix HV-110 (link)
- 110 amps @ 50 volts limit
Throttle Magura 0-5K Potentiometer motorcycle twist grip throttle

Low Voltage (12/5VDC) Converters
  1. 12VDC converter using National Semiconductor LM2576HVT-12-ND buck-converter for motor cooling fan, front lighting (via 5vdc) and rear lighting
  2. 12 volt to 5VDC converter using MC34063 Based Switching Regulator for front lighting
  3. Another 12VDC converter using National Semiconductor LM2576HVT-12-ND buck-converter for ESC controller cooling
  4. Quark Pro BEC 3A UBEC for servo tester / RC components
