Vehicle Chibi-Mikuvan
Modeled after a 1989 Mitsubishi Delica in
1/3.14 scale with custom fiberglass-sandwich
composite bodywork
MotorTurnigy Aquastar T20 Brushless DC
A high speed electric boat inrunner that's
watercooled being purposefully run at a very
high 22:1 gear ratio to enable positive
starting behavior
DrivetrainRear wheel drive
ControllerTurnigy Trackstar 200
Designed for 1/5-scale R/C models, it was
determined that 1/3.14 scale was close
enough. The controller's starting routine
is designed for inertial (ground) loads
and with the very high gear ratio, greatly
reduces the starting "cogging" or
stuttering behavior commonly seen in R/C
part based powertrains
Batteries24, 1.20 Volt, Nickel-Metal Hydride
Battery modules were salvage from a 2010
Ford Fusion Hybrid battery, which contains
28 modules with two 4.8V, 8Ah D-cell NiMh
assemblies each. Six modules were used
resulting in a 28.8v 16Ah battery.
System Voltage29 Volts
ChargerHyperion 1420i
Common multicharger for R/C models
DC/DC Converter
A "5V BEC" for R/C models modified to output
12V at up to 1.5A
InstrumentationCustom (V, A, W, Wh)
Top Speed25 MPH (40 KPH)
As-terminated in Wye
Acceleration< 3 seconds
Range8 Miles (12 Kilometers)
Hypothetical (calculated)
Seating Capacity1?!
Curb Weight113 Pounds (51 Kilograms)
Battery module weighs 22 pounds
Tires8" Harbor Freight Pink Tires for America
