Claims1
It was found that a car or a truck starter motor will compel a heavy object forward. The car weight between 5 lb to 2000 lb+. The test was done with a car starter.
- It could not be balance with motor on one side due to car differential that spends both wheels. We concluded that dual motors was needed to balance the motion and weight forward. This is know as 4×4 All Wheel Drive.
- The motor is a high amp and high voltage motor which handle the stress of weight without burnout from 5 lb to 2000+lbs.
