University of Kansas engineers “hybrid” r/c car
With a little help from the fine folks at Pro-Line, The KU EcoHawks Team Slayer took a 1/8 scale nitro buggy and added a parallel brushless motor to make a truck that will run from the nitro engine, the brushless motor, or both at the same time. In addition to creating some special mounts for the engine, motor, and 3S LiPo, they also designed a special differential that balances the power output of the engine and motor when they are used together.
Pro-Line provided the wheels, tires, and body for testing and they have a complete article on their blog with more photos, video, and an interview with the team leader. It’s a very interesting read, check it out.
