Deep Dive: Division V4 Design (Flywheel, Hubmotor, and more!)

This video is a long and detailed look at the design choices I made for Division V4 - my lastest beetleweight combat robot. Division V4 features a custom hubmotor weapon system, friction-driven flywheel counter-gyro, and many other unique design elements. Thanks again to PCBWay for making the flywheel for Division V4!
