First test drive I built the quad in parallel to the grey quad. It has a rear axle with differential and retrofitted disc brakes. The rear axle is suspended as a swing axle. The front axle has a cross leaf suspension (used ski) and two self-made front wheel gear motors. I also have a self-made torque sensor that measures the chain tension. I used all kinds of e-bike and bicycle parts and metal profiles.
