Here is a demo showing a Servosila SC25R brushless motor controller connected to a Futaba RC radio and taking in a control PWM signal from a Futaba RC receiver. The controller drives a brushless motor equipped with an absolute encoder. This is a 'direct drive" setup useful for gyrostabilized applications, especially when paired with an autopilot such as a #Pixhawk or an #ArduPilot. The controller turns brushless motors with absolute encoders into jumbo RC servos controlled via RC PWM, USB or CAN interfaces. This demo was powered by a single LiPo battery.
