proved to be quite effective and lot's of fun.
Two 3V relays send the power directly the hopper motor to bypass the rather weak transistors on the
circuit board. That orange thing connected to the motor is a capacitor to get rid of interference
with the RC unit.
A cheap micro servo capable of lifting 1.5kg directly connected to a single "cylinder's ram" lifts and lowers the
