Demonstrating some utilities for the 3d-printed Halbach motor: Method for static balancing, drill-press-method for measuring Kv, rotating motor-mount for measuring the torque, and calculating the efficiency (it's over 80%). Finally packing the motor in a box, and shipping it to the FliteTest guys. Hopefully they make it fly! :-)
