@lauren These have been game-changer in FIRST Robotics (#frc). I remember when the standard kit motors were just the cores of Bosch drills. Among their deligtful quirks is you got different velocity-per-volt (free spin) clockwise vs. counterclockwise, because *why would it matter*?
@mtomczak I have a 4.5 HP brushless motor here right now. The tech has really evolved!
