8. Identify the correct propeller from the counter-rotating pairs for the thruster being swapped. Under positive
voltage, viewed from above, thruster 0 rotates counter-clockwise and thruster 1 rotates clockwise. Select the
propeller such that positive voltage results in downward thrust. In the case of the high-efficiency propellers,
the prop labeled 5x4.6E is intended for thruster 0, and that labeled 5x4.6EP is intended for thruster 1.
9. Slide the propeller assembly on to the motor shaft and tighten the cap.
10. Place the propeller cover back in position and replace the screws holding it in place.
