My selection was the Model Motors Extreme, a small brushless motor with integral 6:1 gearbox and cooling fins. It turns an AeroNaut 13 x 8 propeller and weighs just 79 grams. The model was sized to a wingspan of 60 inches and at 340 square inches it weighed 19 ounces.

The “Classic Flyer” is electrically powered with a brushless AXI 22 12/20 motor and Kokam lithium-polymer battery allowing for a total flight endurance of just over 25 minutes. The motor/propeller combination used allows for enough excess power such that more advanced maneuvers are possible for the capable pilot.

1 - Size, weight, and power of the motor must fit the airplane. Research is required to get it right. 2 - KV times battery voltage = RPM must be selected to fit the plane. You can't run a 10 inch prop on a Bixler without surgery and experimentation.

A good quality RC motor will have an efficiency of about 85%. Propeller efficiency varies widely, depending on size, pitch, air speed and revolution rate. The best efficiency is around 70% when the prop is operating at its “sweet spot” ratio of V/(n* D m ) , where n is the revolution rate and Dm is the propeller diameter.

A commonly recommended motor for hobbyist Quadrotor design is the TowerPro Brushless Outrunner 2410-09 (see Figure 9: TowerPro Brushless Outrunner 2410-09 (17)). This motor meets all the requirements of the Quadrotor design. It is a high torque motor with a Kv rating of 840 and a weight of only 64.5g.

The brushless mini motor efficiencies were taken from the manufacturer catalogue as such the overall efficiency of propeller-motor combinations was close to 56%. It is very prudent to measure thrust, torque and speed simultaneously of the propulsive system to obtain accurate efficiencies.
