Choosing a power system:
Power system can be chosen based on the type of flying expected of the model and all up weight of the aircraft. Sedate flying
from a hand launch requires 35 watts per pound(W/Lb). Taking off the ground needs approximately 50W/Lb. Aerobatics and
good climb performance, 75W/Lb. Anything more than 75W/Lb will result in excellent performance. Based on the weight of
the model and the flying desired, the power require can be calculated. Select the voltage of the battery being used. It is best
to use a loaded voltage of about 90% of nominal. Now, calculate the current required. From the chart, pick a motor at the
voltage you intend to use and find the prop that pull the required current.
Maintenance:
Brushless motors are almost maintenance free, so minimal care is required for long life. Keep the motor clean free of dust
and dirt, especially the bearings. Dirty bearings wear quickly. Lubricate the bearings regularly with light oil. Do not immerse
the motor in water, or solvents. Do not bend the wires excessively and secure wires to prevent breakage due to fatigue from
vibration. Always used balanced propellers to reduce loads on bearings, to reduce noise, and reduce stress on the airframe.
Be careful to install pinion gears properly. Improperly installed press fit pinion gears can result in damaged bearings, bent
or broken shafts, or broken rotor assemblies. If in doubt, use set screw secured or glue-on type gears to prevent damage.
