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. Se-
date flying from a hand launch requires 35 watts per pound(W/
Lb). Taking off the ground needs approximately 50W/Lb. Aero-
batics 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 mini-
mal 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 dam-
aged bearings, bent or broken shafts, or broken rotor as-
semblies. If in doubt, use set screw secured or glue-on type
gears to prevent damage.
