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 handlaunch requires 35 watts per pound(W/Lb). Taking off the ground needs approximately 50W/Lb. Aerobatics and
good climb performance, 75W/Lb. A power loading in excess of 75W/Lb will result in excellent performance. Based on the
weight of the model and the flying desired, the power require can be calculated. The choose the votlage of the battery being
used. It is best to use a loaded voltage of about 90% of nominal. Then calculate the current required. From the chart, pick a
motor at the intended voltage and find the prop that draws the required current.
Maintenance:
Brushless motors are almost maintenance free, so minimal care is required for long life. Keep the motor free of dust and dirt.
Pay special attention to the bearings, as 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.
