Specifications
If you strip a plastic screw or setscrew hole, then you can fix it by squirting a small bit of CA in-
to the screw hole and letting it dry to give the screw additional friction. But, it's better not to
strip it in the first place.
10.1.6. Breaking-in motors
If you are using a brushed motor with carbon brushes, then you should "break-in" the motor
before your first flight. This break-in procedure allow maximum contact of the brushes with the
commutator. This will allow the motor to run at maximum efficiency and extend motor life.
Break-in is not required for these motor type:
• Metal brushed motors. This includes motors such as the Team Orion Elite Micro Modified
motor.
• Micro heli tail motors. This includes both the gray and black endbell GWS IPS-style motors,
and the N20 style motors.
• Brushless motors. Brushless motors do not have brushes and therefore require no break-
in.
There are at least two ways to do this:
• Dry method: Run the motor for two hours at 1/4 throttle.
• Wet method: Run the motor for 10-15 minutes in a glass of water.
Be sure to disassemble the motor afterwards and throughly dry everything, otherwise parts
may rust. Don't use this method on motors which are assembled using bent metal tabs (such
as the Piccolo motors) because the metal tab may break off when disassembling or reas-
sembling the motor.
Be careful with the carbon dust. It can get into your lungs and cause severe breathing difficulty,
especially if you're asthmatic.
Be sure to blow the carbon dust out OUTSIDE with some compressed air and don't get the
carbon dust into your lungs.
10.1.7. Carbon dust
Beware of carbon fiber dust. It is classified as a hazardous material and can cause severe
breathing difficulty, especially if you are asthmatic.
Warning
DO NOT CUT CARBON FIBER INDOORS. ALWAYS CUT CARBON FIBER OUT-
SIDE.
10.1.8. Capacitors
If you are using a brushed motor, be sure to solder three capacitors to the motor: one between
the positive terminal and negative terminal, one between the postive terminal and case, and
one between the negative terminal and case. This will reduce the amount of interference gen-
