Direction of Rotation and Motor Timing:
To change the direction of rotation, simply switch over the connection of the outer two cables
between the motor and speed controller, but leave the centre cable connection untouched.
The optimum motor timing is set by the speed controller, however, some high-end
programmable speed controllers allow for some adjustment of the motor timing.
Running-in:
There are no brushes or other moving parts to bed in, so no running-in is required.
Cooling:
Please note that your AXI is a high performance electric motor working under high current
loading which produces some heat. Proper cooling is essential in just that same way as it is
with an internal combustion engine. Overheating of your motor causes increased wear in the
bearings and partial demagnetisation, which decreases performance of the motor. As with all
types of magnetic material, complete demagnetisation of the neodymium magnets can occur
at over 130 C.
Please make sure that cooling air can flow through the holes in the front plate to allow cooling
of the armature and magnets. There is a simple rule of thumb: the area of cooling air intake(s)
on your model should be at least twice the total area of openings on your motor. The area of
cooling outlet(s) should be larger than the intakes to allow for expansion of the heated air.
Care and Maintenance:
Avoid running your motor under dusty or wet conditions. Avoid foreign matter getting in the
cooling holes of your motor. Beware of small bolts, screws and other small items that can be
attracted to the magnets of your motor during installation or maintenance. Do not disassemble
motor. The bearings of this motor are lubricated using special high quality grease that will last
through the whole expected life. Do not use any organic solvents, cleaners or detergents to
clean your motor, these agents may wash out the grease and substantially decrease the
lifetime of your motor. If there is some dirt in your motor (after an accident) do not try to rotate
the shaft. Carefully remove the dirt with compressed air at first. In the case of more serious
damage the motor should be sent for service. Never try to straighten a bent shaft, if the large
diameter hardened steel shaft becomes bent there will be more serious damage inside the
motor. If you are in doubt, please contact the manufacturer to get qualified assistance or
repair. Avoid unnecessary dismantling of your motor.
Safety Notes:
Install only undamaged and balanced propellers and securely tighten with a wrench. Never
touch, or allow any object to come into contact with the rotating propeller. A weakened or
loose propeller may disintegrate or be thrown off which could result in serious injury. Inspect
the propeller after each flight. Discard any propeller that has nicks, scratches or any other
visible defect. Discard the propeller after a crash or contact with ground during a heavy
landing even if the propeller looks undamaged, there could be internal stress or damage
resulting in a failure later. For their safety, keep all onlookers (especially small children) well
away (at least 20 feet or 6 metres) when preparing your model for flight. Keep the propeller
pointing away from you and other people, and walk well clear of spectators. First switch on
your transmitter, check the position of the throttle stick (and related switches if any), only then
connect your power pack to the speed controller and switch on the receiver. Always leave
space for the propeller to rotate (in case of a speed controller failure or interference).
A stopped propeller could result in damage to your controller and motor, or even cause fire.
