1. Power Module Set - For VMA-D210X DO27 - Operating
 
 
Consult any labels carefully, particularly the larger WARNING labels. The labels are largely self explanatory. Paying attention to the operating limits will help prevent damage to your equipment.
 
We developed this Power Module as a "system" suitable for your model. We strongly advise against changing any component within this system. If a component requires replacement, ensure you replace it with a new but identical component to that which is being swapped out.
 
 
1.1. Propellers - Power Module Operations - VMA-D210X DO27
 
a) See the Warning label on the firewall. Do NOT exceed the maximum propeller size noted.
 
b) With power disconnected, double check the propeller to make sure it is not damaged or nicked in any way and that it is securely and safely mounted. Check before and after each flight.
 
c) Ensure the propeller turns true (no wobble) and that it is balanced and that all propeller fasteners are tight. 
 
USING THE WRONG PROPELLER &/or OPERATING WITH EXCESSIVE VIBRATION WILL DESTROY THE MOTOR.
 
d) Ensure that your propeller is rotating clockwise when viewed from behind (looking forward as if you were in the cockpit) and that the prop is blowing air from the front of the model to the back.
 
f) If the propeller is rotating clockwise when viewed from behind but air is flowing from the back to the front of the model, the propeller is mounted on the motor backwards. Check and reinstall the propeller correctly. In general the brand logo and other writing on propellers should face forwards.
 
g) If the propeller is rotating backwards, reverse the black and white wire connections between the motor and the electronic speed control.
 
1.2. On the Ground - Power Module Operations - For VMA-D210X DO27
Operating the brushless motor on the ground or in a static mode whereby the aircraft cannot move, puts peak loads on the motor while not providing adequate cooling normally generated in flight. Peak loads coupled with inadequate air flow leads to very rapid heat buildup within the brushless motor that can damage or destroy the motor very quickly.
 
ENSURE ADEQUATE COOLING. DO NOT OPERATE AT HIGH THROTTLE ON THE GROUND FOR LONGER THAN 10 SECONDS.
1.3. Powering Up - Power Module Operations - VMA-D210X DO27
 
a) Move your throttle stick all the way down to 0 (no power).
 
b) Turn on your transmitter
 
c) Turn on your receiver.
 
d) Ensure the model is held securely in order to test the motor system. Tie it down or hold the fuselage at the back.
 
STAY WELL CLEAR OF THE PROPELLER AND PLUG IN YOUR BATTERY.
 
e) Advance the throttle on your transmitter
 
f) The Electronic Speed Control (ESC) will apply power to the motor and the prop will begin to rotate. Very briefly advance the power to full throttle to ensure the motor spools up to full power. Do this for no more than 2-3 seconds at a time.
 
g) If the ESC beeps rather than makes the motor turn it is because the ESC is being powered up with the throttle stick at a non-zero position. This is a safety feature to prevent rotation of the prop unless you begin from a zero throttle position after each power up.
 
1.4. Motor Power Auto-Cutoff - Power Module Operations - VMA-D210X DO27
The Electronic Speed Control (ESC) has an embedded "auto-cutoff" controller that will reduce battery power supplied to the motor as the battery reserve begins to run out. This auto-cutoff controller ensures that the battery retains sufficient energy to power the receiver and servos. As the energy reserve in the battery approaches "empty", the auto-cutoff begin to reduce power available for the motor while allocating the remaining energy to provide power for the receiver and servos so that you can maintain flight control using the remaining energy.
 
Land immediately when you detect that the motor power is beginning to fade. Once the power begins to fade, you have a very short time remaining before the ESC will auto-cutoff power to the motor.
