Connections:
The speed controller can be connected to motor by direct soldering or with high quality connectors. Always use
new connectors, which should be soldered carefully to the cables and insulated with Heat Shrink Tubing. It is
possible to extend the cables to the motor battery pack up to a maximum of 8 inches. Deans Ultra or other high
quality connectors are recommended for connecting the motor battery pack to the controller.
zSolder controller to the motor wires
zSolder appropriate connectors to the Battery wires
zInsulate all Solder connections with Heat Shrink Tubing
zPlug the 3 Pin connector into the receiver throttle channel
InstallingtheController:
Install the speed controller in the model so that it is isolated from vibration and shock, using Velcro or double
sided foam tape. Allow space around it for cooling. Make sure that there is sufficient cooling of the motor and speed
controller by ducting air through adequate cooling holes from the outside airflow. Main power packs should be
connected at one attempt.
zLocate the controller toAvoid multiple touches of the connectors when installing a fresh motor battery pack.
Usingthecontroller:

zSwitch “ON” the transmitter and check the throttle channel settings are +/-100% (for computer radios). For
Radios program the “Servo Reverse” function on the throttle channel. Set the throttle to “closed” or brake
position
zConnect with battery. For speed controllers without BEC, switch on the power to receiver.
zYou should hear a ‘beep’. Between connect with battery and the ‘beep’ the throttle stick must not be
moved. If you do not hear a ‘beep’, disconnect the power connectors, wait for 5 seconds and repeat the
procedure of connecting.
zIf you do not hear ‘beep’ again, check the following:
1).Is 3 Pin connector plugged in throttle channel?
2).Is the throttle stick in “closed” position (OFF)?
3).Is the throttle channel in ‘normal’ position?
zThe position of ‘full throttle’ will be adjusted automatically.
zWarning: Once the Motor Battery Pack is connected, handle the model with extreme care! Ensure that
everyone is well clear of the propeller at all times. Rotating propellers are extremely dangerous!
zAlways Connect the motor battery pack just before flight and disconnect it immediately after landing the model.
zWarning: Even when the switch on the transmitter is ‘off’ remember the Motor Battery pack may be connected,
handle the model with extreme care and stay well clear of the Propeller!
Setting the Propeller Brake On or Off:
zThe speed controller is supplied with the ‘brake’ activated. If you want to turn off the brake, do the following:
1).Switch on the transmitter and move the stick to full throttle
2).Connect the main power pack
3).Wait 5 seconds
4).After 5seconds you will hear 5 single “beeps”
5).Swiftly move the throttle stick to the closed position; you will hear two “beeps”.
6).The brake is now turned off
zThe brake setting will not change after disconnecting the main power pack. When turning on the speed
controller with the brake active, you will always hear one ‘beep’. When the brake is turned off you will hear two
‘beeps’. If you want to activate the brake again, repeat the procedure.
Setting the Timing Mode:
zIt is possible to set two timing modes with these speed controllers
1).Soft timing-for 2,4,6, pole motors. Soft timing gives maximum efficiency
2).Hard timing only for 6 and more pole motors
zHard timing in creases both the motor revolutions and the current (up to 20%) with the same prop and battery
pack when compared to soft timing. This is more suitable for faster flying models.
zAlways use soft timing for first flights. If the temperature of the batteries, speed controller and motor are below
50℃degrees following the first flights it is possible to test the system using the hard timing mode. Do not use
hard timing with 2 pole motors.
zThe Speed controllers are supplied with soft timing-to change the timing:
1).Switch on the transmitter and move the stick to full throttle
2).Connect the main power pack and wait 5 seconds.
3).After 5 seconds you will hear 4 “beeps”
4).After further 5 seconds you will hear 5 “beeps” for soft timing

5).OR 5 double “beeps” for hard timing
6).The required timing is set by moving the throttle stick to the closed throttle position
7).The new timing is confirmed by a single “beep”(brake on) or a double “beep”(brake off)
zThe timing setting will not change after disconnecting the main power pack.
NotesAboutOperation:
zReversing the motor directions is achieved by the exchanging the position of any two wires connected to motor.
zThese controllers have automatic turn-off with auto detection for the number and type of cells.
zThe speed controller will turn-off the motor when the main power pack voltage falls under “Ni-XX: 5.3V or
reaches 0.7V/cell” or “Li-XX: 6.0V or reaches 3.0V/cell”. It depends on which occurs first.
zTemperature overload protection is built into the speed controller which turns of the motor when the
temperature reaches 100℃.
zThese speed controllers are equipped with protection functions that take care of correct start and operation of
the motor across the whole range of RPM, Current and Voltage.
zDo not connect the speed controller to just ‘any’ kind of power source. Take care to ensure the right polarity of
Ni-XX or Li-XX power packs only. Your speed controller will be severely damaged if it is connect to a battery
using the wrong polarity.
