Caution: this controller is not protected against reversed polarity. Connecting a battery to the
controller's terminals with reversed polarity will instantly ruin the unit.
If you prefer to use a separate receiver battery instead of the BEC system, you must
withdraw the red wire from the receiver lead attached to the controller, and insulate
the bare ends to avoid short-circuits.
VERY IMPORTANT: since different transmitters feature different throttle settings, we strongly advise you to
use the „Throttle range set-up function" to calibrate the throttle range.
Setting the full-throttle and stop positions:
(if the transmitter is new, the throttle range should always be calibrated)
Switch transmitter on, move throttle stick to full-throttle position.
Connect battery to speed controller.
You will hear the special beep sequence „123". This means that the battery voltage is in the green zone.
This is followed by two fairly long beeps which confirm that the controller has correctly read in the upper limit
of the throttle range.
The throttle stick must now be moved to the appropriate Stop position within two seconds. The controller
confirms this with a fairly long beep.
This calibration procedure is concluded with the audible signal which indicates the brake setting (1 x short
beep = brake off; 2 x short beep = brake on).
The speed controller is now ready for use.
Brake setting:
Switch transmitter on, move throttle stick to full-throttle position.
Connect battery to speed controller.
You will now hear two fairly long beeps indicating the full-throttle position.
After about two seconds the controller emits one brief beep to indicate the „Brake off" setting.
After a further two seconds you will hear two brief beeps indicating „Brake on".
If you wish to set „Brake off", you must move the throttle stick to the zero position after the first brief beep.
If you wish to activate the brake, wait until you hear the second series of beeps before moving the stick.
To confirm the brake setting you will now hear a single fairly long beep followed by your selected setting (1
or 2 brief beeps).
The speed controller is now ready for use.
NOTE:
If you do not move the throttle stick during the set-up phase, the motor will then not run. In this case you must
repeat the procedure.
Using the controller for the first time:
- Move the throttle stick to the Stop position, then switch the transmitter on.

Connect the flight battery to the speed controller: you will hear the special sound sequence „123", followed by
a fairly long beep and the selected brake setting.
The speed controller is now ready for use.
Protective functions
1. Start-up guard: if the motor does not start within two seconds of the throttle command, the speed controller
switches off the output voltage. If this should happen, you MUST move the throttle stick fully back in order
to start the motor. Failure to start may have the following reasons: the connection between speed controller
and motor is intermittent, the propeller or motor is jammed, the gearbox is damaged, etc.
2. Overheating guard: if the controller's temperature rises above 110°C, the unit reduces the output voltage.
3. Throttle signal failure guard: if the throttle signal is absent for one second, the controller reduces the output
voltage. If a further failure occurs for two seconds, the controller switches off the output voltage completely.
