User Manual

You can modify the settings of P-Gain, I-Gain and PWM frequency (with ProgCard II) but usually is
not necessary. Use only clean and tight gold connectors for motor and battery. The 3.5 mm PK
connectors have proven to be the best choice up to 100A. Pay attention for the battery connector
to choose a polarity safe system. Exchange low-friction or oxidized plugs and sockets. Because only
tight sitting contacts will ensure a high current ow, protect the speed controller against
dangerous voltage peaks and avoid disturbances.
Trouble shooting:
1 Beeps/ashes: Incorrect throttle curve for Gov.-Store Mode
2 Beeps/ashes: Under-voltage identication
3 Beeps/ashes: Temperature rise warning
5 Beeps/ashes: Receiver signals failed
6 Beeps/ashes: start up failed
Any error that happens during ight is signaled by the ESC after motor stop (ashing LED and
beeps).
In case the ESC reduces power completely because of low-voltage, critical
temperature, receiver signals lost or the startup failed, the error levels 2,3,5 and 6 will be stored
permanently (crash analysis). To reset these errors connect the ESC to the battery
with the stick at full power and/or with 100% throttle pre-selection (throttle curve), and disconnect
it after the interval beep. Please leave the stick at full power, while disconnecting, otherwise you
activate the RC-Setup. Alternatively the errors can be cleared by connecting the
ProgCard.
With an activated brake, the error is only signaled after a tension reset or in wind milling position.
Plane settings
The ESC has a xed throttle curve setting, so that with all usual transmitters the stop and full power
points are linearly connected. With all programmable transmitters, the throttle range should be set
to default (±100%), the center point set to zero and throttle trim enabled. Nevertheless, with some
transmitter types the range needs to be adjusted. For that the throttle endpoints have to
be set so that one notch before lowest stick position the motor is stopped and that one
notch before full power the motor is actually at full power. Full power is
indicated by the LED that is completely turned o.
If during spin up rpm variations (wowing or erratic sound) are experienced, the timing
must be increased. If no improvement can be obtained at 30°, then the
motor is overloaded. Here a smaller propeller, a one cell smaller battery or a
stronger motor will help. If after motor stop you hear 2 beeps repeating, it means that the battery
voltage
dropped down below the setting value. Eventually try a cuto voltage of
2.9 or 3.0V per cell. If there is still no improvement, then the battery is
discharged or too weak, the wires are too long or to small or a connector is out of order.
With an active brake you can hear these warning tones only in windmill position. This is the small
range on the throttle stick between brake and motor start. You can reach this position with 2
notches or with a high trim and a short gas start.
If no automatic timing is wished, it can be adjusted according to the following guideline.
Inrunner 0 to 12°
Outrunner 18 to 30°

- Programming with the ProgCard II or RC-Setup.
Initial setup:
Connect the Motor to the ESC to hear the beeps. After connecting the battery (red = plus, black =
minus) you hear 3 descending tones. Subsequently, follows a number of beeps according to the cell
number of the connected Lipo battery. In case the transmitter stick is in throttle o, you hear now
3 ascending tones. If you here the interval-beep disconnect the battery and reverse the servo-signal
in the transmitter.
Especially if you use a Futaba transmitter you have to reverse the servo-signal.
Note: Wrong Battery polarity leads to heavy damage and to the loss of warranty!!!
If the motor turns in the wrong direction, simply exchange 2 of the 3 motor wires.
Helicopter settings
For helicopters in governor mode, the full throttle range (100%) must be calibrated once.
For some transmitters, this range is indicated in the helicopter menu, throttle
curve 0...100% and some other transmitters -100...+100. Please refer the RC-Setup especially the
Basic Setup or ProgCard.
--- The ESC is ready for use. ---
On delivery all relevant heli parameters are set to default.
This default will t nearly all setups.
You don’t need to program further at a rst step.
Here a listing of the default settings.
- Timing 18°
- Brake o
- under voltage recognition adjusted to Lipo mode 3.1 V
- automatically cell count
- Act. Freew. on
- Governor Mode on
- P-Gain 0.9
- I-Gain 0.05
- Startup Speed = Heli middle
- PWM-Frequency 8 kHz
- Startup Power = Auto 1-32%
