- Anti sparkling circuit: reduces connection sparkles.
- Mode - Programming
Mode 2:
The controller is programmed for governor use. You do not
have to program anything else. The throttle end points are
set to 1.1 ... 1.9ms. This throttle curve will then correspond
to 0 to 100% with the transmitter.
If you want to fly different rpms and switch them in flight, you
have to start the model with the highest rpm.
Mode 3:
In Gov-Store you have to switch once to the highest possible
rpm (e.g. 90%) in order to learn in the motor parameters.
Thereafter you can start with the lowest rpm and switch in
flight if you want.
The Gov function starts from 50% of the throttle opening.
That is why we do not recommend to operate the heli under
50%.
Information to mode 1...3
We recommend the following throttle openings:
Hover (Low RPM) 55 ... 60%
Standard
70%
3D
80 ... 85%
In case rotation is too high with the recommended throttle
openings, you should choose a lower pinion or a motor with
less kv.
Initial setup:
Connect the master J/R cable to the receiver throttle channel
or FBL System and the red/brown Slave into an empty slot
or using an Y-link parallel to a servo output. If you want to
use the Vbar governor, connect the orange Slave to the Vbar
sensor input.
Once you have connected the battery (red = positiv, black =
neg.), you will hear 3 descending beeps. Thereafter you will
hear a number of beeps according to the cell number of the
connected Lipo battery. In case the transmitter stick is in the
throttle off position, you will now hear 3 ascending tones.
You need to connect the motor to hear the beeps, as it is the
motor itself which acts as a speaker.
--- The ESC is ready to use. ---
If the motor turns in the wrong direction, exchange simply 2
of the 3 motor wires.
Use only clean and tight gold connectors for motor and
battery. Pay attention to the battery connector and choose a
safe polarity system. Exchange low-friction or oxidized
plugs and sockets. Because only tight sitting contacts will
ensure a high current flow, protect the speed controller
against dangerous voltage peaks and avoid disturbances.
With all ESC types, the entire wire length, from the
controller to the battery, may not exceed 25cm. If longer
wires are necessary, a low ESR switching capacitor of
330µF/25V should be soldered between plus and minus
wires every 20cm. You might also consider using our
capacitor module YGE Cap´s typ 5. Likewise the motor
wires can be extended. Then please twist the 3 lines to
minimize interference emission.
Note: Inverting the battery polarity leads to heavy
damage and to the loss of warranty!!!
Mode Programming:
1. For safety reasons remove ALL rotor blades!
2. Switch on TX and move the throttle stick to maximum.
3. Connect the battery to the ESC
