Initial setup:
After connecting the battery 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 off, you hear now 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 YGE is ready for use. ---
If the motor turns in the wrong direction, exchange simply
2 of the 3 motor wires.
The entire wire length, from the controller to the battery,
may not exceed 15cm. If longer wires are necessary, a
Low ESR switching capacitor of 330ìF/25V should be
soldered between plus and minus wires every 20cm.
likewise the motor wires can be extended. Then please
twist the 3 lines, in order to minimize interference
emission.
Note: Inverting the Battery polarity leads to heavy
damage and to the loss of warranty!!!
General Settings:
The speed controller has a fixed 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
off.
On delivery the Timing is adjusted to 18°, brake is
switched on middle, and the under voltage recognition
adjusted to Lipo mode 3.0 V.
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 cutoff voltage of 2.9V 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.
Innrunner 0 to 12°
Outrunner 18 to 30°
If your motor manufacturer indicates a timing
recommendation, it is of course preferable to use it.
Basic rule: the higher the timing the higher the full power
rpm.
The easiest to make these changes is the ProgCard II.
There is also the possibility to perform the setup with the
transmitter; however it will not be explained here. You will
find it in the RC-setup manual under www.yge.de in the
Download area.
