Safety instructions
The guarantee is rendered invalid when damage occurs as a result of
non-compliance with the operating instructions! We do not assume
any liability for any damage arising as a consequence!
We do not assume any liability for material and personal damage
caused by improper use or non-compliance with the safety instruc-
tions. The warranty is voided in these cases.
• The unauthorized conversion and/or modification of the product is inadmissible
because of safety and approval reasons (CE).
Never disassemble the regulator, there are no components inside the housing that need
to be set or serviced by you.
Furthermore, the guarantee/warranty would also expire in such a case!
• Do not carelessly leave the packaging material lying around since this may become
a dangerous toy for children.
• The product is not a toy and should be kept out of the reach of children.
• When dealing with vehicles, rechargeable batteries, cruise controls and electric motors,
make sure that there are never any parts of the body or objects in the rotating parts.
• Never exceed the technical limits of the regulator (e.g. continuous current).
• Only operate the regulator with rechargeable batteries, never via a plug-in power
supply.
• Make sure that the device is connected correctly; or the regulator and the connec-
ted device are damaged. There is furthermore a danger of fire and explosion!
• Only connect one single brushless motor to the regulator.
• The regulator is not suitable for the operation of normal electric motors with two con-
nections. Only a brushless motor suitable for that is to be connected and operated
with the regulator.
• When installing keep the highest possible distance between receiver and regulator
in order to avoid an interference. The same applies for the distance between regu-
lator and motor.
• Do not lay the aerial line of the receiver parallel to conducting cables.
• Only switch on your electronic model when you have made sure that the transmitter
is in operation and the transmitter stick for the motor regulation (throttle control) is in
the lowest position (the regulator has no „reverse gear".
• When finishing the operation, the rechargeable battery of the regulator is to be
disconnected first. Then switch the transmitter off.
• Always carry out a transmission check when the motor is running, too.
• There must be sufficient cooling for the regulator and also the motor when opera-
ting the model. Do not cover the cooling element of the regulator; do not use the coo-
ling element for fixing, e.g. with an adhesive tape.
• Protect the regulator from dirt and dampness. The regulator is neither waterproof
nor watertight!
• Regularly check the regulator and the cables connected to the plug-in connector for
damage. If the regulator is damaged, do not use it any longer.
• Before recharging the rechargeable battery it has to be disconnected from the regu-
lator.
• Do not impede the motor, do not hold it on and do not block it.
• Keep metallic objects away from the sold contacts of the connection cable of the
regulator, risk of fire/short circuit, furthermore the rechargeable battery can explode!
o
• The condenser at the short cable outside the casing cannot be taken off; do not
damage it.
Installation and connection
°
• You should not shorten the motor cables and rechargeable battery cables of the
regulator, because it can be difficult to tin the cables again.
• Connect the three motor cables with the brushless electronic motor. When the direc-
tion of rotation should be reversed later on, two of the three cables are to be inter-
changed.
• The regulator is delivered with so-called „open" cable ends for the rechargeable bat-
tery connection. Depending on what regulator system is used on the flight battery,
a suitable connector plug has to be attached.
Always keep an eye the correct polarity when mounting the plug, otherwise the
regulator is destroyed. The polarity of the rechargeable battery cables is colour-
coded: Red = plus (+); black = minus (-).
• Connect the regulator to the receiver output for the motor regulation (make sure to
arrange correctly!).
• Install the regulator as far away as possible from the receiver and aerial cable. Make
sure that no cables can get into movable parts (e.g. servos, servo rods, drive axles,
etc.). Fix the regulator and the cable in your model.
Secure the electric motor as well as the entire model so that it cannot shift or move
freely when the motor is at full speed or vibrating. Make sure that moving parts can
rotate freely. Keep hands and other body parts away from the drive, do not reach into
movable parts, risk of injury!
Please note:
The BEC system built into the regulator supplies the connected receiver and all servos
with the necessary voltage/current (+5V=, 1A max.) directly from the rechargeable
battery. You will have to use a separate receiver battery in the case of higher current
consumption of your servo. Then the red cable has to be removed from the 3-pin regu-
lator plug of the control system, secure it with insulation tape. The simultaneous ope-
ration of receiver battery and BEC system is not permitted!
During motor operation, the voltage of the rechargeable battery is continuously moni-
tored by the regulator. If the voltage value should sink under a certain value, the
power output is reduced (function can be switched off).
The regulator comprises an integrated voltage monitoring. That is why
the used rechargeable battery type has to be programmed on the regu-
lator (possible is: NiCd/NiMH, 2 LiPo cells, 3LiPo cells).
When there is undervoltage the regulator allows a performance
reduction (for model helicopters recommended) as well as switching
off the motor, in order to protect the accumulator.
Therefore, the regulator rechargeable battery type always has to be
programmed first before using the regulator (the setting is kept also
after having switched off/disconnected the rechargeable battery).
Otherwise it can (especially for LiPo rechargeable batteries) damage
the rechargeable batteries when it comes to a total discharge!
Programming
The regulator allows you to program different programming. The current motor status
is indicated by the beeps („_" = deep beep, „-" = high beep, „
Switch break on/off
1. Switch on the transmitter (do not connect the rechargeable battery with the regu-
lator yet!).
2. Move the throttle lever into the full throttle position.
3. Now connect the rechargeable battery with the regulator.
4. The motor beeps several times after 5 seconds („_ _ - -"). The programming mode
is activated.
5. If you now move the throttle into the lowest position, the brake is switched (on/off).
The motor beeps once for confirmation (brake turned on) or twice (brake turned
off).
6. The programming mode is left, the regulator is in the normal operating mode.
Other programming:
1. Switch on the transmitter (do not connect the rechargeable battery with the regu-
lator yet!).
2. Move the throttle lever into the full throttle position.
3. Now connect the rechargeable battery with the regulator.
4. The motor beeps several times after 5 seconds („_ _ - -").
The programming mode is activated.
5. The motor now makes different beeping signals one after the other (each time 5x).
The symbols stand for the following beep signals:

If the throttle is pushed from the full throttle position into the opposite direc-
tion while the motor is beeping, (move throttle downward entirely, since the
regulator has no reverse gear!), the regulator adopts the respective setting
and then always leaves the setting mode automatically.
The tone sequence/beeps is always 5 times so that you have enough time to bring
the throttle from full throttle into the opposite direction.
For programming another function the programming mode must be activa-
ted again, see above. Then wait again until the motor beeps for the functions
you want to program.
The settings remain even when the regulator was disconnected from the rechar-
geable battery.
Operation
•
" = short beep):
First program as described above.
The type of rechargeable battery is very important for an initial operation
so that the regulator can reduce the speed for undervoltage, in order to
avoid a total discharge and not damage the rechargeable battery.
If you notice that the regulator has reduced the speed while for example
flying a helicopter, you should land immediately.
Turn-on procedure:
1. Switch on the transmitter (do not connect the rechargeable battery with the regu-
lator yet!).
2. Move the throttle into the lowest position (the regulator does not have a reverse).
3. Now connect the rechargeable battery with the regulator.
4. After a short time the motor should either beep once (activating the brake) or beep
twice (brake turned off).
If there is no beep, the throttle is not in the neutral position (for exam-
ple adjusted trimmer or similar).
For safety reasons, the motor is not activated, the regulator does not
work.
First bring the throttle into the lowest possible position, correct the trimmer
if necessary.
Only when there are now one or two beeping sounds, the regulator will
have recognized the neutral position and is ready for operation.
5. The regulator is now ready for operation and reacts to the remote control.
Turn-off procedure:
1. Stop flying the model.
2. Unplug the rechargeable battery from the regulator.
3. Switch off the transmitter.
