USER MANUAL
RO-CONTROL PRO WIFI ESC
RO-CONTROL PRO WIFI 2-6S 80 A HV-BEC Nr.: 8730
RO-CONTROL PRO WIFI 2-6S 100 A HV-BEC Nr.: 8731
RO-CONTROL PRO WIFI 2-6S 130 A HV-BEC Nr.: 8732
06. SAFETY PRECAUTIONS
Start-up protection
ESC will cut off output if it fails to start the motor within 3 seconds by accele-
rating throttle. you need to move the throttle stick back to the bottom
position and restart the motor.( The possible causes : Bad connection or dis-
connection between ESC & motor , propellers are blocked, etc)
Over temp protection
When ESC temperature is higher than 100 °C,it will reduce output power
(throttle will be limited below 40%) for protection, leave some power for mo-
tor to land , when the temperature Reduced to 80°C , ESC recover to normal
running mode.
Signal loss protection
When ESC detects the loss of throttle signal for over 1 seconds, it will cut off
power or output immediately to avoid an even greater loss caused by the
continuous high speed rotation of propellers. ESC will resume the correspon-
ding output after the normal signal is restored.
Alarm tone: (To judge the abnormal cases via alarm tone)
1. 1. Alarm tone of signal loss: when ESC detects no signal, motor will emit the alarm tone “Beep-,Beep,-
Beep-” (alarm tone emits every 2 seconds).
2. 2. Alarm tone of throttle not in the zero throttle position: throttle not in the zero throttle position, motor
will emit “Beep-Beep-Beep-Beep-Beep-” (urgent single short tone).
3. 3. Alert tone of narrower throttle range: when throttle range is set too narrow, motor emits “Beep-
Beep-Beep”(harried alarm tone emits last for 2 seconds). You must calibrate throttle range again.
07. RUNNING THE ESC FOR THE FIRST TIME
1.
If you are using the ESC for the first time, you must adjust the throttle range. You only need to cali
-
brate the throttle range once, but you must reset it when you change the transmitter.
2. Before connecting the battery, check that all connectors are correctly polarized to prevent damage
from incorrect connection or shorting.
3.
If the motor suddenly stops during flight, move the throttle to the zero position immediately. Then push
the throttle forward again to restart the engine. Just slow down a little and land the plane immedia-
tely to check everything carefully.
08. TROUBLE SHOOTING
Problem
possible reason
Solution
After switching on, the motor
does not start, no tones are
emitted.
Poor connection between
ESC and battery.
Check connections and polarity
bad solder joints, bad
contact
Resolder connections
Low input voltage
Check battery, use fully charged battery
ESC might have a problem
Change ESC
After switching on, the motor
emits tones for the number of
cells, but it does not start.
Throttle stick not calibrated Recalibrate throttle stick
After switching on, the ESC
works, but the motor does
not start and does not emit a
sound.
After switching on the ESC,
the motor does not start and
emits the warning tone „Beep-
Beep“ (short stop after „Beep-
Beep“).
Poor connection between
ESC and battery or bad
solder joints
Check connections, resolder connec-
tions
Defective
Change motor
Wrong battery voltage
Check battery and number of cells in
settings
After switching on, the motor
does not run, it emits the war-
ning tone „Beep-, Beep-, Beep
-“ (sounds every 2 seconds).
No signal from receiver
Check the connection to the receiver.
Check the transmitter and receiver and
make sure the signals are present.
After switching on the motor
does not run, a continuous
warning tone „Beep-“ sounds.
Throttle stick not in lower
position
Put the throttle stick in lower position or
racalibrate the throttle stick
The motor does not run after
switching on. It emits 2 long
beeps and 2 short beeps.
The positive and negative
values of the throttle chan-
nel are reversed. The ESC is
in programming mode.
Adjust the throttle channel correctly, see
the transmitter manual.
The motor rotates in the wrong
direction.
Incorrect sequence of con-
nection cables between
motor and controller
1.Replace 2 of the 3 connecting cables
between the controller and the motor.
2. change the direction of motor rotation
via smartphone APP or transmitter.
The motor stops during ope-
ration.
The battery voltage is lower
than the undervoltage
protection threshold and
the protection mode is swit-
ched off.
1.Set the correct undervoltage protec-
tion threshold, fly with a full battery, se
-
lect power reduction, land immediately.
2.Make sure that your aircraft is within
the range that you can control with your
transmitter.
3.Pay attention to the voltage of the
transmitter battery, if it becomes empty,
please land immediately.
No input signal from recei-
ver
1.Check that the transmitter is working
correctly.
2. check that the transmitter and recei-
ver are connected.
3. strong interference in the environment.
Turn the unit off and on again to deter-
mine if it is working again. If the problem
still occurs, change the airfield.
Bad connection
Check the connections of battery and
motor
