4. When self-test is finished, a long “beep-----” tone should be emitted.
5. Slowly move the throttle stick up, the prop should start to rotate clockwise (looking from
the cockpit of the plane). If it spins in the opposite direction, pull the throttle stick back,
disconnect the flight battery and swap any two of the three cables between the motor and
the ESC. The re-check again.
PROTECTION FUNCTION
1. Start up failure protection:
If the motor fails to start within 2 seconds of throttle applica-
tion, the ESC will cut-off the output power. In this case, the throttle stick MUST be moved
to the bottom again to restart the motor. (Such a situation happens in the following cas-
es: The connection between ESC and motor is not reliable, the propeller or the motor is
blocked, the gearbox is damaged, etc.).
2. Over-heat protection:
When the temperature of the ESC is over about 110 Celsius de-
grees, the ESC will reduce the output power.
3. Throttle signal loss protection:
The ESC will reduce the output power if throttle signal is
lost for 1 second, further loss for 2 seconds will cause the output to be cut-off completely.
PROGRAMMABLE FUNCTIONS OF THE KAVAN ESC
1. Brake:
ON/
OFF
ON
- Sets the propeller to the brake position when the throttle stick is at the minimum posi-
tion (Recommended for folding props).
OFF
- Sets the propeller to freewheel when the throttle stick is at the minimum position.
2.Battery type: LiPo
or NiCd/NiMh
3. Low Voltage Cutoff Type: Reduce Power
/ Hard Cut-off
Reduce Power
– ESC reduces motor power when the preset Low Voltage Protection Thresh-
old value is reached.
Hard Cut-off
– ESC instantly cuts motor power off when the preset Low Voltage Protection
Threshold value is reached
4. Low Voltage Protection Threshold:
(Low
/
Medium
/ High)
1) For Li-xx packs
- the battery cell number is calculated automatically. Low / Middle / High
cutoff voltage for each cell is: 2.85V/3.15V/3.3V. For example: For a 3S Lipo, when “Middle”
cutoff threshold is set, the cut-off voltage will be: 3.15*3=9.45V.
2) For Ni-xx packs
- low / medium / high cutoff voltages are 0%/50%/65% of the startup volt-
age (i.e. the initial voltage of battery pack), and 0% means the low voltage cut-off function
is disabled. For example: For a 6 cells NiMH battery, fully charged voltage is 1.44*6=8.64V,
when “Middle” cut-off threshold is set, the cut-off voltage will be: 8.64*50%=4.32V.
5.Soft Acceleration Start up: Normal
/ Soft / Very Soft
Normal mode is suitable for fixed-wing aircraft. Soft or Very Soft modes are suitable for
helicopters. The initial acceleration of the Soft and Very Soft modes are slower, it takes 1.5
second for Soft startup or 3 seconds for Very Soft startup from initial throttle advance to full
throttle. If the throttle is completely closed (throttle stick moved to bottom position) and
opened again (throttle stick moved to top position) within 3 seconds after the first startup,
the re-startup will be temporarily changed to normal mode to get rid of the chance of a crash
caused by slow throttle response. This special design is suitable for aerobatic flight when
quick throttle response is needed.
6. Timing setup: Low
/ Middle / High
Low (3.75°)
– Setting for most 2 pole motors.
Middle (15°)
- setting for motors with 6 or more poles.
High (26.25°)
- setting for motors with 12 or more poles, outrunners
In most cases, middle or low timing works well for all types of motors. However for high
efficiency we recommend the Low timing setting for 2 pole motors (generally, in-runners)
and middle timing for 6 poles and above (generally all outrunners). For higher speed, High
timing can be set. Some motors require different timing setups therefore we suggest you to
follow the manufacturer recommended setup.
Note:
Run your motor on the ground first after making any changes to your motor timing!
USING THE KAVAN PROGRAMMING CARD (OPTIONAL)
You can also use the optional KAVAN programming card to program your desired function.
The use of the KAVAN card is very simple and convenient: the programmable function and
their values are to be set with a couple of buttons. Simply set all the functions on the card to
the valuess corresponding to the desired values and load the settings to the ESC. Program-
ming your ESC with the KAVAN Card is a breeze!

Trouble
Possible Reason
Solution
After power on, motor does not
work, no sound is emitted.
The connection between
battery pack and ESC is
not correct
Check the power connec-
tion. Replace the connec-
tor.
After power on, motor does not
work, such an alert tone is emitted:
“beep-beep-, beep-beep-,beep-
beep-” (Every “beep-beep-” has a
time interval of about 1 second).
Input voltage is abnor-
mal, too high or too low.
Check the voltage of bat-
tery pack.
After power on, motor does not
work, such an alert tone is emit-
ted: “beep-, beep-, beep- ”(Every
“beep-” has a time interval of
about 2 seconds).
Throttle signal is irregu-
lar.
Check the receiver and
transmitter. Check the ca-
ble of throttle channel.
After power on, motor does not
work, such an alert tone is emit-
ted: “beep-, beep-, beep-” (Every
“beep-” has a time interval of
about 0.25 second).
The throttle stick is not
in the bottom (lowest)
position.
Move the throttle stick to
bottom position
After power on, motor does not
work, a special tone “
56712” is
emitted after 2 beep tone (beep-
beep-).
Direction of the throttle
channel is reversed, so
the ESC has entered the
program mode.
Set the direction of throttle
channel correctly.
The motor runs in the opposite
direction.
The connection between
ESC and the motor need
to be changed.
Swap any two wire con-
nections between ESC and
motor.
TROUBLESHOOTING
SAFETY PRECAUTIONS
• Do not install the propeller (fixed wing) or drive pinion (helicopter) on the motor when you
test the ESC and motor for the first time to verify the correct settings on your radio. Only
install your propeller (plane) or pinion (heli) after you have confirmed that the settings on
your radio is correct.
• Never use ruptured or punctured battery cells.
• Never use battery packs that are known to overheat.
• Never short circuit battery or motor terminals.
• Always use proper insulation material for cable insulation.
• Always use proper cable connectors.
• Do not exceed the number of cells or servos specified for the ESC.
• Wrong battery polarity will damage the ESC and void the warranty.
• Install the ESC in a suitable location with adequate ventilation for cooling. This ESC has a
built-in over temperature cutoff protection feature that will immediately cut power to the
motor once the ESC temperature exceeds the 230° F/ 110° C temperature limit.
• Use only batteries that are supported by the ESC and ensure the correct polarity before
connecting.
• Switch your transmitter ON first and ensure the throttle stick is in the minimum position
before connecting the battery pack.
• Never switch your transmitter OFF while the battery is connected to your ESC.
• Only connect your battery pack just before flying and do not leave your battery pack con-
nected after flying.
• Handle your model with extreme care once the battery pack is connected and keep away
from the propeller at all times. Never stand in-line or directly in front of any rotating parts.
• Do not immerse the ESC under water, do not allow it to get wet while powered up.
• Always fly at a designated flying site and follow the rules and guidelines set by your model-
ler’s club.
