Hornet Airplane ESC User Manual V3.
Thank you for purchasing HTIRC Hornet Brushless Electronic Speed Controller(ESC). Please read and pay
carefully attention to the following instructions before you start to work with all the related power devices
and the controller. We have no control over the use, installation, application, or maintenance of our
products, therefore no liability shall be assumed nor accepted for any damages, losses or costs resulting
from the use of the product.
Features
 Extreme low output resistance, super current endurance.
 Multiple protection features: Low voltage cut-off protection / over-heat protection / throttle signal
loss protection, etc.
 2 Start modes: Normal/Soft.
 Compatible with fixed-wing aircraft and helicopter.
 Throttle range can be configured to be compatible with all transmitters.
 Smooth, linear and precise throttle response.
Warning!
▲ Do not use more battery packs than rated ones.
▲ Do Not use bad, damaged, cracked or bulged battery.
▲ Over-heat protection function built-in the ESC. when the temperature reaches 100°C during the
operation of ESC, the rotate speed of the motor will immediately reduce; It will automatic recover
when the temperature under 100°C.
▲ Please do not turn off the receiver when the ESC power on.
▲ Please disconnect the battery pack immediately when the model landing.
▲ Handle the model with extremely care and stay clear of the propeller.
▲ Do Not connect the ESC to just ‘any’ kind of power sources. Take care to ensure that the right
polarity of NiCd, NiMH or Li-Poly power packs.
▲ Do Not connect the motor battery to the wrong polarity, or the ESC will be seriously damaged.
▲ Once the motor battery pack is connected, handle the model with extremely care.

Normal Startup Procedure
 Battery cell counting: 2 short Beeps means 2 battery cells; 3 short Beeps means 3 cells, etc.
 Brake detecting: 1 long Beep mean Brake ON; 2 short Beeps means Brake OFF.

Program ESC with the transmitter
1. Switch on transmitter, move throttle stick to the top position
2. Connect the motor, receiver and battery pack
3. Wait for 2sec, you will hear Beep-Beep 2 tones, which means program mode is entered. Then you will
hear another 3 groups of Beep-Beep 2 tones which program setting is entered.
1) Beep- Brake (1 short beep)
2) Beep-Beep- Battery type (2 short beeps)
3) Beep-Beep-Beep- Cutoff threshold (3 short beeps)
4) Beep-Beep-Beep-Beep- Positive/Reverse rotation (4 short beeps)
5) Beep-- Startup mode (1 long beep)
6) Beep--Beep- Cutoff mode (1 long & 1 short)
7) Beep--Beep-Beep- Timing (1 long & 2 short)
8) Beep--Beep-- Heli governor mode (2 long beeps)
9) Beep--Beep--Beep- Set all to default (2 long & 1 short)
4. When you hear the expected Beep, move the throttle stick to the bottom position at any time, you will
enter the setting item. You will hear tones in loop, set the value matching to a tone(as below showing) by
moving throttle stick to the top position when you hear the tone, then a special tone emits, which means
the value is set and saved. Power-off will exit program setting mode directly, or you may keep waiting and
then select other items as the same steps.
Programmable Items
1. Brake Setting: OFF/ON
2. Battery Type: Lipo/NiMH
3. Low Voltage Protection Threshold ( Cutoff Threshold ): Low/Medium/High
1) For Li-xx batteries, the cells of a battery pack is calculated automatically. Low / medium / high cutoff
voltage for each cell is: 2.8V / 3.0V / 3.2V. For example: the voltage cutoff options for an 11.1V/ 3
cells Li-Po battery pack would be 8.4V (Low)/ 9.0V(Mid)/ 9.6V(High)
2) For Ni-xx batteries, low / medium / high cutoff voltages are 0%, 50% and 65% of the startup voltage.
0% means without low voltage cut-off protection. For example, for a 6-cell NiMH battery pack, fully
3
charged volatge is 1.44V*6=8.64V, when “Medium” cut-off threshold is set,
the cut-off voltage is 8.64*50%=4.3V.
4. Startup Mode: Normal/Soft. (300ms/1.5S)
Normal is preferred for fixed-wing aircraft. Soft is preferred for helicopter. The acceleration of the
Soft Mode is slow by taking 1.5S from zero throttle to full throttle. (If the throttle is closed and then
opened again within 3 seconds after the initial startup, the restart-up will be temporarily changed to
normal mode, so as not to cause crash by slow throttle response.)
5. Motor Rotation: Normally, there are two ways to change the motor rotation.
1) by swapping any two motor wires.
2) by programming the setting parameter value of the ESC if when motor has welded with ESC .
6. Low Voltage Protection Mode.
1) Reduce Power: Lower the output power when the voltage reaches preset lowest value.
2) Cutoff: Stop the output power immediately when the voltage reaches preset lowest value.
7. Timing:
Automatic: (7~30 degree)
Low: (7 degree)
High: (30 degree)
Normally, automatic timing is suitable for various types of motors. Please try each Timing to get the best
driving effects. In order to get higher speed and bigger output power, please choose High timing. After
changing the timing setting, please test your RC model on ground before taking off!
8. Heli Governor mode: when Governor Mode ON, the settings of Brake & Low Voltage Protection
Mode will be reset to OFF and Reduce Power automatically.
9. Restore Factory Default Setting:
1) Brake Type: Brake Off
2) Battery Type: LiPo with Automatic Cell detective
3) Low Voltage Cut-off Type: Reduce Power
4) Cut-off Voltage Threshold: 3.0V/cell
5) Soft Start: Enabled
6) Timing: Automatic
7) Switching Frequency: 8 kHz
8) Heli Governor mode: RPM OFF
Cautions!
Warning! Model aircraft equipped with high power motor can kill. High power motor systems can be very
dangerous! High currents can heat wires and batteries, causing fires and burning skin or anything. Follow
the wiring connection carefully! Always fly at the approved field. Never fly over or near spectators. Even
though this controller is equipped with a safety arming program, you should still be cautious when
connecting the main battery.
