Main section​

Programmable functions of the KAVAN ESC​

The highlighted values are the default factory settings.

  1. Brake: ON/OFF
    • ON: Sets the propeller to the brake position when the throttle stick is at the minimum position (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 Cut-off type: Reduce Power/Hard Cut-off
    • Reduce Power: ESC reduces motor power when the preset Low Voltage Protection Threshold 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)
    • For Li-xx packs: the battery cell number is calculated automatically. The Low/Middle/High cut-off voltage for each cell is 2.85/3.15/3.3 V. For example: For a 3S LiPo, when the „Middle“ cut-off threshold is set, the cut-off voltage will be 3.15×3 = 9.45 V.
    • For Ni-xx packs: Low/Middle/High cut-off voltages are 0/50/65 % of the startup voltage (i.e. the initial voltage of the battery pack), and 0 % means the low voltage cut-off function is disabled. For example: For a 6-cell NiMH battery, the fully charged voltage is 1.44×6 = 8.64 V, when the „Middle“ cut-off threshold is set, the cut-off voltage will be: 8.64×50 % = 4.32 V.
  5. Soft Acceleration Startup: Normal/Soft/Very Soft (300 ms / 1.5 s / 3 s)
    • 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 is slower, it takes 1.5 seconds 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 speeds, High timing can be set. Some motors require different timing setups therefore we suggest you follow the manufacturer-recommended setup.
    Note

    Run your motor on the ground first after making any changes to your motor timing!

  7. Music/LiPo Cells – not used.
  8. Option – not used.

Wiring sequence​

Connections of the KAVAN programming card
Caution

Program the ESC after installing it in the model, with the motor connected. Remove the propeller for safety.

  1. Disconnect the main battery pack from the ESC.
  2. For the KAVAN ESC (with a built-in BEC), please disconnect the Rx cable (trio wires) of the ESC from your receiver, and then connect it to the program card at the top right corner position marked with „BEC“.
  3. Connect the main battery pack to the ESC.
  4. The LEDs on the program card will light to show the current programmable values of the ESC.
Note

The sequence of Step 2 and Step 3 cannot be reversed! Otherwise the program card cannot work properly.

Caution

Don’t use a battery pack with a voltage higher than 6 V to supply the program card!

Operation​

Programming a KAVAN ESC with the transmitter

For the alternative transmitter programming method, see (Fig. 2) and the KAVAN ESC manual.

Press the Up/Down ⮝ / ⮟ button to select the programmable item; its LED will blink. Press the Left/right ⮜/⮞ button to select the value indicated by the flashing LED. Press OK to transmit the settings to the ESC. The blue „Connecting“ LED blinks during transfer and stops when the settings have been accepted and stored. To restore the factory defaults, press RESET, then OK.

Appendix​

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 are correct.
  • Never use ruptured or punctured battery cells.
  • Never short circuit battery or motor terminals.
  • Always use proper insulation material for cable insulation.
  • Always use reliable, polarised cable connectors.
  • Wrong battery polarity will damage the Card and ESC and void the warranty.
  • Use only batteries supported by the card and ESC. Do not exceed either device’s specified supply voltage, and ensure the correct polarity before connecting.
  • Once the battery is connected, handle the model as if the motor could start at any time. Keep fingers, your face and loose clothing away from the propeller. Keep yourself and bystanders out of the plane of rotation and never stand directly in front of rotating parts.
  • Do not immerse the Card under water, do not allow it to get wet while powered up.
