Programmable brushless controller for airplane models. Continuous current 30A (peak current 45A), power supply for 2-4 LiPo cells, switching BEC 5.2V/3.5A, weight 23g, dimensions 37x17x5mm.

Programmable microprocessor controller for brushless sensorless motors for recreational and sports aircraft models powered by LiPo/Li-Ion/LiFe batteries. It uses advanced technology of optimized control, which greatly improves throttle response and power stage control efficiency. The design of the controller takes into account the high endurance and durability required in models with a larger number of servos. The ESCs feature a powerful switching BEC with an optional output voltage that powers the receiver and servos from the drive battery. A special KAVAN PRO LED programming card, which is available separately, is used for easy adjustment of the controller.

DESCRIPTION AND FUNCTIONS OF THE REGULATOR

The controller is equipped with a powerful 32-bit ARM-M4 microprocessor with a clock frequency of up to 72 MHz and is compatible with most brushless motors.
It is suitable for most aircraft brushless motors powered by 2-4S LiPo/Li-Ion/LiFe batteries.
Special supply stabilizer for the microprocessor for high noise immunity and reducing the risk of loss of control.
Optimized control technology significantly improves throttle response and power stage control efficiency, and lowers regulator temperature.
High performance switching BEC with the output voltage adjustable to 5.2V, a continuous load of 3.5A and a peak load of 5A. The BEC is isolated from the other regulator circuits and can maintain its proper function even when the power board is connected to the MOSFET - The transistors of the regulator burned out.
Start-ups Normal/Soft/Very soft are suitable for normal propeller aircraft and models with electric ducted fans.
Simple programming and adjustment via transmitter or KAVAN PRO LED programming card.
Using a special programming cable to connect the controller to the LED programming card, the user can program the controller anytime and anywhere (please refer to the KAVAN PRO LED programming card user manual for details).
A series of protection functions: starting protection, controller thermal protection, capacitors thermal protection, overload protection, overcurrent protection, supply voltage abnormal protection and control signal loss protection, effectively extend the life of the controller.
Gas calibration for perfect adjustment to the control signal of your RC set.
PROGRAMMABLE FUNCTIONS

Brake type: brake switched off, normal brake (with braking intensity adjustable in 7 levels).
Braking power: The braking intensity is adjustable from level 1 to level 7 for the "Normal brake" mode.
Motor shutdown type: Soft shutdown: The controller gradually reduces the power to 50% of the full power within 3 seconds after the voltage protection is activated. Hard shutdown: The engine shuts down immediately.
Number of LiPo cells: We recommend manual setting for 100% reliable voltage protection function. The controller automatically calculates the number of cells in the connected battery according to the "3.7 V per cell" rule if you select automatic detection.
Voltage protection: The voltage protection threshold is adjustable in the range of 2.8 to 3.8 V/cell. The protection can also be switched off completely.
BEC Voltage: Supply stabilizer BEC voltage is fixed (5.2V).
Start: Normal start (instant start), Soft start (with slow start for engines with large propellers, gears or smaller impellers), Very soft start (with very slow start for engines with large propellers, gears).
Timing: Adjustable in the range 0-30°.
Direction of rotation: clockwise/counterclockwise.
DEO free running: This function can be switched on or off. It can result in better linearity or a more consistent gas response.
PROTECTIVE FUNCTIONS OF THE REGULATOR

Start-up protection: The controller measures the engine speed during the start-up process. If the engine speed stops increasing or if the increase is no longer stable, the controller judges it as a false start. If the throttle is less than 15% at this point, the ESC will automatically attempt to restart the engine. If the throttle is more than 15%, you need to pull the throttle stick all the way down to restart the engine.
ESC thermal protection: The motor will “stutter” if the ESC temperature exceeds 110°C, indicating that thermal protection has activated. At that moment, if you pull the throttle below 60%, the "stutter" will disappear and the controller will deliver the power appropriate to the throttle channel. If you move the throttle channel above 60%,
