SCA-12H commutator controller is designed for installation on aircraft (ship) models with engines of SPEED 280, SPEED 300 sizes.
The product is built on the basis of a microcontroller, equipped with a BEC system (5 V, 1 A) that provides power to the receiver and 2...3 micro or mini servos of the HS-55 /81 type.

The ACO system automatically turns off the drive motor when the battery voltage drops below 6 V for two LiPo batteries (jumper on) or below 5.5 V for 6..7 NiCd/NiMh batteries (jumper off).

To ensure the normal operation of the electric drive, it is necessary to install spark arresting capacitors on the motor.
The receiver is powered by the WEIGHT regulator. When using a separate battery, disconnect the red wire of the servo connector chip.

When the power is connected, the controller is deactivated. To turn on the regulator, move the throttle on the control panel to the lowest position.
After launching the model, the regulator must be disconnected from the battery.
