The Fingertech BL-Heli 20A Brushless Speed Controller (Reversing) is engineered for optimal performance in both forward and reverse directions, making it ideal for drive motors. It is specifically designed to complement the “Brushless Mega Spark” 24mm Premium Planetary Gearmotor, ensuring seamless integration and operation.
This speed controller operates on the advanced BLHeli_S software, which is pre-programmed to facilitate forward and reverse operations. It supports a voltage range of 7.4V to 14.8V, accommodating 2-4S lipoly batteries, and maintains a continuous current of 20A. The compact design measures 31 x 15 x 5.3mm without the case and weighs 5.6 grams without bullet connectors, making it a lightweight yet powerful component.
The controller’s firmware is upgradable via the signal wire, compatible with the USB Linker V2, allowing for easy updates and enhancements. It requires an external 5V power source for the radio receiver, as it does not include an on-board BEC. The motor wires are equipped with 3.5mm female bullet connectors, providing flexibility in wiring configurations.
Note: Ensure proper wiring to avoid reverse motor spinning; swap any two wires if necessary.
