MT40A-OPTO-SF32 BLHeli 32bit Firmware Brushless ESCs for Multi-copter/UAV Drone

MT40A-OPTO-SF32 BLHeli 32bit Firmware Brushless ESCs for Multi-copter/UAV Drone/Hexacopter/Quadcopter

BLHeli 32bit controllers are specially used for Multi-copter/Multi-rotors. 32bit mcu are used, enable the controllers have faster and more smooth throttle response than standard controllers.

Main features:

1. Excellent startup performance, great throttle linear and quick throttle response, excellent low-speed performance.
2. Separate voltage regulator IC for MCU (Micro Controller Unit), high capability of anti-interference.
3. Low-voltage protection, block-rotation protection and signal lose protection, etc. All these functions can effectively prolong ESC service life.
4. Programmable by Trx or by a Maytech programming card (optional). Program-Card has a simple and visual surface to conveniently change parameters at any time anywhere.
5. Safe start-up. The motor won’t be started no matter which position the throttle stick is on when battery connected.
6. Motor rotating direction can be changed by exchanging two of three wires from ESC or setting by the Program-Card.
7. Great ESCs equalization, all ESCs can respond to signals from the remote at the same time, bring smooth flying. 
8. Small size and light weight, can be installed into UAV drone's axis arm.
