Description
A high-voltage, no-BEC (Battery Elimination Circuit) electronic speed controller for RC aircraft, rated for 6-14S LiPo batteries and featuring a 32-bit ARM M4 microprocessor with Driving Efficiency Optimization (DEO) technology for improved throttle response, efficiency, and stability. It includes multiple protection features, selectable soft-start modes for propeller and EDF (Electric Ducted Fan) jets, and a separate programming cable for use with an LED program box. The "Opto" and "No BEC" designation means it relies on a separate UBEC or other power source to power the receiver.
