Aikon SEFM Mini 20A BLHeliS ESC (Opto) 2~4S

The Aikon SEFM speed controllers are the latest generation and use a variety of leading edge technologies in hardware and firmware to stay ahead of the game. This latest addition to the Aikon range has been designed to be compact but robust enough for lightweight racers where space is at a premium.

What makes the SEFM any different to the other ESC's on the market?
The Aikon SEFM 20A has a totally new MCU that comes with a 3ch PMW output specifically designed for motor control applications and runs at 48MHz. It also has new BLHeli-S firmware which provides all the strengths and advantages of the original BLHeli firmware but adds some significant improvements. These include better response and smoother start-up, 1000 steps of throttle input resolution and auto detection of the OneShot 125, OneShot 42 and Multishot protocols.

Other improvements included are higher quality MOSFET's with extremely low internal resistance, 3 exceptionally fast dedicated MOSFET drivers and extra capacitance to help remove EMF spikes.
