Many thanks to Aikon for sending me their new SEFM 30A ESC for the tests, which runs the latest ESC firmware – BLHeli_S.
I will test the Aikon SEFM 30A ESC on the thrust stand first, and then later on put them on a quad and try them in real flights.
Why am I excited about this new ESC?
Apart from being rated at 30A (good news for people who like to over-prop their motors), the Aikon SEFM is one of the first electronic speed controller to support BLHeli_S firmware.
We have already covered BLHeli_S before, check out this post to see why it’s awesome.
The ESC’s I received came with BLHeli_S 16.0 firmware, and I updated it to the latest version (16.1) before testing them. The way flashing BLHeli_S is the same as BLHeli, you can either use flight controller pass-through (Cleanflight), or the “one wire interface” method.
The Aikon also has dedicated hardware to generate PWM signal for the motors, which make them run smoother. Traditionally majority of the ESC’s use software generated PWM (Littlebee 20A, XM20A, you name it), it works but it isn’t the best. KISS ESC’s are highly praised for their smoothness thanks to the hardware PWM, and now they are finally facing competition.
- Motor: EMAX RS 2205 2300KV
- Battery: 4S Turnigy Nanotech 65C
- Props: DYS 4045BN, Gemfan 5030, Gemfan 5045, HQ 5040 Triblade, Gemfan 5045 Triblade.
Very interesting to see that the Aikon outperformed both Littlebee 20A and XM20A in terms of thrust.

In the coming days I will be testing these ESC’s on a quadcopter see how they perform, stay tuned.
