This is a new version Aikon BLHeli_S speed controller supporting 3-6S LiPo batteries.
Aikon SEFM 30A ESC is the new generation of multirotor speed controller with the latest BLHeli_S software.

Aikon has been working closely with BLHeli group in developing the product for FPV racing community, and Buddy RC is proud of being the first dealer in the world to carry the product.

SSKaug stated the features of the new BLHeli_S program in the above thread as:
"BLHeli_S is an improved version of the base BLHeli code.
BLHeli_S delivers a throttle response that is Smooth as Silk, and the main factor contributing to this, is that it uses hardware to generate motor PWM.
Two MCUs support this for BLHeli_S, namely the BusyBee1 at 24MHz (EFM8BB10F8) and the BusyBee2 at 48MHz (EFM8BB21F16).
BLHeli_S will have the same good Sync holding properties as base BLHeli. Maybe even better.
BLHeli_S generally does Startup better than base BLHeli.
BLHeli_S does damped light. Only.
BLHeli_S has motor PWM that is Synchronous to the MCU master clock, as it is generated by hardware.
This makes the motor Silent.
BLHeli_S has very Small throttle Steps. The resolution varies between hardware configurations (MCU clock speed and driver type), and is between a nominal 512 steps and 2048 steps.

BLHeli_S supports very high motor Speeds. A BB1 MCU will support 350k erpm, and the limit of the BB2 is not yet known, so the code is set to limit at 500k erpm.
BLHeli_S supports regular 1-2ms input signal, as well as Oneshot125, Oneshot42 and Multishot. Autodetected when the ESC sees an input signal.

Last and by no means least, is Simplicity. If you have a regular setup, just install and go fly (calibrate if your throttle range does not match BLHeli_S default). Or if you need to configure or update, just do so with the Simplicity offered by connecting to your ESCs through the FlightController, using BLHeliSuite and a USB cable."
