Hi all welcome to this short article on Simon K esc’s buy guest writer VertigoUK
What’s Simon K I hear you ask?
Simon k is basically the firmware running on the esc it has been custom made for esc’s by a guy names Simon Kirby it interprets the input signals from your flight controller and battery, determines what to do and sends the correct voltage to the motor.
Wait a Minute, What’s Firmware?
OK back to basics. In every digital electronic item there are microchips or microcontroller units built on to the circuit board. The firmware is a special piece of code that takes an input signal processes it and then sends out the resulting signal. Esc’s are no different.
Why can’t I just use stock firmware?
In short you can quite happily use stock firmware. However with stock firmware you are stuck with the processing that the factory says. Custom firmware such as Simon K allows you to tune the esc a little better for faster response times and it also allows you to get around some unwanted safety features built in to the esc.
Why do I need Simon K?
Why do we need anything in life? Because it gives us the freedom to do as we wish.
For example on a stock esc when the battery gets too low most esc will just cut power to the motor. Not what we want when we are 400ft in the air. With Simon K esc’c the motor will just keep going although you risk damage to your batteries. In my opinion replacing a battery is a lot better that replacing a whole multirotor.
Simon K firmware has also been known to increase response times and increases compatibility. Simon k firmware is constantly being tweaked and updated. The big advantage is that the firmware is open which means you can modify the code to how you like it. In my opinion it is definitely worth the extra cost purely for the faster response time and freedom to modify it however I want.
The other advantage of Simon k is that the compatibility is that good it can even be used to start any motor providing the motor isn’t fried.
OK You have twisted my arm. How do I get it?
Getting an esc flashed with Simon k firmware is easy they are available from most RC dealers. However if you wish to modify the code or turn your own esc into a Simon k esc you will need a Simon k flashing tool which is compatible with your esc.
How too guides are available via a quick Google search.

It is also worth looking up BLHeli firmware, as this has arguably surpassed that of SimonK’s.
