ONLY 4 LEFT--30A SimonK ESC Brand New


Starting my own line of multi-rotor gear beginning with these ESCs.

ESCs have been flashed with SimonK firmware, re-wrapped and bench-tested to ensure quality.

Each ESC also features three solid-gold 3.5mm female bullet connectors.

Royalty will be paid to Simon Kirby for each ESC sold. I have 4 still available.

Here are the technical specs:
  • Constant Current: 30A
  • Max Current: 40A
  • BEC: 5.0V / 3A
  • Input Volt: 6V - 12V
  • Size: 56mm x 24mm x 8.5mm

Price is $18/each and that includes free shipping from the US to anywhere in the US via USPS Priority mail.

All payment through PayPal.

Thanks!

Great idea i hope your business does really well i know that it's way too hard for me to flash escs so this will be great for all the guys who aern't the best solderers.

What does the SimonK firmware do for the esc? Is this for quadcopters?

Yes, this is for multicopters (tris, quads, hexas, etc.). The SimonK firmware essentially sends speed commands to the motor in real time rather than averaging the PWM (which is what planes and helis need). This results in a higher refresh rate.

The higher the refresh rate, the more smoothly the multicopter flies as the flight controller is constantly speeding up or slowing down various motors.

Multicopters using SimonK-based ESCs fly like they are on greased rails!

I did not manufacture the ESCs myself, but to the best of my knowledge they are N-FET only with external oscillator. I will message my supplier to confirm.

You bet. As soon as I get the cash flow going I really want for us to have a great multi-rotor only supply source right here at home. I am tired of waiting forever for stuff.

I'm looking for replacements for my DJI 450, will these work if I pull the power wire out of the servo plug?

If so, I'll take them.

Thanks,

Jim
