for sale is 4pcs 30A SimonK firmware Brushless ESC. Soldered with 3pcs 3.5mm gold female plug, very convenient to connect motor. Highest efficiency 100% N-FET design. Highest accuracy with Crystal Oscillator (Temperature won't affect the PWM operating range like other cheap ESC's). No low voltage cutoff, because any cutoff in a multirotor = crash. No over temp cutoff, because any cutoff in a multirotor = crash. Super high refresh rate, no buffering of the input signal, resulting in more than 490Hz response rate. 16KHz motor frequency, giving fastest response of the motor, and quietest operation as well (no 8KHz squeal). Super simple, foolproof operation! Nothing to program other than the throttle range. ESC Specs: Cont. current: 30A Max. current: 35A Input Voltage: 2-4S lipo / 4-12 cell Ni-MH/Ni-Cd BEC: 5V 2A (Linear modeļ¼ Size: 55x26x8mm (length 145mm including power cable) Weight: ~22g

One cooked off on testing, otherwise good for the price.
Lets face it, these ESC's are really inexpensive.Initially all four worked well, I calibrated them successfully and tested them individually. Unfortunately one failed on testing. I took it apart and found some relatively poor soldering.So, make sure if you're building a quad you order extras and remember that these are probably not for your high-end multirotor as they're built to a price.

So Far So Good
These ESC'sare great (so far). Plenty of wire and well made, with plugs at one end its so much easier to just plug the motors in and get the right direction with no soldering. Although I haven't put these through their paces yet, I would recommend for value and ease of use. Delivered in good time. I will update if any issues arise.UPDATE Worked well for 5 minutes then 1 failed, getting very hot, and unusable. Ordered 1 more hopefully was just a glitch.

Works perfect. The Quad now actually flies
I am building a Robocat 270 and unfortunately once built I couldn't get it off the ground. One motor was seemingly much more powerful than the others. After a lot of testing and 'net research I found 3 of the EMAX ESC's the kit came with seemed to result in less power to the motor than the other one. So bought these to replace them. Works perfect. The Quad now actually flies! Great price too.

great esc's for the price
great esc's for the price and id defiantly recommend them i can feel safe knowing these are on my quad knowing they will keep it in the air i would defiantly recommend them.tested with the dji f450

At the price they are good,
They work well on my Y6 Y650 Scorpion with 1100kv Turnigy motors and 4s battery. At the price they are good, i would recommend these.
