30A ESC for multirotor.
This hardware, with the SimonK firmware, gives you the perfect solution for multirotor use.
Highest efficiency 100% N-FET design.
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.

Note (SimonK): Before you buy these, you should make yourself familiar with the somewhat experimental nature of the SimonK firmware. This software pushes the motor response to the limit, so there may be motor and prop combinations that won't work. Due to the lack of overcurrent/overheat/low voltage sensing (needed for multirotors), it's easier to destroy the ESC and possibly the motor too. I can't tell you what will or won't work, other than the motors I sell that I've personally used, so please consult the main SimonK threads on various forums for more info. Neither I, nor SimonK will be responsible for any damage that may occur, so know and accept the risks before using these. That said, I've personally had fantastic results with this firmware and wouldn't use anything else!

Which of the blue cables is positive, which is negative, and which is the signal cable ?

  • also the small cable that hooks to your receiver/distribution board is the +,-, signal that would be black for neg, red for positive, and yellow or white for signal

I have installed these on a 450 quad that im building what kind of calibrating do I need to do

  • depend on what brain you are using ion you used a cc3 it will get calibrated on the computer as you do the set up if you want to calibrate the esc by it self you can do it with the radio or they sell a calibration small board and they can be calibrated with that.

what is a compatible programming card for these esc?

  • If you are talking about a flight controller i would get the KK2.1.5. It is easy to setup and you don't have to worry about cutting the BEC cable.

are thies 3s or 4s esc

  • Manufacturer suggests 2-3s. Going higher than 3s could result in damage. They work well for me with 5200 20C 3s Lipos. As long as they all work out of the box and are calibrated correctly, you can't beat the price.

Are these esc's already flashed with simonk firmware or do they need flashed?

  • Sorry I don't know. I bought them more for price than the firmware knowledge. They work fine though. Getting some more.

will it work well with cc3d and sunny sky motors?

  • I have a -KK2.1.5 with 980kv motors & a Naze32 full with 1100kv motors and both run fine so you should have no problem your CC3D controller. Most CC3D users are 250 mini racer fans if this your choice then the 30 amp may be overkill and over weight .
