HELP! I am trying to get these ESC's to work with the HK megaPilot (Pixhawk). The ESC's calibrate fine with fine linear response, but when I run them through my Pixhawk they lose are their sync and are un-useable.

Can this ESC be flashed with "Atmel Atmega Socket Firmware Flashing Tool " ? And which SimonK firmware would be best to flash it?

how do you turn the brake off
 Callum 53 points
You'll need a hobbyking ESC programming card like this one: PRODUCT ID: 9261000016 .

hi Karen,you can get a programming card but you really don't need it.go to files and download manual =start reading operation V.when you set programming mode you just have to wait until you hear the sequence tune is played for brake off(then pull throttle stick back to lowest point to set it).remove propeller from plane first before you start programming esc.dont cred happy to help good luck:)

is it pre sadered

The ones I received did not have any connectors soldered to the cables. I had to add the XT60 for battery and bullet connectors for motor.

the receiver plug is, all others aren't
 handyjap 660 points
You are correct Callum. It had a receiver plug but not battery or motor connectors.

What is the MAX mah this can handle for a 3s lipo battery?
 handyjap 660 points
A battery with "Constant Current" * "C Rating" =< 20A I would expect.
 Callum 53 points
there is no max mAh an ESC can handle as far as I'm aware.
