Martian II - First Build
19/8/17 - Build, maiden hover and checks complete. Rotated the Racerstar 4in1 to have power pads to the rear. ESC signal cables matched to the correct motor. Build is running a reversed prop setup in Betaflight. Electrical tape used to mount vtx and rx.

The ESC cable colours need to be soldered to the following motor signals on the flight controller.
M1 - ESC Cable Blue.
M2 - ESC Cable Yellow.
M3 - ESC Cable Orange.
M4 - ESC Cable Green.

I have not connected the black wire.

You will then simply need to reverse motors 1 & 4 direction. I myself used the BL_Heli configuration app in Chrome, simply connect to the flight controller using the USB and it will pass the signals through. It is very easy and straightforward.
