Hi, I've looked around the web to get an understanding the setup of the Ardupilot flight modes with a Spektrum DX6 2nd generation and there was none. So I decided to write this blog. The few things to consider when doing this: Please follow the instruction given on the ardupilot webpage . Have the Pixhawk hardware connected to Mission Planner (I have 1.3.50 - Copter V3.5.3)  Use the display bar in the Radio Calibration page as a guide while changing the rate pulse widths on your transmitter. I've used switch D to change the pulse width ranges on channel 5.

So my pixhawk has finally arrived! Now it's time to get to understand the codebase and integrate my algorithms to the flight control suite. I've also gathered a few parts from a research quadcopter. The plan is to have it takeoff and demonstrate that it works!
