I built a quadcopter based upon the TBS discovery frame, as the APM is located in the frame it is quite difficult to get hold of the status leds.
This is why I wanted to have some kind of Pilotlamp indicating the state of the APM.
I started off wih a prototype (Arduino pro mini with RGB led).
The above video is a small demo.
Plan is to convert it so it can be used with the Xaircraft Pilotlamp
