I wanted to share the integration i have done  in my jdrones Quad.

On the dome i have the Mediatek GPS.

On the first deck, the FrSky Receiver, 1.2 Ghz Video Transmiter and Xbee Telemetry

On the second deck, MinimOSD, APM 2.5 and jD-IOBoard.

The setup includes sonar and Battery monitor in one on the legs.

Each arm has a led strip driven by the JD-IOBoard

The weight with a 3S5000 Lipo is still below 1.5Kg and so far I have got 15 minutes of flight time.
