I am build a new 3DR copter and am having some trouble/questions connecting the RC electronics.

I have a new Spektrum DX8 radio and AR8000 receiver. I have connected the APM to the receiver using 6 - 3 wire connectors.

With the latest version of Mission planner I can connect, update firmwar, and see real-time GPS and other sensor activity.

I do not however see any radio input. The receiver has been bound to the radio, and the bind light is solid.

I have attached a picture. I do not have the custom cable mentioned on the wiki - but it seems to suggest this way will work also.

Do I have something wired wrong? Backwards? Any ideas?

Thanks!

Have you binded the radio to the receiver while plugged into the APM ? It will not work if you bound to the receiver without the APM. See this thread http://www.diydrones.com/forum/topics/spektrum-dx8-and-ar8000?xg_so...

How are you testing radio input? Just moving the throttle, or via MP->Configuration-> Settings -> Radio? or via CLI test->radio?

Do you have the APM powered from the servo rail, or only via USB?

Because of the wash out on the rx I can not tell if it is mounted up or down. But the signal side of the cable on the rx is to be at the bottom, the opposite of the APM. The manual never states this. Put the white on the bottom on the RX.
