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.

I think the manual does not specify because it is receiver-specific. All of my futaba receivers are signal on top, +5vcc in the middle, and ground on the bottom, with "B" (input power) on the highest channel. As the manual has no idea which receiver you might have, it only shows the connection logically.

Thanks Mike and Matthew - you were right, the Spektrum receiver has the signal on the bottm (5V in the middle, GND on top) - nothing on the pinouts inthe Spektrum manual

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?

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...

I could not rebind yesterday, but once I got the input wires properly connected, I was able to rebind and now have successful communication between the APM and the RC receiver!  Thanks all.  

 

Hopefully motors come today and then more testing  :)
