Setting up 3DR Radios, APM 2.5, and the Spektrum DX7s

Having some trouble setting up the 3DR Radios and pairing it with the Spektrum DX7s in order to proceed onto the ESC calibration step. 

I've followed the instructions for the FTDI-to-USB setup here: https://code.google.com/p/ardupilot-mega/wiki/3DRadio

Specifically, there are two areas of confusion:

1). After pairing the 3DR Radios from those instructions, I'm unable to verify the telemetry by using the Connect button from MP to the APM2.5 when powered by the LiPo (no lights appear on the APM, GPS, or 3DR receiver although the ESCs make a noise and sometimes the motors shift a few degrees). I can only connect and get green lights on the 3DRs when connected via USB.

2). How does one pair the Spektrum DX7s with the 3DR radios? Instructions for this particular configuration are hard to come by and or don't fully explain what to do.

Thanks for the assistance!

  • Why do you want to pair the DX7 with the 3DR radios? Transmitter and Telemetry are independent of each other.
