Thank you for your interest in the Intel Aero drone.
If Radio Calibration says it has detected 0 channels then it means that the firmware is not sending any RC_CHANNELS mavlink messages.
You can try the steps shown in this thread: Detected 0 radio channels. To operate PX4, you need at least 5 channels - Configuration and Flight Modes - PX4 Discuss
The steps there are for Pixhawk but you should be able to do them on the Aero as well.
Hope this helps.
