I have a Spektrum DX6i that I purchased for my quad. At first everything seemed to be working fine. I was able to connect my ESC's to the RX and calibrate them. I did this for all four then proceeded to connect my AMP/IMU and run the calibration tool. I followed the steps, adjusting my transmitter (some controls were reversed) and save the calibration.

I then disconnected the quad and went into testing. After arming I was able to get some results both by moving the controls and by rolling and pitching the quad. At this point it didn't seem to be functioning right so I went into troubleshooting. I made sure the code was right and re-calibrated everything but more issues showed up.

Now when I connect APM/IMU I get a beeping as though my ESC are not calibrated. When I try to calibrate them (ESC connects to RX, turn on TX w/ throttle up, connect battery to ESC, throttle down) I get no response.

Also, depending on which ESC I am trying to calibrate the RX LED will begin to fade 5-10 seconds after connecting the battery.

I have tried binding the TX/RX and still get the same issues. Is it possible that I damaged the RX or ESC? I have been very careful not to blow the outputs on my APM as well.

Any advice would be appreciated.
