some of your issues sound like they could have been solved by rebinding.
Actually, perhaps not Mickey. I experienced this "beeps of death" thing as well with my H and called customer service while it was occurring. Turned out the ST-16 was still bound but lost calibration, requiring accessing the "secret menu". Re-calibrating the transmitter functions is a simple process but you need to do it correctly, starting with the slider controls centered. There's two pages of transmitter calibrations as shown earlier in this thread, performed one at a time and then exited. Don't go back and forth. There's little or no need to delve into the other stuff.
