I've been using the Celestron AVX mount for 1.5 years and the two major issues have been 'drifting' and 'mount disconnects'. Drift I haven't figured out yet but the 'Mount Disconnects' for me has been solved by completely eliminating the hand controller and connecting the AVX Mount to the computer via the USB2 port on the focus motor. Works great, reliable and no mysterious disconnects since I discovered the AVX mount can be accessed via the Focus Motor's USB port.
So my mini PC sits on the AVX Mount's eyepiece tray and plugs into the Focus Motor's USB2 port. CPWI accesses the mount perfectly. knock wood
SharpCap also has no issues controlling the mount either.
I discovered this connection method by reading a very lengthy technical discussion thread on Cloudy Nights.

Also Note Worthy: I use to access the min PC (MeLE Quieter 3Q) using Windows Remote Desktop but have since made my tripod and mount a semi-perminant setup on my back deck and installed a device made by (J Tech Digital) that extends a keyboard/mouse/and HDMI port up to 350 feet over a Cat6 wire; so I can run everything from my kitchen table. There is HDMI port at both the Sender and Receiver so I can have a monitor, keyboard and mouse active at both the mount and the kitchen table; using Remote Desktop wouldn't allow such a setup since when I'd remote in the local PC keyboard, mouse and monitor were disabled.
