Stability and sub trim

[Bacon2002]

Hi,
May I say huge congratulations as this is an excellent application, I am trying to write something similar although somewhat less sophisticated for my own project in .net.
I have set up a quadcopter to work with this application and my initial observations / question - is it normal (when using windows) to experience occassional disconnects of the TX module? Is this a common problem or perhaps isolated to my own hardware - Happymodel ES24 TX module connected via USB. Note that to get this to work I set the jumpers to the lower two pins (main ESP chip). What is the optimum baurd rate over USB for this link?
I hope to integrate the telemetry output from a drone into a PC motion rig although I expect I will need to run a separate link for the telemetry data, any help would be very much appreciated.
If it helps any one I worked out how to implement sub-trim adjustment in the input page by connecting the link of a button (or control) to the side of the sub-trim box.
Thanks again for sharing this great work and project,
David
