Tip for using the GUI

[MDHughes]

Even though you are connecting the Typhoon H to your computer via the USB port, do not change the "Connect Ways" setting to USB! Leave it at SerialPort. (This is under the Edit pull down menu.)
It's totally counter intuitive, but the driver apparently creates a virtual serial port via USB.
Trust me, it doesn't work if you set it to USB...

Thanks for pre warning! Great to know! Amazed at the lack of Yuneec needed information and leaving it all to "US" to figure them out, but then all of the manufacturers do the same!

Sounds like an engineering setting and should have been hidden.
Most controllers use a serial to USB converter so on your computer it is a USB port but on the H it is a serial(RS232) port.
