Agreed on the backup disc. It has been removed as it does not make sense. Ikarus is working on an english manual, so hang on.

As for the re-installation, you don't have to re-download using the Download Manager:
1. The Download Manager downloads all needed files and stores them in C:\<User>\My Documents\aeroflyRC7-Installer.
2. The latest download files is the Setup.exe
3. This Setup.exe will automatically be started when the download is finished, and controls the native aerofly installation.
4. The previous download files ( stored in: "C:\<User>\My Documents\aeroflyRC7-Installer" will not be deleted automatically.
5. The only thing you have to do after uninstalling aerofly7 from your PC is to start the Setup.exe again, located in "C:\<User>\My Documents\aeroflyRC7-Installer"

On your intermittent connection, please post a photo of your cable connections from the radio to the computer. This will be helpful to assess the problem.

As for dual rates, you should use the rate switches in your radio but calibrate with rates at high, not low. You could use the programmable mixes in your radio but disable them when you are doing calibration.
