I've recently bought a Tx Spektrum DX6i and I would like to program it so I can switch from an APM flight modes to another.
I've follow the process describe by Paul but it doesn't seem to work for me.
When I go to the mission planner software and I switch the button on my Tx, nothing happens. The flight mode remains the same in the interface.
If someone can help me to understand what I'm doing wrong it would be great :)
