I have been able to follow it after watching several times. This was my first attempt at programming a RX. I have been able to execute every step in the video except for the P-Mix. I have been stumped on that one. That is where you establish a Failsafe switch.
The P-Mix is actually pretty simple concept once you get the hang of it.
it basically at the fliptakes the info from one parameter (like Aileron) and apply it to another (like Rudder/Yaw), so that when you move the Aileron it will move the yaw as well. (which is knida nifty). But sometimes you don't want a 100% to 100% correlation, so they offer a curve so you can adjust how much it affects the other channel.
But you also have the option of applying that a channel to itself instead of another channel, so basically using that curve you can change it so that it merely alters the channel a different way. -example : a 50% curve will make it so the channel only reacts at 50% range or something.
Similar curves can be applied to a channel that's being controlled by a switch, such as the GPS/ATTI switch. When the switch is set to GPS, the signal being sent out is something like -620 (between the rangef -1000 to 1000) so if the signal is near that number, it will set the NAZA to GPS, and then when it's at 0 it's ATTI, and around 620 it's either ATTI/Manual.. or the new option of Failsafe (which almost negates the need to set up a separate failsafe switch anyhow, but there might be desire to set up a separate failsafe switch).
So the NAZA is pretty clever, in that if the signal is somewhere between any of those settings, it will put the MC into failsafe mode. So when you set up a simple curve (which looks more jagged than a curve!), and apply it to the channel, it'll tweak out everything so that instead of -600,0, or 600, it'll result in -310, 310, or +930 and Failsafe will kick in.
Hope that makes some sense, as I'm definitely not a pro at it, only had my Tx for 3 months, but fortunately it all clicked once I started messing around and learning what everything did.
I discovered an improved method for setting up failsafe on a separate switch that doesn't interfere with the AV2 channel that other online tutorials implement. made a quick video to show
