Dual rates / Expo

[howard-samuels]

Most radios have the ability to implement dual rates (triple rates on a 3-pos switch), which set the maximum travel for each control surface. And each rate can have its own expo. iNav has profiles, which include a lot more than rates and expo. The ability to change rates and expo mid-flight is useful when you want to switch from a highly-aerobatic maneuver, which may want high rates, to a smooth landing, which may work better with low rates, for example.

iNav allows you to assign three sets of rates and expo (and a whole lot of other things) in profiles. But you can't select a profile with a switch on the transmitter. Using the stick commands to change profile mid-flight is not likely to end well.

It would be useful if rates / expo (or maybe even profiles) were selectable in the Modes tab. For example, one switch on the radio could be used to switch between Profiles 1, 2, or 3 as a mode. Or maybe profiles could be left untouched, but rates and expo separated into something different that could be selected in the Modes tab.

Now you can through programming tab

It looks rather tedious using programming. I wonder what would be the advantage over a dual rate on the radio (e.g. OpenTX), except possibly a bit more precision.
