Crow-aware elevator trim

Description

This popular Lua script is for sailplanes with crow brakes. It allows the pilot to optimise pitch trim in flight across the full range of crow, just using the elevator trim.

The script repurposes the elevator trimmer so that it bends the crow compensation curve. Apply some crow, click the trimmer and the script will adjust the appropriate curve point(s) automatically. No need to look at the screen.

The script runs on any OpenTX or EdgeTX transmitter.
