Crow-aware elevator trim

Last updated 19 Sept 2020

Description

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

Behind the scenes, the elevator trim is repurposed to bend the crow compensation curve. The process is completely transparent.

The script is compatible with all OpenTX transmitters, and all script settings are stored securely in an OpenTX curve. This makes it easy migrate to another transmitter, without losing your settings.

For more information, see "Crow-aware adaptive elevator trim" (blog post).

Note 15 March 2021 - The file permissions of adptr3.lua were incorrectly set to 'read-only', preventing the script from running. This has now been fixed.
