This innovative 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. The process is completely transparent - no looking down, no switches required.
Behind the scenes, the elevator trim is repurposed to bend the crow compensation curve.
The script is compatible with all OpenTX transmitters, and all data is stored with the model. So if you migrate to another transmitter, even of a different type, you'll keep all your settings.
For more information, see "Crow-aware adaptive elevator trim" (blog post).
Current version: 3.1 (recommended). Supports all OpenTX transmitters, including Q X7, X-Lite, X9-Lite, X9D, X10/12, TX16S, TX12 and clones.

Tested on the bench with ETC 2.4.0 on RM TX16S, and it appears to work fine. As always, test carefully before use.
