Lua script: crow-aware adaptive elevator trim

Last updated 5 Nov 2019

This script is for full house sailplanes with crow brakes. It turbo-charges the elevator trim, so it can be used with crow brakes. This means that the pilot can achieve perfect pitch trim throughout the crow range, all whilst flying the model. The process is completely transparent

How it works

Under the covers, the elevator trim is repurposed; instead of applying an offset, it bends a crow/elevator curve:

The points to bend are determined automatically by the amount of crow. All this is done under the control of the Lua script.
