This post will explain how to setup instructor and student transmitters so that instructor stick movements will immediately “Take Back” control of the model aircraft being used as a trainer.
It works on Radiomaster TX16S transmitters. The student transmitter can probably be any type of transmitter that can communicate with the instructors TX16S multi-module. The LUA script that is associated with this document didn’t work properly on a TX16S transmitter, so for the moment, no link to it will be provided.
