The Zaggometry is a clever little piece of electronics which can read the NAZA GPS coordinates of you copter and send it over the telemetry link down to your Taranis RC-remote for display and logging. In other words, it is a bit like a Flytrex Live flight recorder for your Taranis. The 29€ Zaggomety was developed and is produced(!) by Eberhard Rensch in Germany. In this article I would like to show how I installed it in my TBS Discovery Pro and the data I logged during a test flight (video).
I usually never change a running system but I wanted to play with some new telemetry sensors and all the new LUA scripting features of the openTX 2.0 on my TBS Disco Pro. This is (not yet) an official FrSky firmware. They are stuck at some older, feature restricted 1.x version and they might never offer some of the newer features, as they consider the Taranis a feature complete product. Well, I don’t.
