Zaggometry: How to log your flights with the Taranis

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).

Taranis upgrade to openTX 2.0

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.

I did it again! 2nd Discovery Pro build

As we all know, my first TBS Discovery Pro crashed horribly with no hope for easy repair. So what should one do with all The FPV gear and not model to fly? Right. Build a second TBS Discovery Pro. It should not take too long, as I’ve documented my last build in detail  (build log part1, part2 and part3). This time however I want to make some minor modifications:

  • move the X8R receiver inside the frame next to the NAZA instead of having it sitting on the back outside.
  • repositioning of the video antenna to the top of the frame for better reception
  • Add RSSI connection for the OSD
  • Put the GPS puck on the stick for better reception

How to bind X8R to the FrSky Taranis in different modes

The official instructions for binding the X8R receiver to the Taranis are quite confusing and cryptic. Therefore, I try to give step by step instructions about how to bind them in the different available modes as well as some background information. The whole process is split into a preparation phase, mode selection and a binding procedure.

Spring in Zurich

Today was a beautiful warm spring day and I decided to do what all the people from Zurich are doing, going down to the lake. While the promenade was severely crowded, I had the sky all for myself 😉
