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.

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 😉

Nomen est omen: Crashpilot

Well, well, we all knew it had to happen. One of my copters crashed. It fell out of the sky, more then 30m onto asphalt. It looked really horrible. The Disco scattered into peaces, it had a totally broken frame with many damaged parts lying around. I could salvage a few pieces from the debris, but I will need to rebuild a new copter from scratch.

Some recovered parts after a crash. The copter fell apart, lost one arm and scattered into peaces.

Luckily nobody got injured and nothing on the ground got damaged. So the worst thing is, that I don’t fully know why it happened. It could have been the almost empty battery, but I could also have been the camera controller board flying into the propellor. I guess I need to do more tests once I have rebuilt  my Discovery.  I just hoped I would not have to build a second Discovery Pro so soon again 🙁

Build Log: Taranis and TBS Discovery Pro, Part 3

In the third part of the build log I would like to cover the setup and configuration of the Taranis RC with the TBS Discovery Pro. After covering the mechanical build in part 1 and part 2 of the build log, this part will be about the wiring and programming of the remote control. Due to a crash I’ve build the copter a 2nd time.
