The Zaggometry is a clever little piece of electronics wich 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. Or in other words, it is a bit like a Flytrex Live flight recorder for your Taranis. The 29€ Zaggomety is developed and produced(!) by Eberhard Rensch in Germany. In this article I would like to show how I installed it in my TBS Discovery Pro and what kind of 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.
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
The image gallery of the first build can be found here.
The video shows a compilation of shots taken in and around Zurich in Switzerland. I was flying above the clouds searching for the sun, blowing autumn leaves in the forest and flying over water and chasing cars. The Discovery Pro is a beast and a lot of fun. Want to build your own? Check out my build log: part1, part2 and part3!
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.
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
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.
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
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.
Detailed setup guide and model files to download after the break. Continue reading
Trekking on Mount Rinjani is a very popular activity on Lombok. With 3726 m (12’224 ft) above sea level, Rinjani is the second highest peak in Indonesia. The most popular access is from either Senaru or Sembalun. Trekking times vary depending on the route and destination. Wikitravel has a good article about it. I’ve chosen the 3 day / 2 night trip witch takes you to two locations on the crater rim, to the hot springs at the crater lake as well as to the summit. It is the most popular option, however there are also shorter tours which only take you to the crater rim.
We were especially unlucky with the weather. It was raining almost every day, which is very uncommon for the dry season. However, the wet season was just around the corner, starting in December, when trekking is not feasible anymore. With ponchos and backpack rain covers we tried to keep everything dry along the route.
The route is not technically difficult but it requires endurance. 8h+ of hiking every day and the total altitude difference of almost 3000m is not easy. I enjoyed the little challenge. With a normal level of fitness and a bit of preparation, everybody can do it. Most difficult was the final accent to the summit. The volcanic gravel stones make you slip backwards on every step and the thin air slows you down on top of it. But I made it and luckily there was even a bit of sunshine on the top. This was very rewarding after all the cold and wet hours to get there. But watch the video yourself I recorded with the Phantom on top of the Rinjani. I guess this is a world premiere.
