In this video I show how to install the Yaapu Horus Mapping Widget and LUA script on your colour LCD OpenTX transmitter. This is named Horus, but it will also work on a Jumper T16 and T18, and the RadioMaster TX16S. We go over the process of downloading the map data, setting up a switch for the zoom levels, setting up the sensor data on the bottom and right, and getting everything installed and working on the transmitter.
IMPORTANT UPDATE
If you are having problems with GMapCatcher, and you get mostly tiles that read "We are sorry, but we don't have maps at this zoom level for this region..." Please go to github.com/heldersepu/GMapCatcher/issues/479 and mention that you are having this issue.
UPDATE: 7th Feb 2021
Since making the video, Yaapu has turned down the pull request for the mapping zoom levels as they are in this video. However, that is because he has also been working on an update to the widget as a whole. Since speaking with him, he will be adding settable zoom levels. So you will be able to have zoom -1, 1, and 3 for example. But, the implementation will be slightly different. When it is released, I will make a follow up video. However, I have no control over timescales for this at all.
