Until now I had an ugly piece of paper taped on the side of my T9X radio to remember the flight modes configured on the 3 position F.mode in combination with the position of the Ail switch. Not only was this ugly but it was not quick enough to read when you needed to switch modes (especially when you 're looking in panic to find the right switch combination to RTL...)
I saw a great customization trick in one of the 3DRobotics IRIS video where they had customized a sticker around those two switches to indicate the various flight modes.
I decided to reproduce this sticker and give the SVG file to the community so you can print your own (and change text/colors). To edit the SVG you can use the "INKSCAPE" program which is completely free and very easy to use:
This is how my custom sticker looks on my T9X:
Once printed, use an exacto knife to cut the holes, that's it !
Attached the SVG file, have fun!
