Yes, nobody is perfect

The GT3C is complicated, very complicated.
The "flashing thing" (and opening, soldering "thing") was not such a problem for me, I love those things.
But understanding the complicated menue is a big problem.
I admit, I probably would never have understood this stuff fully, if there would not be this fantastic "explanation thread" in the German rockcrawler forum by Jens/Amigaman:
https://www.rockcrawler.de/thread/25139-fs-gt3b-anleitungsthread/
There are so many, many, many options, from servo endpoint adjustments, mixing functions, reverse in all channels, different modes of switches, and, and, and...
A pot knob cannot equal this by far.
But without this "manual" (in German - did not find any similar manual in English so far, but my language is German) I would have been lost and never be able to use the full potential of my 8-ch GT3c, furthermore a very helpful community and further
thread for "helping" with so far about 140 pages make the GT3C useful for me.
Never found any "original manual", which probably would be in Czech (? or some other Eastern European language, the developer is from somewhere in Eastern Europe).
One cannot really compare the Dumbo 6ch transmitter with the 8ch GT3c (which for sure is for geeks

).
Would like to have the Flysky Noble with at least 6 channels (better 8 or - as annnounced - 10+)…
