Graupner ever since I stated flying over 26 years ago.
MC18, 20, 24, 24 Gold (all JR made), and now MC32 Hott (SJ made). Does all I want it to do, reliable transmission, and telemetry from day one. simple, clear programming, no fancy bells and whistles ( who really needs an MP3 player in his transmitter, of colour screens you can't read when the sun shines on them??)
Bottom line, "Deutsche grundlichkeit ohne Spielerei".....
