My third radio, and the first one I chose for a reason that never appears in a review: it fits in the top box of a GS Adventure alongside two drones, goggles and batteries. What the six customisable function switches actually enable, and where the GX12 loses to a Boxer.

How EdgeTX customisable function switches, an RGB colour per subsystem, and one AND slot per logical switch turn eleven threshold detectors into three things you can switch on and off.
