My DG is 5m. There would be room for the Gizmo BUT the space is occupied by batteries for the Florian Schammbeck power unit. Later this winter, I will arrange a quick change unit for a Wren Supersport, so it is self launching in two forms. I had some Matchboxes spare, cheaper than a second receiver !!
My BAT will be here as soon as the latest firmware is installed.
