Bob, I see you’re in Somerset.
If Neils happy with the suggestion then the Auri could make its way to Frome by the 15th August - if that was any help…
(I’ll be seeing Neil at Upton upon Severn on the 14th and could bring it home with me).
The TEK probe is a standard RC Electronics (V-tail) probe, I have just made a streamline fairing from balsa and covered it in black solarfilm. All the GPS gear is fitted to a slide-in keel plate, which slides in as far as the TEK probe mount which is a small block of ply glued on the inside of the nose cone. The probe is positioned such that I can fit the battery in front (via the hatch) - it is prevented from sliding back by the probe mount & pipe. The Sparrow unit is on a flat plate at the front of the keel, at a height which means it just contacts the top of the nose cone. The RF module is on one side of the keel on Velcro, and the TEK pressure sensor on the other side (see photo). The RF aerial goes forward along the floor of the nose cone, partly under the battery. No link issues so far.
