After futzing around the house for most of the morning (including checking the refrigerant pressure in the AC in the van and cutting the oil filter for the plane apart to check that it's pretty clean), we went over to the airfield and took the Magni out. I've stuck one of the camera mounts to the mast, and while there is some jelly effect, it's not terrible. The tablet, stuck to the glovebox in the back didn't work out though - Vic couldn't read it. Oh well, you can't win 'em all. At least both headsets worked OK.
