Today Dad and I worked on fitting the Gretz Heated Pitot. Again, as with the lighting, the cutting the wing was the major issue. The other issues were the location of the Pitot relative to the tie down and the access given its final position.
I decided to go one bay out from the access cover and ensure the fitting of the AP roll servo is in the right wing. This should give me enough room for the access and makes for a good mouting of the heating controller.
