On another issue, when you drilled the sensing hole, did you go through a layer of foam? On some gliders, I'm wondering if the hole should be epoxy lined to prevent water intrusion into a inner foam layer.

On most gliders I know, the nose cone isn't made of sandwich... At least on the symmetry plane where you have to drill, as it is the joint of the 2 1/2 parts of the fuselage.

Looking forward to having one.

PCB modified to include an optional 4 wire led control...
