Nice photos. Are there any complications with not getting the meter on the tail straight to the thrust or center-line?? (ie, if the LE of the meter is Higher than the trailing edge of the meter)
I just knew that was coming. Viewed from the side the elevator hinge line is vertical. It was planned that way. using a set square (Triangle) I draw a line across the tail square to the hinge line. I align the incidence meter to this line.
For filler I use epoxy resin and microballoons.
I have three incidence meters. Once I clamp them on I do not have to take one off to move to another surface to check it.
