Fitted upper MLG/fuselage fairings with hot glue, and taped off surrounding fuselage/strut and aft edge of the fairing
Tried shaping with strake fairing foam with dremel router, but it is all too hard and went for sandpaper. Prep sanded surrounds. Note there is a bit of a low spot to port that will need fill, and some covering BID.
Shaped the NACA lip foam to match the line of the cowling, with the leading edge rounded to a 5/8" radius
