Question: I have a VMAR P51D 45-52 ARF. This ARF comes with what looks like an airscoop and another plastic plate like fairing. Where do these go and how do I attach them?

Answer: Both of these trim pieces go on the bottom of the wing. We recommend attaching the wing to the fuselage before applying the trim pieces.

Both pieces are to be centered over the wing joint seam.

The plate like fairing is to be applied near the leading edge of the wing with the flat face forward so that it butts up against the fuselage.

The air scoop is to be applied near the trailing edge of the wing with the scoop inlet facing forward and about 1/4" of overhanging flashing at the back of the scoop overlapping the fuselage. When correctly positioned and overhanging the fuselage at the back, the wing bolts will be accessible with the scoop remaining in place.

Dry mount both pieces and if necessary trim the fit with a sharp #11 blade.

Once dry fitting well, glue the trim pieces to the wing with Pacer Dap-A-Goo. This is a silicone like material that dries flexible and sticks well to the trim pieces and the covering. Apply the Dap-A-Goo to the trim pieces in a thin bead just inboard from the outer edge. Do not apply Dap-A-Goo to the flashing of the airscoop that overlaps on to the fuselage. Apply the fairing first. Wipe away any excess Dap-A-Goo and secure firmly with low tack masking tape. Then apply the scoop and secure with low tack masking tape. Let dry for several hours and then remove the tape by pealing it back upon itself. Do NOT pull the tape off at right angles to the surface to which it is stuck.
