*Finding the center line of the scoop: one way of doing it: put the scoop on a wooden board, 16 inches wide with a marked centerline. Put the scoop on the board and check equal distance to the board edge at symmetrical points. Transfer the center line onto the flanges on both ends. Painters tape might be necessary as blank label to be able to see pen marks drawn on it rather than drawing directly on the slippery surface of the scoop. | *Finding the center line of the scoop: one way of doing it: put the scoop on a wooden board, 16 inches wide with a marked centerline.

*Finding the center line on the bottom skin: running a cord from mid firewall to the tail tie down isn't really giving you good center line location precision where you need it. Rather the cord is merely a secondary tool to proof that a specific rivet is indeed on the centerline, or that the center line is indeed running between two specific rivets near where the scoop starts and ends. | *Finding the center line on the bottom skin: running a cord from mid firewall to the tail tie down isn't really giving you good center line location precision where you need it.

*The finish kit comes with spherical magnets which can also be used here to place the holes around the scoop circumference where they don't interfere with ribs or other structures.

*The Airflow scoop has a planar top flange for attachment to the bottom skin, however, the RV-10's bottom skin has a 2 degree bend around the middle of the scoop (at the rear wing spar).<br>[[File:2022-08-07 19-13-00.jpg|400x400px]]<br>A good way to reshape the scoop is to heat up the scoop to around 133F and then jam high density foam into the groove above the inlet opening and continuing with additional foam in same groove around the sides to the bend point.

*The evaporator shelf touches the vertical bulkhead support on its front side and sits flush against the inside edges of the longerons.
