Estes Starliner #0863 Build, Part 9, Wing & Intake Fitting

With the wing dry fitted, a pencil line was drawn where the rear win extensions touched the body tube.

Some 400 grit was wrapped around a dowel and the pencil line sanded off. This removed some filler/primer for a better glue bond. 

The inside edge (root edge) has to be sanded at an angle to fit against the body tube. This took a few tries to get the right angle. Don't sand off too much or you will end up with a gap.

The intake contact points were marked with a pencil. The filler/primer was sanded down as before for a better glue bond.

Here's a pretty good fit of the intakes with a tight contact through the wing slot and against the body tube.

With everything glued in place - here's the view from the rear.

The vertical stabilizers are actually straighter than the camera distortion shows.
