Estes Colonial Viper #1310, Part 6, Wing Cutting & Gluing

The wing fins are three pieces. Note the grain on the two mirrored pieces.

The wing extension pieces is glued into the notch in the front piece.

I didn't glue the extension piece in yet, I wanted to sand the root edges flat without the extension piece in the way.

Setting the wing on the flat sanding block shows the bottom root edge wasn't flat. Now the root edge is trued up.

The the extension is glued in place.

Notice the pencil line in the instruction picture above. The bottom of the extension piece should be parallel to the root edge of the fin.

The wing and rudder pieces got a coat of CWF.

The picture on the left shows some balsa warping when only one side has the water based CWF coat. Don't panic - Painting the other side will straighten it things out after the filler dries.
