Estes Condor #0807 Build, Part 12, Engine Mount Gluing & Wing Fins

The instructions have you glue on the wings before gluing in the engine mount. Ideally you want the engine mount on the same side of the launch lugs, perpendicular to the larger wings.

I glued the engine mount in first then set the marking guide with the engine mount in line with the launch lugs on the underside.

The engine mount was set beside the body tube to fins out the distance for the inside glue. I like to place set the glue ring a little below the top ring final position.

A dowel was marked. Glue was set in a ring around the top of the dowel.

Use the lower pencil mark on the dowel as a depth gauge for the inside glue. Roll the bead of glue around the inner wall of the tube.

The instructions have the lower ring even with the low end of the body tube.

I set the mount a bit farther in with the lower ring just inside the tube. This allowed a fillet on the recessed ring edge.

The fin marking guide was printed on the back side of the face card. I made one out of paper.

The two launch lugs are in line with the engine hook. 

The large wing fins are glued on.

Check their alignment visually by looking over and across the trailing edges.
