Here's the plan for my 22" span Short Seamew on two A2 sheets. The model has proved to be an excellent performer, and flew a 2 minute max at the 2016
FAC Nats. All outlines are scale, at least according to the drawings I used, but dihedral has been increased for added stability.
In this view of the uncovered model you can see how I had to make my outer wing panels removable at the
dihedral break to get the model to fit in the transport box I take to the USA. The tongues and boxes
are not shown on the plan because on a model this size you wouldn't normally need them, and you will save 3 grams or so on the airframe weight.
Also visible are the interlocking wing tabs which glue into the box that runs across the fuselage. These locate the wings accurately and
provide strength across the fuselage in the event of a wingtip landing. The rubber motor passes under the box.
I would strongly recommend using pre-shrunk tissue for covering the tailplane to stop it warping. Although not shown on the plan, you can
see how I added some local filling to the tailplane using soft balsa to give me something to glue the tailplane slots on to.
Also in this view you can see how much of Lindsay Smith's canopy moulding I used, i.e. the two bulged sections plus parallel section between them.
The new windshield is folded from flat sheet. Matching that to the front canopy was probably the trickiest part of the whole build.
This photo should be useful for undercarriage details. The outer sections of the yokes to retain the wheels have yet to be added.
The offset exhaust position can also be seen. I made mine from balsa, but a suitably sized piece of tubing would also do the job.
The fixed leading edge slots are quite simple to make and add some interest to the model.

To prove it actually flies, here's the Seamew in action at the Oxford Model Flying Club "Scale Fest 2016" meeting - well under maximum winds, but the open rubber class here was judged on realism, not duration.
Thanks To monique Lyons for the video.
The two plan sheets are A2 size, and can be tiled to suit the paper in your printer using Acrobat reader.
