Timothy Dawson has been building, designing, and flying model aircraft
and helicopters since 1968. He flies scale airplanes and helicopters,
competing in the Nats as well as various international contests.
When starting a new project, I like to investigate the aircraft I am modeling as much as possible. The Internet has made this easy because all of
the information you could want is right there—unlike 42
years ago when I first got into this hobby.
The model I chose is the ARUP S2. I wanted
something unusual and I love flying wings! I found
limited information on this aircraft, but I obtained a
three-view drawing and a couple of photos, so that is
what I used for the build.
There is a set of plans on the market, but they are not
identical to the original aircraft so they were of no use.
I set out to make my own templates (paper cutouts),
traced the outline on the garage floor, and went to work.
As work progressed, you can see in the photos how I
maintained the shape and a true-to-scale outline of the
Now for the fun stuff: fabric, rib stitching, and pinked
tapes. After the fabric has been applied and the edges are
sealed, it is time for rib stitching. It is not difficult and
adds visual appeal to the finished model. It takes a little
time, but you will be rewarded for your efforts!
I use a 12-inch piece of 1/8-inch copper tube. I
flatten one end so I can drill a hole for the
thread and sharpen the other end to
ease in pushing it through the
fabric. I like using carpet
