The story continues.
A contemporary of the Pup was the structurally interesting Fokker Triplane.
With the experience of building the Pup I could really go to town on the scale features even down to using 1mm round balsa to emulate the fuselage steel tubing.
This is the only picture I have taken during construction.

The fuselage is correctly internally braced with cotton thread.
Built to the same scale as the Pup it has a 16" span.

My dad again provided the spun aluminium cowl. It uses the same geared slot car type motor driving a scale prop but this time is has a scale Oberursel that goes round with it inside the cowl.

The final touch is the controls. They are all correctly run back to stick in the cockpit but of course all but the elevator are locked off.

The control line bell crank just has a short link to the stick. The scale control runs actually move the elevator.
It flies very well indeed and is able to 'hang on its prop' at a high angle of attack just like the original.
Surprisingly robust I still have it despite now being over 45 years old.
Now in well earned retirement but it still runs.
