What about the "crescent wing" protractor version? That"s all I "flew"

[Tophe]

Yeah??? Where is the zwillings then?

Good idea! Thanks for this triple cooperation!

There's also Kit's 12 in/30 cm standard ruler "extended wing" version for high altitudes... ;-)

As a kid in school, this was the best aircraft that ever flew.

Obviously needs Spectrum roundels to make it an Angle Interceptor...

Surely Kit would have used a metre stick...

Fabulous expansion of ideas. Thanks for sharing.

I'm a staunch Imperialist, so it'd have been a yard stick............

Not quite!.  The rod, pole or perch is a rigid item.  A chain (even though Kit would no doubt appreciate a wing 22yards long) is not  so........a floppy wing is not good aero trigonometrical practice!
