To get down to cases,
I know that the 15-S was only a test aircraft and
the canards should be a bit bigger with some dihedral but
decided to just go with what looked right to me.
Just a personal project so no harm, no foul.

First thing is that the plane in the game was a single seater,
so scrapped the rear cockpit and vac-formed a new canopy for openers.
Then just carved up a pair of forward canards out of perspex and built a pair of vector
thrust jet nozzles with the aid of the contents of my
ever faithful plasticard spares box.
