What would it take to convert a primary into a basic soaring machine
(35+ to 1)?

Dear John,

I don't know. But I DO know you're comparing apples to
orangutans :-) The subject is Primary Gliders. Their poor glide
ratio -- typically about 8:1 -- is by DESIGN. That is what's needed
to fulfill their mission, which is to expose a fledgling pilot to 3-
axis controls and introduce them to the mechanics of landing.

You would probably find the syllabus used by early flight-training
programs to be of considerable interest.
