Cool! It needs to be under 150 to qualify as a FAR 103 UL glider.

How much does one TP wing weigh?

Last ones I built were about 35 pounds each, with ailerons.
They could be 5 to 8 pounds lighter if it were important.
Leave out the false ribs (and the foam false spar that supports them).


How much does the
whole plane weigh, sans engine?

Bare airframe was about 40 pounds on the gear.
But there is still a lot to add to that for a completed airplane.

But if you were after a primary glider style airframe?
I'd guess 50 pounds complete with single wheel.

LOTS of wire...
But wire is pretty light.
