We would be very interested in other club's experience with other
trainers, and what you are using and planning to use in the future.

Our evaluation parameters include high useful load for heavy students
and instructors, ease and availability of parts for maintenance and
repair, *durability for student solo operations, and up front cost ..

Sonex Xenos perhaps? I have no experience with it and am not sure what the
general consensus is (I doubt there is much informed opinion on them since
not too many have been built, so few would have first-hand experience; but
unless I am missing something their performance seems more than adequate
for training purposes.)

Upfront new: ~US$34,000 + ~1200 club man-hours to build.
Side-by-side seating: good for training?
Motorglider: Dispense with towplane costs.
Experimental: Lower part and labor costs.
Sonex provides directions on how to get it registered with the FAA as a
glider.

With a motorglider you do not "dispense with towplane costs" you
"replace towplane costs with motorglider costs" (and quite possibly
many more issues).

I would be surprised if a 24:1 (i.e. non-glider), homebuilt,
lightweight aluminum glider in a tail dragger configuration is meet
many of the practical needs of most glider clubs. I wonder what
getting insurance coverage for instruction on that would take.

The question was to replace L-13 Blaniks and looking for practical
experience. Is there anybody in the USA using any motorglider for
primary training? Can they share cost and operational experiences? How
many students per year go through to complete their licenses?

Wait, I know how about a ASK-21 and a towplane (or winch).

Here are the FAA numbers of all glider ratings, abinitio and add-ons
