I've built and test flown 3 sailplanes, one that was our own design.
Each one was initially flight tested by me using the "crow-hop"
method. I would be happy to share with you what my process was and
what was learned from these tests.

You can contact me directly via Bob K thru the hpaircraft website.

Or you can ask the smart guys here who have never built or crow hopped
a sailplane.

Dick gave specific admonishments to low time pilots not to do their
own test flying. Great advice, imo.

So, let's clarify. "Crow hops" are commonly done by very experienced
pilots, acting as test pilots for new designs or homebuilt aircraft.
They are doing crow hops to establish if the glider is airworthy and
controllable, and following a detailed plan. Most recently, Dick
Butler and Concordia.

"Crow hops" are not advised as a way for pilots to make a transition
to different aircraft types, especially for newer and less experienced
pilots.

The OP didn't tell us what kind of glider he had bought before
starting flying lessons, only that nobody he knew had any flight
experience in type. And he had previous building experience. This
starts to smell of new pilot AND untested glider, a homebuilt or old
project that has been sitting around for many years whose
airworthiness is in question. Needless to say that is a deadly
combination.

It's an Apis 13m. Anyone with a web browser can figure that out.

You should be able to network your way to experience with the type and
develop a transition plan with an experienced CFIG. I don't see the
problem.

The Apis line of sailplanes are very easy to fly. No surprises.

The Apis I built I actually flew first time under high-tow.

Crow hops in very light sailplanes can be a handful, since they
accelerate so much faster and want to get airborne much faster than
heavier sailplanes.

Find a CFI-G to work with, get a good cockpit check out and then go
have fun. Who's did you buy?

Have one flight in an Apis 13. Very nice sailplane with an astonishing
roll rate!

Would take a high tow to get use to the sailplane.

Familiarize yourself with the proper landing and take off flaperon
positions, and you should have no problems.

Exactly. You could be the experience resource. Add a CFIG that has
managed a few pilot transitions and stir.

Proper pre-flight brief and planning, big airport, smooth air, high
tow, proper pattern, *stabilized approach*, great landing, beers and
smiles all around.

Crow hops are what you do if you have concerns about the
controllability of the glider. This is just a simple pilot transition
exercise. My $0.02.

Not the situation discussed here, but do a search for the children
gliding camps in Lithuania for a different, wonderful use of crow
hops.
