We made a complete transport trailer; you can see it he

The lateral arms could be lowered and raised, and the platform could
be inclined until the back was resting on the ground, without
unhitching the trailer. A hand-powered winch towed the glider up the
incline.

It worked well, even too well: once upon a time, a driver forgot he
was towing, drove too fast, and the Blanik began flying at the end of
the very short winch cable. It was damaged when coming down... It
could be used for all the gliders of our club fleet.

It was sold when we went for 100% plastic.
