Is it Possible to Self launch (no wingman) with CG hook??

Why not? Winch is easier than aerotow: The rapid acceleration
means you have instant roll-axis control.

(done it several times, easy as pie)

Instant roll control and no prop wash to deal with.

There was a 'lone ranger' who built a remote controlled winch 20 or 30 years
ago. He could launch himself with no help at all. I'd like to know more
about that winch.

Actually, the prop wash will help, by providing some airflow
over the wings and control surfaces, giving you a certain
degree of control, even before the speed builds up.

Actually, I'd contend this causes most wing drops since it's usually not
evenly distributed over both wings.

We're talking about a winch, CV. You don't have to wait until the speed
builds up :-)

You need to be "very very" quick on release if the down wing
does not move forward with the winch launch as the upper wing
starts flying and lifts up and can throw the glider/you into an
end over end cartwheel, fatalities have happened with that scenario.
The winch rapid acceleration is a two edged sword ,as long as
you get the wings both moving forward its easier than a aerotow
wingdown takeoff.

You don't start with a "down wing". You prop the wings so
they're level.

I always start with a "down wing" when being alone. No problem whatsoever.

The point is this "cartwheel scenario" has happened before.
I believe there was a case in Europe not that long ago.

Indeed!

If a wing tip catches on something like tall grass, the combination of high
acceleration and CG hook can be disastrous. This sometimes results in a
flick roll and inverted crash. This is why the takeoff area of winch
operations needs to be smooth and the pilots 'spring loaded' to release if
the takeoff roll swerves.

If the takeoff surface was smooth asphalt and the glider had tip wheels or
low-friction skids then starting with a wingtip propped up on a stand or box
might not be so dangerous. It pays to be careful though.

Let me add just how sweet it is to accelerate and lift off without the
turbulence, noise and dust of a tow plane. Compared to air tow, a winch
launch area is downright civilized.
