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

Hi Guys,

I'm curious if any of you guys have ever tried to self launch with no
wing man on a cg hook only glider. I have skids on my wingtips as
well. Would you put the wing that's on the ground further forward at
start? What's the technique!!
I think this is why having a cg hook is a disadvantage.

I've done it in my LS6 when I was aerotowed from a spasely populated
airport following a landout. It was really a no brainer.

With a CG hook, the glider has to point in the desired direction of
travel, IMHO. With a nose hook, you can angle the nose into the cross
wind (if any) and lower the upwind wing. The theory being that when the
tow plane starts, the nose hook will swing the nose straight,
accelerating the upwind (low wing) allowing it to lift level almost
immediately.

I think this is why having a cg hook is a disadvantage.

I would prefer a nose hook in this situation.

Yes, from remote fields. It's no problem, but the dust cloud from the tow
plane is sometimes pretty wild, especially if it's the first time you've
encountered it.

A CG hook is a disadvantage only if you never plan to winch launch.

I was shown at rig made with PVC plumbing pipe for just such a situation.
it worked like a saw horse with a carpeted top and could be broken down for
storage in the glider trailer. Starting with the wings close to level is a
big help.

I don't think I would try a CG hook, wing-on-the-ground start with my Nimbus

Have done it in my Nimbus 3 and many times in my Pegasus, both CG hooks.

I too have done it in an LS6 - We just lined it up and went - powerful
towplane helps.

But we used to practice it in a 2-22. There was a very specific technique
and it was not self-evident. As I recall, the upwind wing was down but the
nose pointed downwind (!). This allowed for weathervaning which would
effect the a/c before the controls became effective. It worked pretty well.
Of course, the 2-22 sits on it's nose rather than it's tail.

So why would you point an unguided rocket downwind in order to have it reach
apogee directly over the launcher?

Aerotow no problem. Don't try it with a winch though!

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.
