Mount twin tow hooks on the fuselage sides, just under the wing root at the CG. Use a bridle that has a ring on each end and runs freely through the ring on the end of the tow line. A big, heavy scale ship like this is best winch launched from the ground. Have an assistant hold on to one of the wing tips to level the wings untill it is airborne.

Tow Hook location...
Thanks so much... the bridal really makes more sense
than a single hook -
I'm flying 40% aerobatic planes now but the thought of launching this
gives me more "jitters" than a first flight with a 150 cc motor!
I appreciate the help - lots.

I don't know how large your ASW-19 is but I launch a lot of them up to 4.5 meters without any problems. My DG 800S weighs 6.5 kilos and is no sweat!
A bridle greatly simplifies things and the hooks should be about half way bewteen the CG and the leading edge, fairly low down on the fuselage. A "Y" tow line about 1-1.5 meters long is connected up and away you go.
I strongly recommened against having anyone hold the wings during launch! Simply level them out with one foot under a wing and that is it. Trying to run with the plane will generally end up holding back one tip and starting a yaw circus. A sailplane will be aileron controllable right from the start so keeping the wings level is not a problem.
If you do not use the bridle, then position the hook about 3-4 cm in front of the usual position. This will make the plane less apt to nose up and stall right after take off.
Have fun,
Gary
