The first series of ASW-15 was delivered with only a center of gravity hook. This hook is placed left of the midline of the plane. This situation causes the plane to go left in tow or winch launch. The latter ASW-15's had also a towhook. This tow hook is also available at Schleicher as a modification kit.

So what to do to avoid the tendacy to make a dangerous groundloop and anticipate to it. Note this situation only takes place at take off when there is still ground contact.

• Get briefed by experienced pilot's at the ASW15
• Is the tail skid installed so it is in line with the fuselage?
• Start every tow launch with the stick fully back. This keeps the tail firmly planted while on initial roll and helps to keep directional control. Once aileron control is felt, release the backpressure and allow the glider to rotate up onto the main wheel. Remember, this all happens well before the glider flies. I would not suggest keeping full back pressure, you might find your aerotow looking more like a winch launch.
• Keep always your left hand near the release.
• Brief your wing runner very well and always have them run your downwind wing. It’s a hell of a lot easier to slightly hold back than to run forward to keep you straight in a cross wind.
• If you have any cross wind make sure you start with FULL opposite rudder to counter any swing at towlaunch.
• At winch launch always start with full left rudder, you're too late to react when the plane wants to break out. After a few seconds you can give less rudder.

Don't get frightened by all of this, it's still a fine plane to fly. Many safe landings AND starts ;-) These tips are collected at the internet and I want to thank all the pilots for their tips but especially member Wyvern for his help.
