We want the launching to be realistic - this includes the speed and stall behaviour during the launch, as well as the behaviour of the instruments, such as the yawstring.
X-Plane includes aerotow for gliders in the stock product. It gets you in the air behind an AI tow-plane but has limitations - the climb rate is unrealistically fast (by a factor of 4) and the tow-rope animation is very basic.
X-Plane includes winch launch for gliders in the stock product. I haven't tested this yet.
... more coming soon...
