Simple and small sailboat for winds between 10 and 20 mph. This improved version is mostly more controlable than the first one. The dead weight is realy heavy so you shouldn't just go all in at the beginning.

Controls

Rol and triml: Steering (rudder)
Throttle: Sail
VTOL: Dead weight that's 'alive' to left and right

To start

10 mph wind is the easiest and I propose you start with that. When you start just loose your sail to 50-100% and wait until you've made some speed. Then turn the dead weight to the hight side and pull your sail in. You can turn the control of the main sail to pitch if you want to try it with the joystick. It takes some practice but the joystick-function makes it really fun.
