Great app to explain how VSPs work But the physics is broken. Set Revolution slider to 3-5%, and Driving pitch to 100%, boat takes off like rocket. Same for rudder pitch, boat spins just as fast as if revolution was at 100%. Also no way to control direction of thrust.

A 4 digit NACA airfoil plotter. This app plots these airfoils and let the user watch the effect each parameter has on the shape of the airfoil. The airfoil rotates following user screen drags. A little nice tool for learning the basics of NACA airfoils shapes. This app may be usefull for airplane modeling, RC enthusiasts, wind turbine, boat, rudder designers, teachers, aerodynamics and hydrodynamics students.
