Bamboo Copter Toy variable Angle of attack by blindsider

Last crawled date: 4 years, 8 months ago

This is a Bamboo Copter designed in Open SCAD, where you can choose the angle of attack. The purpose of this is to show in physics class that aerodynamic lift increases with increasing angle of attack.
In this regard it works really well. The design is such that the Copter blades can be printed, while the stem is one single chopstick.
For playing, an angle of attack of 15° works well.
