8" propeller

8 inch propeller designed for some aerodynamic tests.

Helds up well up to 5000 rpm (producing just above 1N / 100gr of thrust).
At about 8000-8500 rpm it becomes unstable if it is not dynamicly balanced. It produces 3-4N / 300-400 gr of thrust. (with an ABS print there was only elastic deformation)

But please make sure to use it responsibly and with sfety in mind as any other printed item that youi turn with high speeds.
