The locking mechanism on the SCOUT prop has been tested. This part is loaded with high forces due to high revolutions of the propeller.
It sustained the loading of 5000kg (yes, 5 tons or 11,000 lbs)! This is well above the forces that happen on a paramotor. We are confident that the prop is very safe to use on paramotors.
The picture above shows how the prop was attached to hydraulic machine in the lab. This test is necessary to obtain certification for use with paramotors in Czech Republic, which has one of the most strict rules in Europe. Czech certificates are accepted in Germany as well.
