The function of an anti-shock system is to absorb the variation in kinetic energy that is generated with an impact (in a propeller when the gears are engaged or in the event of an accidental impact). We can define the “damping path” as the space available between the start of the impact and the final stop. The greater the damping path (in this case angle), the greater the anti-shock effect.

Almost of all the anti-shock systems currently available on the market consist of the insertion of simple hard rubber or plastic shims into the propeller, which allow a damping angle on average not exceeding one/two degrees.
The Max Prop® Antishock propeller is an Easy model propeller equipped with a patented elastic device in special steel which allows a damping angle greater than 25 degrees. Therefore, the Max Prop® Antishock propeller is the only one that allows a real shock-absorbing effect.
