To work on the defintion on a propeller, please consult the MODELIZATION PROGRAM

 

The E-PROPS PROPELLERS exist for engines from 15 to 300 hp, in diameters minimum 1,15 m / 45 inch to maximum 3 m / 118 inch.

Our manufacturing process does not allow us to make propellers with smaller or bigger diameters.

Please note that our team will not answer to requests concerning smaller or bigger propellers.
