weight of the whole propeller (2-blades here), and not only 1 blade !
WHY are the E-PROPS the world’s lightest propellers ?
1 – Because of their design
The E-PROPS team has always worked to propose very light products, because in aviation, mass is the bigger enemy.
From the beginning of the propeller design to the final finish, including all manufacturing process, every step has been thought to save weight.

2 – Because of their materials
The E-PROPS are made in carbon braid, with continue fibers between upper and lower surfaces of the blade (very high resistance). The carbon presents by far the best compromise rigidity / weight. In the composite material used by E-PROPS, the carbon is the reinforcement and the epoxy resin the matrix.
The epoxy resin is the resin preferred in aeronautics because it has very good mechanical and thermal properties, a small shrinkage in the molding, a big resistance to fatigue, a good dimensional stability and a chemical good performance, as well as an excellent adhesion on fibers.
The E-PROPS are made with only carbon braid and epoxy resin : no fiberglass, no metallic parts, no mixture of materials. Simplicity is the ultimate sophistication !
3 – Because of their manufacturing process
The E-PROPS parts are injected with the RTM process (Resin Transfer Molding), which allows to save epoxy resin, while staying very strong.

4 – Because of their finish
E-PROPS propellers are polished : it is the lightest solution and the blades are shining during their all life. They do not have a heavy gel coat layer or paint coat, as many competitors props, which shines when they are new, but which ages very quickly. A gel-coat layer can add more than 150 gr on 125 cm diameter propeller, without increasing their mechanical strength.
The E-PROPS propellers are just beautiful with their apparent carbon finish.
