ULTRA-LIGHT CARBON PROPELLERS for DRONES & UAV
E-Props : manufacturing, leading edge protection, balancing, tracking
E-PROPS propellers are manufactured entirely in France (South-East, Provence, near Sisteron).
The team of 53 aeronautical engineers and technicians produces over 75000 carbon blades a year.
1- E-Props manufacturing process
2- Leading edge protection : Titanium or Nanostrength
3- Propellers balancing
4- Tracking
5- Propellers and vibrations
All E-PROPS parts - blades, hubs and spinners - are made of carbon + epoxy resin.
They are manufactured using a process known as RTM (Resin Transfer Molding).

E-PROPS offers two solutions for reinforcing its carbon blades:
- Titanium leading edge protection (V20 propeller range)
=> See description here: TITANIUM LEADING EDGE PROTECTION
- Nanostrength impact additive reinforcement (V12 propeller range - no longer in production since 2019 - and fixed-pitch propeller range)
=> See description here: NANOSTRENGTH LEADING EDGE PROTECTION
E-PROPS Titanium leading edge protection
E-Props are renowned for their light weight, low moment of inertia and perfect balance. They all leave our workshops perfectly balanced. At E-Props, each set of blades is balanced with its own hub and spacer.
Note: in a propeller, the blades don't necessarily have to have the same mass. If your blades don't have the same mass, it doesn't matter. What counts for perfect balancing is the distribution of mass along the length of the blade, i.e. the static moment.
=> See explanations here: E-PROPS BALANCING
"Tracking" is the difference in longitudinal position from one tip to the next.
On E-PROPS, the maximum tracking tolerance is 15 mm.
=> See details here: E-PROPS TRACKING
E-Props max tracking
E-Props propellers are known for generating very little vibration, because they are very light, and all balanced on a dynamic electronic bench. The E-Props team devotes a great deal of time to this operation, and balancing tolerances on both new and repaired propellers are extremely low.
However, pilots may occasionally experience vibrations during flight. These may originate from the propeller, the engine and/or the aircraft.
