Inverted pitch propeller.
The APC propellers Multirotors are very successful because of its reliability, durability and quality.

Fetures:
- Made by CAD-CAM system.
- Made by injection in precision molds.
- The propeller Profile are carefully studied and they are progresive along the blade.
- Study of the correlation of static charges
- Elasticity calculated.
- Iterative design to optimize the propeller in different flight conditions.
