But, as expected, the lighter composite blades lacked the stiffness (flexural modulus) of aluminum. To accommodate the bending that would occur under load, subsequent blades were overdesigned in terms ...

Props for your little RC airplane or drone are effectively consumables. They’re made of plastic, they’re cheap, and you’re going to break a lot of them. When you start swinging so… ...

The carbon-fiber composite propeller is now available for Cessna 180, 182, 185, 206, and T206 single-engine aircraft equipped with Continental 470-50, 520, and 550 engines. The propellers come in ...

The Polaris is a 74-inch diameter, three-blade ASCII carbon fiber prop for the Austro Engine E4-A. It features a lightweight Bantam aluminum hub and 2,400-hour/six-year TBO, with Hartzell’s ...

The 91-inch diameter, five-blade swept airfoil carbon fiber propeller uses derivative blades, hub and retention components from an existing 14 CFR Part 35 certified propeller. The specially designed ...

While time between overhauls for carbon-fiber and aluminum propellers is typically the same, composites have the advantage of being restored to factory-new shape between overhauls.

It's also reportedly easier to repair and transport (thanks to its folding carbon fiber prop arms) and has a longer flight time of 25 minutes per charge, if the recommended dual 6,500-mAh lithium ...
