WhirlWind’s GA blades are constructed from aerospace thermo-set composite materials, and are equipped with a full length electro-formed nickel leading edge for unparalleled durability and precise fit. These blades are light and durable, and are suitable for flying in rain and from unimproved airstrips. Optimized planform shape and proprietary airfoils make this propeller efficient and very quiet in operation. The carbon fiber construction with X-Core™ ensures a safe, strong propeller with low inertia. The Nickel leading edge provides superior abrasion protection and the blade’s high gloss natural carbon fiber finish will satisfy the most discriminating owner. WhirlWind’s GA hubs are machined from aerospace grade billet aluminum.
