The company is known for selecting the best-performing OEM and Aftermarket stainless steel propellers in the industry that fall into a specific category due to a new prop for that category. At the same time, using the identical geometry and drawing, a superior aluminum and stainless steel variant is created. The design is refined by firm engineers through testing until it outperforms competitively priced Stainless Steel props. The 14X21 S4R PROP (5389-4140-21) is far more durable than aluminum. Significantly superior to aluminum propellers in terms of performance. Higher performance than OEM and aftermarket Stainless Steel props is expected.
