About Us
Culver Props was purchased in 2001 to continue offering the highest quality wooden propellers to the public. Gene and Larry Smith, owners of Valley Engineering, LLC, had used Culver Props on their own aircraft for some time and were so impressed with their performance and quality, they decided to buy the company after learning that it was ceasing production. The company and equipment were moved from Pennsylvania to Rolla, Missouri, where the manufacturing of these superior wooden propellers continues today. Special care is given to match the size and pitch of the prop to meet the customer's specific need. Each propeller is made of only the best northern hard maple and birch available, with each piece of wood being hand-selected specifically for the unit being made.
