Our mission is to continue to produce the highest quality composite propeller for ultralight aircraft possible. We are always available to help select the correct Ultra-Prop for your application. We will not hesitate to tell you if we cannot meet your needs. Safety and customer satisfaction are our main goals. In fact, satisfaction is guaranteed. If our propeller does not work, after we have worked with you to optimize the installation, you may return it. Unless the propeller has been abused, modified or damaged, a full refund for the cost of the prop will be given.
