The propeller showen in the photograph has been custom built from solid Mahogany for the world's only airworthy Spartan II three seat biplane. It is entirely hand made and features a full length brass leading edge. The performance is reported to be significantly better than the original. If you have a special project, we would love to help. Unfortunately we can not supply custom made propellers for certified aircraft. The price is subject to change depending on your exact requirements.
