The Dualsky DFP Classic folding propellers feature an independently developed airfoil for excellent efficiency and are optimized for use with the Dualsky FPS-Z spinner assemblies. Thanks to more advanced manufacturing processes and a stronger Carbon Fiber Nylon composite construction, weight is reduced by over 20% compared to props of similar size classes while retaining their high strength, making them excellent choices for F5B, F5J, F5K and eRES.
