XOAR 21x8 Beechwood PropellerXOAR (Z'OAR) Propellers are rapidly becoming the most popular propeller choice with 3D and IMAC flyers. XOAR offers greater thrust with lower noise. Made from beautiful imported French beechwood, each prop is digitally machined for correct pitch and blade cross-section, then hand worked by experienced technicians to assure the best aerodynamic performance. Every XOAR propeller offers excellent static and dynamic balance through controlled symmetry, weight, angle, diameter and width which minimizes active vibration. Each propeller is pre-treated and finished with a hard satin finish.
