Description
Our popular and highly efficient endplate design is now available for the APR GTC-300 series Competition Airfoil, customized to work with the APR variable chord 3D shape. Please note that the APR GTC-300 has a slightly different wing tip profile in the 61 inch and 67 inch sizes, and this model is designed to work with the 67 inch wing. Made from lightweight .063/.080 5052 aluminum, our CFD-tested endplates are designed to improve the performance of your existing APR GTC-300 airfoil. Available in both low drag, standard and high downforce configurations. In the low drag configuration, the lower portion of the endplate is straight to allow for the gradual mixing of high and low pressure flows to reduce drag over a rectangular endplate of comparable area by as much as 10%. The high downforce bend incorporates the pressure relief slots above the wing for improved underwing efficiency, while also adding a vertical Gurney flap to increase the underwing suction and maximize low pressure flow under the foil. Both versions offer reduced drag over commonly used rectangular endplates. Please allow 2 weeks for laser cutting, fabrication and coating + 3-5 days for UPS Ground shipments.
