Based on wind-tunnel tests on various homebuilt aircraft, these vortex generators were designed for peak effectiveness in decreasing stall speed, improving climb, and reducing take-off and landing distances. Their twin tip design includes the optimum shape and angles required, thereby allowing you to install them by simply spacing them out in a straight line on a wing or horizontal stabilizer. Kits include 46 curved & 16 flat vortex generators, tape for trial mounting, adhesive for permanent mounting, and complete instructions. Made of .025 6061-T6 aluminum. For experimental, LSA & Ultralights only.
