Featuring a Poly-V belt and gear reduction ratio of 3:1, this design is tailored for use in microlight planes alongside Briggs & Stratton Vanguard engines. Key features include no bending loads on the crankshaft, an extra mounting point for propeller loads to avoid engine housing stress, adjustable belt tension without moving the propeller hub, and compatibility with standard Rotax propeller hubs, all mounted securely with 4 bolts up front.
