All our products are Made in Italy — designed, built and assembled by us. Attention to detail is our strength.
Built on the Fly Products Rider platform — the most versatile PPG frame available today. It mounts to multiple trikes, from the Foxy mini trike to the larger Flash Trike (which also allows tandem flights) and the super-stable single-seat Vertigo Trike, and suits every level of pilot, from beginner to world champion.
Constructed of aluminium with self-tempering welds for the best possible weight-to-strength ratio. Our ASC distance bars are tested to 1,800 kg each and adjust to fit every pilot from XS to XXL. The harness is lightweight, durable PVC with emergency releases that open under tension, adjustable in every part and available in Narrow and Wide sizes. Our “React” throttle keeps the shutdown button accessible but protected from accidental knocks, with a built-in fuel-range mirror.
The Rider cage fits single- and double-hoop configurations for 125, 130 and 140 cm propellers, so you can start on the safer double-hoop cage and later switch to the lighter, better-performing single-hoop model.
