Allinio, Peter

409 Kearney St,
El Cerrito CA.
USA

Built two biplanes, one circa 1916 and one circa 1928.

Allinio, a FAI-licensed pilot and instructor at Sunset School of Aviation in Alameda, built his first plane, a Curtiss pusher, in 1912 with skills acquired during his (as well as some of the Jacuzzi brothers’) employment by the Caproni company in Italy.

American Gyro AG-4 Crusader / Shelton Flying-Wing / Gyroplane

American Gyro Crusader NX14429

Designed by Thomas Shelton, the 1935 twin-engined AG-4 Crusader was originally called Shelton Flying-Wing and Gyroplane.

All-metal construction. Twin-boom, twin-tail empennage with a nacelle fuselage; panted wheels modified to retractable in 1936.

American Gyro Crusader NX14429

Plans sold to Timm Aircraft Co to build proposed seven-place retractable-gear AG-7, but financing problems prevented further development.

The AG-4 Crusader NX14429 was dismantled c.1941 and stored at Van Nuys CA, and was destroyed in a hangar fire.

Niviuk Jester

The 2025 Jester is perfect for soaring sessions on dunes, in strong (yet smooth) winds, dynamic descents near the terrain or proximity flights.

The risers let you adjust the angle of attack: by raising your hands, the wing accelerates and releases brake pressure simultaneously, pitching forward decisively. This turns piloting into a dynamic and fluid experience.

Whether you want to fly close to a slope, make a steep descent or indulge in coastal soaring in strong winds – the Jester offers full control.

Designed purely for fun, it turns any windy slope into your personal amusement park.

While it is designed more for descending than for gliding, in the neutral brake position it still offers some lift, making it easier to maintain control and glide.

With the Jester, we use the new Parakite System (PKS) for the risers, which connects the brakes to a pulley system that lets you adjust the angle of attack.

When you raise your hands, the wing accelerates pitchingforward and loses altitude. When you lower them, gradually slows it down by increasing the angle of attack, causing it to gain altitude. At the neutral point, the wing reaches its maximum glide performance.

Niviuk Spot

Spot 4 P

Designed for peaks. Perfect for mountaineers, trail runners and climbers who need a light, versatile wing to descend after demanding routes. Its tiny volume means it easily fits into even the smallest backpack.

The Skin 4 P is much more than an ultralight single-surface wing; it’s the ultimate evolution of hike and fly. Its design is completely new, created from scratch with a single goal: to be the lightest and most compact wing possible, without sacrificing safety or the pleasure of flying.

The Skin 4 P is an evolved version of the wing used on K2 by our pilots. Thanks to their feedback, we have improved its accessibility, in-flight behaviour, and reduced its weight, while maintaining exceptional control even at extreme altitudes.

Weighing under one kilo in the smallest size, the Skin 4 P is the lightest wing ever created by Niviuk. Every component has been redesigned to reduce weight to the absolute minimum.

Made from the new ultralight and durable N10 22 g fabric, his wing is much lighter and more compact than the previous model. The result is equipment that fits effortlessly into backpacks of less than 30 L.

During take off, the Skin 4 P inflates with surprising ease. It rises directly above the pilot without overshooting, even in light wind. It’s a formidable tool for safe launches, even in tight or technical areas.

During landing, the wing provides greater and more progressive speed retention, allowing for a more predictable, intuitive roundout and flare.

Combine your Skin 4 P with other P Series products and enjoy a complete flying kit under 1.90 kg. The ultralight Roamer 2 P harness, Expe 30 backpack, and Kase P front reserve container form a balanced, lightweight, and functional kit for your adventures.
