Wills Wings – Falcon Hang Glider – Intermediate Soaring


Falcon 4

The Falcon 4 represents twenty years of cumulative refinement of the most popular and successful glider in Wills Wing’s history. Since 1994, the Falcon series of gliders have represented the most accessible, stress-free soaring performance available in hang gliding, and have helped to introduce an entire generation of new pilots to the sport.

What’s New

Updates on the Falcon 4 include a new sail cut and new sail panel layout, improved lateral stability at higher speeds and under aero tow conditions, and the option for the glider to be built with a Litestream Control bar for an extra $275. The Falcon 4 comes standard with an airframe that breaks down to shipping length, but is not short-packable into the 2-meter length. A short-packable airframe is an available option on the Falcon 4 for an extra $250. The 195 size features an extra batten for improved airfoil definition, and, on the standard airframe, a smaller diameter crossbar for reduced drag and improved performance. The Falcon 4 is currently available in the 145, 170 and 195 sizes

Falcon 4 Performance

Less than ten days after the first production Falcon 3’s left the factory, a demo Falcon 3 170 had been flown 205 miles by Davis Straub for a new single surface cross-country world distance record. The Falcon 4 carries forward the tradition of exceptional effective soaring performance of the Falcon line, by providing an unmatched combination of relaxed and responsive handling with exceptional climb rate and low-speed glide. For developing pilots, this is a glider that will allow you to have longer flights more often, and as a result, will help you improve your flying skills more rapidly. For experienced pilots, the Falcon 4 will remind you of just how simple and how enjoyable soaring flight can be.

Control Bar

The standard control bar on the Falcon 4 features round downtubes and a round, speedbar (comfort bar) basetube. (Note that these control bars are the same as the Falcon 3 control bars, but are different from, and not interchangeable with AT type control bar used on Falcon 1’s and Falcon 2’s – see the article Falcon Control Bars Not Interchangeable for more information.) This control bar configuration will accept either the 5 inch diameter Hall wheels or the 8 inch diameter Finsterwalder wheels, mounted directly on the basetube. As an option, Falcon 4 owners can order their glider built with the Litestream Control bar – equipped with either a streamlined or round speedbar basetube. The Litestream control bar with the streamlined basetube will accept the Wills Wing Streamlined Wheel Kit as an additional option, and with the round basetube, you can use either the Hall or Finsterwalder wheels.

Sail Colors

All panels in the Falcon 4 sail are available for use of coloured V170 4 oz. woven sailcloth. Inventory gliders will have factory selected colours on Panel 1 (top surface leading edge) and Panel 5 (bottom surface), and customers can select their own colours for these panels, as well as for panel 4 (trailing edge), without any extra charge for colour choice.  In addition, colour choices can be selected for Panel 2 (top surface immediately behind Panel 1) and Panel 3 (mid-chord panel) for an additional $75 per (full span) panel.

Sail Materials

All panels in the Falcon sail will be made normally with 4 oz woven sailcloth. 205 MT can be selected for panel 1 (leading edge) and / or panel 4 (trailing edge) for an extra charge (see options table). Finally, UVPXB05 can be selected for panels 1, 2, 3 and 4 for an extra charge. All of these options require the customer color choice option charge as well.

Optional Falcon 4 Short Pack Airframe and Deluxe Transport / Storage Container

The Falcon 4 with the optional short-packable airframe can be broken down to a short pack length of seven feet (195), six and a half feet (170), or six feet (145) for transport, shipping or storage. Wills Wing offers an optional protective container, specially designed to provide maximum protection and transport convenience for your Falcon 4. The overall dimensions of the container allow you to check the glider as baggage on most airline flights.

The Deluxe Transport / Storage Container consists of a protective dense foam liner inside of a heavy-duty, ballistic cloth zippered bag. The entire glider – sail, airframe, battens and cover bags – fits inside the container. The ballistic outer bag and foam liner provide damage protection for the sail and airframe.

Mark Stucky aka “Forger”

Yesterday I flew Walt’s for the first time in 20 years. The Falcon 4 FR [Full Race] caught a lot of stares and a few questions on launch. It was a strange day with light SE flow up to around 10K’ and then NW above, the shear making for ratty thermals with 800 fpm up for 2/3 of the turn and 100 down for the last part, requiring continuous corrections.

Since I could rarely get above 11K’ I was forced to fly well in front of the main spine. The Sierras were clouding up pretty quickly so I made the decision to try to make the big crossing at Independence. The Falcon enabled me to drift lazily in little bubbles and dive for extended periods without the tiring bar pressure that I was used to on the previous glider that I owned.

I made it up on the Inyos and flew on to just past Westgard Pass so that I could tag the 50 mile mark before returning to a nice field for landing next to my chase. I smiled when we drove south past the Lone Pine airport and I saw a good half dozen double surface wings breaking down.

In the past, I’ve suffered from finger cramps due to high bar pressures and cold temps. I used convertible mittens with the carbon base tube and was comfy the entire time. I really like how the bar has grips oriented for turning flight as well as for getting pointy when you’re trying to maximize the glide.

When I flew for long periods before I had sore arms, shoulders, and lower back. With the Falcon the only thing sore was my neck from holding my head up for so long!

I love my Falcon!
