Typical Challenger II 503 Deluxe Package

Wing Span

The span of the long wing can be reduced 2 feet by replacing the standard bow wingtips with optional fiberglass tips, thus increasing cruise speed and roll rate plus giving a more sporty feel. The shorter span of the clip wing gives still higher speeds and faster roll rates. The long wing is best for floats and soaring. 31.5 ft
(Std Tips)

29.5 ft
(Fibreglass)
26.0 ft

Wing Area

A very large wing with a 5.625 ft chord and a low empty weight are the keys to the impressive carrying capacity of the Challenger. Payloads of 500 lbs are typically carried - more than its own weight! The Challenger's wing area is 40-70% greater than competitors! More lift means less horsepower and that means less cost. 177 sqft
(Std Tips)

166 sqft

Length

The fuselage fits nicely in most garages, making that a popular place for assembling Challenger kits. The wings fit easily too because there are two 15 ft wings rather than one giant one and they don't have to be installed until you're at the airfield for the first flight! 20 ft 20 ft

Height

Puddlejumper amphibious floats add 20" to the height on the ground. Skis add an inch or two. 6 ft 6 ft

Typical Payload

A very light airframe, built by the factory using triangulated 6061-T6 aircraft-grade aluminum, is the secret to the Challenger's unusually low weight and high payload. A low weight benefits all aspects of performance, not just payload but also takeoff, climb, cruise and landing. The Challenger is 100 to 200 lbs lighter than competitive aircraft! 500+ lbs 500+ lbs

Load Factors

The Challenger employs a fully triangulated truss design which is not just lighter but is significantly stronger than alternatives. Since construction of such a design is beyond the capabilities of most homebuilders, every Challenger airframe is built in jigs at the factory. This ensures consistent quality and integrity of critical components. 960 lbs 960 lbs

Fuel Capacity

Our Canadian Challenger's standard fuel tank is 10 US gallons. An optional tank holding 17 US gallons provides greater endurance and range. 10, 17

Seats

The Challenger uses tandem seating rather than side-by-side to achieve less drag for higher speed as well as to place the pilot ahead of the wing for magnificent helicopter style visibility in all directions - even in turns. Tandem seating with doors on both sides makes docking on floats a snap. Most tandem ultralights only have one door - what do they do when the wind forces docking on the other side? They can only go elsewhere, unless they want to swim around! 2 2

Cabin Width

Two cabin sizes are available: a wide body with low cockpit side rails and a narrow body with high sides. The wide body is easier to enter and exit. The narrow body has a tad less drag. Compare to the Cessna 172 cabin with only 39.5" for two people across! Wide Body

Head Room

The Challenger is famous for it's spaciousness - it was designed by a big guy for big guys and over the years it has gotten even bigger. And we do mean big! 6' 5"? No Problem! 6' 7"? Call us - we can tailormake your Challenger to you! Front

Leg Room

While we do suggest you leave your stilts at home, even those long in the leg will fit comfortably in recent model Challengers. Redesigned seats and supports add all important inches front and back and give passengers additional footrests and more knee room. Front
