Challenger II Specifications

Long
Wing
Clip
Wing
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 (with either standard or fibreglass tips) is best for floats and soaring. 31.5 feet

Wing Area
(opt Fiberglass
- std Bow tips)
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 feet2

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 feet 20 feet
Height Puddlejumper amphibious floats add 20" to the height on the ground. Skis add an inch or two. 6 feet 6 feet
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 somewhat less drag. Compare with the Cessna 172 cabin with only 39.5" for two people across!

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 have the factory tailor make 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
