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. |

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. |

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! |

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! |

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. |

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. |

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! |

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! |

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

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. |
