CHALLENGER II CLIPPED WING SPECS |
Wing Span
(opt Fiberglass
- std Bow tips) |
The span of the long wing can be
reduced 2 feet by replacing the standard bow wingtips
with the new optional fiberglass tips, thus increasing
roll rate and cruise speeds.
The
shorter span of the clipped wing gives still higher
speeds and faster roll rates plus a more aggressive,
sportier feel. |

Wing Area
(opt Fiberglass
- std Bow tips) |
A low empty weight and a very large
wing with a 5.625 foot chord are the keys to the
impressive carrying capacity of the Challenger. The long
wing has 40-70% more lifting surface than competitive
designs. Even the clip wing has 20-40% more area. More
lift means less horsepower is required to achieve goals. |

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 of them! |

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

Empty Weight |
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. A low weight benefits all aspects of
performance. Most competitive aircraft are 100-200
pounds heavier! |

Payload
(at indicated
Load Factor) |
The payload figures are based on
static testing to the ultimate load factors given below.
Greater loads can be carried with reduced load factors. |

Load Factor
(Ultimate) |
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
completely built in jigs at the factory. |

Fuel Capacity |
The Challenger factory offers a 10
US gallon fuel tank and a 15 US gallon long range fuel
tank is available from a Canadian company. |

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! |

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 tailor to
you! |

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
increased knee room. |
