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! |

| 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! |

Gross Weight
(+6G / -3G Ultimate 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 completely built in
jigs at the factory. |

| Fuel Capacity |
Canadian Challengers
are equipped with a
10 US gallon fuel tank. 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!

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. |
