| 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. |

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
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! |

| 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. |
