The Evolution of the Challenger Aircraft
The Challenger design has stood the test of time, but it has not stood still. Over the years several hundred changes have combined to let the latest Challenger take off in less distance, climb more rapidly, and cruise 50 mph faster than the early machines.In 2005 the Bombardier-Rotax 582 Blue Head engine became the core of a new bespoke power pack which quickly replaced the 503 engine in being by far the leading choice of Challenger owners. The 582 power pack delivers 30% more horsepower and 34% more torque than its predecessor, the 503. All this with a specific fuel consumption 23% lower! The 582 power pack is now the de facto standard for floats, heavy loads, and high density altitudes.
in 2005, we increased the gross weight of the Challenger II by 20% to 960lbs.
And in 2005, we created packages including airframe, power pack, and everything
necessary for flight. The Challenger II Premium became the choice of virtually
all new owners.
newest Bombardier-Rotax 582 Mod 99 Blue Head engines are ASTM certified.
Purposely built for use in aviation they have earned top marks for reliability
as well as easy, affordable maintenance. Dual independent electronic ignition
systems fire two spark plugs per cylinder, for redundancy plus more power and
lower fuel consumption. A taller reduction drive and bigger prop increase
cruise and climb.
The current Challenger Light Sport lineup gives choices with a wide range of features; performance; and prices to suit every need and every budget!
New Challenger Light Sport ‘E’ and ‘X’ Series Models
In July 2010 the Challenger line of aircraft was expanded with the Light Sport ‘X’ Series Model XL-65. In March 2012, the line was expanded again with the new Challenger Light Sport ‘X’ Series model XS-65.
new Challenger Light Sport XL-65 and XS-65 are the most dramatic steps forward
ever taken. The XL-65 and XS-65 incorporate numerous design enhancements driven
by customer inputs. The new models are easier to fly, faster in cruise, more
rugged, more ergonomic and easier to build. Prices remain very affordable even
with engine and instruments.
The new XL-65 is a high power, high lift aircraft for amphibious floats, heavy loads, and high density altitudes. A new wing design and 582 power package with 30% more thrust combine to allow an increase in gross weight from 960 to 1060lbs. Standard 20 U.S. Gal. wing tanks allow for the creation of a baggage compartment in the fuselage behind the passenger seat.
The new XS-65 is a clip wing derivative of the XL-65 with all the same features including the 582 power pack but with a clip wing four feet shorter. The XS-65 is optimized for people who want speed. The maximum cruise speed is 100mph-lightening fast for an ultralight! The XS-65 has an impressive payload of nearly 600 lbs. With its fast cruise, long range wing tanks, and a baggage compartment in the fuselage, the SX-65 makes a great cross-country aircraft.
January 2016, the Challenger line of aircraft grew once again with the announcement
of the new light Sport ‘E’ Series Models EL-65 and ES-65. The new Challenger
Light Sport EL-65 and ES-65 provide a more attainable entry point for those
whose needs and budgets are not up to the level of the more fully featured
XL-65 and XS-65. In effect the predecessor Challenger II’s capabilities are
significantly uplifted without uplifting the cost.
configurations include faired wheels, tundra wheels, straight skies,
wheel/skies, straight floats and amphibious floats, all very affordable. In the
grand Challenger tradition of versatility switching between configurations is
quick and easy.
new Light Sport ‘E’ Series and ‘X’ Series models all retain the docile nature,
low stall speed and amazing crosswind capability of previous generation of
Challenger. The combination of outstanding STOL performance plus heavy duty
landing gear and hydraulic disc brakes allow operation from short unimproved
crisper handling to a more spacious cabin, the latest Challengers are not only
more capable and comfortable, they are better looking and quieter to boot!
This why Challenger is truly a worldwide favorite advanced ultralight!
