 OVERVIEW
The
SUPER Sport Cub shares many airframe parts with the Sport
Cub S2 and the Carbon Cub Kit. By eliminating virtually
all airframe components that don’t carry flight or
landing loads, this modern design is simpler, lighter and
stronger than the Piper Super Cub designed in 1949. 60
years of technology has enabled CubCrafters engineers to
maximize material design and incorporate modern manufacturing
processes that maximize strength and minimize weight.
Besides
the gravity repelling 180 HP engine, the airframe design
has been tested to well beyond the requirements for Light
Sport Aircraft. Flight and landing loads were increased
by 40% to 5.65Gs for the design loads, and to 8.5Gs for
ultimate tests. Piper Super Cubs were tested to 3.8Gs as
required by the Standard Category. Struts, spars, landing
gear, control surfaces, engine mount, and the fuselage
were all tested by CubCrafters with lead weights and hydraulic
pressure, not just analyzed by computer as allowed under
LSA rules. This modern offspring of the Cub lineage is
comprised of 50% fewer parts and is 250 pounds lighter
than a similarly equipped Super Cub. With a power to weight
ratio of 7.33 pounds per horsepower, the SUPER Sport Cub
has no equal in performance!
 The
SUPER Sport Cub is available in both one and two place configurations,
and can be certified as either an S-LSA aircraft, or as an
Experimental LSA aircraft if the customer so desires.
ENGINE
CubCrafters newly certified engine is a modern upgrade of
a well-proven design that has been in use around the world
for over 50 years. The CC340 engine is certified to ASTM
2339 standards for Light Sport Aircraft. Working closely
with ECI, the CC340 engine uses electronic ignition and high
compression pistons to maximize power and economy. The engine
weighs less than 250 Lbs, and is rated at 180 HP for take-off
and climb, and 80 HP for continuous power settings. This
allows for a 2,400 hour TBO, and fuel consumption of as little
as 5 gallons per hour at cruise power settings.
Our cooling plenum seals against the back side of the cowl
inlets to force air exactly where it is needed. Light-weight
silicon seals are co-cured with the composite plenum.
The CC 340 engine is installed as part of a firewall-forward
system. Every component has been redesigned
to maximize usefulness with minimizing weight as one of the
highest goals. The complete exhaust system weighs 6.2
Lbs, or roughly half that of other 4-into-1 systems on the
market. The alternator mount is new, and because it
is closer to the center of the crankshaft, the belt is shorter
(and lighter) than in any other system we know of.
The cooling plenum ducts cold pressurized air to the oil
cooler, and provides a mount for the oil cooler that simplifies
the installation. Several pounds and several pieces
are eliminated... with great results!
Look Ma! No Mags!... or gears to drive them... If it isn't
needed, it isn't there! Carb airbox weighs just 11 Oz.
SAFETY
SUPER Sport Cubs are equipped with VGs and inertia
reel shoulder harnesses. Stall speed is a very
slow 32 MPH and the cabin is reinforced at the
shoulder harness attach points, making these points
the strongest in the airframe. The carbon fiber
seat up front is not just comfortable, but extremely
strong, protecting the pilot in all directions.
Steel tubes in the fuselage were not sized just
for flight loads, but crash loads were considered
as well. Airbags just ad to this safety advantage
and the confidence you will have when flying this
modern Cub.

PERFORMANCE
The SUPER Sport Cub is a POWERFUL airplane. It has
no equal in takeoff and landing performance, takeoff
in two or three lengths of the airplane when you
are light, and four of five at gross weight! Speaking
of performance, this plane will climb at over 2,100
feet per minute at sea level and still be climbing
at over 1,100 feet per minute at 10,000 feet. Level
off at 7,500 feet in less than 5 minutes after
takeoff! Cruise at or near the speed limit for
LSA aircraft… even with 29” tundra
tires.
This power and performance is matched only by
the SUPER Sport Cub's nimble handling and slow
speed manners. The fun factor is off the chart.
Whether flying around the patch, camping, or more
serious flying, the SUPER Sport Cub will always
deliver!
