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
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.
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.
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!
