Piper PA-18 ou Piper Super Cub

The PA-18 has developed a very dedicated following in the bush flying community, and many modifications have been developed for it, to the point where it is quite rare to find an original, completely stock Super Cub.


Modifications include extended baggage compartments (reaching farther back into the fuselage, or even two level baggage compartments in top and bottom of rear fuselage),

external luggage pods, fuel pods, lumber racks for carrying construction materials into unimproved bush runways,

Removal of header tanks, larger 24 or even 30 gallon wing fuel tanks,

extended main landing gear for better ground clearance of the propeller,

strengthened tailwheel springs,

addition of a small third passenger seat in the luggage area, lightweight generators and starters,

various different mount areas for the battery (to move the weight forward, and reduce tail weight to shorten takeoff distance),

Various different tail feather shapes to increase surface area,

lengthened flaps,

various wingtip designs,

vortex generators on the leading edge of the wings,

movement of electrical panel from the right wing root to the dash to reduce fire hazard during a crash, and even the addition of a constant-speed propeller.

Above all, the most common modification is the addition of "bush wheels", large, soft, low pressure balloon tires designed to absorb impacts from rocks and boulders, and to not sink into sand or other soft surfaces, ideal for off-runway landings.
