Introduction
The Piper J-3 Cub is an American light aircraft that was built
between 1937 and 1947 By the Piper Aircraft Company as an
affordable trainer. The aircraft has a simple, lightweight design
which gives it good low-speed handling properties and short-
field performance. During the WWII, J-3 Cub was designated as
L-4 Grasshopper, used extensively for reconnaissance,
transporting supplies, artillery spotting duties and medical
evacuation of wounded soldiers.
Like its full-sized counterpart, the all-new FMS 1400mm J-3 V3
has excellent short takeoff and landing (STOL) and slow speed
handling characteristics. FMS has dedicated significant amount
of resources in making this aircraft as detailed as possible-
components such as the engine and landing gear, among many
others, are replicated in loving detail. Something worth noting is
that FMS has made scale floats for the Cub as a response to
popular demand from the community.
To mix things up a little, FMS has selected an attractive,
historically accurate red paint scheme for the V3 Cub. Not all
J-3’s were yellow!
For pilots who are looking for an easy-to-fly, scale aircraft that
has gentle trainer characteristics, plenty of power and graceful l
ines from the golden-age of flight- the 1400mm FMS J-3 V3 is
all of that, and more.
