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.
