The Piper J3 Cub is a lightweight general aviation aircraft pro-
duced in large quantities by the Piper aircraft company from
1937-1947. Designed with excellent STOL capabilities, the J-3
Cub even flew as the L-4 Grasshopper for military supply,re-
connaissance, evacuation and targeting missions.
FMS is proud to announce the brand new 1400 mm J-3 Cub
V4. Like its predecessors, FMS 1400 mm J-3 V4 retains the
excellent slow speed and STOL performance of its full-scale
counterpart.
As with the J-3 V2, the 1400mm J-3 V4 is easy to assemble,
lightweight and filled with scale details. Simple screw-together
design allow the pilot to store the aircraft with ease, while the
realistic landing gear and engine guarantees the maximum
wow-factor at the field!
Like the V3, an attractive red and white livery along with option-
al floats make the aircraft as versatile as the real thing.
The V4 introduces a highly-realistic CNC metal landing gear
that is extremely robust- guaranteed to put up with the harshest
of landings.
A traditional 4 channel aircraft, the J-3 Cub V4 is an excellent
trainer and scale aircraft all in one package- suitable for pilots
of all skill levels!
Features：
• High output power system- 3536 850KV motor paired with
a 40A Predator ESC
• Excellent scale features- engine components, landing gear
set etc
• Upgraded CNC metal shock-absorbing landing gear
• Simple screw-together assembly
• Preinstalled ball-link pushrods increases control surface
throw
• Robust and lightweight EPO material
• Optional floats
