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.


  • Powerful 3536-850KV motor, Predator 40A ESC
  • Highly detailed scale engine and landing gear
  • Simple structure for quick assembly
  • Durable EPO material
  • Optional scale floats


Like its full-sized counterpart, the all-new FMS 1400mm J-3 V4 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 V4 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 lines from the golden-age of flight- the 1400mm FMS J-3 V4 is all of that, and more.

FMS Reflex V2


Complete System Upgrade - Reflex V2 is Compatible with Most FMS Aircraft

The Reflex V2 is a user-upgradeable flight controller. Reflex V2 can be reprogrammed easily with different model files via a simple software - allowing pilots to use the same flight control unit as they progress to different aircraft. Flying is simple when you have your very own “co-pilot” — the Reflex V2!

Reflex Functions

Three flight modes are available: Stabilized, Optimized or Off. This is controlled with a two or three position switch on the transmitter. When assigned to a two position switch, the Reflex system changes between stabilized and optimized modes.

Stabilized mode: Designed for beginners, Reflex will rapidly level the aircraft from any attitude when this mode is activated. Stabilized mode combines accelerometer and gyro data to determine how to level the aircraft when the control sticks are released - giving pilots absolute peace of mind. Note: The aircraft will maintain level flight with 50-60% throttle, and the aircraft will climb under full throttle.

Optimized mode: Utilizing advanced solid-state gyros, the Reflex system maintains aircraft attitude by counteracting inflight upsets - for gusts to crosswinds. With Reflex, even small aircraft will fly with the confidence of something much larger!

Off: Turns off all gyro functionality, the aircraft is flown completely manually when the gyro is off.
