The E-flite 4-Site 3D FF (Flat Foamy) 800mm revives the unique capabilities of classic flat foam models without any of the building hassles. It's a modern, convenient biplane alternative to the popular Eratix 3D FF, perfect for intermediate pilots looking to get into 3D flying or for experienced pilots wanting a quick and easy addition to their hangar. Unlike traditional foamy kits that require hours of gluing and taping, the 4-Site 3D FF bolts and snaps together in less time than it takes to charge a battery. It arrives mostly factory-assembled with a powerful 3S-compatible brushless motor, a Spektrum Avian 30A Smart Lite ESC, and three precise, digital metal-geared servos already installed, taking all the guesswork out of the setup.

This model is designed for a true "mild to wild" flight experience. The biplane configuration provides a lower wing loading, making it an excellent platform for everything from slow, stable flight to all-out aggressive 3D aerobatics. The extremely durable yet lightweight EPP airframe is reinforced with carbon fibre for added stiffness. This BNF Basic version includes a Spektrum AR630+ receiver featuring enhanced AS3X+ technology for an incredibly locked-in feel, plus optional-use SAFE Select to provide flight envelope protection for added confidence. The aircraft is versatile enough to be flown indoors in gymnasiums or outdoors in backyards, parks, and sports fields, making the 4-Site 3D FF a fantastic and easy-to-fly biplane foamy for a wide range of pilots.

Enhanced Stability with AS3X+ and SAFE Select

Experience an incredibly locked-in feel with enhanced Spektrum™ AS3X+ technology, which smooths out wind and turbulence even better than before. Optional SAFE® Select offers bank limits and self-levelling for extra confidence. Plus, a Smart Model File automatically loads settings for NX/iX transmitters, getting you flying faster than ever.

Real-Time Telemetry with Spektrum™ Smart Technology

Keep tabs on your power system in real-time. The exclusive Spektrum™ Avian™ Smart Lite ESC provides live telemetry data, including motor RPM, current, and battery voltage, to your compatible transmitter. This works with both Smart and non-Smart batteries, giving you vital information to manage your flight effectively and safely.

"Mild to Wild" Flight for Any Style

Enjoy incredible versatility with a plane that does it all. The 4-Site 3D FF is capable of slow cruising, smooth sport flying, and even aggressive 3D aerobatics, all in the same flight. It’s perfect for intermediate to experienced pilots looking for a "mild to wild" experience indoors or outdoors.

High-Performance 3D Brushless Power System

Unleash unlimited 3D performance! The factory-installed brushless power system features a specially tuned Spektrum™ out-runner motor. Paired with a 3S 850–1000mAh battery, this setup delivers an abundance of thrust for hovering, harriers, and unlimited vertical climbs, giving you all the power you need for aggressive aerobatics.

Quick, Glue-Free Assembly Gets You Flying Fast

Unlike typical foamy kits, the 4-Site 3D FF arrives mostly factory-assembled, with the power system and servos pre-installed. Final assembly is a quick and easy bolt/snap-together process that requires no glue, tape, or special tools. You'll be ready to fly in less time than it takes to charge a battery!

Lightweight, Durable, and Stiff EPP Construction

This flat foamy is built to handle aggressive flying. The airframe is constructed from carbon fibre and composite-reinforced, high-density EPP, making it lightweight, stiff, and durable. Three factory-installed digital, metal-geared servos provide precise and reliable control. Plus, a full line of spare parts is available if needed.
