Overview

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.
