4-Site 3D Flat Foamy 800mm BNF Basic (EFL02950)

The E-flite 4-Site 3D FF Flat Foamy 800mm BNF Basic is a compact, high-visibility biplane designed for aggressive aerobatics and 3D flying in a lightweight, durable foam airframe. With an 800mm wingspan and a rugged EPP structure reinforced with carbon fiber and composites, it performs indoors in gymnasiums or outdoors on parks and fields. The BNF Basic version arrives mostly factory-assembled with the power system, servos, and receiver installed, so it’s ready to fly in less time than it takes to charge a battery.

Power comes from a 3S brushless motor paired with a Spektrum Avian Smart Lite ESC, and the AR630+ receiver delivers AS3X+ stabilization with optional SAFE Select for added pitch and bank limits. Three factory-installed metal-geared servos handle precise control, and a high-contrast trim scheme helps with orientation. The landing gear snaps into place for easy installation and replacement, and the bolt-and-snap assembly requires no glue or tape. Built for pilots with some experience, the 4-Site 3D FF offers a versatile flight envelope—from slow, smooth sport flying to aggressive 3D maneuvers—whether flown indoors or outdoors.
