Design

Three factory-installed digital servos with metal gears on all the control surfaces, plus construction with carbon fiber and composite-reinforced, high-density EPP, deliver a lightweight yet stiff and durable airframe. This rigid biplane ensures that, during high-G maneuvers, the airframe does not flex, ensuring you can stay in control.

Capabilities

Like other flat foamy models, the 4-Site 3D FF is capable of slow cruising, smooth sport flying, basic aerobatics, and even aggressive 3D flying—all in the same flight! Dual aileron control surfaces allow this plane to snap on demand while also allowing for smooth performance in low rates, offering a true "mild-to-wild" experience.

Advanced Electronics

The factory-installed brushless power system features a specially tuned Spektrum outrunner motor. This power system delivers plenty of thrust for unlimited vertical and 3D performance with 3S 850–1000mAh batteries! The included Spektrum AR630+ receiver allows for advanced telemetry data right to your compatible Spektrum Transmitter.
