The Golden Age of Aviation brought us the teardrop-shaped Gee Bee, a racer known for blistering speed but notoriously difficult handling. Now you can own a piece of history with the E-flite UMX Gee Bee R-2, an ultra-micro replica that successfully tames the beast. Unlike the full-sized original, this model is a joy to fly thanks to exclusive AS3X and optional SAFE Select technologies. These innovative systems work behind the scenes to smooth out wind and turbulence, giving you the locked-in feel of a much larger aircraft while allowing you to fly in smaller parks, sports fields, or large yards.
This updated version is not just about control; it is about raw performance and durability. It features a strengthened airframe and a new brushless motor compatible with both 2S and 3S LiPo batteries. Fly it on 2S for a classic sport feel, or switch to 3S for unlimited vertical performance and blazing speed. The model arrives 100% factory-assembled with a telemetry-capable control unit, meaning you can be airborne in the time it takes to charge a battery. Constructed from lightweight EPS foam, it is rigid enough for high-speed manoeuvres yet easy to repair. It is the most accessible and fun way to experience this unique racing legend without the stress.
Spektrum AS3X technology works behind the scenes to smooth out wind and turbulence, providing a locked-in feel. Optional SAFE Select offers pitch and bank angle limits alongside automatic self-levelling. These exclusive features make this 510mm (20.08") model easy to fly, delivering the stability and precision usually found in much larger aerobatic aircraft.
Get into the air quickly with this Bind-N-Fly (BNF) completion level. The aircraft arrives with the power system, servos, and a Spektrum 2.4GHz receiver factory-installed. Simply bind it to your compatible DSMX/DSM2 transmitter and finish minor final assembly. You will be ready to fly within minutes of opening the box, ensuring a high-quality control experience.
The factory-installed brushless out-runner motor is compatible with both 2S and 3S batteries. Use 2S 280-300mAh packs for standard flight or upgrade to 3S 300mAh for unlimited vertical performance and significantly higher speeds. This quiet yet powerful system ensures your 510mm (20.08") Gee Bee R-2 handles technical 3D manoeuvres with incredible authority.
Stay informed with real-time flight battery voltage telemetry sent directly to your compatible Spektrum AirWare-equipped transmitter. The integrated flight controller and ESC provide vital power data while you fly, allowing you to monitor your battery levels accurately. This ensures you can manage your flight times without the need for additional sensors or complex wiring setups.
This model features a true-to-scale outline enhanced by functional flying wires, a clear canopy, and a detailed pilot figure. These scale touches provide a premium appearance on the ground and in the air, making your 510mm (20.08") UMX Gee Bee R-2 a standout replica of the legendary golden-age racer that looks as good as it flies.
Constructed from advanced EPS material, the airframe is lighter and stiffer than standard EPO. This provides exceptional surface detail and flight rigidity for better aerobatic performance. The design is easily repairable using foam-safe adhesives, and a full range of replacement parts is readily available, ensuring your aircraft remains in peak condition after many flying sessions.
The UMX Gee Bee arrives 100% factory-assembled, removing any build time from your schedule. Equipped with industry-leading Spektrum 2.4GHz technology, it binds seamlessly to your 5+ channel transmitter. This allows you to transition from the box to the runway almost instantly, making it an ideal choice for enthusiasts who want to spend more time in the air.
