E-flite UMX Gee Bee R-2 RC Airplane Introduction

During the “Golden Age of Aviation,” Gee Bee aircraft were among the pioneering pylon racing designs that captivated just about everyone. Their teardrop-shaped fuselages, coupled with small wings and control surfaces, required a skillful hand to fly well, but with the right pilot, they dominated the race course. Back by popular demand, the E-flite® UMX™ (Ultra Micro eXtreme) Gee Bee R-2 returns with a more powerful 2S and 3S compatible power system, a modified airframe to handle the extra power and speed, plus exclusive AS3X® and optional-use SAFE® Select technologies that make it easier and more enjoyable for a wider range of pilots to fly.

E-flite UMX Gee Bee R-2 RC Airplane Overview

The E-flite® UMX™ Gee Bee R-2 is ready to soar through the skies in more places and smaller spaces thanks to its handling that has more in common with a friendly sport model than a short-coupled golden age racer. Awe-inspiring with an authentic scale outline and abundant details such as flying wires plus a pilot, this replica offers handling so remarkably smooth, you’ll want to fly it every day. AS3X® technology works behind the scenes to help you enjoy the outstanding stability and control you always wanted but never thought possible in such a small airplane, let alone in a model of the Gee Bee. Optional-use SAFE® Select flight envelope protection technology delivers automatic self-leveling plus pitch and bank angle limits that make it possible to successfully fly such a unique design even if you’re an intermediate RC pilot. It also features a quieter and more powerful 2S and 3S compatible motor, along with a modified fuselage and stronger wing, designed to handle the extra weight, power, and speed when using 3S 280–300mAh batteries. Best of all, it arrives 100% factory-assembled and ready to bind to your favorite Spektrum™ DSM2/DSMX®-equipped transmitter so you can be flying in almost no time! And it all adds up to deliver a model of the classic Gee Bee that’s a dream to fly while offering an exciting and incredibly unique flight experience from large yards and small parks to sports fields and beyond!

Skill Level 2 for the >E-flite UMX Gee Bee R-2 RC Airplane
Skill Level 2 – Some Experience Required

Skill Level 2 aircraft, like this one, are suitable for RC pilots who already have some experience and the skills to assemble and/or set up and fly similar class models. Although this is the easiest-to-fly Gee Bee model yet, it’s not a suitable first RC aircraft for new pilots or a “next step after a trainer” model for low-time RC pilots. You should have the experience and skills necessary to successfully fly higher-performance ultra-micro models like the various UMX Timber models, or larger models like the E-flite T-28 Trojan 1.1m, the Commander mPd 1.4m, Timber 1.5m models, or other similar class models before attempting to fly the UMX Gee Bee R-2.

Are you new to flying RC (Radio Controlled) aircraft? If you are, we recommend learning to fly with one of our purpose-built trainer aircraft, such as the HobbyZone Apprentice STOL S 700mm (www.horizonhobby.cc/appstolrtf). It’s equipped with exclusive and innovative SAFE technology, making it possible for almost anyone to learn to fly successfully. The Ready-To-Fly (RTF) version includes everything needed to fly and is a perfect choice if you’re a new RC pilot.

Exclusive Technologies for the >E-flite UMX Gee Bee R-2 RC Airplane
Exclusive Technologies

This UMX Gee Bee R-2 510mm features exclusive Spektrum AS3X and SAFE Select technologies. AS3X works behind the scenes to smooth out the effects of wind and turbulence, delivering a locked-in feel that makes it seem like you’re flying a much larger airplane. Optional-use SAFE Select offers pitch and bank angle limits, along with automatic self-leveling, that can be turned on and off at the flip of a switch, making this the easiest to fly flat foamy model yet!

Bind-N-Fly Completion Level Advantage for the >E-flite UMX Gee Bee R-2 RC Airplane
Bind-N-Fly Completion Level Advantage

Already own a Spektrum™ transmitter? Bind-N-Fly (BNF) aircraft make getting into the air quickly and with the best control experience possible easier than ever. They come out of the box with the power system, servos, and a Spektrum 2.4GHz receiver installed, so all you need to do is bind the receiver to a compatible transmitter, finish any final assembly, and fly!

Higher Performance for the >E-flite UMX Gee Bee R-2 RC Airplane
Higher Performance

The factory-installed brushless power system features a much quieter 2S and 3S-compatible outrunner motor. This power system setup delivers similar performance to the original when flown with 2S 280–300mAh batteries (a suitable JST-RCY to JST-PH adapter, such as the SPMXCA327, may be required). Alternatively, it’s significantly faster and delivers unlimited vertical performance when flown with 3S 300mAh batteries.

Telemetry Capable for the >E-flite UMX Gee Bee R-2 RC Airplane
Telemetry Capable

The UMX Gee Bee is equipped with a control unit/flight controller that includes an ESC and Spektrum receiver that provides real-time flight battery voltage telemetry to compatible Spektrum AirWare-equipped transmitters (including the DX6e and 8e, DX6 G2/G3 and 8 G2, the DX9, NX6 to 20, the iX12 to 20, and others) while you fly.

Scale Detail for the E-flite Gee Bee R-2 1.0m RC Airplane
Scale Detail

Beyond the true-to-scale outline, flying wires attached to the wing and landing gear, a clear canopy, a pilot figure, and more are scale details that enhance the looks and flying experience of this unique model.

Durable Design for the >E-flite UMX Gee Bee R-2 RC Airplane
Durable Design

Construction with advanced EPS material delivers a lightweight yet durable airframe with more surface detail, which is lighter and stiffer than EPO or EPP. It’s also easily repairable with odorless/foam-safe CA, Foam 2 Foam, epoxy, and other foam-friendly adhesives. Or, if you damage any airframe parts or components and can’t repair them, a complete line of replacement/spare parts is readily available.

Fully Assembled for the >E-flite UMX Gee Bee R-2 RC Airplane
Fully Assembled

The UMX Gee Bee arrives 100% factory-assembled and ready to fly right out of the box! It’s equipped with industry-leading Spektrum 2.4GHz technology that binds to your 5+ channel DSMX/DSM2-equipped transmitter, allowing you to fly within minutes of opening the box.

Bind-N-Fly Completion Level Advantage

Already own a Spektrum™ transmitter? Bind-N-Fly (BNF) aircraft make getting into the air quickly and with the best control experience possible easier than ever. They come out of the box with the power system, servos and a Spektrum 2.4GHz receiver installed so all you need to do is bind the receiver to a compatible transmitter, finish any final assembly and fly!

This Bind-N-Fly Basic model is equipped with a Spektrum 2.4GHz DSMX® receiver featuring AS3X® (Artificial Stabilization–3-aXis) technology that works behind the scenes to smooth out the effects of wind and turbulence so you enjoy a sense of stability and precision that makes it feel like you're flying a much larger, expertly tuned aircraft.

If this is your first model of its type, or you want an extra margin of safety while familiarizing yourself with the airplane, you can enable the optional-use SAFE® Select flight envelope protection technology built into the receiver. No programming is required.


With SAFE Select enabled, you get:

Pitch and Bank Angle Limits

  • These envelope limits keep the airplane from rolling or pitching upside down. They also prevent excessive climb or dive angles.

Automatic Self-Leveling

  • The airplane instantly returns to and holds level flight when the sticks are released and in the center position. It's also helpful for keeping the wings level during takeoffs/launches and landings.

Easy Switch Assignment—No Complex Programming Required

  • The simple procedure for assigning a transmitter switch to turn SAFE Select features on and off doesn't require any complex programming and takes just a few seconds. For UMX models like this one, SAFE Select is automatically assigned to channel 5 (Gear) so you can turn it on and off with any switch assigned to that channel (switch A by default on most Spektrum computer transmitters).
