The Weaver Aircraft Company (WACO) was a leading manufacturer during aviation's Golden Age, and the E-flite UMX WACO is an updated tribute to its revered biplane legacy. This ultra-micro version is easier and more fun to fly than ever, packed with modern technology. It comes equipped with optional-use SAFE Select for increased stability and a factory-installed power system compatible with both 2S and 3S LiPo batteries. The control unit includes a Spektrum receiver that provides real-time flight battery voltage telemetry to compatible transmitters. Thanks to its convenient size, the UMX WACO is versatile enough to be flown indoors in gymnasiums, or outdoors in parks, yards, and sports fields, offering a classic biplane experience anywhere.
This upgraded UMX WACO delivers an impressively smooth flight experience, thanks to exclusive Spektrum AS3X technology that counters the effects of wind, making it feel like a much larger aircraft. The power system offers choices: use a 2S battery for relaxed flights or a 3S battery for more speed and vertical performance. The airframe is constructed from advanced EPS material, providing a lightweight yet durable structure. As a Bind-N-Fly Basic model, it arrives 100% factory-assembled and ready to bind to your 5+ channel DSMX/DSM2 transmitter, getting you in the air within minutes. This makes it an affordable and convenient replica of a modern-day classic.
Already own a Spektrum™ transmitter? The Bind-N-Fly (BNF) UMX Waco makes getting airborne swift and simple. It arrives with the power system, servos, and a Spektrum 2.4GHz receiver already installed – just bind to your compatible transmitter, complete any final assembly, and you're ready to fly!
This UMX Waco is equipped with exclusive Spektrum™ AS3X® and SAFE® Select technologies. AS3X works subtly to smooth out wind and turbulence, providing a 'locked-in' feel like a larger plane. Optional SAFE Select offers pitch and bank angle limits with automatic self-levelling, making this the easiest-to-fly Waco yet!
The UMX Waco features a control unit with an ESC and Spektrum receiver that provides real-time flight battery voltage telemetry. This data is sent directly to compatible Spektrum AirWare™ equipped transmitters (including DX6e, NX series, iX series, and others) while you're flying, keeping you informed.
The factory-installed brushless power system features a 2S and 3S-compatible out-runner motor. This upgraded setup delivers similar performance to the original with 2S 280–300mAh batteries, or unlocks more speed and unlimited vertical performance when you use 3S 300mAh batteries.
The factory-finished airframe boasts a variety of scale details, including simulated flying wires and a pilot figure with a scarf.
Constructed from advanced EPS material, the UMX Waco delivers a lightweight yet incredibly durable airframe. Should you ever encounter damage to any parts, a full range of replacement and spare components are readily available to keep your model in top condition.
The UMX Waco arrives 100% factory-assembled, ready to fly straight from the box! It features industry-leading Spektrum™ 2.4GHz technology that binds seamlessly to your 5+ channel DSMX®/DSM2® equipped transmitter, getting you into the air within minutes of unboxing.
This model is best suited for RC pilots who already have some experience. While it's the easiest-to-fly Waco, it's not ideal as a very first RC aircraft or a 'next step' after a basic trainer. Pilots should be comfortable with higher-performance ultra-micro models or similar larger aircraft.
