The Weaver Aircraft Company of Ohio (WACO) was founded by aviators whose love of flight and daring tenacity led them to produce over 60 different aircraft models in just 28 years. This made WACO one of the leading manufacturers of aircraft during the Golden Age of Aviation. In 1985 the founders of the Classic Aircraft Foundation set out to reincarnate the iconic YMF model. And now, the E-flite® UMX™ WACO has been updated and upgraded to be an even easier and more fun to fly tribute to the revered biplane! It’s equipped with optional-use SAFE® Select, is both 2S and 3S compatible, plus provides real-time battery voltage telemetry to compatible transmitters. And because of its ultra-micro size, the UMX WACO can be flown indoors in gymnasiums and other suitable spaces, or outdoors in many yards, parks, and sports fields! It’s an affordable, convenient, and easy to fly replica of the modern-day classic that’s also available in two trim scheme color options.


  • An officially licensed scale replica of the modern-day yet classic YMF-5 biplane design
  • The most affordable, convenient, capable, and easiest-to-fly WACO model yet
  • More powerful 2S and 3S-compatible outrunner motor and ESC
  • Compatible with the Spektrum™ DXS transmitter included with many RTF models
  • Real-time battery voltage telemetry with compatible Spektrum transmitters
  • Spektrum receiver with industry-leading 2.4GHz DSMX® technology
  • The unmatched stability and locked-in feel of exclusive AS3X® technology

  • Completely factory-assembled and ready to fly right out of the box
  • Factory-finished with a scale trim scheme available in two color options

E-flite UMX WACO is now equipped with optional-use SAFE Select that makes it more stable than ever before, plus exclusive Spektrum™ AS3X® that keeps things smooth so it feels like you’re flying a much larger model, even in windy conditions. The factory-installed brushless power system features an upgraded 2S- and 3S-compatible outrunner motor. Install 2S 280mAh batteries for performance similar to the original model, or use 3S 300mAh batteries for more speed and unlimited vertical performance. The control unit includes an ESC and Spektrum™ receiver that provides real-time flight battery voltage telemetry to compatible Spektrum AirWare™ equipped transmitters while you fly. It’s constructed of advanced EPS material for a lightweight yet durable airframe, and it’s now available in two trim scheme color combinations including fully-painted yellow and lighter-weight unpainted white base versions. Best of all this Bind-N-Fly® Basic model arrives 100% factory-assembled and is ready to bind to your 5+ channel DSMX®/DSM2® equipped transmitter so you can be flying within minutes of opening the box! The lightly loaded biplane design and ultra-micro size are perfect for flying indoors in gymnasiums and similar large spaces, or outdoors pretty much anywhere — from yards to parks, sports fields, and beyond.
