Description

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. Overview This updated and upgraded version of the 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. In The Box Needed to Complete Features This UMX WACO is equipped with exclusive Spektrum AS3Xand SAFE Select technologies. AS3X works behind the scenes to smooth out the effects of wind and turbulence to deliver 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 to make this the easiest-to-fly WACO yet! The UMX WACO is equipped with a control unit 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 G2/3 and 8 G2, the DX9, NX6 to 20, iX12 to 20 and others) while you fly. The factory-installed brushless power system features a 2S and 3S-compatible outrunner motor. This upgraded power system setup delivers similar performance to the original when flown with 2S 280–300mAh batteries (a suitable JST-RCY to JST-PH adapter may be required), or more speed and unlimited vertical performance when flown with 3S 300mAh batteries. The factory-finished airframe features a variety of scale details including simulated flying wires and a pilot figure with a scarf. Plus, it’s now available in two trim scheme color options including a fully-painted yellow and a lighter-weight unpainted white base version. Construction with advanced EPS material delivers a lightweight yet durable airframe. And in the unfortunate event you damage any airframe parts or components and can't repair them, a full line of replacement/spare parts is readily available. The UMX WACO 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 so you can be flying within minutes of opening the box. 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. And although this is the easiest-to-fly WACO model yet, it’s not a suitable first-ever RC aircraft for new pilots or “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 WACO.

  • Worth getting
Excellent plane high performance with a 3s battery
Reviewed in the United States on March 28, 2026 by David Keefe

  • Fantastic take the edge off plane! Just get one already if you haven't, you need this!
Just did 4 flights in as soon as it arrived and this plane has greasy take offs and landings. It's pretty light on its feet. On landing just keep a straight line and feather the elevator with like 20 - 25% throttle. As soon as you see the front wheels touch, dial back the throttle and don't turn until you have stopped fully because it does get swirly after landing and you don't want to scrape the paint off the wings. ... show more

  • Super fun, gorgeous little biplane.
4 stars only because it came in the wrong color. Otherwise, the plane is incredible. With a 3s 380mah battery it gets unlimited vertical and flies high-energy for about 10 mins per battery. Cruises super smooth and slow, and the AS3X with SAFE comes in handy a lot. Already had several rough landings that were easily fixed with a peice of tape, right back into the air. Very durable and fun, since there is much less risk involved if you are to crash it, since it is so lightweight. Super easy to do 3D maneuvers, flying flat spins, high-alpha, knife edge, waterfalls, inverted, and of course loops and barrel rolls galore. ... show more

  • Well Pleased
Had two flights so far. Went well and I am pleased wit it. Be very careful when removing the battery hatch cover not to break the small foam tabs. I broke one and glued it back with CA glue. It looks impressive in flight as well as on the ground. Take off with less than half throttle. Take off speed is about a walking pace. Not an aircraft for windy days! ... show more

  • Destroyed on first attempt
This product fell apart the first time we used it. It is made of styrofoam & we tried to piece it back together with duct tape. With every flight attempt we were back inside attempting to fix the broken part. Also the Amazon suggested controller was the wrong one. We ended up getting a Spektrum DXs that worked but I wouldn’t even waste your time with this plane. Find a different one. ... show more

  • Just buy it, you'll like it
Very quick aircraft. Flys great. Servos and esc are well matched with the waco. Great airplane to fly in light to medium wind. Lands awesome, comes in a little hot but easy to control. And it looks sharp. No assembly required. Fly right out of the box. Also it store in the box to keep protected while traveling to the airfield. ... show more
