Product Information

Introduction

Producing over 60 different aircraft models in just 28 years, the Weaver Aircraft Company of Ohio (WACO) was one of the leading aircraft manufacturers during the Golden Age of aviation. The iconic WACO aircraft model has long been an iconic plane in the Golden Age flying scene and now the E-flite UMX WACO takes it to another level. Upgraded and updated you can now fly this tribute to the esteemed biplane in a fun and easier to fly scale detailed version. This WACO comes packed with features including real-time battery voltage telemetry to compatible transmitters along with 2S and 3S LiPo compatibility and optional use SAFE Select flight envelope protection. Due to its ultra-micro size you can fly the E-flite UMX WACO in big indoor spaces such as gyms or stadiums plus outdoors in your backyard or the local sporting fields. To top all of that this WACO is also affordable, can be flown straight out the box, and, is an easy to fly scale replica of the Golden Age classic that is also available in two different colour schemes.

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.

 

Bind-N-Fly Completion Level Advantage 
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!

 

Exclusive Technologies 
Exclusive Technologies

This UMX WACO is equipped with exclusive Spektrum™ AS3X® and 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!

 

Telemetry Capable

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.

 

Higher Performance

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.

 

Scale Finishes

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.

 

Lightweight Design

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 – Some Experience Required 
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. 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.

 

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).
