UMX WACO BNF Basic with AS3X and SAFE Select, Yellow Introduction

The E-flite® UMX™ WACO blends classic style with state-of-the-art features including a 2S and 3S compatible power system and optional-use SAFE Select to give you one of the most rewarding Golden Age biplane flying experiences at any size!

UMX WACO BNF Basic with AS3X and SAFE Select, Yellow Overview

The E-flite UMX Slow Ultra Stick is simple and affordable. It’s also incredibly easy and fun to fly for low-time to experienced pilots looking for a no-hassles fly-almost-anywhere experience they can’t get with any other model! Based on the more modern-day design of the Slow Ultra Stick 1.2m and inspired by similar “slow flyer” models from the past, it can be flown in even more places and smaller spaces – indoors and out. Use a 1S 100–150mAh battery to fly indoors in garages, conference rooms, and gymnasiums. Or, use up to a 210mAh battery to fly outdoors almost anywhere in calm to low wind conditions. You can even fly in lower light conditions and at night after installing the optional LED light set (EFL-1113)!

The Ready-To-Fly (RTF) version includes everything needed to fly in one box and is a perfect choice if you're looking for maximum convenience and value. From the Spektrum SLT6 2.4GHz transmitter you can use with other Bind-N-Fly® (BNF) Basic aircraft compatible with SLT FHSS technology to the 1S 150mAh LiPo battery and a convenient USB charger that can be used with a variety of power sources, there's nothing extra you need to buy or provide! A BNF Basic version is also available for pilots who want to use their favorite Spektrum DSMX-equipped transmitter along with batteries and chargers they may already own. Both versions include exclusive AS3X® and optional-use SAFE® Select technologies, plus a reliable power system featuring a “pop off” prop saver design, a control unit including an ESC, servos, and a dual-protocol (DSMX and SLT FHSS) receiver that are factory-installed in the lightweight yet durable airframe that’s nearly ready to fly right out of the box. Simply install the wing by quickly and easily snapping it into place and you can be flying in almost no time!

Although we recommend learning to fly RC with one of our purpose-built trainer aircraft, such as the HobbyZone® Apprentice STOL S 700mm, the RTF version also includes a Steam® key to download and activate a trial version of the RealFlight® Trainer Edition RC flight simulator. The simulator features many of the most popular Horizon Hobby trainer airplanes, helicopters, and built-in Virtual Flight Instructor lessons. This helps new and low-time pilots learn to fly successfully by practicing on a desktop PC at home or on a laptop just about anywhere else! Simply use a USB-C cable to connect the included SLT6 transmitter to a compatible USB port on your computer to fly for up to 100 minutes. Then, you can purchase RealFlight Trainer Edition or Evolution to fly any time and for as long as you’d like!

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

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.

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.

Fully Factory-Assembled

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.

 


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.

Lightweight Design

IConstruction 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.

 

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.
