Introduction

Scaled down from the extremely popular Slow Ultra Stick 1.2m and inspired by the classic ParkZone Ember models, the E-flite UMX Slow Ultra Stick is an ultra-micro "slow flyer" that can be flown in even more places and smaller spaces! Use a range of 1S batteries for flying indoors in gymnasiums, garages, and other suitable spaces or to fly outside almost anywhere in calm to low wind conditions. The UMX Slow Ultra Stick is capable of slow and easy cruising and performing basic aerobatics including loops. You can even install the optional LED light set to fly in darker conditions and at night. Plus, you can choose between two factory-assembled versions: the convenient, all-in-one-box RTF (Ready-To-Fly) version that includes a Spektrum battery, charger, and an SLT6 transmitter equipped with a USB-C port for direct connection to a PC for easy plug-and-play use of the included trial version of the RealFlight Trainer Edition RC flight simulator. Or the BNF (Bind-N-Fly^®) Basic version that helps you lower costs by using your own compatible Spektrum DSMX/SLT-equipped transmitter, battery, and charger. Either way, you can be flying almost anywhere in just the time it takes to charge a battery!

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!

Skill Level 2 – Next Step After a Trainer, Some Experience Required

"Next Step" aircraft, like this one, are the best choice for those who have successfully learned to fly with a trainer and are ready to graduate to their next aircraft. It's also an easy and extremely fun to fly model for experienced pilots!

Are you new to flying RC (Radio Controlled) aircraft? Although the UMX Slow Ultra Stick is very easy to fly, we recommend learning to fly with one of our purpose-built trainer aircraft, such as the HobbyZone^® Apprentice STOL S 700mm. It's the most capable, durable, and easiest-to-fly ultra-micro trainer yet because it's equipped with exclusive and innovative SAFE technology that makes it possible for almost anyone to learn to fly successfully! The Ready-To-Fly (RTF) version includes everything needed to fly and is a perfect choice for a new RC pilot.

Ready-To-Fly Convenience

This Ready-To-Fly (RTF) version includes a 6-channel transmitter equipped with Spektrum SLT 2.4GHz technology and everything else you need to fly, including AA batteries for the transmitter, a rechargeable 1S 150mAh battery for the airplane, and a USB charger. That means there's nothing extra to buy so you can fly! The included transmitter can also be used with other ultra-micro/UMX (Ultra Micro eXtreme) aircraft equipped with dual-protocol receivers featuring Spektrum SLT FHSS technology. Plus, it can be used with the included trial version of the RealFlight Trainer Edition RC flight simulator and the "full" version of RealFlight Evolution!

RealFlight Included

RealFlight is the world's #1 RC flight simulator, and the Trainer Edition includes many of the most popular Horizon Hobby trainer aircraft from Blade, HobbyZone, and E-flite. It also features Virtual Flight Instructor lessons that help new pilots learn to fly successfully because they can practice flying on a desktop PC at home or on a laptop just about anywhere else! You can 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!

Exclusive Technologies

The UMX Slow Ultra Stick is equipped with exclusive Spektrum AS3X and SAFE Select technologies. AS3X is expertly tuned to work behind the scenes to smooth out the effects of wind and turbulence, delivering 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 and automatic self-leveling that can be turned on and off at the flip of a switch to make it easier to fly!

Uniquely Capable

The simple design was inspired by classic "Stick" models from the past and is scaled down from the more modern-day design of the Slow Ultra Stick 1.2m. This results in an ultra-micro-sized "slow flyer" that's easy and fun to fly in even more places and smaller spaces! From indoors in garages, conference rooms, and gymnasiums to outdoors in yards, parks, and almost anywhere else.

Durable Design

The unique "pop off" prop saver design plus the lightweight yet durable airframe is tough enough to handle everyday flying punishment without getting bent out of shape. And if you damage any airframe parts or components and can't repair them, a full line of replacement/spare parts is readily available.

Factory Assembled

The UMX Slow Ultra Stick arrives factory-assembled and nearly ready to fly right out of the box. Simply install the one-piece wing that quickly and easily snaps into place without fasteners or tools, and you're ready to fly!

Optional LED Lights
