add to cart

The E-flite® UMX™ Slow Ultra Stick is an ultra-micro “slow flyer” that was inspired by classic “Stick” models of the past and has been scaled down from the Slow Ultra Stick 1.2m so it can be flown in even more places and smaller spaces – indoors or out!

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!

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!
