Thank you for purchasing the E-fl ite® UMX™ ASK-21 scale RC sailplane. A fi rst of its kind in its size class is a fully functional 4-channel aircraft capable of loops and rolls, as well as traditional thermal and slope
soaring. Lightweight and sleek, your new UMX ASK-21 is equipped with AS3X® System technology specially tuned for the many variations of fl ight conditions you’ll encounter, so that you get the smooth experience similar to that of fl ying a giant-scale sailplane. And like the giant-scale sailplanes, this UMX ASK-21 is
tow hook equipped making it aerotow capable when paired with the powerful E-fl ite UMX Carbon Cub SS (EFLU1180). Another strong benefi t of the AS3X® is its outstanding ability to stabilize the glider while on a tow line or Hi-start and help prevent common issues, such as heading loss, which can make smooth fl ight diffi cult. Please be sure to read through this manual carefully so that you can successfully enjoy all the benefi ts this outstanding ultra-micro model has to offer.

AS3X Stabilization Delivers
Breakthrough Performance
Horizon Hobby has always made RC sport, scale and unique aircraft with the kind of performance experts appreciate. Now the exclusive Artificial Stability – 3 aXis (AS3X) system helps take performance expectations in ultra micro aircraft a quantum leap higher.
Based on the successful use of MEMS sensor technology within the AS3X Stabilization System essential to Blade® ultra micro flybarless
helicopters, the specifically tuned AS3X System for airplanes helps invisibly correct for turbulence, torque and tip stalls when encountered.
Furthermore, the outstanding control agility delivers an ultra smooth, locked-in feel that obeys your every command with performance that’s natural feeling. It’s so gratifying, in fact, that it’s as though you’re the RC pilot of an expertly tuned, giant-scale model.
AS3X will change the way you’ll want to fly now and in the future. To see what we mean, go to www.E-fliteRC.com/AS3X.
Charging Warnings
The included battery charger (EFLC1000) has been designed to safely charge the Li-Po battery.
CAUTION: All instructions and warnings must be followed exactly. Mishandling of Li-Po batteries can result in a fi re, personal injury, and/or property damage.
•By handling, charging or using the included Li-Po battery, you assume all risks associated with lithium batteries.
•If at any time the battery begins to balloon or swell, discontinue use immediately. If charging or discharging, discontinue and disconnect. Continuing to use, charge or discharge a battery that is ballooning or swelling can result in fi re.
•Always store the battery at room temperature in a dry area for best results.
•Always transport or temporarily store the battery in a temperature range of 40–120º F (5-48º C). Do not store battery or aircraft in a car or direct sunlight. If stored in a hot car, the battery can be damaged or even catch fi re.
•Always charge batteries away from fl ammable materials.
•Always inspect the battery before charging and never charge dead or damaged batteries.
•Always disconnect the battery after charging, and let the charger cool between charges.
•Always constantly monitor the temperature of the battery pack while charging.
•ONLY USE A CHARGER SPECIFICALLY DESIGNED TO CHARGE LI-PO BATTERIES. Failure to charge the battery with a compatible charger may cause fi re resulting in personal injury and/or property damage
•Never discharge Li-Po cells to below 3V under load.
•Never cover warning labels with hook and loop strips.
•Never leave charging batteries unattended.
•Never charge batteries outside recommended levels.
•Never attempt to dismantle or alter the charger.
•Never allow minors to charge battery packs.
•Never charge batteries in extremely hot or cold places (recommended between 40–120° F or 5-48° C) or place in direct sunlight.

Charging the Battery
Your UMX ASK-21 comes with a 1S 3.7V Li-Po Battery Charger and a 1S Li-Po battery. You should only charge your 1S Li-Po battery with a Li-Po charger, such as the included charger or the E-fl ite® Celectra™ 4-port charger (EFLC1004).
Refer to the battery warnings. It is recommended to charge the battery pack while you are inspecting the aircraft. The fl ight battery will be required to confi rm proper aircraft operation in future steps.
Please visit www.horizonhobby.com for optional battery adapters.
The Battery Charging Process
1.Charge only batteries that are cool to the touch and are not damaged. Look at the battery to make sure it is not damaged e.g., swollen, bent, broken or punctured.
2.Remove the cover on the bottom of the charger and install four of the included AA batteries, noting proper polarity. Replace the cover after the AA batteries are installed.
3.Slide the battery into the slot on the charger. The end cap of the battery is specifi cally designed to allow the battery to fi t into the slot one way (usually with the label on the battery facing outward) to prevent reverse polarity connection. However, check for proper alignment and polarity before proceeding to the next step.
4.Gently press the battery and its connector into the charge jack/connector located at the bottom of the slot in the charger.
5.When you make the connection successfully, the LED on the charger turns solid red, indicating charging has begun.
6.Charging a fully discharged (not over-discharged) 150mAh battery takes approximately 30–40 minutes. As the battery nears full charge, the LED begins to blink.
7.When the battery is fully charged, the LED blinks approximately every 20 seconds or goes out entirely. If the LED stays on when the battery is removed, the AA batteries in the charger are low.
8.Always unplug the battery from the charger immediately upon completion of charging.
CAUTION: Overcharging a battery can cause a fi re.
CAUTION: Only use a charger specifi cally designed to charge a Li-Po battery. Failure to do so could result in fi re causing injury or property damage.
CAUTION: Never exceed the recommended charge rate.
CAUTION: Only use an E-fl ite 6V power supply (EFLC1005) with this charger. DO NOT use a 12V power supply or property damage and injury could occur.

Transmitter and Receiver Binding
Binding is the process of programming the receiver of the control unit to recognize the GUID (Globally Unique Identifi er) code of a single specifi c transmitter. You need to ‘bind’ your chosen Spektrum DSM2/DSMX technology equipped aircraft transmitter to the receiver for proper operation.
Any JR® or Spektrum DSM2/DSMX transmitter can bind to the AS3X DSM® receiver. For best fl ight performance of the UMX ASK-21, it is recommended that you use a transmitter with dual rates. Please visit www.bindnfl y.com for a complete list of compatible transmitters.
NOTICE: When using a Futaba® transmitter with a Spektrum DSM module, reversing the throttle channel is required.
Binding Procedure
1.Refer to your transmitter’s unique instructions for binding to a receiver.
2.Make sure the fl ight battery is disconnected from the aircraft.
3.Power off the transmitter.
4.Connect the fl ight battery in the aircraft. The receiver LED will begin to fl ash rapidly (typically after 5 seconds).
5.Make sure the transmitter controls are at neutral and the throttle and throttle trim are in the low position.
6.Put your transmitter into bind mode. Refer to your transmitter’s manual for binding button or
switch instructions.
7.After 5 to 10 seconds, the receiver status LED will become solid, indicating that the receiver is bound to the transmitter. If the LED does not turn solid, refer to the Troubleshooting Guide at the back of the manual.
For subsequent fl ights, power on the transmitter for 5 seconds before connecting the fl ight battery.
Installing the Flight Battery
1.Lift the front of the canopy and pull the canopy forward off the fuselage.
2.Install the flight battery onto the hook and loop strip (A) in the battery compartment as far forward as possible.
3.Refer to Initializing AS3X instructions for connecting the battery to the receiver.
4.Install the canopy on the fuselage
Do not operate the ASK-21 for longer than 25 minutes on fully charged battery.
NOTICE: Always ensure that the battery is secured in the aircraft using hook and loop tape.
CAUTION: Always disconnect the Li-Po battery from the aircraft receiver when not fl ying to avoid over-discharging the battery. Batteries discharged to a voltage lower than the lowest approved voltage may become damaged, resulting in loss of performance and potential fi re when batteries are charged.
