EN Thank you for purchasing the E-flite® UMX™ ASK-21 scale RC sailplane. A first 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 flight conditions you’ll encounter, so that you get the smooth experience similar to that of flying a giant-scale sailplane.
EN Preflight Checklist 1. Charge flight battery. 6. Set dual rates. 2. Install flight battery in aircraft (once it has been fully charged). 7. Adjust center of gravity. 3. Bind aircraft to transmitter. 8. Perform a radio system Range Check. 4. Make sure linkages move freely. 9. Find a safe and open area. 5. Perform Control Direction Test with transmitter. 10. Plan flight for flying field conditions.
EN 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-flite® 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 flight battery will be required to confirm proper aircraft operation in future steps. Please visit www.horizonhobby.
EN Wing Installation 1. Lift the front of the canopy (A) and pull it forward off the fuselage. 2. Align the 4 holes in the wing (B) with the 4 screw posts in the fuselage. 3. Secure the wing to the fuselage by fully tightening the 4 included screws (C). 4. Connect the aileron leads to the aileron ports (D) on the receiver. There is no difference between the two connections on the receiver. Left and right servo connectors do not have to be connected to a particular port. 5.
EN Transmitter and Receiver Binding Binding is the process of programming the receiver of the control unit to recognize the GUID (Globally Unique Identifier) code of a single specific 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 flight performance of the UMX ASK-21, it is recommended that you use a transmitter with dual rates.
EN Initializing AS3X Initializing AS3X also occurs after binding as previously described, but subsequent connection of a flight battery requires the steps below. 1 Power on the Transmitter, then wait 5 seconds 2 3 Install the flight battery and connect it to the receiver. Keep the plane immobile and away from wind for 5 seconds. Continuous LED The AS3X system will not activate until the throttle stick or trim is increased for the first time.
EN Control Direction Test You should bind your aircraft and transmitter before doing these tests. Move the controls on the transmitter to make sure aircraft control surfaces move correctly and in the proper direction. Make sure tail linkages move freely and that paint or decals are not adhered to them. To obtain the best flight performance, we recommend using a DSM2/DSMX radio capable of Dual Rates. The suggested settings shown here are the recommended starting settings.
EN Hi-Start Hook Installation 1. Put the Hi-Start hook (A) in the slot in the bottom of the fuselage. 2. Install the screw (B) over the hook to hold it in place. Disassemble in reverse order. A B Installed Hi-Start Launch Choosing a Launch Area Your local AMA sanctioned flying field is the best location for flying. However, if you do not have access to such a field, many other open areas will work.
EN Hi-Start Launch (continued) Do not attempt to fly or operate your ASK-21 any longer than 25 minutes on a battery. 1. Choose an anchor spot in firm soil and drive the stake at an approximate 45 degree angle to your chosen launch path (See image A). 2. Slide the rubber loop through the open section on the loop end of the stake. Pull on the assembly to ensure it is securely attached to the stake, and the stake is secure in the ground. 3.
EN Towing Towing with the Carbon Cub is only recommended for advanced pilots. While towing, be sure to fly in a large, open space. Also be sure that you have two pilots, one for the sailplane, and one for the towplane. Recommended Aircraft Alignment for Takeoff Wind The E-flite® UMX ASK-21 sailplane is designed to be towed by the E-flite Carbon Cub (EFLU1180) from a smooth runway. A tow line (approximately 28 feet (8.5 m) long) is included with the UMX ASK-21 or is available separately (EFLU1257).
EN Recommended Aircraft Towing Positions When Flying 28 ft (8.5 m) Tips for Towing • Continually communicate with the pilot of the towplane and make sure they are aware when you are having difficulty, or are releasing the tow line. • Ensure that you keep the sailplane’s wings level at all times. You should not try to turn the aircraft, but rather allow the tow plane to drag the aircraft around turns. • Avoid slack in the line while flying.
Flying Tips and Repairs Flying We recommend flying your E-flite® UMX ASK-21 outside in no greater than moderate winds. Always avoid flying near houses, trees, wires and buildings. You should also be careful to avoid flying in areas where there are many people, such as busy parks, schoolyards or soccer fields. Consult local laws and ordinances before choosing a location to fly your aircraft. For additional tips on flying your ASK-21, please refer to the product page at horizonhobby.com.
EN Additional Safety Precautions and Warnings As the user of this product, you are solely responsible for operating in a manner that does not endanger yourself and others or result in damage to the product or the property of others. This model is controlled by a radio signal subject to interference from many sources outside your control.
EN Troubleshooting Guide (Continued) Possible Cause Solution LED on receiver flashes and aircraft will not bind to transmitter (during binding) Problem Transmitter too near aircraft during binding process Power off transmitter, move transmitter a larger distance from aircraft, disconnect and reconnect flight battery to aircraft and follow binding instructions Bind switch or button not held long enough during bind process Power off transmitter and repeat bind process.
