28.7" Wingspan E-flite UMX Radian Glider with AS3X Flight Stabilization - Bind-N-Fly (BNF) - EFLU2980

The E-flite UMX™ Radian is a powered sailplane that packs all the simple fun of the larger ParkZone Radian into a much smaller package that’s an absolute delight to fly. AS3X technology gives a pilot the feeling of flying a much larger glider especially outdoors because of its renowned ability to smooth out the effects of wind and turbulence. Its distinctively curved wing delivers outstanding lift and impressive glide ratio using 3-channel control simplicity. The lightweight brushed power system requires just a single-cell Li-Po battery to provide excellent launch performance and long flight times. Plus the one-piece wing can be easily removed and stored in the handle-equipped box making your ability to soar through the clouds as convenient as can be. You’ll be in the air in no time thanks to great features like:

Folding Propeller
For maximum glide efficiency, the ESC is specially programmed to work with the folding propeller so it opens quickly and folds back to streamline the airframe.

Removable Wing
With the removal of just two screws the fuselage and wing can be separated for easy transport and storage within the custom packaging provided.

Long Flight Times
The included E-flite 150mAh 3.7V 1S 25C Li-Po battery can be charged with the provided charger from any convenient USB power source. Average flight times of 10 minutes or more can be easily achieved on a single charge.

AS3X System Equipped
The specifically tuned AS3X System in the UMX Radian ultra micro motor glider is designed to work behind the scenes to provide instantaneous attitude corrections when turbulence, torque and tip stalls haphazardly interrupt the way you want to fly. Moreover, the aircraft flies incredibly smooth while providing you with control that feels natural and utterly accurate. The result is the feeling of flying a much larger, well tuned sailplane that’s convenient enough to fly just about anywhere.

Great fun - excellent price

Bought this because it was on sale, but it would have been a great buy at full price! Bound right up to my DX8 and now I have something that is easy to carry to the field. Flies great - as long as the wind is below 3 or 4 mph - above that, don't let it get downwind!

UMX Radian

My second one. Very easy to fly even for a beginner. Fly for a long time even without thermal because this little thing want to stay up there. As3X make it fly like a much larger plane. Only have one con: The wing should have been fix with a better system than the 2 screws, but has this is a small plane, it's not a big issue. Pierre from Quebec, Canada

UMX Radian Purchase

No problem with the product and price but customer service not good. Order not shipped for several days and took long time to be delivered. By contrast, I ordered an E-Flite RES Mystique direct from Horizon Hobby. It was shipped almost immediately and arrived less than a week later in Australia at very low cost, by DHL Express

Super fun, easy to fly plane

Got this as my second plane and have been very happy with it. Small size so it's easy to take in the car and fly pretty much anywhere. Even as a beginner, most landings have been done by catching the plane. Almost no trim needed using the DX8 gen2. Took it to some small sand dunes and had a blast slope soaring in light wind. Crazy stable even at slow speeds, fast climbs, and even good at doing loops. This is by far my most used plane and I plan on buying another if it ever wears out. Motion RC did a great job packaging and shipped out fast, really good customer support. Only thing I would like to see improved on is if the wing could be easily removed and put back on for travel. I just leave mine fully assembled for now and built a box for it (the tiny screws used to hold the wing on would be too annoying to deal with ******** them on and off for each flight). Maybe magnets, or a snap in system could be used on a future version?:) Also would be cool if the AS3X could be turned on and off with a switch for expiernced pilots.

Great little plane!!

Bought this plane to have as we travel around in our travel trailer. What a blast this thing is! Easy to put together. Binding was easy with my DX6. Very little trimming necessary and it flies like a dream. Easily handled 5 -6 mph winds but 7 and above got a but rough for it. Got 6+ minute flights routinely. It loves thermals and just doesn't want to quit flying when you bring it in to land. Catching it mid-air made for spectacular finishes to the many flights. Wow!! What a cool plane
