NOW EVEN EASIER TO FLY
The UMX Radian ultra-micro motor glider became a class favorite by delivering a unique flying experience you simply can't get from any other model. Due to its traditional motor glider design, the Radian is inherently stable and easy to fly almost anywhere — indoors in gymnasiums and other suitable spaces, and outdoors in most yards, parks and sports fields. The exclusive Spektrum AS3X technology of its installed electronics smooths out the effects of wind and turbulence to deliver a locked-in feel that makes it seem like you're flying a much larger airplane. E-flite engineers upgraded this new version to include optional-use SAFE Select technology, making the Radian even easier for more people to fly in more places. Plus, you can receive real-time battery voltage telemetry with compatible transmitters! It's the perfect next step after learning to fly, a great first glider and an exciting everyday sport model for a wide variety of pilots.

UPDATED FOR ULTRA-SMOOTH SOARING
The ever-popular UMX Radian has been updated and upgraded so it's even easier and more fun to fly than before! The ultra-micro motor glider now includes exclusive Spektrum optional-use SAFE Select technology and provides real-time battery voltage telemetry to compatible transmitters. This Bind-N-Fly Basic model arrives factory-assembled and nearly flight-ready right out of the box. Simply install the one-piece wing with a few screws, install a charged battery, bind it to your compatible Spektrum transmitter and fly. Advanced EPS construction provides a lightweight yet durable airframe. The distinctive, gracefully curved polyhedral wing and efficient airfoil deliver outstanding soaring performance and long flight times with or without motor power. The factory-installed power system features a coreless motor, gearbox and an efficient folding propeller. It produces excellent climb performance and extends flight times up to 10-20+ minutes with a mix of power on/off flying using 1S 150-200mAh batteries. Because of its ultra-micro size, the UMX Radian can be flown indoors in gymnasiums and other suitable spaces, or outdoors pretty much anywhere — in most yards, parks, sports fields and beyond! If you learned to fly with a HobbyZone Sport Cub S, you can use the same transmitter, battery and charger and make the Radian an economical next step. It's an ideal first glider or everyday sport model for low-time to experienced pilots interested in an easy to fly, ultra-micro class motor glider that delivers a unique flying experience!

Exclusive Technologies
This UMX Radian is equipped with exclusive Spektrum AS3X (Artificial Stabilization – 3-aXis) and SAFE (Sensor Assisted Flight Envelope) Select technologies. AS3X works behind the scenes to smooth out the effects of wind and turbulence to deliver 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 along with automatic self-leveling that can be turned on and off at the flip of a switch, making it easy to fly for low-time and experienced pilots alike.
Telemetry Capable
The UMX Radian is equipped with a control unit/flight controller that includes two servos plus an ESC and Spektrum receiver that provides real-time flight battery voltage telemetry to compatible Spektrum AirWare equipped transmitters (including the DX6e and 8e, DX6 G2/G3 and 8 G2, the DX9, NX6, 8 and 10, the iX12, iX20 and others) while you fly.

If you have a transmitter, all you need besides this are a few cheap little batteries and a charger to fly it. It's very easy to fly (use SAFE mode if you're new to flying) and glides very well. It's more engaging, IMO, than the larger Night Radian that I found boring. And it's easy to grab and go have a little fun with for a while. Also light enough that you don't need to register it with the FAA, etc.It's a very simple little plane, a joy to fly and can be flown like a normal plane (but is limited to loops, no rolls because no ailerons), used to slope soar or even catch thermals -- The latter very impressive for a plane this small. It has a tiny little brushed motor but that's all it needs and climbs like a champ.Simple is good.These are made my E-Flite, a brand under the Horizon Hobby umbrella, but buy it here instead. I bought a different, more expensive model direct from Horizon Hobby when it first came out, with a faulty aileron servo after one flight, and they sent me a new servo and expected me to figure out how to install it (and provide my own servo glue) on a brand new plane instead of simply sending a new wing that I could install in a couple minutes. When I asked for the latter, they didn't even bother to reply.Rude.With Amazon, you just send it back for a replacement and don't have to deal with any of that foolishness. That said, this is such a simple plane that you're unlikely to run into any defects.

Love the quality of the glider. I have flown it no more than 10 minutes because I don't have telemetry on the voltage of the battery and it is difficult to test the left over power, but it flys very well. Only 3 channels available (motor speed, elevator and rudder). Sometimes simple is better.

Lots of fun! Flew for the first time today in the backyard and is really easy to control. This would be good for someone starting out with the RC airplane flying hobby since it is so light weight. If you flew it into the side of a house I doubt there would be any damage. Worst that could happen is it gets stuck in a tree. Reminds me of a paper airplane. I have it paired with a Spektrum NX8 transmitter and these batteries:https://www.amazon.com/dp/B09GKDZ5YX

Fun little plane to fly, but skittish in the wind. (given its size, that's not surprising) It climbs very quickly and can drop just as fast, so a new flyer would probably not enjoy it nearly as much as someone who as more time on the sticks. The SAFE works great, so it is relatively stable, but just not with a breeze. I'm looking forward to many enjoyable flights with it and the need for such a small battery provides a LONG flight time if you don't run the motor the entire time. (Get to height, and glide down). Overall, it's a great buy and would recommend it! (For FrSky users, you will need a module to bind to it.)

It's a GLIDER. Understand what you're buying. It's meant to be small, light, and slippery. If it was built tough there would be more to it. Want something to fly that might handle some abuse? Get a Champ or Sport Cub.That aside, it's a fun thing to loiter around for 15-20min at a time chasing updrafts.

I'd been wanting an RC glider for years, but never got to the point of justifying the expense (to myself). This model for less than a C-note, plus a Specktrum DXS transmitter, batteries, a charger, a strap for the transmitter...all in for less than two-fifty. (My wife gave me an Amazon gift card that covered over half of it!) I was in business.Everything went together nicely out of the box...except the 1S batteries were light on velcro and I couldn't get the transmitter to bind to the plane. A trip to a craft store solved the velcro problem. A Youtube video solved the binding problem. (1. power to plane, 2. transmitter on with bind button pressed, 3. power to plane off, 4. transmitter off, 5. transmitter on, 6. plane on...voila!). Always turn on the transmitter before applying power to the plane!First flight: I went to a park down the street, tossed some grass in the air (very light breeze), and launched the plane into the wind. I was able to fly the plane to altitude, turn off power to the prop and let it glide down to a landing within a few feet of myself. I even caught a few small thermals. On grass, it made a gentle landing. I did that a few more times until the battery was depleted (according to the gauge on the transmitter). I was very happy!Second flight: My wife went with me to the park to take pictures. I had a similar experience to the first flight...but a couple of launches in I ended up flying into a tree! That required a trip back home to get a 12' pole with a pool net attached to push it out of the tree.A couple of launches later, my wife suggested I fly the plane away from a small group of spectators with a dog that was frantically barking at my plane. In the process of doing that, I got the plane up above the tree line (having learned that tree's are bad), and a stronger wind caught it. The plane began drifting away from the park, I couldn't bring it down (I think I was making it go higher instead of lower). I lost sight of the plane for a second (behind those darned tree's!) and it was gone. :(That was when I told my wife that "I meant to put my name and phone number on it." That was when she realized (again) that she had married an idiot.But...I liked the who experience so much that I'm buying a replacement Radian UMX. A few months down the road I'm already looking at the Conscendo model!
