E-Flite UMX Radian BNF with AS3X Technology Unboxing, Maiden Flight, and Review

This is the unboxing, maiden flight, and review of the new E-Flite UMX Radian BNF with AS3X Technology RC plane with AS3X Technology. It is also not the the BNF Basic package, so it comes with a USB charger and battery in addition to the Radian UMX RC Glider.

Here are my Unboxing, Maiden and Review Notes:

Cons:
- Fragile
- Not easily transportable like previous UMX planes
- Brushed motor

Pros
- Handles stiff and swirling winds pretty well
- Good slow speed handling
- Performs loops well
- Good flight times
- Powered unlike the UMX ASK-21
- Fun

This is how Horizon Hobby describes this RC Sailplane otherwise known as the Ultra Micro Radian BNF, not to be confused with the Parkzone Radian:

"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."

All I can say is that the UM Radian or Baby Radian is something I am pretty impressed with so far.

I really like how you included post-flight with honest comments about how your nitpicks were no longer a concern.  That gives confidence to a new buyer!

Update.. GBLynden your efforts do not go unappreciated.  Your review steered me to purchase this plane and you were correct, it is a gem!!!   I have piloted this plane through 5 - 160mah batteries so far. Most flights lasting approx. 10 - 15 minutes.
The last flight was my longest, lasting 23.5 minutes. 
5 minutes of motor run time = 23.5 minutes of smiling...  Crazy.
Thanks again for your videos and review of this plane.

You got me I had to order one!
Hopefully my E-Flite LP6DSM radio will bind to it? It's a Spektrum 6 channel DSM radio that was used for a Blade Heli.

Nice review. Like the USB charger, nice little bonus... the 2 screw thing must be common on gliders as that's what came on my park flyer. Had a problem with 1stripping out did the old rubber band trick and it works fine. Nice footage!

[JohnVHRC]

neat little bird. Horizon should pay you for all the exposure!

[rcpete]

I guess you got this a while before the night radian? The comments about the lightness and cheap has put me off this a bit I was steering towards this instead of the night radian because of its smaller size..

[bradsgold]

What happens when the battery gets low?

[bltefft]

The CG is 31mm from the leading edge of the wing - the manufacturer said with the battery centered, that should be the CG.

Good video. Thanks, . I just got this plane, unboxed it and about ready to fly

[mikester]

I 'm glad you made those last comments positive, otherwise flammable comments would ensue, with great I believe people refer to those sorts of comments as Flaming ETC or something like that?

[eeshaangauthamrao]

Can this be a great first Rc airplane?

[tobiasscharnberg]

Hi, you said you maidened it in quite a bit of wind and wouldn't recommend higher winds. I don't see trees moving though. How much wind can the little radian take? I already own an UMX Skywalker without ASX and it's only fly able without any wind at all. If the radian is like that I wouldn't be able to fly it very much because here is always some wind except for maybe half an hour on an evening.
Thanks for the review and the flying vids!

[bltefft]

I don't use the screws. I copied a mod of another and use magnets to hold the wing in place.

[adamrobinson]

Would they survive bad crashes or how tough are they?

[InternetFun]

Will the space walker RTF transmitter bind to this plane?

[MichaelSmith-fksl]

Whats your thoughts on this being a beginner plane. I am also looking at the Sport Cub S. Ler me know. And thank you for your reviews. They are always

[mikeflytime]

Nice review!   Will probably be adding this one to the hanger.
Any idea on the wind speed during the maiden?
Also, will the Hobbyzone Champ batteries work in this plane?

[rodpolice]

Just got mine today and it arrived with the rudder hinge broken (the foam part, so the only thing holding the rudder to the vertical stabilizer is tape). Gonna have to call horizon! I really want to fly it but I may have to return it to get a replacement so.... :( nice video, though!

[alexboatingfishing]

The unit does not come with the remote??

[Innuendoh]

I'm new to the hobby and wanted your opinion. Would you suggest the UMX Radian here, or the Micro Calypso by Flyzone, or the Hobbyzone Coscendo S w/ SAFE technology as my first plane to learn?
