E-flite Radian

E-flite Radian

This Radian is the larger sibling to the UMX radian with a 2 meter wingspan, there is even a larger version, the Radian XL that has a 2.6 meter wingspan. So this is the middle sized, although still quite large, Radian.

After flying the UMX Radian for awhile I decided I was ready for its big brother. I have heard from many places that the larger E-flite Radian flies just like the little one, well as an inexperienced pilot I have to disagree.

I think the big difference between the 2 is the AS3X system in the UMX which provides a lot of stability and helps keep the plane flying level and smooth.

With the larger plane and the lack of AS3X I find it much harder to control, to the point that I have put it nose-first into the dirt twice now. Yes, on my first maiden flight, about 2 minutes into the flight I lost control and put it into the ground at high speed. It broke the fuselage in half and crumpled the nose to the point it could not be repaired.

It is very nice that a replacement fuselage is available for less than $30. It took me about an hour and some E6000 to strip the parts I need from the old fuselage and get the new fuselage ready to fly. It was easy to do with some patience and care.

The second flight was even worse than the first. I did not keep it in the air much more than a minute when it felt like it was not responding to my commands. I think it was responding but I just had no idea what to do to get it to pull out of the dive it was in. So BANG, back in the dirt. At least this time I think I can glue it back together and not replace any parts, we’ll see.

My plan now is to find someone at the airfield who can buddy-box with me and give me some lessons in flying fixed wing planes. To tell you the truth I could use that kind of help with multi-rotors and ground RC.

Even though I have had my issues with the Radian, I would still recommend it to anyone looking for a starter powered sailplane, but not as a first plane.

After a couple of years flying multi-rotors I decided to give a fixed wing plane a try. At some point I built a Flite-Test Trainer which I never really got to fly due to my total lack of experience. Then I did some research and decided to buy an E-flite UMX Radian.

There are many versions of the Radian and the UMX is the smallest and cheapest of the bunch at around $90.00 for the Bind-and-Fly version, meaning you have to supply your own transmitter to fly it. There is a FPV version that comes with a camera and transmitter, along with much larger version all the way up to the Radian XL with a 2.6 meter wing span.

The UMX Radian has been a great plane for me to get started with, the AS3X system does an amazing job keeping it level and steady even in a moderate amount of wind. But I feel like the AS3X system is not allowing me to learn the skills I need to fly larger planes that do not include include it. More on that in a later post.

And most amazingly, this little plane is able to catch thermals and ride them until the plane is a dot in the sky. The first couple of times I caught a thermal and took it up and up it was a real thrill. Even with the 150mah batteries I regularly get 10 full minutes of flying and every now and then I get as much as 20 minutes.

The plane is so docile and easy to fly that I am usually sitting in a chair in the shade while flying it, but once it becomes a dot in the sky it is best to stand up and pay a bit more attention, but one of the really great things is that it is so light that even if you plant it into the ground you most like won’t break anything.

I highly recommend the UMX Radian to anyone looking for a small inexpensive docile flyer that can take a bit of wind and take some bad landings without breaking.
