Well that looks like fun, wonder if it will have the same characteristics as it's big brother... Easy to scale down the plane but air doesn't scale down

Flying more, crashing less. Feels great!

Yes that will be interesting to see. Our club has a monthly lmr contest and Radians are dominant. It would be hilarious if the UM version could out perform them!

Oh yeah. Interesting that the Radian is a ParkZone product, and the UM version is from E-flite.

How many of you guys have this so far?

I know I like mine even though I don't think it needs the AS3X:

I took it on some fun flights in the warm air last night and it just hung there in the sky even better than in these videos! I rarely get to fly during the day when thermals are most likely, but I was impressed with it last night.

A buddy was listening to a Flite Test podcast, and I guess in it they say you can use the computer connector on the umx Radian rx to turn off the AS3X. I'm gonna look into it.

I need to look into that too! I could get way more flight time with it without it and I honestly don't think it really needs it anyway. I prefer my planes that don't have it most of the time to those that do.

This video below centers around me nearly losing my new Ultra Micro Radian RC plane last night on a bright and sunny evening. While it was missing from my sight for what seemed like forever, in that helpless span of time I decided I needed to ensure this wasn't going to happen again with my next plane since this one was likely gone forever.

Thankfully, I was able to regain sight with it after spinning circles for a bit. What you will find in this video are a few ideas I applied literally to the surfaces of this RC Plane.

This is the highest I have taken my UMX Radian on video (I am guessing at least 500 plus feet) and I decided to keep the video shown below pretty raw. It includes some pretty funny parts that show the interaction between my camera woman and myself....but mostly her lol:

Heck! I expected it might fly a bit like a brick but this is the real deal! Definitely a great flying plane. Any results on the visibility improvements?

Default UMX radian

Hi Gang, new to the R/C world and this blog site. Have a bunch of time flying professionally, but just got past the small R/C choppers and the Night Vapor. Now feel ready to move up into something such as the Radian.

As I see it there are three models? Radian, Radian Pro and Radian UMX? Anyone have indoor experience with the UMX? We have an indoor site here in the DFW area of North Texas and I was interested in seeing if someone on here has flown it indoors and I guess the main question for me is would you buy the UMX again? BNF version?

Thanks
Dick

Sorry I didn't see this comment until now. The answer is yes, but I think I may need to go with a thin layer of reflective tape if I am going to be able to really fly up high since the improvements didn't make quite the impact I expected.

This should be just as easy to handle as the Night Vapor. The only different is if you are using the toy controller to fly it, you will need to upgrade to something with more range. This thing glides really well and thermals suck it up pretty quickly. As such, it could be out of range before you know it with the toy controller

Thanks GB, I guess I'm going about this in the right way. Started out with the small choppers and picked up a simulator and have been practicing on that, then the Night Vapor. Along with that was the DX 6i. That should work. So yeah, guess the Radian, UMX is next on the list.

Thanks for the response.

Default Picked up a Radian UMX and question

Hi Gang, Finally was able to get time and get over to the shop and pick up a Radian UMX. Great flying plane. First foamey for me.

Question..... Naturally the first time out I ran into a tree. Now I get about 1/4 inch flex forward and back at the wing tip. The nylon receptacle where the two screws mate from the fuselage to the wing are tight. I put some glue on the nylon receptacle and waiting for it to dry. Just trying to remember, will the wing tip flexing forward and back horizontally effect the flying capability?

I'm thinking that it might induce a little adverse yaw?

Anybody have any ideas?

I just use tape on either side along with the screws to keep the wing from moving. So far the results have been great and even after crashing it onto my neighbor's roof!

Here is the first video I recorded after that crash:
