The UMX Ultrix is a ton of fun and feels way more capable than its tiny size suggests, with smooth handling and enough power for some fun aerobatics. I can fly it in smaller fields and even larger backyards, and the AS3X and SAFE modes make it stable enough that I'm not constantly fighting the wind. Build quality is great for a micro, it goes together with a battery in seconds, and it's become my go-to plane when I just want to grab something quick and get in the air.

For starters, I own just about every awesome little E-flite UMX plane that is made. For some reason I hesitated for a long time on this one. I really expected it to fly poorly. Boy was I wrong! Flies like a dream in all phases of flight. Nice gentle slow "high alpha", smooth and steady high speed, crazy aerobatics, gentle to land. And with the optional light set EFLU6455 it is easy to fly at night. What a total hoot to fly!

This is one of the best mini planes in my fleet and it is by far the most enjoyable airplane from e-flite. It can be docile or it can be wild. Different settings from beginners to expert. Crash resistant and fully assembled, only the two rear fins have to be push in, that is all. I bind it to my DX-9 radio because I go the BNF version, and instructions are easy to set up. I use a 500 mah 1S battery and I get 8 to 10 minutes flight from them. Flat spins are amazing and as soon as you let go the sticks, level flights every time. No rudder on this plane, but twin motors do the same as rudder. Elevons for keeping it simple and fun. Flight is when is calm or flight it when is 20 mph, it will surprise you.

I love this thing. Cheap, super durable and capable. Only gripe is that it should of come with the light kit from the factory. cutting apart a new plane to add lights seems silly and the lights are awesome.... so you need them.

I really love this aircraft it turns a mediocre beginner pilot may be better than the other people I fly with but a terrible pilot just beginning on this journey makes me look like on all out pro doing tricks roles spins loops even this little flat spinny thing that it does with full rudder I haven't said that I have crashed it at full throttle going straight plowing nose down into the ground of course it did break the nose off (doing tricks as a novice and didn't get the safe back on)but it was a clean break I was able to get the foam glue and glue it right back on and didn't need some beat after that It has plenty of power it'll get you out of sticky situations because of having enough to do so I did change out the props but the regular props work fine they're just quite expensive compared to the alternative The only reason. The batteries you can use an 800Mah like I did there are other alternatives basically a one cell battery it has a high enough c-rate will work I did have some in my box from RC cars that only ones that didn't work cuz they didn't have enough high enough C rate discharge and it started cutting out the motor as if the battery was low so I haven't said that a higher enough output battery should work as long as it's a single cell with the correct plug you will be fine This thing flies awesome was easy to set up All I did was put the preloaded model from my menu in and bind and go it was ready to fly in less than 10 minutes. Little rudder style winglets are there and they just stick in to give you the lowest profile inside the box for easy carry which I love however mine do fit a little bit loose I didn't put much stock into that and just immediately started flying it I haven't lost one in flight yet and I have done some crazy stuff when I did plow nose first into the ground though it did pop both of them off as well as the battery door other than that never had them come off at all so I don't be too concerned if yours fit very loosely cuz of course mine hadn't flown off but if you wanted to you could just put a piece of you know the the fuzzy side of velcro on there and that would give you a little tighter fit if you're worried about it off it seems too too loose. I originally had the larger version the blue one and I sold it to a buddy just to get him in cuz the planes he were trying to fly were kind of older and not as easy so I let him fly this and then ultimately sold it to him I ended up getting the red one to try which is smaller to see what the difference was mostly it allows me to fly in a much smaller space I can fly right outside of my house The larger one flies pretty much exactly the same but of course the turns are a little bit wider and such , The bigger one flies on a small three cell pack so of course it does seem like it has a little bit more punch but I don't think there's any lacking of power on this plane on one cell at all it is definitely phenomenal I have seen some info about it having bushings instead of bearings on the motor so that might be a long-term effect that wouldn't be as great whereas the larger one has bearings it will probably last longer but I'll keep flying it and figure that part out.

Very very fun. For the money, it is an incredible plane. It can fly extremely slow or extremely fast, it can handle some wind, it is very durable. The light kit is awesome too, dont forget to make one of the switches on your transmitter change the colors of the LEDs, there is a very bright setting that is much better than the others. The one thing that is a bummer is that putting the props on you have to be careful... I suggest watching a youtube video. Get this plane!

I have never flown a wing aircraft. I took a chance on the jmx ultra. I am amazed at the control, acrobatics, and speed. This has turned into my favorite plane to fly in just a week. It is not a beginner plane. If you can fly simple acrobatics with a regular plane then this may be for you.
