Review: Complete Awesomeness - 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. Review: Its un-beliveable - 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. ## Features - Ultra micro radio control airplane with durable, lightweight construction - suited for flying almost anywhere, with speed, plenty of power to hover, and unlimited vertical performance - Twin, brushless motor power and delta wing design provide a unique flight experience with a performance range that includes smooth sport flying, basic aerobatics and aggressive 3D flight - Differential thrust adds yaw control and ability for more experienced pilots to perform advanced aerobatic maneuvers including harriers, amazing flat spins and more - Stability and precision of AS3X 3-axis technology with optional SAFE Select for stabilization and self-leveling in Beginner, Intermediate and Advanced Modes - REQUIRES (sold separately): Full-range 5+ channel Spektrum DSMX/DSM2 Transmitter, 1S 3. 7V 500mAh LiPo with JST Connector, and Compatible LiPo Charger ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B083HHMTJW | | Additional Features | Portable | | Age Range Description | Kid | | Are Batteries Required | Yes | | Batteries are Included | No | | Battery Description | Lithium-Ion Polymer | | Best Sellers Rank | #231,460 in Toys & Games ( See Top 100 in Toys & Games ) #290 in Hobby RC Airplanes | | Brand Name | E-flite | | Color | White/Red/Black | | Customer Reviews | 4.3 4.3 out of 5 stars (149) | | Included Components | E-flite UMX Ultrix RC Airplane, Installed Brushless Motors (2), Installed Linear Servos (2), Installed Spektrum 6-Channel Receiver (1) with Brushless ESCs (2), Product Manual | | Is Assembly Required | Yes | | Item Dimensions | 15.6 x 15.3 x 2.6 inches | | Item Type Name | RC Airplane | | Item Weight | 544 Grams | | Manufacturer | Horizon Hobby | | Manufacturer Maximum Age (MONTHS) | 1188.0 | | Manufacturer Minimum Age (MONTHS) | 14 | | Manufacturer Part Number | EFLU6450 | | Material Type | Plastic | | Model Name | UMX Ultrix | | Model Number | EFLU6450 | | Number of Batteries | 1 Nonstandard Battery batteries required. | | Number of Items | 1 | | Operation Mode | Remote Control | | Power Source | Electric | | Scale | 1:18 Scale | | Size | 342mm | | Theme | RC Hobby | | Toy Vehicle Form | Airplane | | UPC | 605482496770 | | Unit Count | 1.25 Count | ## Images ![E-flite UMX Ultrix BNF Basic EFLU6450 Airplanes B&F Electric - Image 1](https://m.media-amazon.com/images/I/71t6EPgjmSL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Complete Awesomeness *by C***I on May 1, 2023* 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.

Flight is when is calm or flight it when is 20 mph, it will surprise you. ### ⭐⭐⭐⭐⭐ This plane is not for beginners, Pilots must have an intermediate level of experience *by J***T on April 20, 2021* Its a fun little plane, nit for beginners though ,you definitely need to have the concept down of operating an RC Plane.Its very fast, and moments are very quick. You can slow it down to where it hovers or you can speed it up to where you can lose it in 20 seconds. It handles the wind like a champ!!! Make sure you keep up.high because it flat so its very easy to get away from you... It also can change directions on a dime as well as hover or float precisely into your hands.... Does crazy spins, knife edges, inverted flights and loops...Amazing plane ## Frequently Bought Together - E-flite UMX Ultrix BNF Basic EFLU6450 Airplanes B&F Electric - E-flite LED Set Ultrix EFLU6455 Replacement Airplane Parts - E-flite 60mm x 2.5mm Prop Set CW CCW 4 EFLP60205 Replacement Airplane Parts --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/183309853-e-flite-umx-ultrix-bnf-basic-eflu6450-airplanes-b-f](https://www.desertcart.be/products/183309853-e-flite-umx-ultrix-bnf-basic-eflu6450-airplanes-b-f) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-06*
