The E-flite UMX Ultrix BNF Basic Electric Airplane with AS3X & SAFE Select is novel, redesigned "Ultra Micro eXtreme" delta wing with aerobatic and 3D capabilities that delivers a flight experience as unique as its appearance.

This twin brushless motor-powered, delta wing airplane excels at smooth sport flying, basic aerobatics and even aggressive 3D — all in the same flight. It features an incredible power-to-weight ratio with hovering capability and unlimited vertical performance. Differential thrust adds yaw control and the ability to perform advanced aerobatic maneuvers including harriers, amazing flat spins and many more. The durable EPP construction makes this one of the toughest ultra micro models available. The included Optional-use SAFE® (Sensor Assisted Flight Envelope) Select technology makes the Ultrix easy enough for low-time pilots to enjoy, while still being exciting and involved enough for experienced fliers.

Features:
  • Innovative and unique design capable of smooth sport, aerobatic AND 3D flying
  • Powerful twin brushless motors deliver the power to hover and climb out vertically
  • Differential thrust for yaw control to perform flat spins and other maneuvers
  • Ultra micro size can be flown in more places and smaller spaces
  • Extremely durable yet lightweight, fully-molded EPP airframe
  • Industry-leading Spektrum™ 2.4GHz DSMX® technology
  • Easy to fly with optional-use SAFE® Select flight envelope protection
  • Unmatched stability and locked-in feel of AS3X® technology for smoother flight performance
  • Optional LED light kit/set (sold separately; EFLU6455) for flying at night
  • Fully factory-assembled and ready to fly

E-flite UMX Ultrix BNF Basic Electric Airplane w/AS3X & SAFE Select (342mm)
4.5 Stars since it’s almost perfect. I’ll start with the bad. The binding experience with an NX7e was miserable. It just would not bind no matter what I did. It wasn’t until I read on Reddit that many people were only able to bind when using the “hybrid” frame rate. I did that and binding happened instantly. I’m telling the Tx I’m using digital servos which is not the case. For a BNF that’s been around for years this should have been fixed.

Now for the good. It flies amazing on 1s, really stable and is very quick. For such a small aircraft it’s quite impressive how it flies. The EPP foam seems quite sturdy and dense, I would expect minor crashes to not be an issue. At most you’re breaking a prop which can be replaced.

Speaking of props, nowhere on the product page does it say a spare set of props are included in the box. I’m glad they were included but it would have been nice to know they’d be in there since I ordered spares separately.

Overall quite satisfied other than the binding issue.

My grandsons and I fly this crazy, fun airplane. We wore one out it is so much fun. Always have a spare. We fly more maneuvers with this airplane than any of my other airplanes. I.E. a Timber. Grandsons fly it to it's max. Just plain fun. Buy it.

Great fun. You can fly super fast if you have the room or if you feel like it you can fly it slow speed.

E-flite UMX Ultrix BNF Basic Electric Airplane w/AS3X & SAFE Select (342mm)
Amazing, best plane in my hanger. I have 7 or 8 umx planes this one is my favorite by far. Super slow or super fast. Safe mode or 3d crazy. Cool flat spins with the differential thrust. Super durable. Small and easy to bring, 1s batteries are cheap and easy to charge. Perfect 2nd plane to learn more aerobatics, i'de get the sport cub s for total beginner . The ultrix binds and flies great with the MLP6DSM rtf horizon controller. Was kind of a pain to bind to my radiomaster T-16 but i got it working.

E-flite UMX Ultrix BNF Basic Electric Airplane w/AS3X & SAFE Select (342mm)
Fun little airplane (with emphasis on "little"). Flies well slow and mild but can also get VERY aerobatic. I just have to keep it in close so I can see it. I'm running a 1S 800mah battery and pushing it about 3/4 of an inch up into the gap at the front of the battery compartment. That seems to provide perfect balance and also keeps the battery in place with no velcro or strap needed.
