The E-flite Ultra-Micro UMX Vapor Lite HP RTF Electric Airplane lets you satisfy your urge to fly indoors almost instantly. This updated version of the classic Vapor slow flyer is smaller and lighter than the previous models. Its unique design approach and high performance combines slow flight capability with incredible maneuverability so you can enjoy flying in spaces even tighter than the average living room. The lightweight yet durable carbon-fiber airframe and feather-light film covering work in harmony to make gravity seem virtually non-existent. Combined with a powerful motor, you can fly at a wide range of speeds, plus harrier, hover and even perform aerobatics including loops, stall turns and more.

Even if you’ve never flown before, the UMX Vapor Lite HP airplane is light and stable enough to fly slowly, yet it’s also tough enough to handle most crashes and bumps against walls and furniture so getting the hang of it is easy. Best of all you can be flying in almost no time after opening the box. There’s no building involved—the Vapor Lite HP comes out of the box fully assembled and ready to fly.

HP Means High-Performance
Although the Vapor Lite HP is smaller and lighter than the classic Vapor models, we equipped it with the largest motor and propeller possible for short takeoffs, great acceleration and the power to hold and pull out of a hover.

Light, Durable and Assembled Airframe
The UMX Vapor Lite HP airplane features a proven airframe design that’s incredibly lightweight but is also extremely durable. Plus it arrives fully factory-assembled and ready to fly right out of the box—no assembly required.

E-flite Ultra-Micro UMX Vapor Lite HP BNF Basic Electric Airplane (345mm)
I received this from my wife as a Christmas gift. Out of the box the frame of the rubber was broken. Contacted HT on 12/26. At that date no parts were available but they did offer to send an complete new unit once they were available. As of the date of this review (12/31) bnf units have not come back in stock. Being the impatient guy I am, I ordered a new rudder and some spare props for Horizon and had the plane in the air 2 days later.

With only mini heli and drone experience I was able to get the plane flying around the mono posts in my basement relatively easily. It flys stable and level with a 70 mAh battery pushed all the way forward against the landing gear.

There have been some issues. I broke 1 of the land gear struts when I accidentally flipped open the box on top of the model. The problem was it broke off nearly flush with the mount. I tried to remove the other side to balance it out and it broke off as well. The round struts fit into a tight bore and are glued. The mount itself is glued to the frame. My solution was to glue the struts to the outside of the mount with loctite 495 and reenforce with a little clear tape. The repair is holding up very well and did not affect flight or ground take offs.

2nd issue is the rubber servo. It will not return to center from left. Right will return fine. It also has noticably more throw left then right. There seems to be no way to solve it. Every way you go about it is a compromise. I found it best to leave it be and actually FLY the plane. Not a huge deal but it does take away from the beginning friendliness of the plane.

Despite the set backs I still find the plane to be alot of fun.
