What a great plane,I am not a great pilot by any means but this plane is so easy to fly. The plane looks great with its scale details and is capable of aerobatics and it just looks great flying around.

E-flite Ultra-Micro UMX Waco BNF Basic Electric Airplane (550mm)

Vivid blue on a pure white body is the best even if it is decorated, faithful scaling with little fun deformation is like a static model
However, although I think that it is the result of seeking lightness, because the color of the aircraft color is not the painting but the color of the ground of the foam material, the body of the fabric state is easily dented by just touching the nails etc.
Handling is not done carefully, it seems to be full of scratches.
When I looked at it as an RC airplane, it was too real landing gear
Because it is made up of two carbon rods as a core, there is no suppleness.
Since it is the place where the most load is applied in actual takeoff and landing, I am worried about whether it will be damaged when it is hard landing.


The feeling that I felt "fun" the first time I finished skipping, changed my mind to "jealousy" instead of "thanking the E-flite engineer", and while writing it.
However, it's just awesome.
There is no peculiarity, the maneuvering does not change from low speed to maximum speed.
Normally, it is necessary to adjust the maneuver according to the speed range, but there is no need to change it at all.
It reacts exactly by the amount of steering.
Far away from the wing tip stall, it does not even stall in the first place.
As long as we are raising the nose and do not apply a brake, we glide at a constant speed and keep coming down straight while maintaining the stable condition in all axes.
This is the first time for a scale aircraft.
If it is a profile aircraft, this kind of maneuvering sensation is standard but I feel even jealous of the engineers of E-flite who finish up to this point.
Since I am a field other than a field engineer, I understand how difficult it is, so I will respect their attitude and obsession to reach this area.
Although the talk went wrong, this peculiar airplane is a RC airplane which can be highly recommended to everyone from beginners to veterans!

Awesome little plane! This is the first UMX plane I have had and it was a dream to fly. All I did was bind it to my DX9, set up the servo throws as recommended in the manual and it was off! Literally the easiest thing ever. It fly's so nice, slow or fast, acrobatic or not. And it looks so nice as it cruises by you. I get about 5-6 minutes per charge on the E-Flite 280mh batteries. It lands so docile, cut the power and it will float in. Highly recommended.

This is an awesome little plane! Very acrobatic and easy to fly! If you get into trouble shut the power down and go pick it up. Holds up well to bad landings
