Things that make ya say humm... I live and fly in china, I have been been flying what seems to be one of the the prototypes of the now called UcanDo planes for about 2 years now. I am not sure if it had name then, I have just called it "BUTTUGLY".
It is one of the most entertaining planes I have every flown. I seldom get tired of flying it. The only things it can't do is be pretty and go fast.

I first saw it a model avation expo in Beijing about 2 years ago, It looked like it would be a good flyer, and I wanted one bad, but the booth attendent said it was not in production yet. Then a month later, a friend of mine, showed up at the fld with perhaps one of the first ones. I was so impressed with it I pulled out my cell phone and ordered 2 of em on the spot.

By reading the posts here, I have noticed some differences in the production model and my mine. the main thing is the weight, mine weighs in at a little over 5 lbs with a YS63, 4-cell battery. I know that may seem unbelieaveable for a plane this big, but the construction of mine is so light weight, that I really have to be careful with it during transport, and I am sure that any crash at all, would just vaporize it. It is also uses a very light weight transparent covering material with no graphics (a little hard to see far away, but I always fly it close). Mine also has a single servo / pull-pull through a double ended bell crank set-up for the elevator.

Mine has very noticable roll and pitch coupling, but it can be coaxed into the most increideable slow inveted flat spin you have ever seen.

I often hand lauch it for take-offs... straight up. It is so cool.

I really enjoy flying this plane, but not in windy conditions it is just too lite.

I can't believe you guys are putting 90's on this thing, I seldom use full throtle on my 63. But maybe they decided to make the production version a little more robust, mine (at 5 lbs) is pretty flimsy.
