I just got my U can Do and it is a bit flimsy . I really don't care what it looks like I just want to learn 3D. There are negative comments on the forums and I can see why. The aileron was warped and the wrinkles in the monocote could not be straightened out no matter what I tried. It is a breeze to put together and I will be flying it soon with a Saito 100 . It looks like I will have to be careful with the speed and treat it carefully because it looks like it could break easily. I hear it flies really great though. I would like to get another plane which is built better and would like some suggestions . I will be using a Saito 100 if it fits. Thanks
