Just letting you know that today I flew my UCANDO about 1/2 dozen times. On my last flight I noticed that my barrel rolls were not as fast as usual even with high rates. I continued to perform 3D with hovers and everything else. When I laned I noticed I had lost one of my ailerons. The servo arm was broke. Now I know I flew more then half of a 10 minute flight without one of my ailerons and I barely noticed the difference.

I am amazed how well it handled. So if you lose an aileron ... have no fear. You won't even notice hardly till its on the ground.
