Ok flew the plane Thursday total weight is 11lbs.7oz. with the os 1.60 it has plenty of power, unlimited vertical plus. After reading all the posts I was afraid it would be a tough plane to land. Let me tell you it lands better than most of my planes. Yes it will never be a 3d plane but it a very clean flyer. I only got a couple flights on it not enough to trim it good and set up the radio but I can tell I'm going to like it.
