This plane is your Black Horse stick. It has full length ailerons that you can cut to make a crow set up. It is really light for sure ... the plane is very easy to build and there are not building issues at all. I got no idea what they mean about 4D but this is not a pure 3D plane. I flew mine with a SA72 and it was more than enough power. Back then I was not really into 3D yet so I cannot say how good it will be for 3D.
