No. A .15 will not hover this plane. A .28 would come closer, but this is not really the type or designed for 3D type of flight. They say you can fly a brick if you have enough motor, so I guess anything is possible. You never know unless you try. I didn't have to add any weight to it to balance it. Sorry but I have no means of posting pictures, but if you look at Lanier's pictures in their adds, that is what mine looks like, it is the first plane I copied someone elses covering ideas.
sorry I can't be of more help.
