... Thanks Altavillan, But this didn't tell me a lot that I can understand. It didn't say what different size engines to make a plane of this size and weight become a 3-D plane. Or if this weight can be a 3-D.Like I said I am completely new to electrics. I bought a super cub electric to learn to fly on.I really like this plane but know nothing about it. Anyway thanks for the info... Jim
