The Giles will 3d if it is built light. It is definetly a 60 size ship and more like a .90 2 stroke or strong .90-120 4 stroke plane. I have one but built it stoke. If I were to do it again i would make a number of mods to lighten it and use a different engine. It does fly well but the extra is suppose to fly better. I have the .60 size ready to go in the spring.
