Ya Spacewalker is ia very nice looking gentle flying model that you can get either a kit or an ARF ..You can run them on Electric Glow or Gas.... Goldberg Tiger about 60 size with a few mods during the build , like add flaps if you wish , maybe retracs , Or the Ultra Sport With a few mods during the build , like add flaps etc etc. I guess it depends on if you want to build a kit or buy an ARF and assemble...We need to know more to really help you.. What is your flying skill level ?..Not everybody knows how to build or has to space to dedicate to the building part of the hobby so ARF's are their only option and thats fine but when you are looking for a plane there is no use looking at the kits...Unless you have a buddy that will build it for you...
