It doesn't really matter to me how a plane gets built, especially for new pilots. Some guys really like to build and work with their hands, and others don't. Some are good at it and others aren't. A young pilot in my club has phenomenal talent with the sticks and is very careful with his planes. But he'll probably never build one. He can't even assemble an ARF; his dad does it for him. But he's having a blast with the hobby and becoming very proficient in his flying. What's important is not so much how the plane got built, but rather that it be a good airframe that is suitable for teaching a new pilot how to fly and equipped with adequate hardware, engine, and radio gear.
