haha, I said Most of them crash. Which is true. Ive seen scale master vids, and alot of stupid mistakes done with some very great models..yank and bank! I will say this, there are those out there that can build amazing models and fly them very well, but there is not as many of them as there are the arf assemblers that fly well! There is nothing wrong with going either way, I enjoy building kits....just prefer to fly them.
