Yeah, just think of it this way: when you build an aircraft with tricycle landing gear, a nose wheel, make it your reflex, your instinct, that you will check to see if you need to add weight up front. Whether the instructions mention it or not, because many sets of instructions won't.
As far as this model goes, you might consider putting it on a small base, like a section of concrete runway, etc. Then you can drill a little hole in one of the nose wheels and glue the aircraft down. Even if the base is simply stained, you could use this technique.
