I've just finished putting one of these Hawks together. It's because I have serious misgivings about the c of g given in the booklet that I signed up to this site in order to find out if other people have a more informed opinion on this. All these reports of spiralling into the ground, it worries me somewhat. I wonder if the to my taste too far back c of g has anything to do with all that spiralling, as even I know that a rearward c of g makes a plane less stable. Now that I found this place I suppose I'll be reading the reports and reviews first next time I fancy a plane and think I really need that one too!
