I bought an Aircore 40 several years ago to fly out in the oil field when I'm out on job sites. It does well flying off of rough oil field roads and old well locations. It's nice not having to worry about repairs if you flip it on a rock on take off or landing. Mine flies pretty well with a Tower Hobbies .46 and it handles the West Texas wind pretty well too. It's one of my favorite planes I have, all the rest of which are balsa that I've built myself and I plan on teaching my step son to fly with it when he's ready. I'm thinking about buying a Colt to try out. I wish they still produced the little bipe.
