I think he meant the flaps seperate into three pieces as they are lowered, right? Many Warbird models have a flap option. A scale Warbird benefits greatly from flap useage. However, I have a Great Planes F4U Corsair without flaps and doesn't need them as this is a Fun Scale airplane. It's an ideal First Warbird. Easy to take off, fly and land. I have more Scale Warbirds that I do use the flaps when landing. This is something good to practice on your simulator at home. Put in variable wind conditions and practice landing with flaps. Once you get the hang of it, you'll see how much more realistic your airplane looks when landing. Not only that, but crashing on the sim doesn't cost you anything. One more thing; don't forget the Warbird has a very useful control surface called a RUDDER. Please use it!
