acerc has it right, they are not much different to fly, but are a hoot to fly. I own a tower hobbies fun51 that has only 10 flights on it so far, has an OS .46 LA engine on it, 44 inch span, big thick airfoil. If I can fly it, anyone can. At $59.00 it's a great deal for a kit now days. Easy to build also and quick.
