Scale airplanes are much harder to land (in most cases) than aerobatic or sport aircraft, due to hi wing loadings. The stall speed is high so if you get a little slow they tend to drop on the runway causing a bounce. Most any pilot can fly a warbird, but landing is an art all it's own. It takes a good pilot to get one down every time with out bouncing or scraping a wingtip. Even the best will occationally bounce one.
