First of all there are two warbirds in the sim. Flyingiron’s Spitfire and Milviz’s Corsair. In the video you can see that if you don’t make a very soft landing and at the right speed with the spitfire, it tends to bounce several times until the wing loses lift. In the sim, no matter how hard the landing has been, there are no bounce. It’s like the wheels stick to the ground. The same happend with other taildragger airplanes.
