Who did the Cub Crafter?

O just flew the Cub Crafter around the rock in Gibraltar. It seems the flight dynamics are on a much lower level than the C152/C172/DA62. Pitching up or down does not behave anywhere near realism, nor does stalling the plane. The plane will just keep the set pitch or bank as if it was fly-by-wire. The stall will just sail down gently to the ground. But why is there such a difference?
