This is a really good looking model, with exquisite detail both inside the cockpit and the outside of the plane. The flight model feels very authentic as well. Why only 4 stars then? Well, there is something wrong with the sound. The engine sound or pitch only increases up to the throttle halway mark and then it stays the same. You can see the rpm and temperatures etc changing, but the engine sound stays flat for the entire top half of the throttle movement. This is very unconvincing and really spoils my enjoyment of this beautiful plane.
