Flight Replicas has made their SuperCubv5 available to download completely free of charge. This is an update of the original FSX SuperCub Extreme2 and has been brought in line with the Prepar3D v5 standards.
New features include newly-developed wings, tires and also upgraded cockpit parts. Furthermore, there is now a new external model with functional instruments. This means you could start the aircraft before getting into the cockpit and then jump into the usual virtual cockpit view to then fly as normal. The update also adds detailed 4K textures and improved aerodynamics. You can even hand prop the aircraft for starting the plane up.
