Just Flight have two caps for that project : publisher and developer. Their new Piper Aircraft completes the aircraft selection for GA simmers looking for advanced simulations.
Their new PA-38 Tomahawk for FSX P3D is highly detailed with neat visuals, detailed and accurate 3D models.. but there are also a good number of custom coded systems. Failures may happen too !
Its X-Plane 11 version is also available.
