I have purchased the Piper Saratoga and the Piper Seminole. Since the updates to prepar p3d and updated planes, I cannot set the VS on the autopilot of the Seminole. Also cannot set the altitude and Vs on the Saratoga. I hope they will work on a fix for this. Also the landing gear alarm for the Saratoga was never fixed. There’s nothing worse then buying something that doesn’t work proper. 🙁
