You all may have come to a point where you want to use FSXPilot together with one of your third party aircraft. If you have started the simulation, loaded your third party monster plane and started FSXPilot you will receive an error message saying that plane 'xyz' is not known to FSXPilot and that you might consider adding the plane to your aircraft library. But how to do that ?

Adding aircraft in FSXPilot PRO

The process is described in detail in the PRO documenation. 

In short, please open the aircraft option dialog with the new plane and copy parameters from a matching aircraft by using the "Copy parameters ..." button. Tweak the parameters here until the plane flies really well. 

Adding aircraft in FSXPilot Shareware version 

The shareware version is now deprecated. Use the aircraft option dialog box to add new aircraft.
