Motocalc does not have Ultra Stick and Slow Stick?
I downloaded Motocalc to try again, but am surprised that the Slow Stick (GWS) and Ultra Stick airframes are not in the database.
Also, can't find GWS HD and slow fly props. Is there a way to get them?
Perhaps I need to read the manual again.

There are several Ultra Sticks in the user contributed database (I have no idea how accurate they are).
Any airframe that is not present can easily be created. Start with the manufacturer's data (wingspan/area/profile, weight etc.) and add the power system. Then adjust the airframe weight to get the correct all up weight. If you own the model then make your own measurements.
For the GWS Slowstick I entered:- wingspan 46.3in, wing area 505sqin, empty weight 8oz, wing thickness 1%, camber 5.5%, AOA 2%, rounded corners, average finish, fixed gear, some protusions.
I have a table of GWS prop constants on my website here.
