If you want to change the prop, click the Propulsion button in the menu and then pick the name of the propeller in the "Select Propeller" list. The names of all the props in the sim are listed in the drop down menu.

The other items mentioned above were not for general consumption here. It's for people who have the sim, and I'm interested in getting feedback from the people w/ experience w/ these particular planes. When they click on items in the list a text box appears that explains what the parameter does in plain English (in aerodynamic terms).

[Edit - Ok, so you have the sim. You should see the text box when you edit the parameter above in the Aerodynamics section. Propeller normal force is the side force that a propeller produces in yaw, i.e. knife edge flight or sideslip.]
