GTN 750 integration

A small change that would improve the GTN integration, is to set Airplane=4 in the F1GTN.ini file.

The provided setting produces a single engine plane on the GTN screen, the suggested change will produce a twin.

+1, Bert. When installing updates to the Redux, I often forget to do this until I see the single-engine plane in the GTN display--minor hassle.

Thanks. I've updated the master build folder file to set Airplane=4 for the 750's and 650's.

Thank you, Bill.
