How do I set -or- edit Aircraft classes for the menu

Question

X-Plane 11 separates the aircraft into classes ie. Airliner / Helicopter / General Aviation etc... Some of the aircraft that I have imported from X-Plane 10 are in "Other" and some ar in the wrong class. I thought of editing with Plane Maker but can not... I get an error about the Gps etc.

Answer 1

These fields must be set in the author window of Plane Maker. If you get an error when trying to edit the plane, it means it uses a very old version of the GPS or FMS and will need to have that removed or updated.
