With HSFX you need to make a MODS folder.

Inside the mods folder you need.

MODS
*STD
*DIFF_FM_Mod
*YOUR NEW PLANE.
To make the STD [all cpas here] open the root game folder and you will see a file called " FILES" it will be near the top. Open it and inside you will see
com-gui-!18n
COPY AND PASTE THESE THREE FILES IN TO THE " STD" FOLDER YOU MADE.
com-----gui-----!18n
Inside the gui folder is a folder called game.
inside that is where the BUTTON FILE GOES.
