Thanks everyone for your answers, but sorry to say they did not work.

I spent 4 hours over at S A S reading every thing they have posted about
Adding MODS to HSFX.
Here is what I found for FOLKS like me that have not added anything to
Their HSFX game before.

1.Make a folder in your MAIN game called MODS or Mods they both seem to work.
2.Now make three folder inside the MODS folder
A.Plane folder you wish to use- in my case the HE51C-1.
B.Next folder named –all in CAPS -> STD
C.Next folder is named -> Diff_FM_mod
For folder A that’s the plane you downloaded. That goes here.
For Folder B. Go to your FLIES fold in the main game and COPY&PASTE these three files { com gui !18n }
Inside the com file is where you find the air.ini. file to paste what you need for your new plane.
For folder C go to the SAS site and download this file and place in the folder Diff_FM_mod.
Diff_FM_Mod

After I had done this it all worked – Thanks to a kind Person at SAS that helped and told me about the Diff_FM_mod that was the FIX.
This is the address for the HOW TO INSTALL mods in HSFX.
