Hello Flanker1985, first of all thank you very much for your interest in my campaigns. I understand you want only historical flyables in the pilot career "For the honor of France" right?
Don't worry I won't turn your request down.
Actually I even believe it is already possible with just one small modification of only one file (not explained in the manual).
If my memory is correct, proceed as follows: first of all make sure you have a modded game version, and that you use the "ultimate edition" of my campaigns (D/L available at M4T). Find the folder JSGMEMODS/-FrenchWingsNoMods/DGen. In that folder, find the file PlanesFrC.dat and edit it to add the Curtiss H-75 and the Morane406: under each of the subcampaign headings DDG, BOF1, AirStart40, BOF2, add 2 lines: MS406 and P_36A3; under each of the subcampaign headings MedfR1 and TorchfR, add the line P_36A3; under the subcampaign heading MedfR add the line MS406. Be careful and add exactly these lines. Save and close your edited PlanesFrC.dat file. Do not try the Hurricane MkI: it is not flyable for allied nations in DGen. Then in JSGME, activate the options for the unmodded version "FrenchWingsNoMods" and "Battle of France & Vichy briefings". Finally, start your game and choose your pilot career and only historical flyable planes in the drop-down box menus available for each sub-campaign, before generating any mission. You should have the Curtiss H-75 and Morane 406 as available options. Later in the career you may switch back to the regular briefings, it will work.
Please let me know the results.
Note: the editing trick above should also work just with the unmodded version of my campaigns, version 10, also available at M4T, but the game itself must be modded to allow the Curtiss H-75 and the Morane 406 to be flyable.
