Its implied by there being only one mod pack, isn't it? Unless of course the UP people want to keep their own FMs, in which case there will probably be a switcher in the JSGME to allow people to choose from the default AAA/SAS/HSFX FMs and the altered UP FMs. SAS will probably continue producing updated buttons files to account for new aircraft being added between releases of the new mod pack, but there will only 1 FM per aircraft, or at most two.

I'm not asking to have only one MODPACK.
I only wish we had a unique and genuine flight model.
for all MODPACKS.
and so with the SAS is to launch a new file BUTTONS each new aircraft.
I think the AAA should do the same.

Okay, but whether you are asking for one unified modpack or not, that is the way the mod communities are going to go for all future modpacks. HSFX4.1 and UP2.0 are the last individual modpacks, in the future there will be only one modpack that will contain the work of all the major mod communities. Until that point I myself am quite happy using the SAS buttons with UP2.0.
