Your best bet is to del UP2.0 and switch to HSFX4.1

All you gain from UP2.0 is two or three more planes than HSFX has

That some see as an positive

The negative is the UltraPack folks take MODs from HSFX and change the flight models without telling the orginal MOD makers

Stick with the orginal, in that UltraPack is basically a re-packaging of HSFX with a couple of extra planes and a bunch of tweaked FMs

...bollocks, you obviously haven't had a closer look at UP.... :roll:
