I started on Ftb infinity after I was done messing around in ftb monster.
In monster I could get creative flight as early as I got my first steam engine because the costs to create advanced genetics lab and process bat dna were minuscule. But even if I didn't go for advanced genetics I still could still get creative flight with modular power suits.
Now it seems that none of those mods are in ftb infinity, so I'm a bit confused as to what should I use for flight.
I tried goggling it but all I could find is jetpacks (not creative flight) or something to do with quantum armor? (But that requires insane amount of resources)
