1.for airplane engine, How do I know the Bypass ratio when it is not even a ratio.
2. if there's 2 wings put in together, will they produce twice more lift or only if the only parts touching the air?
3.How do I make the Nuclear Engine more efficient, almost all my possible ways(except cheats) would just run out within seconds
4.Is there any any possible way to add mods to mobile?
And that's all. . . .
if you can help, thank you
