Differences in visual flicker-fusion rate between species is interesting. But I think it's a bit presumptuous to claim that time drags by 4x more slowly in a fly's reality, and that's why it can usually escape a giant hand falling from the sky. The fly escapes because it's quicker than you. It would probably be just fine if could detect motion at 60 Hz.
