Indochina, it seems like you have posted several flaming posts in relatively short time here. Comments like this can easily be disproven. So if you want to continue to be in this forum, please make some effort to actually read up on threads first. It's just last couple of pages that we've talked about how J-10B's first batch is at least 40+ units.
