Z-10 has some engine issues but in couple of years China will make an update in the engine They will become more lethal in future Z-10 already has a firing range of 10km Pakistan is already interested in a heavy helicopter like Mi-28Z-10 is underpowered . It's like the Tigre but less sophisticated.
I would remove Z-10 and go for a light scout helicopter like the MD-530G or AH-6I
