not just the hop-up actually. you could first do the air-tight of hop-up.
if you found it still unstable, it might not be solved because there is no guarantee-linear-movement of the piston.
you would find there is no guide for the piston thus the air-tight of the piston-head is weak thus make the power unstable. 作者: tinyau1134 時間: 2-1-2011 00:09
