Hi All ! Tks for the reply , the grip got some hot , but not very hot , and battery got some warm too , so hope it is normal , and did happen the motor not turn while making firing too , but only happen once , does anyone have the same problem like mine too ???
This is my own build gun , fully metal but the thing is the motor is not really straight down , there is a bit like 2deg off the grip when you see it from the hole of the nut , so any solution ???
