Before you start, you may need to cut off a part of the tail of your USB drive.

First, you need a USB flash drive with a caliber of 12*4.5mm. Second, you need strong quick-drying glue. Then, you have to insert the head of the USB flash drive into the bottom of the front fuselage of the F22, and make a line mark on the USB flash drive, then take it out. Finally, apply the strong glue to the slot of the rear fuselage, and then insert the tail of the USB flash drive into the rear fuselage, and the line scale slightly enters the slot. Wait for the glue to solidify, and then you can use it.

开始前，你可能需要把你的U盘的尾部剪掉一部分

首先，你需要一个口径为12*4.5mm的U盘。
其次，你需要强力快干胶。
然后，你要先把U盘头部插入F22前机身底部，并在U盘上做好划线标记，然后取出。
最后，将强力胶先涂入后机身插槽内，然后将U盘尾部插入后机身内，划线刻度略微进入槽口内。等待胶液固化后，即可使用。
