襟翼舵机安装
Flap servo installation
注：调试襟翼收紧后，舵机的行程量再适当的退一些，让襟翼适当的松一点，
以免憋舵，损坏舵机。
Note: After the adjustment flaps are tightened, the stroke of the steering gear
should be properly retracted, and the flaps should be loosened appropriately
to avoid jamming the steering gear and damaging the steering gear.

主机翼与机身对接
Main wing and fuselage docking
①主机翼使用的是φ30x1380mm碳纤维管将两个机翼对接到机身上。
②如图2红箭头所示，螺丝规格：M4x25mm内六角螺丝，对应的螺丝孔是在机翼上。
机翼机身对接到位后使用3.0六角螺丝刀在机身里用适当的力拧紧，如图4所示。
③如图3红圈所示，机翼机身对接到位后，在机身下
表面有颗孔，用2.5六角螺丝刀插入，用适当的力拧
紧。
① The main wing uses φ30x1380mm carbon fiber tubes to
connect the two wings to the fuselage. ② As shown by the
red arrow in Figure 2, the screw specification: M4x25mm
hexagon socket screw, the corresponding screw hole is on
the wing. After the wing fuselage is docked in place, use a
3.0 hex screwdriver to tighten it from the inside of the
fuselage, as shown in Figure 4. ③ As shown by the red circle
in Figure 3, after the wing fuselage is docked in place, there
is a hole on the lower surface of the fuselage. Insert it with a
2.5 hex screwdriver and tighten it with appropriate force.

Docking the horizontal tail and the fuselage
①如图1所示，将水平尾上的孔位对应机身上的碳纤维管插入，并对接到位。
②对接到位后，在水平尾下表面有两个孔（图中绿色箭头），用2.5六角螺丝
刀插入，用适当的力拧紧即可。
① As shown in Figure 1, insert the hole on the horizontal tail corresponding to the
carbon fiber tube on the fuselage, and connect it in place.
② After docking, there are two holes on the lower surface of the horizontal tail (the
green arrow in the picture), insert it with a 2.5 hex screwdriver, and tighten it with
appropriate force.
