Wing

Set the half wing in a certain angle and trim the height of bottom to wingtip (64mm), sand joint

place in vertical state.

Tape the joint on the bottom.

center line and 45mm from the leading edge.

Using a 0.8mm straight stick though the hole on the horn to check the aileron horn position

when glue it.

6

Drill the hole on the center line position as the servo wire channel

Dig the three holes (dia.7.0mm) as the size above. Cut the plastic tube to the suitable height.

Tape the aluminum belt upper surface and tight plastic tube with screw then through the carbon

boom.

Measure the Carbon boom in the vertical place with the wing.
