I developed these wings for my own action figures but they can be adapted to Lego and Technic creations. The pieces I used came frrom Technic and Bionicle sets.
Step 1: List of Parts
2 - angled beam (7 long, 3 angled)
1 - straight beam (6 long)
2 - #5 angled connector
2 - technic pin
2 - technic axle 3 with stud
2 - bushing
1 - soft axle (7 long)
2 - scalloped wings
Step 2: Pinion Sandwich
Begin with the axle with the stud, thread it through the angled connector, the outermost hole of the angled beam and a bushing to cap.
As a sandwich it would go:
Repeat for second set of wings
Step 3: Attached Wings
Attach wings to angled connector
Insert technic pins on angled beam where it will connect with your creation.
(Number and location of pins will vary)
Step 4: Adding Muscle
Attach soft axle (silver hose) to the inner ends of the angled connector
Step 5: Come Together
Attach the angled beam with the straight beam inbetween.
This can be attached to plates, bricks or in this case an action figure.
Push on soft axle for action.
Push down = Wings out. Push up = Wings in
Perfect for adding some action to your action figure or some flash to your creation.
