✈️ P-51 Mustang (United States): step-by-step build

The shiny silver American fighter with a big four-blade propeller and a bubble canopy.

The P-51 Mustang was a fast American fighter with shiny metal skin and black-and-white stripes on its wings. This is a Technic-parts model inspired by it, not a real flying plane: grey beams make the polished metal, a yellow nose and blue stripes add the colours, and the propeller turns freely on its axle.

What you will learn

• Pins: Grippy or Smooth: Pins join beams together — some hold tight, some let things swing.
• Triangles Are Strong: A triangle cannot be squished — a square can.
• Centre of Gravity: Keep the heavy stuff low and in the middle and your model won't tip.
• Axles: An axle is a cross-shaped rod — anything on it turns together.
• Axles & Wheels: A wheel on an axle turns dragging into rolling.

Steps

1. Lay the floor of the fuselage: take a light grey 3×5 L-beam (short leg down: the tail-wheel leg), then push 1 black pin and 1 blue long pin in and press a light grey 11-hole beam onto them.
2. Lay the floor of the fuselage: push 2 blue long pins in and press a light grey 9-hole beam onto them.
3. Lay the floor of the fuselage: push 2 black pins in and press a yellow 3×5 L-beam (short leg up at the nose) onto them.
4. Add the roots of the wings and the tail: push 1 black pin in and press a dark grey 2×4 L-beam (short leg up) onto them.
5. Add the roots of the wings and the tail: push 1 black pin and 1 blue long pin in and press a dark grey 2×4 L-beam (short leg up) onto them.
6. Add the roots of the wings and the tail: push 2 blue long pins in and press a dark grey 2×4 L-beam (short leg up) onto them, then slide a dark grey 2×4 L-beam (short leg up) onto the blue pins that stick out.
7. Add the roots of the wings and the tail: push 1 black pin and 1 blue long pin in and press a dark grey 3×5 L-beam (short leg down: a landing-gear leg) onto them.
8. Add the roots of the wings and the tail: push 1 black pin and 1 blue long pin in and press a dark grey 3×5 L-beam (short leg down: a landing-gear leg) onto them.
9. Build the top of the fuselage, the cockpit and the tail fin: push 2 black pins in and press a light grey 11-hole beam onto them.
10. Build the top of the fuselage, the cockpit and the tail fin: push 2 black pins in and press a light grey boomerang beam (its bent end leans back: the tail fin) onto them.
11. Build the top of the fuselage, the cockpit and the tail fin: push 2 black pins in and press a clear 5-hole beam (the cockpit) onto them.
12. Build the top of the fuselage, the cockpit and the tail fin: push 2 black pins in and press a yellow 3-hole beam leaning back along the fin onto them.
13. Fit the propeller: push 2 black pins into the upright leg and press the long pin-axle block onto them.
14. Fit the propeller: push an axle into the block, slide on the black propeller beams and lock them on with a bush (the propeller spins freely on the axle).
15. Build the tailplane: push 2 blue long pins in and press a light grey 3-hole beam onto them.
16. Build the tailplane: push 1 blue long pin in and press a light grey 3-hole beam onto them, then slide a yellow 3-hole beam onto the blue pins that stick out.
17. Build the tailplane: push 1 black pin in and press a yellow 3-hole beam onto them.
18. Build the right wing: slide a light grey 7-hole beam onto the blue pins that stick out, then push 2 blue long pins in and press a black 7-hole beam onto them.
19. Build the right wing: slide a white 7-hole beam onto the blue pins that stick out, then push 2 blue long pins in and press a blue 5-hole beam onto them.
20. Build the right wing: slide a light grey 5-hole beam onto the blue pins that stick out.
21. Build the left wing: push 1 blue long pin in and press a light grey 7-hole beam onto them, then push 1 blue long pin in and press a black 7-hole beam onto them.
22. Build the left wing: push 1 black pin in and press a white 7-hole beam onto them.
23. Build the left wing: push 2 blue long pins in and press a blue 5-hole beam onto them, then slide a light grey 5-hole beam onto the blue pins that stick out.
24. Put on the wheels: push a 6-long axle through both legs and put a wheel on each end.
25. Put on the wheels: push a 3-long axle through the leg, with a wheel on one side and a bush on the other.
