Why Build a Custom Center Console?

A center console is the nerve center of any realistic flight simulator cockpit. It holds radios, autopilot controls, navigation instruments, engine management panels, and other essential hardware. Off-the-shelf consoles often pinch fingers on cramped layouts or skip the buttons you actually fly with. Building your own lets you match the exact aircraft type you fly—whether it’s a Cessna 172, a Boeing 737, or a fighter jet—and gives you room for upgrades later. A well-built console transforms a desk-mounted joystick into an immersive workstation.

Step 1: Plan Every Inch of Your Console

Start by listing every control you need. For general aviation: radio stack, transponder, audio panel, backup GPS, throttle quadrant, flap switch, trim wheel. For commercial airliners: MCDU, autopilot mode panel, ECAS controls, engine start levers, overhead panel switches. A good rule of thumb is to plan for twice as many switches as you think you’ll need—you will find uses for them.

Measure your cockpit space. Draw the footprint on graph paper or use a free 3D modeling tool like SketchUp or Fusion 360. Include monitor or tablet cutouts for displays, clearance for hands during flight, and cable routes. Account for the console depth: too shallow and wires get crushed; too deep and you won’t reach the back switches. Aim for an angle of 15 to 20 degrees for the upper panels so they face you naturally.

Layout Ideas for Common Aircraft

  • General aviation (GA): Stack six-pack instruments vertically, radio stack on the right, throttle quadrant on the left. A 50–60 cm wide console fits most desks.
  • Airbus A320: Two MCDUs at the front, ECAM display in the center, overhead panel overhead (separate structure). A 70 cm deep console is typical.
  • Fighter jets: Side-mount throttle and stick with a small display panel. Width can be as narrow as 30 cm.

Step 2: Choose the Right Materials

Solid construction prevents wobble when you jab buttons. Here are the best options:

  • Plywood (12–18 mm): Cheap, easy to cut, strong. Birch plywood resists warping better than pine. Paint with matte black for a cockpit look.
  • MDF (medium-density fiberboard): Heavy and absorbs vibration well. Edges need sealing before painting.
  • Aluminum (1.5–3 mm): Light, durable, professional. Requires a drill press and deburring tools. Best for final panels or frames that hold heavy monitors.
  • Acrylic / polycarbonate: Good for backlit panels. Easier to scratch; use for switch labels.

For fasteners, use M3 or M4 machine screws with T-nuts for panels you need to remove later. Wood glue plus pocket screws create rock-solid frames. Do not rely only on wood glue for load-bearing joints like the base that supports a 15‑inch tablet.

Tools You’ll Need

  • Jigsaw or circular saw with a fine-tooth blade
  • Drill with an M3/M4 tap set (metal) or countersink bit (wood)
  • Screwdriver, hex key set
  • Sandpaper (80 to 220 grit)
  • Heat shrink tubing and wire strippers
  • Multimeter for testing circuits

Step 3: Build the Frame Base

Cut the side panels first. They establish the console’s slope and height. A typical design uses two trapezoidal side pieces connecting a flat bottom deck, a vertical front face, and a slanted top surface. Screw the bottom deck to the sides, then attach the front plate. Sand all edges round so you don’t snag wires or skin later.

Test-fit the top panel. If you’re using a monitor or tablet, cut the hole with a jigsaw after drilling a starter hole. Mount the screen using VESA brackets or custom 3D‑printed bezels. Reinforce the back of the monitor cutout with a strip of wood or aluminum so the screen doesn’t sag.

Installing Interior Shelves for Electronics

Leave at least 8 cm of vertical clearance inside for wiring harnesses, buck converters, Arduino boards, or a Leo Bodnar USB controller. Add a horizontal shelf halfway down to mount the circuit boards. Use standoffs to keep them off any metal surface that might short them. Drill cable grommets (20 mm diameter) in the shelf for tidy routing.

Step 4: Wire Everything in a Logical Order

Wiring is where most builders get stuck. Follow this sequence:

  1. Label every wire at both ends with a Brother P‑Touch or even tape and Sharpie. Use a consistent naming scheme like “ALT‑ON”, “NAV1‑VOL”.
  2. Group wires by function: radio stack wires together, autopilot wires together. This makes troubleshooting fast.
  3. Solder all connections or use crimp terminals for switches that might be swapped later. Avoid twist‑and‑tape—it will fail under vibration.
  4. Use a bus bar or terminal block for power (5V and 12V). Run thick gauge wires (16 AWG) from a USB‑C PD breakout board or a dedicated 12V power supply.
  5. Test each switch and LED before mounting the panel permanently. Use a multimeter to check continuity and voltage drop.

For USB‑based button boards (like those from Leo Bodnar or Arduino Micro), flash the firmware first. Map each button to a keyboard key or joystick button via free software like Joystick Gremlin.

Display Integration (Tablets & Monitors)

Many simmers use an old Android tablet or a smaller monitor (7 to 10 inches) as an MCDU or instrument display. Connect over HDMI or via a wireless app like Air Manager or FSX/Prepar3D with panel XML. Plan a cutout with a slight recess so the screen sits flush. Attach with VELCRO or a 3D‑printed bezel for easy removal.

Step 5: Surface Finish & Ergonomics

Sand the entire exterior to 220 grit. Apply a primer that sticks to your material (gesso for wood, self‑etching primer for metal). Paint with matte black or dark gray spray paint—matte reduces reflections in the glass display. Let each coat dry overnight, then lightly sand with 320 grit before the final coat.

Add comfort features:

  • Padded armrest: Glue a strip of EVA foam to the top front edge, cover with faux leather fabric.
  • Cable channel: Router or chisel a groove in the bottom deck to hide the main USB cable. Use a cable tie anchor to keep it from pulling out.
  • Anti‑slip feet: Attach rubber bumpers to the bottom so the console doesn’t slide on your desk during aggressive turns.

Step 6: Mount the Console in Your Sim

For desk setups, clamp the console’s base to the desktop with a C‑clamp or a simple wood stop block screwed to the desk from underneath. For full cockpit builders, attach it to a 80/20 aluminum extrusion frame or a wooden simulator cab. Use at least four M8 bolts into a crossbeam if the console holds heavy screens.

If you want the console to be removable for storage, install two quick‑release pins (like an AR‑15 takedown pin) on each side of the frame. That lets you lift the entire unit off in seconds without unbolting everything.

Step 7: Configure Your Sim Software

Once the hardware works, configure the software:

  • Microsoft Flight Simulator 2020/2024: Use the Settings → Controls → “Add new input device” to auto‑detect your USB button board. Assign functions per aircraft.
  • X‑Plane 12: Use the Settings → Joystick & Equipment → Buttons & Keys tab. X‑Plane sees each button press as a joystick button or keystroke.
  • DCS World: Use the Options → Controls → assign Axis and Buttons. DCS supports up to 128 buttons per device.

If you built an actual radio stack or MCDU, you may need a third‑party driver like FSUIPC to map hardware directly to sim variables. Start with simple button assignments before tackling rotary encoders or annunciator lights.

Common Pitfalls & How to Avoid Them

  • Too narrow: A console that’s less than 40 cm wide makes it hard to mount a radio stack and a display side‑by‑side. Measure your largest component first.
  • No access to the back: Build access panels on the back or bottom so you can reach wiring later. Use velcro or latch‑locking hinges.
  • Wiring spaghetti: Use adhesive cable tie anchors every 10 cm. Install a bundle of wires as a harness that can be unplugged at the console end.
  • Overheating electronics: If you have a Raspberry Pi or power supply inside, drill ventilation slots (or a 40 mm fan) pointing outward. Do not let the fan blow directly onto the back of a monitor—it will collect dust.
  • Incompatible button matrix: If you use a matrix scanner, some switches (like momentary on‑off‑on toggles) can cause ghosting. Use a dedicated encoder chip like the Adafruit MCP23017 for complex switch clusters.

Upgrading Later

One of the biggest benefits of a custom build is mod‑friendliness. Plan now for future expansions:

  • Leave room for a second display or a backup tablet.
  • Run an extra USB cable through the cable channel and coil it up inside for later use.
  • Install a removable faceplate that can be swapped for a different aircraft type. Use D‑sub connectors (DB‑15 or DB‑25) to connect the faceplate to the main wiring harness.
  • Add LED strip lighting inside the console, controlled by a 5V PWM signal, for backlight switches and panels.

Cost Breakdown & Time Estimate

  • Wood or aluminum: $15–$40
  • Switches & knobs: $20–$80 (depending on quality and quantity)
  • Wiring kit: $15–$25
  • USB button encoder: $10–$30
  • Paint & sandpaper: $10–$20
  • Display/tablet: $0 if reusing an old tablet, or $50–$150 for a new monitor

Total budget: about $100–$350 — far less than a pre‑built console that may not match your panels. Expect 15–25 hours of build time for a beginner, spread over a weekend or two. Wiring takes the longest; do not rush it.

Conclusion

Building a custom center console is one of the most satisfying DIY projects in flight simulation. You gain a perfect fit for your preferred aircraft, a durable frame that lasts years, and deep knowledge of how your controls interact with the sim. The process demands patience in wiring and assembly, but the reward—reaching for a real switch instead of clicking a mouse—makes every flight more immersive. Start with a solid plan, stick to good material choices, and test every circuit before final assembly. Your cockpit will thank you.
