Plane Crazy Car Tutorial: Builds and Steering Systems

Plane Crazy allows players to engineer custom ground and hover vehicles using Roblox physics, modular motors, and aerodynamic parts. Constructing a reliable car requires an understanding of chassis layout, engine keybinds, and wheel steering mechanics.

Whether you want a high-speed Formula 1 racer, a balanced hover vehicle, or advanced mechanical steering linkage, the following guides break down the exact parts, settings, and configurations tested by the community.

How to Build an F1 Race Car

This Formula 1 build is designed for high-speed straight-line acceleration and sharp cornering using standard wheels and rocket propulsion.

1. Engine and Chassis Base

• Place a Super Rocket Engine directly on the chassis centerline. In its configuration menu, set Increase Power to 1 and set On/Off Only Mode to True.
• Frame the Super Rocket Engine using standard blocks in a U-shape, adding a single block behind it.
• Add two sets of wedges on each side that rise two blocks high.
• Place two blocks at the rear extending into a 1x3 wedge, followed by a second 1x3 wedge stacked on top.
• Place the Main Pilot Seat in the center pocket created by the surrounding blocks and half-wedges.

2. Aerodynamic Nose and Wings

• In front of the pilot seat, place a Half Wedge Down 1x2 from the Half Blocks category.
• Position two blocks underneath and two blocks in front, followed by a half wedge and a row of three half blocks to form the front bumper.
• Add Half Wedge Ups to shape the front into an aerodynamic slope.
• Along the body sides, attach Triangle Wedge 1x2s pointing backward next to the 1x3 wedges, followed by Triangle Wedge 1x3s along the outer chassis. Finish the side profiling with Half Block Down 1x2s.

3. Active Spoiler with Motor 2

The rear spoiler tilts on activation while engaging extra forward boost:

• Place support blocks under the rear deck and attach an upside-down half wedge, framed with half blocks and upward-facing half wedges.
• Mount two Delta Wing 1x1 pieces on the ends.
• Mount two Motor 2 units with their yellow cylinders facing backward and gray bases facing inward.
• Left Motor 2 Settings: Set Backwards to 1, leave Forward on an unused keybind, set Max Angle to 30, and toggle Servo on.
• Right Motor 2 Settings: Set Forward to 1, leave Backwards on an unused keybind, set Max Angle to 30, and toggle Servo on.
• Connect both motors across the gap using a Wing Panel 1x3.

When pressing 1, the spoiler angles down by 30 degrees while your Super Rocket Engine triggers forward acceleration.

4. Wheels and Paint

• Attach four standard wheels into the open wheel wells.
• Front Wheels: Keep standard controls—W for clockwise, S for anti-clockwise, D for left, and A for right. Set Speed to maximum.
• Rear Wheels: Configure W for clockwise and S for anti-clockwise, but toggle Steering Off.
• For a standard race aesthetic, set body blocks to RGB (60, 60, 60), highlights and wing tips to palette color (0, 255, 255), and tires to (20, 20, 20).

How to Build a Hover Car

If you prefer terrain-independent travel over wheeled chassis friction, hover cars utilize Hover Thrusters combined with jet and rocket thrusters.

1. Floor Layout and Base Framing

• Start with Half Block Wedges placed on the ground, leaving a spacing of 4 blocks between corners to create a rectangular perimeter.
• Fill the front and rear spans with wedges and half-wedges to smooth the edges.
• Lay 1x7 beams and 1x4 beams down the center, filling gaps with half blocks so the underside is completely flush.
• Mount the Main Pilot Seat centrally on the chassis floor.

2. Thruster Propulsion and Turning

• Mount a Rocket Engine directly behind the pilot seat facing forward:
  • Increase Power: W
  • Decrease Power: S
  • On/Off Only Mode: True
• Add a Jet Engine pointing forward:
  • Increase Power: S
  • Reverse Thrust / Increase Power: W
  • On/Off Only Mode: True
• Place two lateral Jet Engines at the rear for steering:
  • Left-Facing Jet Engine (exhaust pointing right): Set Increase Power to D, On/Off Only Mode to True.
  • Right-Facing Jet Engine (exhaust pointing left): Set Increase Power to A, On/Off Only Mode to True.
• Cover the rear engine bay using Disconnectors configured to disconnect on keybind W, which shields the internal engines while preventing block conflicts.

3. Hover Thruster Setup

Lift the car up by one block and mount Hover Thrusters beneath each corner pad:

• Increase Height: 1
• Decrease Height: 2
• Speed: 5
• Drag: 12

Setting the drag to 12 prevents the vehicle from drifting unintentionally when you release WASD inputs. If the hovercraft tilts front-to-back during test runs, replace solid canopy blocks with Helium Blocks along the roofline until the center of lift balances out.

Mechanical Steering Linkage Guide

While standard Plane Crazy wheels have built-in steering toggles, building custom mechanical steering using motors and rods allows you to control slip angle and handling characteristics.

Suspension and Motor Layout

• Place horizontal motors attached directly to the wheels. Set them to unpowered if building a Rear-Wheel Drive (RWD) vehicle, or powered if designing Front-Wheel Drive (FWD) or All-Wheel Drive (AWD).
• Attach vertical motors above the wheel hub to act as pivot points; leave these unpowered.
• Connect steering tie-rods between the wheel hubs and central powered steering motors.

Steering Geometry Types

Car Stabilization with the Gyroscope

Found in the ⚙️ parts tab (limited to 200 per save file), the Gyroscope operates as an orientable stabilization anchor. It prevents light builds, hovercraft, and high-speed racers from flipping over.

Gyroscope Settings

• P (Power): Controls how aggressively the gyro forces the vehicle toward the target orientation.
• D (Damping): Reduces oscillations and wobbling when the gyro corrects vehicle rotation.
• Fixed Rotation: Keeps the gyro locked to a fixed orientation regardless of player input.
• Apply at Center: Applies stabilization force directly to the build's center of mass.
• Axis Disabling: Clicking the red, green, or blue buttons on the physical Gyroscope block toggles pitch, roll, or yaw constraints off.

Using Gyros for Alternative Steering

You can turn ground vehicles using a Gyroscope instead of wheel turning angles:

1. Mount a motor pointing vertically upward anywhere along the chassis centerline.
2. Place a Gyroscope directly on top of the motor.
3. If using Motor 1, configure the backward key to A and the forward key to D.
4. If using Motor 2, set A as backward, D as forward, and toggle Servo on. Community wiki documentation notes that Motor 2 setups may experience wobble compared to Motor 1.

Frequently Asked Questions

Why does my car veer or spin out when accelerating?

If your car uses rear rocket or jet engines, ensure the propulsion block is centered on the chassis. For wheeled vehicles, verify that rear wheels have Steering Off toggled. Rear-wheel steering at high speeds reverses directional input and destabilizes the vehicle.

How do I prevent my hover car from floating away?

Set your Hover Thrusters to a controlled height setting (such as Increase Height 1 and Decrease Height 2) and increase the Drag value to 10 or 12. Without sufficient drag, hovercraft retain forward and rotational momentum indefinitely.

Which steering setup is best for tight turns at low speeds?

Standard Ackermann steering is best for low-speed maneuvering and road vehicle builds. Because the inside wheel follows a tighter turning radius than the outside wheel, angling the steering linkage behind the axle reduces front-tire dragging.
