A Plane Crazy gyro core—frequently called an M2 core—is an orientation and aiming mechanism in the Roblox physics sandbox game Plane Crazy (developed by Plane Crazy Developers). It pairs one or more Gyroscope blocks with Motor 2 components to lock rotational axes and force an entire machine, turret, or Aerial Nuisance Object (ANO) to track the player's cursor. Because assemblies driven by Motor 2s exhibit massless physical behavior in the game engine, gyro cores provide virtually instantaneous turning response across combat and precision builds.
Gyroscope Block Settings and Default Values
The foundation of any gyro core is the Gyroscope (or Gyro), a 1x1 functional block designed to maintain directional orientation. The block includes adjustable physical parameters and allows builders to toggle individual rotational axes by interacting directly with the colored nodes on the block surface.
| Setting | Default Value | Minimum | Maximum | Function |
|---|---|---|---|---|
| Power (P) | 500 | 100 | 20000 | Dictates the overall rotational power output of the block |
| Damping (D) | 500 | 100 | 3000 | Restrains unwanted vibration and oscillation |
| Strength | 30 | 0 | 3000 | Dictates torque applied to correct orientation |
| Max Angle | 90° | 0° | 90° | Maximum angle deviation the gyro can handle |
| Toggle Key | H | — | — | Toggles the active state of the gyroscope |
| Set Rotation | N | — | — | Sets the block's current angle as its new baseline rotation |
| Powered | ON | — | — | Toggles whether the block draws active power |
| Apply At Center | ON | — | — | Applies stabilization force directly to the center of the connected assembly |
The Gyroscope's stabilization axes are relative to the block's physical placement orientation rather than the global build grid:
- Green Axis: Controls the yaw rotation.
- Blue Axis: Controls the pitch rotation.
- Red Axis: Controls the roll rotation.
Disabling specific colored axes tells the Gyroscope to ignore movement on that plane. For example, disabling the red and blue axes leaves only the green yaw axis active, preventing unwanted rolling while allowing horizontal alignment.
How Gyro and Motor 2 Cores Work
In community engineering terminology, a gyro core functions as an axis lock. When builders connect Motor 2 units to an axis constrained by a gyroscope, piston lock, or void assembly, the free-floating section of the machine turns to align with the cursor.
Community documentation notes several distinctive physical traits of M2 gyro cores:
- Massless Behavior: Assemblies mounted via Motor 2 components behave as massless bodies under the game's physics calculations, granting high maneuverability.
- Rigid vs. Non-Rigid Cores: Cores can be assembled in rigid or non-rigid configurations. Rigid cores generate higher, balanced torque. Non-rigid cores produce less torque and are prone to unbalance.
- Core Footprints: Gyro cores range from ultra-compact 1x1 (or 1x1x1.3) formats to 3x3 blocks, 5x3 layouts (historically the most widely documented standard in shredder communities), and 5x5 frames.
- Activation Requirement: Most M2 gyro cores do not automatically engage upon spawning. They must be activated by initiating a physics update—such as dropping the build from an elevation under gravity, bumping against the terrain, or briefly welding the build to the Motor 2s using TNT and detonating the explosive.
How to Build a 1x1 Gyro Core
While standard M2 cores often require a 5x3 or 3x3 envelope, third-party build guides outline a compact 1x1x1.3 variation that uses angle locks to compress Motor 2 components into a single-block footprint.
- Place the Gyroscope: Lay down a base Gyro block with your desired stability settings.
- Mount the First Motor 2: Attach a Motor 2 directly to the gyro. Set the Motor 2 to maximum speed and maximum torque, and assign an active toggle keybind.
- Attach an Angle Lock: Place an Angle Lock set to a 90-degree angle. Configure this angle lock to be invisible and non-collidable. Position it so that it locks the subsequent Motor 2 directly into the first Motor 2, folding the assembly into a compact profile.
- Add the Second Motor 2 and Zero Lock: Attach the second Motor 2, followed by a zeroed-out (0-degree) Angle Lock.
- Secure the Base Block: Add non-collidable filler blocks, and attach your main machine's mounting base to the assembly. Ensure you do not weld structural blocks across the rotating joints, as rigid cross-welds freeze the core's movement.
Gyro Cores vs. Ball Joint Cores
While M2 gyro cores remain the standard for high-speed cursor tracking, builders also employ Ball Joint cores (or hybrid combinations) depending on the vehicle's role.
| Feature | M2 Gyro Core | Ball Joint Core |
|---|---|---|
| Turning Speed | Extremely fast and responsive | Noticeably slower turning rates |
| Torque Profile | High torque in rigid builds | Naturally high structural torque |
| Durability | Vulnerable if exposed | High physical durability and compact shape |
| Rotation Scope | Rotates attached parts around the core | Rotates the entire vehicle body |
| Specialized Parts | Primarily rigid linkages | Compatible with suspensions, pistons, and ropes |
| Aiming Range | Driven by Motor 2 angles | Features mouse control with vertical elevation |
According to community build testing, ball joints utilize the internal mouse control property (often configured at speed 50 and a max angle setting of 1) to seek cursor position. However, ball joint assemblies tend to introduce unintended roll and tracking wobble. Builders mitigate this by mounting an upright Gyroscope with its red (roll) and blue (pitch) axes disabled, and by elevating the pilot camera to a third-person perspective so the mouse reticle does not intersect the joint's collision zone.
In high-durability PvP designs, players occasionally construct hybrid cores that rely on a gyro core for primary high-speed tracking, with an onboard ball joint toggled on as a secondary backup if the gyro is destroyed.
Practical Applications in Plane Crazy
Gyro cores appear across several distinct vehicle archetypes within the game:
- ANO Shredders: Aerial Nuisance Objects rely on gyro cores to rotate their cutters, thrusters, and armor directly toward target aircraft without conventional flight surfaces.
- Tesseract Omnis: Omnidirectional shredders equipped with forward-facing arms use internal 1x1 or 5x3 gyro cores to stabilize the main chassis while blade motors run continuously.
- Magnetic Railguns: Player-built railguns utilize a gyro core mounted behind the accelerator barrel. By fixing the magnet array (configured to repel TNT projectiles or cutters) onto an M2 gyro core, the gunner can aim the weapon in any direction independently of hull movement.
Frequently Asked Questions
Why is my Plane Crazy gyro core not turning after spawning?
M2-based gyro cores require an initial physics impulse to activate. You can activate the core by letting the build drop from a sufficient height, bumping the hull into the ground, or detonating a temporary TNT block welded between the build and the Motor 2 assembly.
Which axes should I turn off on my Gyroscope?
It depends on the core's intended movement. If your build needs to rotate horizontally toward targets without rolling over, keep the green (yaw) axis enabled and click the red (roll) and blue (pitch) buttons on the Gyroscope block to disable them.
What causes a gyro core to lock up or spin uncontrollably?
Lockups typically occur when structural blocks are accidentally welded across the moving segments of the Motor 2. If the build spins violently or jitters, ensure the Gyroscope's Damping (D) is sufficiently high (default 500) to restrain oscillation, and verify that your Motor 2 keybinds are toggled on.
