Quick Answers
Mechanics FAQ
Can you motor lock a Motor 2 in Plane Crazy?
Motor 2 locking is not possible in Plane Crazy, as motor locking mechanics only function using standard Motor blocks. Read the guide
Why does a custom rudder fail to turn in Plane Crazy?
A rudder will fail to move if any wing edge touches the hull during placement, which causes the physics engine to weld the pieces together. Read the guide
What does mouse control do on a Plane Crazy ball joint?
Enabling mouse control forces the ball joint to automatically track the player cursor, allowing for one-block turrets and high-agility jet tracking. Read the guide
