The HS300 ship construction regulations are the base for the modified HSX Series regulations. If you are planning on building a racer for Series 4, please read these first.

1. Competing spacecraft are expected to use components with a minimum size of 2x2x2 studs, and are limited to only one gyroscope component.

2. All participating spacecraft must adhere to a maximum functional acceleration limit of 333.33 studs per second squared (st/s²) across all axes.

   • 2.1. Functional acceleration refers to the acceleration of a craft when a movement key is pressed, not the acceleration shown in the 'Connected Stats' table.

3. Competing spacecraft must be larger than a box set with the dimensions of 6x4x18 studs. HS300 set maximum is 15x8x28 studs.

   • 3.1. This must be checked at normal orientation, where the control seat has zero X or Z rotation. 

4. All competing spacecraft must possess a minimum weight of 500 units.

5. Racers must have collisions turned on. 

   • 5.1. Parts used to access the control seat may be exempted.

6. All competing spacecraft must be outfitted with a discernible interior design element.

   • 6.1. This includes a seat, control method (stick/throttle, joysticks, etc), and dashboard/MFDs. Spacecraft must be operable should the player use FPV. 

7. Each spacecraft must conspicuously exhibit the official HS300 Championship class decal. The said decal can be retrieved from the
   #league-graphics channel in the HSRL server.

   • 7.1.  The class decal requirement necessitates clear and unobstructed visual identification from a distance (the decal must be legible when looking at the spacecraft as a whole)

8. All competing spacecraft are subject to a minimum standard of visual appeal. Engine boxes and the mere stacking of bare components solely for function are expressly forbidden and will result in a rejected time submission.

9. The front of the control seat must point towards the front face of the limiting box at all times (15x8). It cannot be manipulated by a servomotor.
