Rocket RailButton
Description
A rail button is a small button attached to the side of the rocket that allows the rocket to be guided using a rail until it is fast enough to be aerodynamically stable.
Usage
- There are several ways to invoke the command:
- Press the
Rail Button button.
- Select the Rocket → Launch Guides→
Rail Button option from the menu.
- Double click on a Rail Button object in the Tree view.
- Press the

Rail Button Shapes
Rail buttons have two general shapes:
- Round.

The round shape is the most common and is the simplest to manufacture in bulk. As the name implies, the button is round, with a groove that allows it to fit onto the launch rail. It may be glued to the main body, but is more typically fastened with a screw.
- Airfoil.

The airfoil shape improved on the basic round button by giving it a more streamlined shape. Similar to the round button, it has a groove that allows it to fit on the launch rail. Adding a fillet on the top edges has been shown to further improve aerodynamic performance.
