Part configuration strutConnector

  1. 1.0 1.1 The mass and drag are from the part config, but the game handles it massless/dragless.

The EAS-4 Strut Connector is a part that allows linking two parts together, for greater structural strength and stability. Strut links are much more rigid than normal part connections, dramatically reducing wobble. Currently[outdated] it is a dragless and massless part.


Strut Connectors require a two steps for placement on a craft. After placing one end of the strut, click somewhere else to place the other end. Once both ends are in place, the strut is created. When on the second step, pressing the Delete or Esc key will cancel placement.


The Strut Connector is highly regarded by many spacecraft engineers as they help in constructing more stable spacecraft. Once both sides are connected, a structural beam is created to link both ends, allowing for sturdier (and heavier) construction.
