  1. 1.0 1.1 The mass and drag are from the part config, but the game handles it as physicsless.

The Cubic Octagonal Strut is a very small, cube-shaped strut assembly. It has stack nodes at either end, but can mount to any surface. This makes it crucial for building non-standard assemblies.

Currently[outdated], the Cubic Octagonal Strut has "PhysicsSignificance = 1", making it a part with no mass or drag.


Cubic Octagonal Struts can be placed under the Rockomax Jumbo-64 Fuel Tank and 1.25 meter engines can be placed on the struts, which using symmetry creates "engine clusters" of up to 5 engines. The Cubic Octagonal Strut is also used to stack intakes. One stacks multiple struts, not using the part snapping feature, and then places intakes between the struts. This allows a large quantity of intakes to mount on a much smaller surface area (see Scott Manley's Airhog). In addition, it allows non-radial intakes to be placed on surfaces rather than the ends of fuel tanks and other parts.

Product description

Now, with advances in technology, StrutCo brings you the Cubic Octagonal Strut - it's like a regular Octagonal Strut, but in the shape of a cube!
