Tired of being stuck with limited propulsion options? Construct your own engine clusters!
In addition to their mount capabilities, all engines are surface attachable to facilitate cluster construction. There are four surface attachable adapters with built-in interstage fairings: 1.25m Ultra-Light Interstage Cluster Adapter (for landers), 2.5m Ultra-Light Interstage Cluster Adapter (for landers), 2.5m Cluster Plate, and 3.75m Cluster Plate. Along with these, there is also a large 3.75m mounted Expanded Cluster Tank with a large base for attaching clusters and carries fuel but cannot be stacked, and three node-based adapters cloned from the stock 2.5m-1.25m multi-adapters.
