The TR-18A Stack Decoupler is a Decoupler that allows for staging rockets vertically and in sequence. It is also the only stack decoupler in the demo version of the game.

Usage

The TR-18A adds a stage to the rocket and when activated will jettison anything attached to it. Unlike the TR-18D, the TR-18A remains attached to one side of the rocket - the side facing away from the arrow on the decoupler. It is primarily used for jettisoning spent stages or drop tanks with a 1.25m node.

Product description

The TR-18A Stack Decoupler is equipped with a (hopefully) small explosive charge, that will sever the structural linkage between itself and whatever it's connected to. Painted on its sides are handy arrows indicating which side will detach.
