All right, thanks; I think I'm wrapping my head around the general intended progression of building an EL base now: Phase I: Get a station into orbit around the target planet with a Workshop, smelter, ISRU refinery, and an orbital launchpad. Build a mining ship capable of going to the surface, mining Ore and MetallicOre and bringing them back to the station. Station refines those into RocketParts and liquid fuel to replenish supplies. Phase II: Build a survey station, capable of getting itself to the surface of the planet safely. Phase III: Survey station builds a Workbench (so it can make its own RocketParts; getting resupplies of RocketParts from the orbital station until that's built) and places it directly on the surface of the planet (that "not trying to launch it on a rocket" comment you made?), with RocketPart storage attached to it. Phase IV: Survey station builds a permanent mining rig for getting Ore and MetallicOre out of the ground, and Smelter/Refinery for creating Metal and liquid fuel. Now it's self-sufficient; able to make RocketParts on its own without resupply from orbital station, and can create items at survey stake locations. Phase V: Upgrade ground station to be a Workshop for more efficient craft creation. That look about what's intended for a "tech tree" for EL? So, where would the LaunchPad2 device fit into this plan; a replacement for Phase II's survey station? I'm not using Infernal Robotics, so using survey stakes is how I am placing "permanent" items (without wheels or engines). I suppose using a LaunchPad2 device, the mining rig of phase IV could just be made as a rover and rolled off the pad to clear room for the next devices. And then using KIS the wheels could be removed and recycled for the cleanest result.
