Research Hover Engine

Research Hover Engine is a research item that unlocks Hover Engines, which are required to produce flying drones. It opens the way to additional robot types and is a key step if you want to expand into airborne automation.

Its research cost is listed as 50 / 50 / 50 / 20, with a time cost of 20 seconds per item. Once completed, it enables access to Hover Engines in the production chain, making it an important technology gate rather than a standalone upgrade.

Because flying drones depend on Hover Engines, this research is most valuable when you are preparing to move beyond ground-based robotics. If your factory plan includes aerial transport or advanced drone production, researching this early helps avoid a bottleneck later in the logistics chain.
