Hypergolic engines and fuel

My suggestion is to add hypergolic fuel and engines with this fuel to the game.
Hypergolic fuel is a very simple system, I think this could be used in orbital maneuver engines, like in the space shuttles, the engines can have the thrust configured, like in other types of engines, it could be used in larger engines, as in Chinese rockets that use hypergolic fuel, Which could be used both outside and inside the atmosphere.
Engines with this fuel would be cheaper, as they would not require many components. The engines would be configured for different uses in the construction area.
Another engine could also be added to the construction area, with a simple design, I hope I'm providing some useful suggestions for game development, and I hope that the addition of this fuel, along with hypergolic fuel engines, will open up new possibilities for building.
