This ship was designed to be a minimalist take on what could reliably traverse the inner 4 planets, while using good design principles around utilizing the cargo space of the collectors, enforcing good fuel efficiency based on production rate, and being self-sustaining.
The design uses efficiency 2 modules to reduce power costs so that it can survive in Fulgora orbit. You will also want to research at least physical damage 5, in order to ensure the ship doesn't run out of ammo during the journey between planets.
When you first build the ship, you will want to temporarily turn on the pumps to get some fuel in the engines. You can set the Yellow Signal into the decider for the pumps to turn them on for a while, or just uncheck the enable condition on the pumps for a few seconds. Unfortunately there is no way to see the fuel contents of the engines to know they are empty using combinators.
Once they have at least a little fuel they are self regulating. The ship is cheap enough to build several of them to wander around the system moving items around.
The ship receives a Green Signal when it is safe and ready for departure. You can use this signal for your routes and interrupts.
