75 tons was ridiculous and honestly we never should have released such a bulky monstrosity in the first place. The new Deliverator Slim is now a mere 73 tons!
Turns out the amount of water produced from melting ice is 20, and the amount of water needed for fuel and oxidizer is 10 each. So instead of cycling between fuel and oxidizer with a water override, we can just cycle to run one of each recipe. No storage tanks necessary!
R&D was also informed about a width issue with previous designs. With the removal of the water storage tank we were able to dramatically improve aerodynamics. For very brief periods of time while flying towards a planet, this sucker can hit 50km/s!
You could remove one more tile by taking out the light next to the turret. That'd bring it down to a slimmer 72 :D
Edit: Just saw from your other post that the lights are integral to the ship operation. Ignore me.
I wonder if I could tie the Blinky Logic to an existing combinator and remove the dedicated timer combinator
