After a flight, the spaceplane is refitted with jettisonable fuel tanks and jet engines/electric fan blade motors depending upon the planetary body. I've spent weeks building a beautiful reusable space plane capable of sea level landings on Eve and Laythe and descent to 0 meters (sea level) on Jool. In some cases, your craft will bounce off the. Slowly move towards the docking port, and when you are within 2 meters, turn off SAS and RCS and let the port magnets take over. Press R to activate RCS, and use the translation keys to move your craft towards the docking port, and rotate it to align with the other craft's port.

At first I thought I had done something wrong, but I have built two very simple and seemingly identical ships that demonstrate the problem.Toadicus’ TweakableEverything doesn’t make everything tweakable, but what it does may scratch your tweaking itch even more than stock tweakables can. Now I am finding that, even though crossfeed is enabled on both docking ports, the engines won't draw fuel from tanks across the docking ports. I've meticulously built a mothership with robotics to fit the parts on the spaceplane.

And yet, while the orange ship performs as you would expect (fuel drawing evenly from both tanks), the white ship will only draw fuel from the bottom tank. You can see that on each ship both of the docking ports have crossfeed enabled. In KSP, each part has zero or more PartModules associated with it.Take a look at the pictures in the links below: The ships are identical (other than the paint scheme), right? Notice that they both have an upper and lower fuel tank connected by docking ports. This includes part modules in stock KSP, and those added by mods. For docking port parts, this reference frame is not necessarily equivalent to the reference frame for the docking port. For this reason, Nate Simpson, Creative Director of KSP 2 informed the community last week about the decision of releasing KSP 2 in 2022 instead of fall 2021.crossfeed ¶ Whether this part.

Lastly, the spaceplane undocks. Then the connection to the robotics is jettisoned using couplings. Then the robotics rotate the new modules in place and the docking ports take hold. Of course, once the plane docks with the mothership, it is all one vessel from KSP's perspective.

It seems that the docking ports leading into the vessel containing the 'control from here' point need to be primary for things to work. Once I do so, fuel flow works again.
