Decouplers + nose cones now do crossfeed?

[Psycho_zs]

I've built a simple 3-stage rocket with no intended crossfeed.

Playing with new slanted nose cones, I've hooked them onto radial decouplers (it feels like they are made for each other, and separation in flight is perfect)

And the result was that my boosters drained core tanks dry. Both nose cones and decouplers have fuel crossfeed, and placing booster fuel tank in stack under the nose cone triggered 'reverse' asparagus.

...seems like a good reason for me to learn Module Manager syntax...

EDIT: fixed the code, now it works.

{
        fuelCrossFeed = False
}

No decoupler should allow crossfeed. If they did, would be definitely a bug. Mind uploading your craft and providing a link here for testing it?

There's a bit of odd behavior with radial decouplers and crossfeed: They will not crossfeed to tanks attached to them, but they will crossfeed through non-tank parts attached to them. I bet if you attach the fuel tanks to the decouplers rather than the nosecones the crossfeed issues will go away.

Yes, if you hang fuel tank on decoupler, it will not crossfeed. But I specifically wanted to put decoupler into slanted nose cone.

Any idea why my MM cfg does not work?

I noticed that today too. I made an air launched vehicle and saw that it was drawing fuel from the external tank through a TT-38K which was attached to a Mk 2 jet fuel fuselage.

ETA- Just ran a test on the launch pad. Attached to a rocket fuel tank there was no fuel flow through the TT-38K but when I stuck them onto a jet fuel tank there was fuel cross feed from the external boosters.

I think that's a different effect happening there, Reactordrone. Air-breathing engines ignore crossfeed rules and draw liquid fuel like monopropellant, draining all tanks evenly in a stage, with stage determined by the number of decouplers between the tank and the root part.

[Psycho_zs]

...got it! fuelCrossFeed property does not exist in decuplers configs, so I just needed to remove '@' from MM cfg.

I've fixed the code in previous message.

I think you're onto something. I was trying to make a Soyuz replica, and I had attached the nose cones to the decouplers to be more like the real thing. I couldn't figure out why the boosters were taking all the fuel from the core. If this hasn't been posted in the Support forum, it should be -- it'll be a confirmed bug quickly.
