FTE-1 Drain Valve and Stratus-V Monopropellant Tanks

[antipro]

The valve can't be attached on both Stratus-V Roundified/Cylindrified Monopropellant Tanks.
These tanks can be drained only if a valve is attached on another non-radially mounted RCS Fuel Tank or on a Pod.
So how do I drain the Stratus-V tanks without necessarily having another RCS tank or a Pod?

The old way it seems: expend it with regular RCS thrusters.

And yes, it is way less practical than a drain valve.

@antipro I have done this kind of attachment (with docks) via craft file editing and simply placing an appropriate 'link =' directive.

I came across your note while trying to determine whether drain valves work at all with MP. 

Let me know if you still want to proceed with this.  I'll make a subassembly for you.

A simple ModuleManager patch will allow you to attach the drain valve (and any other radial mount parts, like batteries, antennas, solar panels) to the radial MP tanks.

@PART[rcsTankRadialLong,radialRCSTank]
{
    @attachRules = 0,1,0,1,1
}

@Hotel26 I have a feeling any weirdness you're having is because you're doing it with save file editing, which is dodgy at best.  I just tested the above patch and it works fine.  And yes, the valve does work with ore (not that it has to - you could dump that already)

No, my problem was I simply didn't punch the button that says "drain MP or not" .  I don't recall you needed this for LF/OX, so why for MP?  Anyway, I got past this soon after writing the note.

The advantage of a drain valve for ore is that you can bleed some of it, for ballast control.  Rather than Jettison [Entire] Contents.

Thanks for weighing in with your solution!

So, let me ask a practical question.  I've avoided Module Manager as if it's Black Magic.  Whereas, if it were documented somewhere...    Do you have a pointer?  I'd also like to see definitive doc on config files, as those are definitely useful.

Ah yes, that can get you.  And yes, you do need it for LF/OX.  It's pretty vital for those switches to be there, otherwise you would be forced to empty an entire tank even if you just want to dump, say, the oxidizer.

You could try the wiki.  https://github.com/sarbian/ModuleManager/wiki/ (which is linked to in the MM thread's OP )

Although most of what I've learned about it came from looking at existing patches and then referencing what I saw with the documentation.  I'm basically incapable of learning how to do things just from reading the directions, I have to see examples.
