Advanced Fuel Flow help needed for Asymmetric rocket

[Halsfury]

Most people after downloading 0.23 probably broke out the RAPIER engine to test it out, I didn't however, because I had a cunning plan to build something delicate with the new tweakables system.

Here it is:cool:

It flies excellently, doesn't have a very complex start up procedure and is 121 parts last I checked.

Problem:

The Main tank fuel must be monitored closely by the pilot or the shuttle will being a spin of death around it's new COG (centre of gravity), once this happens death will certainly follow for the whole crew.

The Challenge:

Keep the fuel ratio in the 2 orange tanks (which make up the external tank) exactly the same throughout the flight using fuel loops.

What I would really like is if someone could rig it so that the fuel drains from both tanks at the same time and at the same rate

NOTE: I know that fuel adjustment may be necessary but if there is a way to take some of the micromanagement out of it,that would be great

Also I'm not releasing the craft file because a test rig with a 2 tank external tank and an engine should do fine in replicating the fuel flow dynamics at play here.

Separate the tanks with the blue stack separator to prevent fuel flow between them and place fuel lines on both tanks, Im not sure if it would work but it might

Ok thanks I'll give it a go

Use any stack separator between the tanks (might have to run extra struts between both tanks and the orbiter as well to maintain structural integrity during liftoff) then run a fuel line from each tank to the orbiter.

So you have:

Top ->Orbiter

Bottom ->Orbiter

(tested and working in .22)

A truss separator would work as well, use a single short and then eight struts to brace the two tanks, thus negating the risk of accidental separation.

You can also use the small 1x1 structural panel to separate the two tanks
