Pre-coolers and radial intakes?

[lewisd]

I'm playing with interstellar mod and B9 (with the 0.23.5 fixes), and I can't figure out how to make precoolers work with radial intakes. I have an SSTO with a B9 Sabre M engine, with the SABRE M precooler attached, and the precooler always says it's "offline". All my intakes are the "DSIX Diverterless Supersonic Inlet", which attach radially. I have them attached to the wings, not the precooler, but the precooler is attached directly to the engine. Is there any way to make the precoolers with with radial intakes?

A quick glance over Interstellar's code reveals that a precooler functions only for an intake that is directly attached to the precooler. It doesn't care about where the engine is relative to the precooler, so the intended usage is to put the precooler directly behind the intake.

I don't know the KSP API well enough to tell from the code whether intakes radially attached to the precooler will work, or if they have to be stack-attached. I've heard that they have to be stack-attached, but don't take my word for it until you've tried it.

From personally trying to make a per cooler plugin...

Yes interstellars precoolers must be stack attached to the front in order to work.

Hmm. It's hard to get enough intakes, with precoolers stack attached, to be able to fly at a good high altitude. As soon as I add some radial intakes for a bit more air, I start running into air temperature problems, and the engines overheat.
