How come the engines on this craft flame out even with the rapier engines off?

[smjjames]

Maybe it's just me misunderstanding the new intake system, but anybody know why the jets are flaming out? Also, this was actually working fine earlier while testing it with TCA, but all of a sudden it decided to stop working.

edit: Oh. The reason why it was 'working' is because I had infinite fuel on the first time. Still, could someone help figure out how come the intakes aren't working like I think they would?

Are they actually connected with fuel, I don't think infinite fuel gives you intake air.

Do any of the engines work, or are they all not working?

Air in is affected by air speed and intake area, as well as pressure, so unless you're moving sufficiently those intakes may not be able to provide enough air.

All the intakes have some suction so planes can avoid flaming out at rest, but this varies from part to part, with the engine precooler and engine nacelle providing the most.

So if you fit some nacelles you should find you avoid flaming out.
