I've seen pics of formula 1 racing where after a crash, the driver is trying to get away from flames engulphing him - the video does not pick up the blue flames.

I've also seen exhausts burning blue but at the last part of the flame they start to flicker yellow.

Interesting topic. In my mind I'm beginning to rationalize briefly yellow turning to blue as the system heats up but that is purely a guess by me and I'm sure Oleg will have the definitive answer after seeing all the info being brought forward.

Yet another video - watch for the colours at approx 30 seconds:

Best vid I could find of MH434 a mkIX spitfire with type 66 Merlin engine. From 5.35 to 6.25:

Any kind of visible flame on startup is very unusual unless this is due to overpriming of the engine. A spitfire in good condition will start with less than one turn of the prop. They can throw out quite a bit of smoke though for a couple of seconds. See here, a mk1a:

The flames matching the firing order is very impressive!

Maby this should indecate to people that Oleg and team are ontop of things:

"We have original table of the exhaust colors by which British crew were need to define is in good or not so good conditions the engine before the flight..."


Meaning maby Oleg and team have more than one colour to play arround with depending on situation.


So maby we could go back to the orginal question:

"My question to community: isn't it too yellow? Maybe to add a bit red color in a mix with yellow? It is tunable really, so I would like to listen suggestions"




Amazing how difficoult focusing on the issue at hand can be for some.

sorry for my bad very very bad english

in all benzine engine the exaust flames is blue, benzene vapor create those color, but see yellow/orange flames is caused to "return of flame" (in italiano si dice ritorno di fiamma in inglese non ne ho idea!) this "return of flame" is determined from a not complete combustion of the mixture in the cylinder

I must say it is nice to see that the hangars are weathered and old looking.

A question about the presentation video 2 weeks ago - will we see English train stations? The one shown with British vehicles passing nearby is Foo'bar's German station (and can be seen on his site).

Yes, I know it does in the real world. I was just wondering if this will be modelled in SoW.
