Hello Oleg!

Nice job as always...I still would like to mention something, like in image 7:

one can imagine a mix of blue and yellow in flight, with yellow on the exhaust side but it would be only in a brutal transition in mixture adjustment from OK or poor to over rich...and you really would have to push your throttle very violently to its stop, and even then, on a fuel injected 109, I do not believe it would happen...

So my idea if you would like to keep it simple would be to have three flight exhaust flame states:

1) normal/poor mixture: blue regular sized flame, and - if possible, one day! - whitish exhaust strain on paint (sure sign you are running generally too poor)

2) over rich: blue on exhaust side, with yellow end regular sized flame (the opposite of the 109 image in terms of color order), brown exhaust strain

3) much too rich: yellow flames a bit irregular, occasional misfires, again if possible, blackish exhaust strain on paint (no less sure sign you are running generally too rich)

and at startup, in a random way or on record of overprime if existing, big flames, before normal functioning.

Generally no mix of blue and yellow if yellow is on exhaut side: physically difficult to imgine in a steady state...

I would like to apologize in advance if this comment still resembles nitpicking!
