Friday 2010-12-10 Dev. video update and Discussion

[MD_Titus]

i like the wealth of knowledge that is displayed here sometimes. from a brief video and question on flame colour we get a huge discussion on possible engine states etc, actually learnt quite a bit. so has the question been answered with another one - will the flame colour reflect different levels of fuel/air mixture and engine condition, and if so, what are the factors at play in the video to give this particular flame?
