Since HD/Fury and 2048 had these threads I thought its logical to have one for omega collection. This thread is for asking questions that can be easily answered without the need to post an entirely new thread about it.
For example if the question can be answered with a single post and there is no real discussion that can be developed from it, it belongs here.

So I'll kick us off by asking how come sometimes the exhaust trails change colour in some HD races? Sometimes fury ships have the blue exhaust trail while HD ships have red trails (and vice versa). Any ideas that can quench my curiosity?
