Sorry for the implied sarcasm,
I'll try and make it clearer what I am asking.
What I meant by Pure-Jet was Jet as opposed to turbo-prop, you know jet engines, but driving propellors!
As the the difference between Pure-Jet and Jet, Kamelf Hucker, I do not have a freak'n clue what you are talking about. But I am prepared to be enlightened.
