Alye,
You won it? Congrats my friend. I would call BVM to see if they had any, if not call www.pspec.com, they handle BVM engines now.
However, thereisn't much to know about them. Get it started and set the mixture like you would on any other engine, except they have no needle valve. You will need a BVM in-flight mixture control (operated through a servo). The idle set screw is extremely sensitive, do not touch it, do not even stare at it for too long.
You will need a BVM puffer pipe. I think I can get you one cheap. I paid $50 for mine brand new.
You will also need a BVM pipe retainer, a must have and you will most likely use it with other ducted fan engines as well.
Let me just say, if you put that engine on the Hawk it will be extremely fast. Can't wait to see it.
