In a manner of speaking, you are asking for help putting your plane together... Which DF you use is up to you... etc.
What a crock... there are a wide range of DFs out there... customers cannot just throw any ol thing in the plane... they need to have a setup which lets the plane perform as designed!
You need to read posts more carefully... I NEVER once asked a question like, "how do I install the engine?" Such question would be asking NP to build my plane for me. Please go back and read my original reply asked for specifications, NOT a how to.
