I know i don't have the knowledge to fly it!

Thing is i have little choice, i have flown small 3 channel electric foamy park flyers and i know i am totally out of my league with this plane. trust me with the money and time envolved i really don't want to go home with a pile of splinters but i have little other choice. I'm looking for any assitance i can on what i should do on my maiden flight other than crash spectacularly.
