Oistein you'll be fine doing it that way. I just got back form the field and fleww mine for the first time today. I ahev the Axi 5330 for motor also. What you may to do is the fly it and see you may need to change the wings, by bring the tailing edge dowm from the marks on the fuse. I had to and my friend has the E-Motion had to do the same on both off his plane. As for the C.G. we started where it call for and work back some. we flew it with True R/C 10s 5000 and had to put the back off battrey about 1 inch beong the battery tray. I'll check some more for you and get back to you. Good Luck. By the way Yes it flys Great.
