I marked the CG by the book, and flew the maiden on a LiperiAir 6s 3300mah centered on the battery tray, and the second flight on a Liperior 6s 5000 about 2 inches back from the leading edge of the battery tray, and CG was good on both packs. Both flights were at 4 minutes, with alot of full throttle, and had 68% left on the battery. So the plane is very efficient, plus rcbattery.com lipos are quality packs, and pack the power needed for this type of plane. The plane flew much better on the Liperior 6s 5000mah, not just for extended flight times it seemed to be the right battery weight wise for this plane. I woukd strongly suggest going to this link if you have or thinking of getting this plane and get some of the Liperior 6s 5000's

While you have to glue the 3 nylon hinges in the rudder (I used 30 minute epoxy), and glue the wing side force generators on, the plane went together in minutes. Very straight forward build.
The finish on the plane is as always with FMS, very nice, the scheme on it is very attractive. I got alot of complements on it at the field.
The plane comes with 6 extra nylon ginger, assuming FMS did that to hinge the ailerons or elevator halves, because those are foam hinges out of the box, the 6 extra hinges are not enough to do the job. I ordered 14 of the hinges from the parts list, as it will take at minimum, 4 for each aileron and 3 for each elevator half to do it right. I would strongly suggest doing this as on my second flight I did a few snap type rolls with it and could tell after the flight that one aileron foam hinge was separating a little.
I like that the plane comes with a wood prop, on full throttle flying or maneuvers, under the power normally a APC prop would flex causing some loss of power and flight quality. The performance and the sound you get from a wood prop is awsome. It has a clean powerful sound to it. It would have been nice if they included an aluminum spinner for it, as the one that comes with it is plastic, it woukd just look better. Fortunately the prop and spinner was perfectly in balance so I got no vibration or off sound that you get when a prop is out of balance.
This plane is a very nice flier from takeoff to landing. If your into this type of plane, I strongly suggest it.
