I put 3 stripes on the bottom of each wing on the one I had. I ran a Saito .72 four stroke on it which weighs about 16 1/2 ounces. The 1100mah reciever battery went in the fuse near the tail to balance it with no additional weight. I can't comment on your engine choices since I have no experience with any of them. You will enjoy the plane it flies very well.
