I am going to build a Balsa USA Stingray 40. Given it's design parameters size, aspect ratio, etc., which would more likely be a better flying plane using top speed as a large factor. The full size plane as per plans using a .61 two stroke or a clipped wing version with a .45 two stroke? While it is obvious that this plane was not designed specifically for speed, I thought the wing design and wide usable engine range made it a good candidate for a clipped wing version. Maybe a clipped wing with a smaller engine would be a little stronger and a little"spicier". Thanks, Cliff
