Are you familiar with the Laser 3d, made,in Belgium I believe, and how it compares to the flip; size, performance, weight, and power required?
5.5 lbs for my Pizazz with a YS63 is just to much weight for a small plane and the distributor told me 7+ lbs for a UCD with a 2 stroke 60. Again to much.
5 lbs for a flip sounds real good. I've seen a Lazer 3d fly with an OS50 with an ultra thrust muffler and it looked good and light. I've heard claims of 4 to 4.5 lbs.
