I finished and flew this airplane a few weeks ago and I must say it is one of the best built airplanes I have seen at any price. True there are some things which can be improved, the paint on the plastic parts being one, but other than that the overall construction is of very high quality. Mine came with a one piece molded cowl so I am not sure if they have changed the cowl design but it certainly looks great with no visible seams. The only improvement on the cowl would be exhaust louvers. But it sure is light and tough, not the heavy fiberglass most of us are used to.
The fuselage is made from laser cut parts and seem to use excellent materials and the fit is great, so is the gluing. I have not seen a comparable design so far. After countless flights it seems sturdy and tough. The wing is somewhat like the old EZ airplanes used to be, solid foam covered with a fuelproofing surface layer and decals. It is a little heavier than the typical balsa and monokote wings but it flies better for the same reason full scale airplanes are no longer covered with fabrics. And it came already joined at the center ready to fly.
My Sukhoi weighs a tad over 8lbs with a YS 91 and it pulls this airplane almost unlimited vertically. And sure it slows down considerably, but like all aerobatic airplanes, you shouldnt be flying it like a cessna, you need to keep the power on up even during landings or you will stall the wing. The airplane flies great and does every manuever in the book and then some. Great job!
