This past summer I decided to get a "beater" kite to use when introducing new flyers to the fun. I wanted something relatively inexpensive and tough with parts readily available, but yet flew well and predictably in a pretty good range of wind. I've flown a Widow NG before and really liked it, I think it's a tremendous kite for the money. It was more than I wanted to put into this project though, I wanted to keep it around $120 or less if possible. I had high expectations for the KHK Skyscraper since it seems like a simple rebranding of the Widow NG. I flew one that Kitty Hawk Kites had as demo model and was a bit disappointed. Now I don't know if the bridle settings were as stock or if someone had tweaked them, but I didn't particularly like how it felt. It felt sluggish and mushy and seemed to flex way more than I liked. I also wasn't sure how much of a beating it could take before a break. Not too big of a deal, but I wanted something that felt a bit more durable. I love my Widowmaker Pros and really liked the Widow NGs I've had a chance to fly and I recommend them often, but didn't feel good about the KHK Skyscraper, which surprised me. And don't really know why.
Just was my unqualified opinion, other opinions may vary.
