This is an upscaled Big Bertha built from an Animal Motor Works kit. According to AMW's website, a limited run of 101 was produced for National Sport Launch 2018 at the request of Vern Estes; AMW still had some left at Airfest 2019 and I picked one up there. It appears to be out of production now.
I painted the rocket in colors matching the photo in the 1979 Estes catalog and made the graphics on my vinyl cutter. On its first flight, the rocket zippered due to a late motor ejection, requiring the top 2 feet of the lower airframe to be replaced. I replaced that section with a fiberglass tube for its second flight just a few weeks later. I finally got around to repainting the repaired section and redoing the graphic, but have not flown it again since then.
