This was a really quick build, the Estes Fin Alignment Guide helped make quick work of the 12 fins. I bought this as an open kit, it was missing the fin sheets, but Semroc to the rescue! The long ST-8 was a little roughed up on one end, but the ST-7 to ST-8 centering ring for the 3rd stage engine tube is almost an inch long, so it helped take care of the issue. This is one tall an skinny rocket!
The vintage Centuri decals were worse shape than I thought and I screwed them up, so had to make new ones. Thankfully I have a second opened vintage Arrow 300 kit and I was able to scan in the decals. I printed these on Avery clear shipping adhesive backed label paper.
