This landed on my workbench. Either it's a clone or a Redmax in different colored plastic. It's 52cc and a screaming little SOB. It holds its own against my Husky 550.
Zenoah g5200 clone. If you can find the cylinder markings that will tell what factory it came from. I've a couple versions from 42cc craftsman g450 clone to the 56cc version of a g5200.
