Byrano Airsoft got this video that demonstrates an installation of the Polarstar Airsoft Kythera V3 HPA engine... "My install of a Polarstar Kythera into a Cyma CM076A. I am not a tech and before this video I had never opened a gear box before. I’m providing instructions via text but my voiceover will, instead, go over my experience working on this build and what I’ve learned in the process."
