I have/built the Graduator, Viper III, LOC IV, Aura, and have other kits ready to build. Directions are sparse but good enough for an experienced builder. I always add 1010 rail buttons, sometimes also use the 1/4" lug. Also always add positive motor retention, sometimes scratch built Kaplow clips, other times commercially available styles. I don't use the molded nose cone shock cord attachment point, I use an epoxied screw eye/eye bolt in the bottom center hole instead. For me, paint is always optional. Also always use epoxy for construction. Overall good solid medium to high power kits. They fly well and stand up to multiple launches almost as well as fiberglass kits.
