Hey guys I use 406 colloidal for shaping and general fillets and use chopped glass for structure. I used to use a lot of chopped glass for fillets - it works but just adds weight. Then I move to Kevlar tape for fins (8 or 16 strips) and just use 406 fins. Simple and easy and strong - 3 parts to order. That Nike smoke I had survived a beating; it works and saved weight in the ass so I am going to keep that technique for big bad-ass power birds. Richard .. The V2 is whipping my ass; I ended up making another epoxy swabbing stick and it broke this weekend so now I have to wait (again) to make a new stick to apply epoxy...
