Newbie questions on my first rocket (Madcow Mozzie)
1. How do I assure that the fins will be aligned correctly? I have 30 minute epoxy or yellow glue to attached the fins. I can't wrap my head around a guide or template that I could build out of foam core to assure that the fins get aligned correctly. The motor tube will have an Aerotech 29mm motor mount retainer. Probably fly on some Estes D12-3 on an adapter.
2. How snug should the nose cone be? I've sealed the balsa with spray polyurethane , filled the dents with carpenter's putty and primed and sanded in hopes of preventing the balsa from absorbing ambient moisture and swelling in the springtime. I can sand it some more and make it looser. Just don't know how loose a nose cone should be. Right now I have to really push to get the nose cone in.
