Just reading over the instructions on my new Estes Solar Flare and a couple of things have me confused. Never having had to add nose weight their instructions having me do this early on in the build process but I'm thinking I should complete the build ,add the motors and do a swing test before adding the clay nose weight.Second question is finishing the ring fins.How does one finish the interior of the rings once attached?I'm thinking of getting some auto pinstripe tape to cover the area where the ring attaches and finish them before mounting,is there a better approach? All input will be greatly appreciated
