Ever wanted to see how to make near-perfect fin fillets? In this week's video tutorial, Erin is going to add the epoxy fillets along the fins to enhance the strength of the fins. They will also reduce the drag along the corner of the fin where it meets the tube, so the rocket will fly higher too. The video starts with securing the rail button down with epoxy clay to prevent the parachute from snagging on the bolt that protrudes through the tube. Then you'll see the steps to creating fillets so smooth, that people will be begging you to tell them your secret. And it is easier than you'd think. See how it is done now!
