AERODYNAMICS:

if you want to make a rocket or a missile.. and want tO deal with its aerodynamics.. Just use a slender and lng body instead of curvy ones..and put a little weight at the front tip.. Nd then make it pointed.. This weight helps to keep the balance while in air.. And use 3-4 back fins.. On the side walls of the body.. Surely it will be much better than others.. Personal experience..
