I'm just finishing a BT-50 (24mm) build that I designed with the intension of it going pretty high. I'm going to put a Quest C12-8 motor in it.
It has the smallest fins I've ever put on a rocket this size. Theoretically, they are enough, but I'm wondering about the length of the launch rod I should use.
In 3/16, I have both 3' and a 6' launch rods. There will be friction between the lugs and rod for less distance with the 3', but the rocket will leave the 6' rod at a higher speed, so might fly straighter.
Just wondering what some of you more experienced rocketeers think?
