Fin creation is a time consuming task because they seem to show style and coolness. But the reality is simple designed fins design are easier to create and get you to the launch site quicker.

Here are four simple fins designs. When using balsa or Basswood, you need to have the grain run along the top of the fin. We normally do through the wall (TTW) fins, so they all need tabs that reach the motor mount.

There is a position relationship between the fins, the fin tabs, the motor mount, the fin slots and the centering rings. They all need to come together in a dry-fit, before the big glue-up. You also need to attach the launch rail button before you try to glue everything together.
