Sandia Tomahawk Fin Unit BT50 for 18mm motors

My first sounding rocket design! Finally, after a few cold war missile offerings and as well as the first of many upcoming sounding rockets of the 'Hawk' series. This one has a new added feature that includes an engine hook notch at the end of the can so you can use a low profile engine hook. This will be a common standard feature on the Hawk scale series and a regular feature of all my fin can offerings.
