IQSY Tomahawk Fin Unit BT50 for 18mm motors

Arguably the most reproduced classic scale subject of all time. The IQSY Tomahawk! This one piece fin unit has all the details of the real motor/fin assembly scaled down from drawing information researched by such rocketry luminaries such as preeminent NAR founder G Harry Stine, and from the popular scale data book Rockets of the World by Peter Alway. You will no doubt find this to be a perfect scale/ performance rocket for BT50 tube size, taking advantage of its thinner tube wall thickness. A true high flyer! It has with all my 'hawk series fin units, it is a one piece design, has built in centering rings, and notched engine hook option in the rear of the unit. I recommend additional motor mount support using a slightly longer motor tube to support with additional centering ring, but one can forgo this for more performance. It will work regardless of your construction technique. Beyond this, as usually stated for all my designs, it is the end users responsibility for the overall design, construction, safety and stability of any scratch-built rocket.
