Here it is John . I called it the Crazy Bee and it is just an small 13mm design that I put
together with some scrap parts. I had to rework the file quite a bit because Rocksim is still
quite inaccurate when it calculates drag for both Tube fins and Ring fins. I am glad that the
test flight went well for you and Conner. We'll turn Conner into an Mad Rocket Scientist/Designer yet .

This design does have some custom parts to it unfortunately. I designed it before I began to design rockets from off the shelf parts . You will have to cut the (2) 1/2 inch long rings fins from the ST-1620.

PS. John, I will try to work on an upscale soon, JP.
