I have been following threads by Neil_W and Thirstybarbarian and got to playing with some ideas inspired by them. I started out with the idea of something low and slow that would fly on an Estes F15.
In an effort keep weight down and drag high, I used tube fins but wanted them angled to make it look faster than it is. I used a combination of balsa fins to approximate the front and rear of the tube with a short tube in between. I also added a short ring fin around it all but the only way thatI know to include this is to use an inner tube so it will capture the weight but the aerodynamics won't be accounted for.
Here it is for your amusement and comment. The goal is to keep it around 1k feet on the F15.
