Here ia an 13mm design I call the Star Runner. With an design like this I am hoping that
Rocksim 9 will be able to predict the drag on the tip fins and pods. This will hopefully
allow me to eliminate or reduce the nose wieghts, improve altitude preformmance, and reduce
the Dv's.
Wishful thinking?? For now the A3T-4 is the motor to go with.
3rd Annual
