New Plan -- Spear Tip
Another "Schoolyard Sounder"...
Uses 13mm A3-4T. Over 450' altitude. Less than 5 FPS deployment V...
Although the fin is shown in the RKT file as having a split (limitation of the program, grrrrr...) the actual fin shape has no split. You might find it necessary to construct the fin in multiple pieces to align the grain for better strength and dimensional stability.
See the attached fin patterns...
Enjoy!
