I hope my english is not to bad, because I speak only some words of your language.
Lee, is it possible to get a 1:1 picture of the used jig and a picture/video of the cutting procedure/setup for the Assassin?
I started cutting EPP some month ago. My first attempt was something like your pinata. The airfoil was a modified Clark-Y with 18% thickness (round 50 mm) and 285 mm lenght. It flys great.
But now I saw your fin-less Assassin and I would like to build something like this. It seems so easy to start and catch this plane and it looks so cool
