Wow thats awesome!
Have u tested him in the water yet?
What kind of material are the fins made off? Dont u fear that they may break, if they touch one of the billions swedish rocks in the water?
Thanks for the flowers
they are made of beech wood and those are slow sinking glider. I used stainlees screw eyes and painted them all with createx auto air colors. I didnt used any foil for. They are approx 6.5" long and weighs 3oz.
