@FloatingFlint Whoa!! I just saw this. Those are beautiful! I like the colors.
What wood are they?
I left a comment on the video. I'm also hoping to see your results on whose stick goes farther.
If you are having the stick go too far to the right, try bending the stick downward (tips toward the flat side), i.e. adding anhedral. I'm pretty sure that this helps combat the tendency to turn to the right as gyroscopic precession kicks in. Adding anhedral also seems to decrease lift, so you might have to twist the wingtips to add some angle of attack to balance it out.
In other news. Here is a video of me throwing my best 3 sticks, all coastal live oak (native to CA). The first two are about 360g and the last is the one that I made in the first video in this post (tuned up a bit) and it is 320g.
My best stick I've gotten to 150m and my second best, about 135m.
