Rabbit stick
GlisGlis:
In my understanding to assign the foil profile you have first to decide if it will be used right or left handed
this will determine if the stick will fly anticlockwise or clockwise.
lets assume we will throw right hand so the rotation will be counterclockwise
the half of the stick more distant from your hand will have the leading edge (thicker part of the airfoil) facing the direction of your distant target while the first half of the stick (closer to our hand) will have the leading edge facing the opposite direction
My guess is that you can use many different foil profiles. even almost elliptical
The ultimate goal is to have the foil profile providing a little lift, balanced enough to maintain the rotation plane horizontal
to fine tuning it i've seen a video where they reduced little by little the profile at tips
My guess is that a pronounced profile at tips that spin really fast can flip the stick
My test had mixed result. I still have to crack the code
Heavier, wider, costant central curve seems easier to tune
@Aaron
very nice sticks !!

Thanks glisglis.
And yes glisglis is correct. The thicker part is the leading edge, just like a plane wing. And the other leg of it is the opposite way, basically just like a bent propeller.
And yep, the airfoil can vary. On the pvc ones I couldn't get the wing profile, so they just have a slight radius on the top and I added twist to them in opposite directions, not much, but just enough to give a little lift.
When I'm working on one I just end up throwing it a bunch, see how it's flying, scrape a little here or there to get the profile a bit different, throw again... over and over until it almost hovers off the ground as it goes.
As for throwing, yep thats how I hold it, but they are thrown horizontal to the ground if you want them to go straight. You can also throw at slight angles from horizontal and get a little bend to the flight, or even an s shaped trajectory, but that's more for fun than it is useful as a hunting tool :)
Here's my rough diagram. I hold this one where the arrow is, rotation direction shown, and the lines are the thick parts of the airfoil.
Hope this helps, they are quite rewarding when you get them to fly correctly.

Got it! thanks a bunch.
bjrogg:
I’m really interested in this. I’m definitely going to make one. Probably several
This just really fits me well. I pilot in me loves it and so does the primitive and wood working side.
