Rubber Band Powered Projectile

Ever since I was a young boy, I was always obsessed with shooting things.  When I saw tc fea’s design for the Rubber Band Powered Flying Thing, I decided I had to try and make one because it looked so cool.  I did make one and it worked extremely well, but I then asked myself if it could somehow be improved at all.  I decided to design my own Rubber Band Powered Flying Thing soon after.  
I decided to try a new design that included four blades instead of three.  I also made the instep a bit higher to add some weight to the product and made the edges more slanted in order to give it the ability to cut through the air easier.  This version of the Rubber Band Powered Flying Thing is a bit smaller than the original and was pretty much a modified version I created in order to test which design worked best.  So far, I have concluded that both designs go pretty much the same distance if you shoot them the same way.  However, the version I made is much harder to shoot because of its size.
