Here's an idea I've had knocking around in the back of my head for a while. Pretty typical glider only I added the pivoting fins designed to add flash and noise. The flash worked out just fine but the glider just didn't generate enough quick left-to-right movement to get the fins to make enough noise. I took this idea and made a crank bait that has proven itself to be a worthy bait.
This glider has been chomped on a couple times so I guess it's not a total failure.
