Paul good looking decoy's. Your weazel Ball looks kinda familiar to me
I'm glad you can put it to good use.
A couple things you might try to get some better action out of the weazel, is to adjust the contact bar a bit lower so that it just barely hits the tail as it passes by, this will help in allowing the decoy spin easier & allow the tail to swing in a higher arc giving off a better presentation.
Another thing I found was that the little plastic thing a majig that goes through the nose of the weazel & attaches to the motor, is real weak & flimsy & allows the weazel to fold over & not force it to spin in a high wide arc.
So I took some Bailing wire (Tie Wire) about 10 or 12" long, bent it in half, making a double piece of wire 5-6" long, I pushed the bent over end down inside the weazel body & the other end I poked through the hole in the motor body & bent over the ends of the wire at a 90* angle one going each direction, this holds the wire in place. I did leave the plastic thing a majiggy's in place JIC so my weazel didn't go a flying when I turned it on.
This seemed to stiffen it up & helped the decoy swing in a nice high arc, giving off more presentation, IMO the more it can be seen the more it can attract.
Another thing you'll find out after a few uses, (especially in your location) battery life is pretty short, I would get 2-3 hunts out of a battery but the temps here rarely get colder than 20*
Best of luck, Lee
