I am thinking about buying 2 Zinger-Winger II G3's and Dogtra electronics with duck sound. Any helpful suggestions regarding this equipment would be helpful. Does anybody have any experience with using these smaller launchers ( which is why I picked this model). I also see where they now give you a choice of solenoid or servos on the release. Any comment here? I have heard servos have more torque, less prone to contamination from dust/sand, but more like to fail from water damage. I am using these for hunt test training.
