Our Snow Goose Rotary Machine Flyer is designed to work with most existing rotary machines. It has a mesh bottom on the windsock body resulting in less drag on your rotary motor leading to a longer life. Before we come out with these we were replacing motors all of the time and batteries wouldn’t last all day. We have only replaced 2 motors in 2 years of using them with 48 of them running daily. I can’t remember when the last time a battery didn’t last all day. Something made a difference and the only thing that changed was our flyer. It comes with the adapter to attaches to most rotary machine arms.
