About this Product
Spinner for the UMX Beast designed to work with the GWS line of props. Now Version 2.1. The side of the spinner that comes in contact with the prop now has holes. So that the exccess material from the shapeways printing process does not get trapped inside the spinner.
This spinner was designed to press-fit onto the GWS line of props (4" to 5" dia.) that are popular with the UM & UMX line of planes. You now have the ability to swap out different size props quickly and easily without having to worry about gluing a foam spinner on straight.
Of course (as with everything) it comes at a price. Weight. Version 2.1 weighs 1.26g. The OEM foam spinner weighs 0.18g. (this is a substantial increase in weight over the Sbach spinner simply because of it's shape.) Please check your "center of gravity" prior to flying.
