I have for sale the last of my two Apache Blackhawk push/pull spinners. This has been used in a discs of tron project and has had the original micro switches changed for leaf switches. You can easily swap them if leaf switches are not for you. The controller is USB so nice and easy to install & comes with a metalic blue spinner & small screwdriver to take it on and off. As you might be able to see in the pictures, the fixing holes have been widened slightly.
These are no longer available as I'm sure you're aware - I'm open to offers before I stick it on ebay. PM if interested!
