If you are running a ZP-62 or ZP-80 motor from Zenoah with No Pilot, this 4 Bolt Pilot Washer Assy. will help you get things aligned.
Just bolt it on for a concentric Tru-running spinner and propeller! This adapter has a beefy 10mm Pilot so backplates and hubs require a 10mm hole.
This adapter also features the same popular bolt pattern as a DA-50 gas motors for many 50 size gas motor applications.
