He is talking about the starter cone that is on the Kyosho Concept that is screwed to the fan. Wow thats a hard one. The Nexus uses a starter shaft. I would E-mail Kyosho and see what they have. I do know That KSJ made parts for the Concept. You may want to see if you can buy an entire spare airframe Here or on E-Bay. Someone else may know of some parts place that still have Concept Parts. It has been out of production for some time now. It was a good-un while it lasted. Speak up guys here is your chance to move a Concept.

Sorry I couldn't help further,
