I understand now that he is no longer making them, and that the Central Hobbies Nose-ring was supposed to be a replacement for it. I have had several of the CH nose-rings and they fit so tightly as to form nearly a welded lock of the rubber to the motor. I’m not opposed to making my own nose-rings, but I actually like the idea of being able to purchase something and use it once in a while too. </SPAN></FONT></DIV> <DIV class="MsoNormal"><FONT face="Arial" size="2"><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Has anyone found a P/N or different size O-ring to make these units fit the YS correctly?
