RE: OS 46AX Muffler
Given the option, I'd use a Tower muffler as they are cheaper and, from my experience, give more power. I've never had one fall apart either. However, the racing rules require a stock OS 46AX muffler.
Hmmm. i should check the local cycle shops for the SS wire as I've used up my stock from the days when I owned a home-built sailplane.
