The HP .61 F R/C Gold Cup comes with this new muffler design. Before RJL bought HP in the early 1990 all mufflers were of a strap on design.

The first thing RJL did with the new production was to make the muffler bolt on with two 4mm Allen screws.

Now MECOA, which is RJL's new name, made new dies and slightly different muffler than the original style.Still have that great looking black anodized finish and mounts with the same two Allen Screws.
