Composite-ARF Impact question

[Mark Hunt]

I'm gonna say it.....just can't hold back.....if an Aires fuse was like this 
we'd be hearing all about how hard it is to find a quality pattern kit in 
the US.  Drives me nuts that so many people have been fixing this without so 
much as one bad word about this company.....


there...I feel better.
