I thought I would give this one a try. I hear good and bad about them. I have a  Bison Pitts on a 60 size 300s that powers by a OS 61fx that I fly and our sound police at the field doesn't complain about. I see the article and haven't had the time to read it yet in the AMA magazine that might give us some tips. There has to be a way that doesn't cost an arm and a leg so I will keep trying till things work. John
