Sanger Mike,
I have Wayne's system on my 2.5, just the air horn for now. I'm looking at Tony B's or Waynes ECU.
So far I like the air horn. A Stoker is a good hull,I had one, but their not a good as a lake race hull.
I'm not sure how to post photos here but if you go to www.havasubarney.com and make a post I will post them there so you can see.
You Te
