Somebody wondered what was going to keep my fiberglass/epoxy plenums from melting. I guess the answer is "the same thing that keeps your cowling from melting". I talked to Larry French tonight (Lionheart designer) and he said you could put the glass right up next to the fins and it would still be alright. Since Jabiru and others are getting away with it, I figure I can too. It's just like the other KR composites, no real load when hot.
By the way, they weigh 10 ounces each (well, I've only finished one, since I'm on an attic cleaning binge here lately...) Mark Langford, Huntsville, AL N56ML "at" hiwaay.net see KR2S project at http://home.hiwaay.net/~langford
