Think how long it would take you to get on the ground from 10,000. I plumbed a 10 lbs bottle to the front side of the cowl. I haven't done the outlets yet but am planning to saturate the whole cowl. 10 lbs is alot and my bottle is controlled by a hand valve so I should be able to handle a full on fire and some residual flame ups. I also have a 10 lbs for the cabin but that might be over doing it. Both mount side by side in between the occupants feet.

It looks to be about 1/4" movement with concave being the predominant state. Is this acceptable? If not what is the remedy? It is the same bay as the access panel so I can get behind the skin. TIA - Pete ________________________________ Message 3 _____________________________________ Time: 09:32:33 AM PST US From: "Cory Emberson" Subject: Re: RV9-List: Fire Extinguisher --> RV9-List message posted by: "Cory Emberson" Norman, I just wanted to put a "me too" in there for the info on the H3R site. Disclosure: I did word processing work for Steve Berg (the founder) about nine years ago, and saw his demo for putting electrical fires out. It was impressive. And I did buy a Halonaire extinguisher from him to contribute to the Tiger's onboard equipment. Haven't had to use it, but it's good to know that the panel won't get wasted by the extinguisher.

Since most of my riveting is done with one hand on the gun and one on the bucking bar, a couple pieces of duck tape around the set and the gun keep the set from rotating. This is with a slow hitting 4X gun. With a fast hitting gun you'd best have a helper so you can use both hands on the gun and rivet set. Bruce Cruikshank n19z@earthlink.net Why Wait?
