My aircraft is being built primarily for higher altitude XC so I feel a
Halon system under the cowl is very important. 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.

Hello,
I am just about done riveting my outboard lower wing skin on my QB wing an I
have oil canning in the innermost bay. 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

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.

Paul,
I have used a single offset set with an overall length of 5 1/2" countless times.
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.
