Dear fellow aviators & builders,
As promised I said I would let you know what I found in the search for a
suitable fire suppressant system.

Several companies I have e-mailed have not yet replied. Must be that word
"kitplane" that scares them off.

However I have discovered a few new very promising systems using new
technology called Condensed Aerosol Generators. Looks like they should be
ideal in a small aircraft. These are new generation replacement for Halon
which as we all know is rather toxic to the environment. The first is a
product called Aero-K.

Promoted for the computer room, it can also be used on any class A, B, or C
fire. It can be electrically controlled, which means a possibility to wire
it up to a fire alarm. Things I like are, small, compact, non pressurised
until activated, non toxic, can be used on electrical fires etc, etc,
I have emailed the company for more info. Meanwhile have a look yourself.

The second product is virtually identical, called Pyrogen.

"Automotive" and you will see a real life situation on a Norwegian bus where
a fire was extinguished. Any system you choose should be rated for class A B
and C fires.
Caution. If you are thinking of using a foam system, remember foam cannot be
used on an electrical fire, or where there are bare electrical terminals. It
is water based and can make the situation worse.
Safe and Happy Flying.
