Got a '67 7KCAB Citabria and want to add a fire extinguisher in the cockpit. I was looking at halon and similar. What size would you get, looks like 1, 2.5 and 5 lb are what is available. Something else I should consider? Halon worth the extra cost?

Yes, cockpits are one of the places where halon is still the best solution (and legal). Understand that an extinguisher in flight may or may not of any use. If you can't kill it with a one pounder in a Citabria, you better be figuring out where you're going to land IMMEDIATELY.

On the ground, things are a different story. You can get a larger dry chem extinguisher (especially near engine start places and fueling).

'Bout what I figured. Bought a 1.4 lb Amerex Halotron for about $100 off eBay.

What type halon? What kind of fire do you plan on fighting?

I think it is something similar to halon, Halotron, advertised as "clean", rated B,C. I want it for the sort of fire one might experience in flight, electrical, etc. or engine fire on the ground.

Be aware that most ABC dry chemical extinguishers are extremely corrosive to aluminum and apparently other metals. Believe I heard insurance companies typically total aircraft that have been hit with dry chemical extinguishers.

ok, I found my answer, Halotron was designed to replace Halon 1211

When reading extensively about this issue a number of years ago, the conclusion was that Halon and it's derivatives are the only way to go. I don't recall the specific about aluminum, but since a cockpit fire likely means Under Panel, it was said that a dry chem extinguisher will destroy all the instruments that it comes in contact with. So it's very worth the extra cost for the Halon family.
