The International Cessna 170 Association

Thanks all for the info. I found the attached ad on google that indicates this system may have been available as early as 1954. It also shows the instrument that I think I'm looking for. The wing transducer on the right wing looks very similar to the standard stall warning indicator on the left wing...

Hi, 4489B has a lift indicator on both the left and right wings. The installation on the right wing does not look nearly as clean as the left wing installation (the standard stall warning switch), so we assumed that some day during our restoration we would have to figure out how to remove this piece...

Hi Dan,

Yea, my dad still has the 140. We hope to get it "finished" before we dive too far into the 170, so it may be a couple years before the 170 makes it out to Oshkosh. She'll be there some day though.

Hi Dick, I pulled up an old picture of your panel on the forums. I'm thinking your '54 was red. The maroon/red plastic overlay behind all of the knobs and switches looks original to me (does it have the little diamonds painted on it? it was hard to tell in the blurry picture I found) and has me conv...

I did a bit more searching through my stack of paperwork on 4489B and the google last night. There are articles from Flying 1948 and Flying 1959 that provide some of the story. Metzler came up with the idea in the 1930s and by 1948 had installed this successfully on an Aeronca. It looks like he pate...

Thanks everybody! The maroon trim with blue and grey interior was a standard available combination per the parts manual, and is original on 4489B based on the trim data tag. The paint was redone by the previous owner, but we were told it is a decent match to the original. In '55 Cessna expanded thei...

Hi, In my previous post I mentioned that 4489B was a Wings with Springs airplane. I had never heard of this before and figured I'd share, see the attached brochure. Earl Metzler of Pennsylvania created an STC to replace struts of various aircraft with hydraulic cylinders, primarily to make flight th...

Hi all, First post from a longtime reader, but relatively new member. Last spring, my dad and I bought Bettie, 4489B. My dad has owned several 140s and a 170 in the past and through him, I've become a bit of a Cessna originality fanatic. I've spent more than a few evenings looking through the forums...
