Great story and your 170 looks great, good luck with the sale. My dad had a 1950 170 when I was very young and sold it in 1967 for a 1955 180. We loved that 180 they are great in every way the 170 is great. Can you post some pics of your new 180?

You mentioned your fuel burn on the new airplane as 14 to 14.5 GPH. That sounds kind of high, to me, for a normal cruise burn. How does that pencil out on a naut. miles/pound of fuel ? Considering that the specific fuel consumption should be almost the same as the O-300 engine, I would have expected a more economical figure.

If you have the stock O-470, at 23" and 2300 rpm you should be seeing 12gph.

You can lean the 180 just like the 170.

Don't know where the first photo is, but are the rest Comb Ridge, Valley of the Gods, and the Goosenecks of the San Juan?

Yeah that sounds high to me too and i have flown a lot of 180's...which is why I have a 170. Anyway a general rule of thumb for fuel flow is to take the horsepower and drop the zero and divide by two. Should be in the 12 to 12.5 range from the ones I have flown. Your flows sound like you have a 520 Continental in there:)

mine burns 12.0 @ 2350 and 22.5 mp at 6000 range . at 11000 and 2350 rpm fuel burn is in the 11.0 range

The 180, 182, 185, and 206's are all FINE airplanes. I love them each. They are good, fairly low-cost real X-country airplanes that can do the job.

But they do not operate nearly as inexpensively* as a 170, and that is why I decided on a 170 as my final choice for the rest of my ownership days.

* per-mile they are all virtually identical with the 170 as far as gas-costs go, and due to their speed differences they will save a little time, of course. But for pure, per-hour cost-of-operations, and cost of MX-reserves per flying-hour.... the 170 is significantly more economical.

If I were WORKING my airplane....I'd go for a 180/185 or 206 (normally aspirated.) But for general "family car of the air"....it's the 170 for me.

I've been thinking of a 180 as well for float Ops, I would have to sell the 170 and the XP but I have also received advice from far more knowledgeable individuals than me which somewhat mirrors George's comments. Ah...to win the lotto...
