I'm a little bit skeptical of the 170 KTAS C model and here's why. Assuming a standard atmosphere, at 6500 ft, 170 KTAS would be 154 KIAS. According to Sequoia Benchmark, with WOT (MP=24.4") and 2400 rpm, to achieve 170 KTAS, the drag coefficient in a Mooney with stock Hartzell propeller (87.5% eff.) can at most be 0.015. Such a slick Mooney C does not exist? According to the data in Sequoia, a M20J has a drag coeff measured of about 0.0168. A M20C could hardly be lower, right? From the data in Sequoia, M20J N1220G has a cruise speed at 6500' STP with 24.4" MP and 2400 rpm (70% POH pwr) of 163 kts. To get the J up to 170 kts cruise, rpm must increase to 2630 rpm. Who does that? I'm calling B.S. on the 170 kt C unless they were cruising at much higher than normal rpm.

Flew for a weekend beachy getaway to Destin, FL, (DSL). Early this morning a cold front went through, and on the flight back to TCL this evening we had a 40 kt headwind component. Notice the asymmetrical glide ring! Hate to see it, but that is a pretty nice feature in Foreflight. The trip down was about 1.4h, and 1.9 back.

The economics of gas turbine engines only make sense on larger airframes. A PT6 on anything smaller than a Pilatus is an expensive toy because it won't be very useful except for entertainment (e.g. Draco). While the power density of turbine engines is enormous, so is the fuel flow. Taking advantage of the engine requires enough seats to justify the expense, and enough fuel to allow decent endurance. Four seats and 1000 lb UL ain't enough and never will be, not with an engine that can drink 350 PPH in cruise.

Thanks for including the link, great read! Despite what the article says, I think the real reason for the vertical tail on the M20 series stems from the fact that it would be much easier to make with plywood. The aerodynamic argument that in a stall or spin, the forward swept tail will have a larger windward projected area is undoubtedly true. Yet M20s are not noted for having excellent spin recovery characteristics.

Followed the instructions. Works great on my C. Agrees with the book.

Looking at the post-accident photo of tha poor Chickenhawk resting in the midfield here, it seems that maybe 20 degrees of flaps were set. http://www.kathrynsreport.com/2019/11/cessna-172n-skyhawk-n739ua-incident.html

The lack of speed control was a contributing factor. Can't tell if the flaps were down- I'm guessing not. Dead feet syndrome. Almost seems like he hit the left rudder pedal? I like the final scene where the windshield was full of grass.... Classic.

IF that is all it did, you should just pop a cold one and consider yourself lucky. Buy a lottery ticket.

Some of the KX155 radios in our airplanes have capacitors that leak. Some of the trim pots, volume knobs and solder joints become problematic as well. They are good radios, but need some TLC after all these years. They still sell for nearly $2000 with a glide slope. A thorough test/repair/adjustment with replaced leaky capacitors cost a little less than 1 amu in early 2018.

I guess four or five Naugas had to die for these hides. We plan to put sheepskin covers on the front two after we pay for the next annual.

A local upholstery shop here in Tuscaloosa did the sewing. The fellow that did the work came out of retirement because nobody else in the shop had experience with aircraft seats.

Thanks for the detail. Look forward to hearing more. Not surprised that water rushes in- non-pressurized aircraft leak like a sieve.

Thanks @mark21m20c. We have not yet changed the carpet. What is in there now is not too bad color wise. There are some stains near the rudder pedals from what I assume is sweat from all that horsepower. Quotes from two places kind of scared me off. SCS interiors has really nice products, and I ordered samples. Their prices are on the order of $500 for basic nylon carpet. The airtex prices were less O($300), but their order form didn't seem to match my aircraft. My plane has four pieces of carpet- floor pilot, floor co-pilot, a thin piece attached vertically along the front face of the box beam and the piece on the baggage compartment floor. The AirTex form had several more pieces. So, I'm going to save carpet until after the annual sometime in 2020.

There is a paint job gonna happen in a couple of years. I wonder if there is a way to discover the factory original paint scheme?

Hi everyone- just want to share some photos of the new interior that we finished this past weekend. My co-pilot and I did all the work except for the seat upholstery. The new side windows are great. Solar gray with UV control all around. Not sure when it was last re-done but it was time for an update. The 52 year-old no longer smells like an old DeSoto with straw-filled seats!

Niiiice.

I wouldn't recommend that. Your transponder still transmits a discrete hexadecimal code that you cannot change, and that will reveal your attempt at spoofing. They would figure it out.

"wobbly exhaust valve"? That sounds expensive.

As a two year participant in MS, I have mixed feelings. Here's why: The anonymous nature of the site can lend itself to a lack of civility when things go sideways due to either misunderstanding, misinterpretation, misspelling, or sometimes just a strong difference of opinions. I've learned to try and avoid writing anything that anyone might take the wrong way. Some long time members are very friendly, like @carusoam who I'm sure everyone will agree is immediately welcoming, and I agree should be considered the "Dean of MooneySpace". In my opinion, this site should abandon the anonymous model. It will promote civility. Anonymity brings out the worst in some people. Secondly, this site should include a FAQ where longstanding threads addressing common and widespread issues with our aircraft should be posted. Using google to search site:mooneyspace.com frequently turns up a discussion of almost any issue I have. A thread with hundreds of posts, on a common problem, that is discussed to the point of the equivalent of a peer-review journal paper, should be easy to find. Sites usually do that by establishing a FAQ section. That will require one or more active moderators. Finally, I have learned a tremendous amount. A good search using google will often show that someone else has been down whatever road I find myself on. If the answer is not there, or if technological change is the issue, then a well-worded question will often elicit great advice. The professional folks who participate on MS are often very helpful with regards to mechanical and/or maintenance and/or insurance advice. @Clarence , @Cody Stallings @M20Doc and @Parker_Woodruff immediately come to mind. They really help our community and I suspect that many of us have gained from interactions with them and other professionals that choose to answer our questions. My 2-cents worth.

Here in Alabama I frequently hear the call sign "MafiaXX". I'd like to hear the story behind that one.

@EricJ nice thread and I enjoyed your pdf article. Do you think a SDR setup could be used to do the spectrum analysis as you did, or would it be too noisy? It seems that if the antenna is as far way from the computer as possible and near the USB adapter it might work? Thx.

When we recently redid our interior, the upholstery place made us some, but they were not suitable. So, in a pinch, we took one of my wife's leather belts and a hole punch and made our own.
