Were your cylinders new when installed 23 years ago? If so you might consider retaining them. First run (depending on wear) may not be a bad idea if there is a long lead time for new ones If not - Then the question becomes- who's cylinders do you want? I find it interesting that it seems the only "go to" position these days is "buy new" when for decades we field overhauled 4 banger Lycomings (cylinders included) without many issues. All A&Ps had to learn how to do cylinder work in school Its not rocket science, just attention to details. Same with the bottom end. Case goes to say Divco for any work and cert than back to home shop to reassemble with new parts if needed. I guess being an A&P now a days is different than when I went through school Although I did do my own overhaul 14 years ago and its still doing good with 1200 hrs on it since then. Still high 70s on compression and 10-12 hrs / qt of oil.

You MUST pay attention to the proper torque value !! You can't just turn them in !!! Get the proper engine manual and do it correctly. Sorry to be so firm but this is important Same goes for fuel line routing and securing by the AD

If you fly regularly and its not required why? I've got 1,000 hrs on my overhaul using AS W100 or W80 and nary a problem noted. Have never seen even a flake of metal in the filter doing about 100 hrs per year. 10-12 hrs / qt

One only has to look at the parachute club world to see about flying without seats in the airplane Obviously if it was a real problem with the FAA they wouldn't be doing it. Just be able to prove the W&B if asked

IIRC the baggage floor is NOT structural to the airframe. Only has to hold the weight of baggage (120 LBS) Is my recollection correct? Anyone? Anyone? Bueller? :-)

Like I said they told me 14 units (all flat packs) were in stock during OSH

It helps with access and with CG with a 3 blade prop I could easily go out fwd the way it was. Run your CG with 2 in front and no aft weight and see where you are. Then try all4 filled with 100 pounds in the baggage and see where you are.

Or move the battery box to behind the rear wall in the radio access hole where it was put in later years- LIKE I DID! No STC required! All Mooney parts and location so it qualifies as a minor mod (A&P sign off only) The process in contained in AC 43.13 for reference.

I think I have a sheet of MU metal that is supposed to block the magnetism if wrapped around the center post. It would take a full compass swing to verify if it actually worked enough to bring the compass into swing spec.

Tubes (IMO) need to be replaced with each new tire WHY you ask? When you remove the tire and pull the tube out of it look and see what is still in the tire. You will see black rubber "dust" in the tire That comes from the tube rubbing minutely on the tire inside every time the wheel rotates. Think about every landing when you touch down how much the assembly flexes. The tube rubs the inside there every time. Every bump. every brake application that cause the tire to flex the tube rubs the inside of the tire. This thins out the wall thickness of the tube, Also every tube begins to stretch due to the inflation in the tire. They will be larger when deflated than when they were new Combine this with the fact that they are thinner due to the rubbing inside the tire and you get a fold inside the tire when you reinflate the assembly. This leads to more rubbing and a hole in the tube in short order. Not the least of which is the problem of the valve stem (the only part of the tube exposed to weather the entire life of the tube) going bad and cracking causing a leak there (all of my tire failures in 25 years on the Mooney have been at the valve stem). If you do decide to reuse the tube make sure you bend the valve stem before installation to see if you have ANY indication of cracks in the valve stem. I'll bet you will. Granted tubes are about as expansive as the tire BUT its part of the pleasure of owning an airplane. There are limits to the CB club.

Its called the Sharrow Prop It doe a a significant job of lowering the cavitation ( and noise) of a boat prop It has some improved thrust also due to less cavitation But the noise reduction is dramatic

Battle damage might forego the ability to rotate to hover mode so a landing in fwd thrust mode "could" happen hence the ability to "corn broom" the prop blades I can only guess at the landing speed but I would surmise 150 kts would do it due to weight , wing plane form and area. Weight per Sq foot is probably lighter than say a Boeing due to the need to lift vertically so that in it self would lower the landing speed. A Boeing does good at no flaps and about 190 kts over the fence If we look at the V-22 with the engines acting as end plates and compare that to say a MU-2 with the tip tanks doing the same an MU-2 does good at 95 Kts no flap over the fence. Just doing some rough comparison.

The hail comes out of them on the down wind side below the wind blown overhang Its never a good idea to pass a real big boomer under the overhang even if you are 20 miles away. As I said, "30 miles and you MIGHT be going too far out of your way" Experience is the best teacher, I've hit hail in a Boeing and don't want to do it again.

Talked to an FAA guy from DC at OSH and asked him why can't A/Ps be certified under NORSEE He said that is what it was meant for I said I was told by Duncan that they were told the FAA ACO refuses to go NORSEE on A/Ps He gave me his email and wants information to straighten it out YA right! "-(

I just did my 3500 miles around the country VFR using ADSB Wx info only. Never needed to go IFR for the entire trip. Had some BIG t storms to fly around in IA and never felt less than safe. If going IMC I might have a different position though. Felt it was quit adequate for VFR flying. Plotting Wx movements and cell size in flight was easy ADSB Wx works for my flying (VFR) I always used the 10-20-30 rule in big iron. If you're 10 miles away from a big boomer you're probably too close If you are 20 miles away you are about right and Being 30 miles away you might be going too far out of your way. I treat my Mooney flying the same way. 2 notes- NOTHING beats live Wx RADAR onboard if the plane has it (bigger airplanes) Using an app called raindar.com on my phone before departures really helps with trip planning at the last minutes before takeoff.

Yes they are connected across the wing centerline if one engine fails Still has density altitude issues just as any twin engine airplane on one engine (KPGA) As to the landings the propellers are designed to (as they say) "corn broom" when coming in contact with the runway landing in the forward thrust setting. The blades wear down much like a broom at the ends and the entire blade does not come apart upon contact.

Had a V-22 do an emergency landing at KPGA a couple years ago after losing an engine 50 miles east of there, Pilot said he barely made it. Do you know that they can land that thing even if the pods don't rotate to the vertical position for a helicopter landing?

I was told at OSH that the Mooney STC was about done BUT that person had no idea which models it covered, I was also told they had just received the first 14 units (all flat packs) but also didn't know who they were going to

"Never" until, as I noted, we are willing to accept nuclear power or some new kind of 24/7 power source Current technology will not allow us to disconnect from the dino-juice grid ever, and there is no new technology on the horizon that can supply power 24/7 at a moments notice in the amounts needed Going "green" with renewables is a noble idea but when the rest of the world gives you the finger and proceeds down a path to triple dino-juice power plants as they see the folly in "green" for them, it seems somewhat of a strange juxtaposition Didn't Germany just do an about face on nuclear power?

Again common sense isn't so common- Project the above scenario to confined landing spots for numerous "air taxi" drones. Where are they going to land them without tearing up the surrounding terrain? Ain't as easy as first thought

Got a 231 sitting for years at KPGA that ran into a concrete channel while taxiing at night NOTHING is unbent on it yet the owner still pays tiedown every time the airport goes to auction it off. Has been there for 6 or 7 years now. Had a new engine but no insurance

In 2,000 + hrs of flying my M20D I have never had to clean my plugs "every 20 hrs" and I've run massives the entire time. I got almost 800 hrs on the last set of massives. How are you running your engine? What kind of procedures are you using for climb, cruise and decent? Are you leaning aggressively while on the ground?

We will NEVER be able to get rid of dino juice power plants unless we go all nuclear! We will always need a back up standby power source to take up the slack of sudden demands to the grid The wind doesn't always blow at night or on cloudy days Clouds significantly reduce solar panel outputs The rest of the world will rely on dino juice and coal for electricity for the next century as THE primary source of power! Calif shuts off the grid at many times in the summer to prevent fires Where does that leave a one car (Tesla) family? They also tell large areas to not charge there electric cars on certain days as they don;'t have the power available. Wind power per KW is still much more expensive than any thing else even with subsidies. WHY? Can anyone find how many hours a year each and every wind turbine actually produces viable electricity going to the grid? NO! I've tried for 10 years with no numbers yet because they are not published by anyone in the wind turbine industry. Just who is making the money in the wind turbine industry? How many birds are acceptable to be killed by every wind turbine out there? Are we ready to kill every living thing (and keep them dead) under a hundreds of square miles of solar farms that are needed to support a total "Green" energy plan? Going electric with vehicles is only the start of the problems ahead Now back to the title of this thread How to impress your neighbors_? You buy one of these :-) below

There are new props for drones ( hoops or loops or something) that make them go almost silent They are used on outboard motors also and the noise reduction there is remarkable VERY expensive however The downwash still has to equal the weight when hovering no matter drone vs helicopter dosen't it?

And the Aerocruz 100 languishes away with no cert in sight and no communications from BK as to what when or why? Like I was told at OSH "We got 14 flat packs ready to go for Mooney installs" Follow on question was "What models does the cert cover" Answer-- wait for it--- "No idea"
