AlexLev Posted January 27, 2017 Report Posted January 27, 2017 (edited) Bought from a fellow MSpacer (through a broker though since he was out of country) who unselfishly sold her because he didn't want her to sit for two years while he was out on service. Since purchasing in December, I've put about 20 hours on it. Huge thanks to various MSCers who have reached out to offer their help and support, notably DXB and a few others who I've been exchanging messages with for the past year. Meet my name plane, lovingly named Pistachio, a '68 M20G. Here she is on the day I brought her home. (Yes she's in a hangar) She's been a blast to fly. I've certainly experienced some issues in the first twenty hours -- my 430W knob stopped working so I had to send it into Garmin for their ~$900 flat fee repair. The donuts on her are original from 1968. Despite having 4,000+ hours, somehow they are still to spec and pass annual. I know this is a larger expense I'll probably have to cough up relatively soon, but it's pretty cool that the donuts are still original on this bird! I also am not sure sometimes of what is "normal" and what is not, since I'm not used to Mooney's. For instance, there's a small little vibration in cruise flight sometimes and I'm not sure if it's just the way the plane cruises or if it's another issue. Despite these things, I love her and want to take good care of her and work anything out. I'm grateful to the previous owner for taking loving care and hope to learn, grow and have wonderful adventures with her as well! Thanks to the MS community for all your knowledge! I hope to continue to learn and contribute over time. Edited January 27, 2017 by AlexLev 11 Quote
ArtVandelay Posted January 27, 2017 Report Posted January 27, 2017 The lighter versions donuts last much longer, on my J they've been changed twice in 36 years, so 18 years, for heavier models, probably less. Quote
Skates97 Posted January 27, 2017 Report Posted January 27, 2017 Congratulations, and I love the name! I'm still trying to figure out what to name mine... Quote
Mcstealth Posted January 27, 2017 Report Posted January 27, 2017 As for the vibration, I would look at the motor mounts and shims. There are threads on this site that are detailed about having the engine shimmed correctly and I would suspect some of the vibration could be starting from there. Congratulations on Pistacio. She has a great look and thank you for not naming her Kermit. Question. Which upgrade is that in the nose? DF Quote
TheTurtle Posted January 27, 2017 Report Posted January 27, 2017 man if I was you Id get a few more clocks for the yoke Is the PC system removed? I dont see the yoke button. Interior looks nice. Do the wires coming off the 696 not drag across your legs? congrats welcome to the club!! 15 minutes ago, Mcstealth said: Question. Which upgrade is that in the nose? I was wondering that as well. Doesnt look like LASARs. Quote
Hank Posted January 28, 2017 Report Posted January 28, 2017 I'm also curious what's on the yoke. The right one looks like a clock (maybe), but the numbers in the left are spaced out wrong . . . His guppy mouth closure looks a lot like mine. Not sure about it's provenance, but my 201 windshield came from SWTA, with two access panels outside. Quote
AlexLev Posted January 28, 2017 Author Report Posted January 28, 2017 The yoke has oldschool 60 second analog timers; great for timing a hold! It is indeed a LASAR cowling mod: http://www.lasar.com/mod-details.asp?id=8 1 Quote

Has a Pathfinder P2A instead. It works poorly, sort of like a wing leveler. I can get it to hold a heading on the heading bug, but turning to a heading is iffy at best.

kerry Posted January 28, 2017 Report Posted January 28, 2017 If you decide to upgrade your autopilot I'd be interested in your pathfinder TC. Quote
Browncbr1 Posted January 28, 2017 Report Posted January 28, 2017 Congratulations,. Let the spending begin! Quote
pirate Posted January 28, 2017 Report Posted January 28, 2017 Good for you! Its great to see another Mooney owner, sure is a beautiful plane you got there. Quote
Danb Posted January 28, 2017 Report Posted January 28, 2017 Alex, lot's of good luck with her, I love you statement "I love her and, and want to take good care of her"' just the kind of Pilots our awesome ships need. I believe they may be having a sale on timers at spruce if you need another. 2 Quote
prflyer Posted January 28, 2017 Report Posted January 28, 2017 Alex, Congratulations on your new bird! I did see it on the Airmods' website and it looks very nice. I'm curious about the performance of the G models. Can you share what real performance you are seeing with the 180 hp engine? Thanks. Fernando Quote

Fernando Certainly. I cruise at 136 knots (no wind) at about 24 squared. Not bad for an O-360 IMHO. 1 Quote
rbridges Posted January 28, 2017 Report Posted January 28, 2017 Congrats on the purchase. I have the Johnson bar and manual flaps, too. Quote
3914N Posted January 28, 2017 Report Posted January 28, 2017 Another 'G owner! I bought mine about 18 months ago and it was my first airplane too. I think you'll love it. Congratulations and welcome! The people here on MS have been immensely helpful as I've asked all those new-owner questions. If you add a location to your profile its easier to provide help. 11 hours ago, AlexLev said: I cruise at 136 knots (no wind) at about 24 squared. Not bad for an O-360 IMHO. TAS? That actually sounds a little slow at 24 squared,even for a 'G. I usually go 8500/9500 ft, 2450 rpm, throttle cracked just enough to make the MP needle move (about 20" at those altitudes), and see roughly 135 ktas on 9 gph. R Quote

R I bet he means IAS - I've been routinely seeing high 140's kts TAS while running hard at 24-squared at 4-6k msl in order to re-break in some reconditioned cylinders on my C. I doubt the G is that much slower. However I have a hard time leaning to less than 10.5 gph though at that setting while keeping CHTs in check. BTW, though tastes differ, I love that particular vintage paint design, pistachio and all . I corresponded with AlexLev some during his purchase and am sure he will be a huge asset to the Mooney community. 1 Quote

Since rebuilding my carb heat box and doghouse, my C will actually run 25° LOP at altitude, but I don't cruise there because I don't have an engine monitor. And it's kind of slow . . . 1 Quote

Per my POH, 24-squared gives %hp in the 75-80% range depending on altitude and actually increases with altitude at a given MP/RPM setting - which that equation does not seem to take into account. I've been running there the last few hours just to break in reworked cylinders, but it certainly does limit how much I can lean while keeping my hottest CHT under 380. I agree it's not an ideal power setting for routine use based on that info. But should I not be leaning at all if I'm really at 80% power? But then FF will be something ridiculous by C model standards (13.5gph). Quote

Hm, well I generally go 24 squared only if I'm down low at 3500 and want to go fast..the IAS is about 145/150 at 24 squared. Otherwise, I cruise at 2450RPM/22" or so.

You can lean at higher power settings but to keep CHTs acceptable you might need to lean to 100 or 125 ROP if you're at ~75% power. With 4 cyl EDM you can be more aggressive. Quote
