Learned something new today! The "3 dB point," also known as the "half-power point" or "cutoff frequency," is a term used in electronics and signal processing to describe a frequency at which the power of a signal has dropped to half its maximum value. This corresponds to a -3 decibel (dB) reduction in power, which is why it's called the 3 dB point. https://en.wikipedia.org/wiki/Cutoff_frequency

Yep, asked Matt to replace the blue capacitor for the same reasons you have. He was curious about retaining the RF filter (gray box) where the alternator output connects to (far right) in the picture. Tempted to replace that too while we are in here.

Contact Lasar - I ordered through them a couple of years ago. @Marc_B has the right IPC part info for the "Shroud Assembly". Lasar can get you the right part number based on your serial number and they may have one in stock or can get you one from Mooney. Their online parts database isn't always up to date.

Time for an update. The aircraft has been at the shop for about 2 weeks and there has been quite a bit of progress both on and off the aircraft. It took a bit to untangle the mess left behind by the previous shop but that's now finally done. GMU-44 has been installed and grounds pulled in (previously there were several by the wing tip). They are going through the stock harness now to see what's needed and what's not. In parallel, we have been working on panel iterations, and of course, scope creek on avionics @donkaye I talked to the shop and managed to get a good deal on a 750Xi so the the nav/comm stack will be completely Xi series GTNs paired with the G500TXi and the GI-275s. Did have one question for folks that did a full panel transformation. Did you end up retaining the RF filter in the circuit breaker panel? Or replace with something new? Or just get rid of it? Picture time... This is what the panel looked like when I flew it in on ferry permit: The rat's nest (harness built by previous shop that was just $..T) and it's undo-ing: Panel area now:

Sign up for MooneyMax (https://www.mooneymax.com) and you may get a factory tour (it was planned at least!)

+1 to chatting with avionics shop if the fuse wasn't the culprit. Did you switch out the dimmer? It is possible they connected the overhead cabin lights to the dimmer switch. Throwing this out as it was suggested for my install - which I vetoed.

The CAD drawing takes into account the sizing of the switches, at least based on specs. EA Panels is great to work with on that regard, we will iterate as needed. P.S. although they are bigger than the stock rocker switches, there should be enough room in the panel for them.

Got the test samples today…these are the actuators only. High boost will have a locking actuator, not ordered yet.

And after they are done with those, spray corrosion X for full service.

+1 looking forward the schedule. Factory tour will be a plus!

Nice. Which shop is this? Will have to add this to the wish list.

I will also add that @Gee Bee Aeroproducts's baffle is of the right thickness and his pre-cut ones makes it easy to achieve the right curve on the top that allows the seal to fold down when installing the cowling but also fold up and seal the engine area with air pushing on it. I did all the work myself with help and supervision from A&P. Fun weekend project. It went from this (click to expand): to:

Heh, couldn’t agree more. I am actually planning on getting a few sets of the customized actuators. Then generic blanks as well. I am working with the shop to have a custom switch body with two different LEDs. The independent lamp on top would be warm or cool white or amber based on daylight visibility. The bottom oval lens will be green. Which reminds me, if others are interested in these switch bodies, let me know. They can do a group order.

Thanks, yeah, I definitely like the cost and availability aspects of the Carling switches.

This is good reference Skip Thanks.

You are not being a Debbie Downer. I actually started the search for replacements chatting with my MSC & IA who confirmed and also asked me to chat with the Maxwells for acquiring them and they confirmed the same. Based on their feedback, all you need is a logbook entry. Maxwell's have been installing these for a while now for the panel work they have been doing. Most importantly, Mooney actually uses the same switches in the M20U, see attached panel IPC. Mooney Acclaim Ultra M20U Panel IPC.pdf

@N201MKTurbo btw, I still have all my panels, I am just reinforcing them with fiberglass and applying a new coat of paint. I am hoping I don't need new plastic.

The ideas here got me searching and I ran across this: https://vantageassoc.com/finishing-materials-window-beading-krbbeige-145.html Seems like the same type of product, potentially a bit wider.

@Falcon Man thanks, let me check with him.

I have a Flight Stream 510 so removal of the card is not an issue. I will look into Pacific Coast based on Don's feedback regardless since all the other pieces are no XI. But agree with getting rid of the old rockers. I like the customizability of the Carling Contura V switches - should be a nice change.

Aha - they don't advertise it on their site like Sarasota does. I will reach out to them, its a short hop away for me :-)

Thanks ZW. My initial take is that the 275 display is denser with information compared to the G500TXi's side panel. So I can glean more in one glance, similar to my current JPI. But time will tell.

Hi @donkaye, so far I have been told the 650Xi version will support Smart Glide functionality despite the 750 being the non-Xi version. Having said that, I don't know of a shop on the west coast that offers the trade-in feature. The Xi versions are definitely worth the money with the faster CPUs and better graphics. If you know of a place that doe do trade-ins on the west coast, please let me know. Not sure if they are willing to ship it to another dealer or whether I have to fly the plane down there.

After an absolutely frustrating attempt to upgrade a few instruments at Cannon Avionics at KAWO for the past year, I am ready to start fresh. The initial work included installing three Garmin GI-275s, a used GTN 650xi, and replacing the GMA347 with a GMA35c. However, Cannon's poor quality of work and leaving my airplane in disrepair led me to see the silver lining: a complete upgrade of all the avionics! I flew my airplane this past weekend to KPAE and love the experience with Regal Air so far. Some may know them as Crown Aviation. This is how a professional shop is supposed to be run. I will use this thread to post updates on the work as well as ... pictures of course! Here's what my panel originally looked like: Here's the proposed new panel: After a lot of deliberation and the already paid-for GI275s, I decided to go with G500TXi with the GI-275 as its standby. I will have the EIS functionality be provided by an additional GI-275 instead of being integrated with the G500 TXi. The GTN750 will remain but will be coupled with the GMA35c. A new-to-me GTN 650xi will replace the KX-165 and GFC-500 will swap out the KFC-150 system. A new customized panel will be built by EA Panels. And the good old rocker switches will be swapped out with Carling ones from the M20U based on recommendations from the Maxwell folks. Taking the opportunity to redo the interior panels and seats etc. Can't wait

I am referring to the gray curved plastic, not the panel. It's not ABS.
