S, From my perspective, the GPS 175 seems to integrate fine with HDX. I load the flight plan on the 175 and it flows directly to HDX. The 175 shows on the HSI independent of other navigation inputs. Garmin's MO prevents HDX talking to the 175, much like Foreflight won't talk to the 175 but Foreflight it will talk to HDX. You can have two flight plans - one on HDX and one on the 175 but I can't think of a situation where this would be necessary. I can't speak to the legalities of the HDX/175 paring. I'll look at the documentation when I get home to see if I can comment factually. I had an avionics shop do the install and I seem to recall FSDO did inspect but I'm not 100% sure. I have not flown behind Garmin G3x but HDX is very cool. For $$ reasons I have not installed the IMS yet but it's on the list.

I've been flying with HDX for about a year and have found the system to be all as advertise. None of the components have failed so can't speak to their warranty support. They answer the phone when I call and respond to emails fairly promptly. The delay in the AP is a bummer for sure but I'm hanging in there. I think the reality is the AP will not be available until late 2022, despite what their website says.

They do look cool. Is there a performance benefit?

I would guess an hour. Should be plug-n-play. If you need one I have the one removed from a 1979 K. Working when removed.

+1 for Niagara Airparts. Super helpful and fast turn. A new/rebuilt starter is a good idea. I got the energizer and now have much better cranking and it seems like less drain on the battery (my hot starts require more cranking time). There is a lot to remove to get at the adapter and while it's out you should consider getting the alternator rebuilt. It's easier to get at when the adapter is out. I know...it's money but will probably save some bucks in the long run.

That is really bad news. I installed HDX last year (I think HDX is great) with the expectation that the AP would be available early 2021 (it was previously published as late 2020 but I knew that was unrealistic), now it looks like 2022, the way things are going. Should have kept the very basic Century II when I did the up-grade or gone Garmin...one more year of hand flying to look forward to. The model change is not a total surprise, I think they are using a J for the test bed, which is different than the early and late airframes. I'm glad my K fits into the current approval window. What a bummer...

I've had HDX for about 5 months and so far so good. There are several shops that install Dynon - Baker is often on this site - talk to him. I had the install done at Advanced Aero in Reno, NV and I'm happy with their work. There are probably lots of shops that now install Dynon in certified aircraft. I'm using the Garmin GPS 175 as the WAAS navigator and it interfaces nicely with HDX and not terribly expensive. I kept my old nav/com and com, which work fine and also integrate with HDX. The biggest drawback to HDX is no certified autopilot for Mooney at this time. I hope that changes in the next 4-5 months. I could not get the 10" and 7" screen to fit without a lot of panel modifications to the breaker panel. It might be something I do when I have more time (retire) but I don't mind the analog monitoring gages but definitely not as cool as some other panels and my engine monitoring capabilities suck - I still have the "classic" scanner ( I can hear the laughter). I'm happy with HDX but not happy about no AP. Go for it!

Sent you the email, Greg. I'm glad you're taking this on as Dynon is going to miss out on a lot of business as Mooney owners will be forced to go Garmin for their up-grades if the don't see significant progress coming from Dynon. HDX is fantastic (anyone can PM me for a discussion) but without an AP it's not a complete system. There's a lot more button pushing with modern avionics and that's ok if someone else is flying the plane but I find that hand-flying, and button pushing, in IFR conditions, with ATC giving redirect instructions to be something less than a thrill. We need the AP, Greg.

NEW PRICE! If someone needs this, let me know. $10.00 and still free shipping. All our panel upgrades make this obsolete but perhaps someone can use it.

Gasp, I just looked it up, I've owned my 262 for 20 years. Upgraded from an E. It's been a great plane in so many ways and I hope I can fly it 20 more. Congratulations, you're going to enjoy all the capabilities of the 262 mods and ease of operation of the MB engine (no offense to the 231 guys intended).

I need one ...Hope someone has at least 5.

$75.00, free shipping! Removed for panel up-grade. Money back guarantee it works. Happy new year.

You are correct, keeping them full adds far too much weight. I only fill them for long flights otherwise I keep about 5 gallons in each. In the 15 years I have owned the plane, the tanks have never leaked - keeping some fuel in them must help.

Model: 231 Engine: TSIO360MB This is really a tale about progressive starting problems. It started with hot starts and progressed to just plain starting. Here are the attempted solutions and the outcome: 1. Installed new/rebuilt starter - much faster crank but still very difficult starting 2. Installed fine wire plugs - made cold starts easier but did not help with hot starts 3. New mags (not rebuilt) - big improvement in both cold starts and hot starts. I will just buy new ones rather than OH from now on. I know it costs more but an engine that won't start is sooooo frustrating. 4. Installed SlickSTART - this seems to have made a huge difference in starting. Cold start is now 1-2 blades but the BIG improvement is hot starts. The procedure in the POH never worked for me but it does now. I now have confidence that a quick trip for cheap fuel will not leave me cranking and cranking and hoping the battery will last. I know the impulse coupling is supposed to give a boosted spark but it might not be enough in all conditions and this little box perhaps does the trick. Worked for me.

I'm the lucky owner of a 262. The POH is for a 252 (although I have the 231 POH also). I recently developed a new checklist because the panel is now glass so a lot of the checks change. I also emphasize/repeat some of the things I tend to forget, which are now in bold red font. I'll private message you what I developed but it may need a lot of editing to meet your configuration.

John, I have tried to do it without taking the spinner off but 75% of the time it did not work well. Now I just take the 10 minutes of time to take the spinner off. Peter's approach is close to mine - I have a large box and a big piece of foam I put under the cowl and then lower it down - kinda hinging it from the back. The reverse works well to get it back on. Patience seems to be the trick for me. I can do the whole cowl in a little about 30 minutes now.

Really frustrating and the Mooney certification estimate keeps getting pushed to the right. I love my HDX but sans autopilot makes only half a system...

MS is great! You guys have provided some good ideas. In my situation, Coy Jacobs took the rotating beacon off about 20 years ago to gain 0.3 kts of speed and I don't want to put it back on at this point. The turn coordinator did help remind me about the master switch, especially when the bearings were going bad, but it's gone now with the new glass panel. Leaving the strobes on is a great idea, I'm gonna try it.

I did a simple on-field relocation last week and left the master switch on for a few hours. I was in a hurry. This resulted in the battery being too weak to start. Embarrassing and a pain in the butt. Have any of you installed a device to remind you that the master is on? Buzzer based master being on and no oil pressure? LED in prominent location when the master is on? I realize getting field approval might be difficult (impossible) but I'm interested to know if there is a solution - other than religious use of the shut-down check list. August

I had the same issue and a rebuilt starter made a big issue. Mine was about 15 years old. New battery and cleaning all the cable connections did not help. Rebuilt starter is not terribly expensive.

Thanks, 231BN, there are several fuse holders on the copilot side, I'll start there. The schematic is also great but takes young eyes and patience to trace, but I'll try. Back to the hangar this weekend. I'll keep you-all posted as to what I find. August

Hobbs meter not working. Airplane = M20K 25-0308. Would appreciate advice on trouble shooting. Specific questions: 1. What drives the meter - oil pressure switch? 2. If I put 12V to the meter, should it run? 3. Is there a fuse or CB in the circuit? 4. What am I not asking that I should be asking? Thanks

The servos were not installed but all the wiring was installed while the interior was out and the wing panels were open. Should make the final install more efficient.

The Dynon website now shows Mooney certification in the first half of 2021 and the progress bar has not moved much, if any. I'm enjoying the heck out of HDX but not having an autopilot is a real bummer. This is really disappointing news. Picture of the panel in the climb out of HWD...notice the blanking plate where the AP head should go...UHHHH.

SOLD to Mr. Ross Taylor. I had an E before the K and loved the heck out of it. Flew it everywhere!
