  1. Unfortunately I don’t have much of a choice with my timeline and I don’t really want to leave it out here in Clovis, NM. At this point I’m used to constantly switching mechanics, just hoping someone had experience with a shop in the area.
  2. Hey guys, I am moving to the Pensacola, Fl area at the end of this month and am wondering if anyone has some info on a good mx shop in the area, my annual is coming due soon. Thanks in advance for the help! -Jeremy
  3. Looks like this new ka-310 with the ki-300 might be a decent replacement option if the ki-256 starts to go. https://www.bendixking.com/en/~/media/bendixking/files/n61-2019-000-000_aeroflight_electronic_attitude_indicator_autopilot_adapter-bro.pdf
  4. I see about the same. FF numbers slightly lower than book numbers for given power settings/tit limits, somewhere between .5 to 1 gph less. I also get about 5-8 knots less than the book numbers. Typically fly the 72% power settings. For climb I usually power back to the 88% power setting and around 110 kias not climbing above about 12k feet I see about 1000-1200 fpm in the climb. CHTs 380 or less at cruise depending on where cowl flaps are at and how far ROP. My ff full rich at TO power is set a gallon or two higher than the book numbers but full rich in the climb does keep things very cool.
  5. To clarify, I was running the 55% ROP numbers from the rocket chart and leaning to LOP so like you said, more like 51% actual power. That seems to give me somewhere around 155 KTAS maybe a little bit faster but in that ballpark. 19 gal/hr is on the rocket chart for 72% power as the min fuel flow. I’m guessing that on a much hotter day at a higher altitude I would probably have to increase fuel flow to get those tit numbers but I haven’t tried that out yet. I have run the tit check from the rocket manual and have two tit sources so I’m fairly certain the numbers are good. My biggest question is would the tit decrease with gamis. Right now I have about a 60-80 degree split between the egt on my hottest and coolest cylinder according to my jpi. In my mind it would seem a smaller split between egts I would potentially average out to a lower tit for any given power setting and fix the high tit. I would love to buy some gamis but if I’m going to continue bumping up against tit limits then I’m not sure it’s worth the cost.
  6. Just a couple days ago I decided to try the 72% power setting on my way back from Dallas and found that at 19 gal/hr kept my tit at about 1560-1570 after adjusting for temp correction. I’ve also tried some LOP at 55% power. If anyone has gamis, I’m curious to compare. At lower alt (8500 ft) I have gotten it to run smoothly at about 11.5 gal/hr and approx 155 Ktas. The biggest problem I’ve seen though is tit is right up against limits and at higher altitudes tit starts creeping up to a point where I can’t run LOP at all. I am considering buying gamis but was hoping for some real world experience and tit numbers to find out if it’s worth the cost. I’m sure most of you guys are already tracking but one of the biggest frustrations I had early on was hot starting. I read the Mike Busch article (https://www.avweb.com/news/airman/184350-1.html) prior to buying the airplane so I was expecting it but what seems to work the best for me is a combination of the articles recommendation and the rocket manual. I use mixture cutoff and full throttle with 30 seconds of primer. Push the mixture back in and give it about 3 seconds of primer. Then pull throttle to a little above idle and mixture to cutoff. I start cranking the engine while smoothly feeding in mixture until it fires. Not sure that’s the best technique out there but it has worked for me every time.
  7. Just ordered one of these things, hopefully it works well. Clovis, NM is miserable in the summer.
  8. The 1690-1700 is peak for that power setting which equates to 78% power and is only allowed for 1 min to verify gauge accuracy as leaning above 75% for any other reason is prohibited. For 75% power or less the attached chart offers a little better explanation. At 55% power peak TIT leaned 25-50 ROP should be less than the continuous TIT of 1600 but if not it needs to be richened further as well as the variations gathered from the gauge accuracy check above also need to be figured in. The manual explains it a little weird and confusing. Not to get too far off topic though... Like others have said, sounds like his power setting may have been too high, 125 degrees ROP may not be enough based on power setting and could have been well above the maximum TIT. Jeremy
  9. Hey guys, I recently bought this M20K Rocket a few months ago and just signed up here at Mooneyspace yesterday. I'm new to Mooney ownership as well, any tips/things to watch out for? I just dropped it off for annual last week so hopefully get flying again here soon. -Jeremy
