    LOP again

    Considering that there is a TIT probe on the right side only, using TIT to set power doesn’t seem really precise to me. I lean my 2 richest cylinders (3&5) 50* LOP. set power big mixture pull enrichen to 18.5 find peak in 3 & 5 take a picture of the engine page with my phone lean to 50 LOP in those 2 cylinders, which is usually about 65* LOP on the TIT gauge. add back an inch or so of MAP if fuel flow is below what I want (16.5 GPH) Mine is a Platinum Edition engine, which supposedly has balanced injectors. It runs quite happily down to 100* LOP or more on the TIT gauge. -dan

    LOP again

    The POH power setting tables are crap IMHO. I suspect they are an artifact of certification standards rather than an indication that Mooney doesn’t understand power settings. The ROP settings are way leaner than what you’ll get, and LOP settings adjusted for OAT are stupid. The Best Economy settings cannot be duplicated in my plane (published FF is near or at peak TIT.). No matter… Mid teens… if I fly 30.5x2500, 100ROP is something like 22.5 GPH. I don’t fly cruise settings ROP. LOP, power is a function of fuel flow. Period. 13.7* FF is approximately the power produced. This table is a dog’s breakfast of various power settings. 18.7 != 17.6 != 16.4 in terms of power. And if you’re flying LOP and fixated on a MP/RPM combination, you’re doing it wrong. I fly 30.5 ish x 2400 @ 16.5 GPH. 16.5*13.7= 226HP, or 73%. Same FF at different RPM/MP combinations are very similar in IAS. I vary MP to achieve desired FF at desired TIT-EGT’s. so… 16-17,000, where I cruise most of the time, that is 203-205 KTAS on the G1000, which is 2ish knots below true-true. My plane has TKS, which probably costs 5-10 knots in cruise. It really is an amazing machine. -dan
  3. Maybe this list could help. https://themooneyflyer.com/cfi.html -dan
  4. Interesting, it looks like he doesn’t offer them that way for Mooney anymore. It’s worth a call to redline. The ones that lock over center work better in my experience. I moved to D42 quite a bit with one.
  5. Works fine with the considerable weight on an Acclaim. I would, however, recommend the version that uses a locking lever arm over the old style “push down” version. Both are available new. I chose the old style because I didn’t want to change my hubcap and wish I’d gone the other way. But it’s not a big deal either way. This is in Florida. Up north, no bueno. Snow, slush, or ice on the nose tire really reduce the roller:tire friction. -dan
  6. FWIW Ijust got 2 for my TSIO550G from Spruce, easy, peasy. I believe Eaton just blasted out a bunch to the parts distribution channels. Maybe Lycoming clamps are different and still on special? Price was $800 ish. -dan
  7. Nicely set up and sorted Ovation. Can you elaborate on this? ….asking for a friend :-) -dan
  8. Considering the frequency of prop strikes by both Mooney and TBM pilots, the Ovation is probably an excellent choice to build retract time and learn to protect the nose gear on landing. -dan
  9. I think there is a software update to fix this. Mine doesn'tdo this. -dan
  10. It’s an ongoing problem at the fly-in community we live in. Worse than people walking the taxiways are kids in golf carts. Someone on the board put this sign up. Dunno if it made any difference, but it was attention-getting. -dan (again with the upside down iPad photos…..)
  11. Especially for turbo planes that spend time in the cold teens and above, landing in a humid environment will bring about condensation all of the cold-soaked stuff in the plane. Steel, with more thermal mass than aluminum sheets, is especially prone to this. Electronics like cameras and computers stored in the baggage also can get moist on landing. I fog the plane every annual, and while it is a little “weepy” in places, the only real issue for me would be if I planned to paint the plane in the near future. -dan
  12. Mine did the same. Microkit was very quick to respond. Mine is mounted on the fuselage, just inboard of the step. It does get LOP exhaust residue on it in that location from time to time, and when it does, the behavior is as you describe. A quick wipe, and all is good. -dan
  13. Welcome, Paul. There is a group that gets together for lunch all over florida; it would be great if you could join and meet some fellow florida mooney people.
