  1. 23in/2400 rpm ... 9gal/hr nice and quiet
  2. Wonder why the 12V are so much more expensive than the 24V plenty of 24V on eBay for very reasonable rates I purchased a spare a while ago seeing how that was trending
  3. An AI like a 52D56 is 2.7 lbs A 215CC pump is 3 lbs the vacuum regulator would be 0.5 lb if I was to guess (you probably have one ) the 5/8 hose is 0.25 lbs per foot ... I am guessing between the hose going from the pump to the firewall , and the two hoses from the back of the AI , you have about 3 ft or about 0.75 lbs the low vac system is mostly wiring so maybe 0.1 lbs ?. The AN fittings probably 0.1 lbs add it all and probably around 7-8 lbs
  4. Check the weight of all the components and add ... I am guessing probably ball park would be around 7-8 lbs between the gyro, the pump, the air filter / regulator , hoses and low vac warning in my opinion , the biggest benefit is less clutter behind the instrument panel and in the engine accessoires compartment
  5. I am surprised that there is no service letter saying that flying may lead to an unsafe flight condition
  6. understood. but if on the skin, you would need a few washers on the fuselage side of the GMU to level it
  7. Page 66/67 of the latest manual ... the GMU cannot be installed on an inspection panel the GMU has to be +-3 degrees of the roll axis ... i believe the Mooney has a “nice” dihedral angle ... so if you put it on the skin , you may have to put a few a few washers to level it up . Probably not a big deal anyways. when it ain’t broken , don’t fix it
  8. I believe I read in the G5 install manual that you actually cannot do that
  9. A 10 degrees error would not be unusual for a standard whiskey compass I found it odd that changing the alignment would reduce the error in one direction and increase it in other direction. You have interference in where the GMU is located
  10. what is for sure is that you cannot install a G5 and get rid of the whiskey compass I would find it surprising that the post would have become magnetized all of a sudden after the repaired compass was reinstalled my suggestions would be: 1) make sure you don't have something like an iphone/ipad near the compass 2) see if you can borrow a compass known to work and test it (short of buying a new one)
  11. Reading the previous post : if the magnetic heading you are getting changes when you switch on and off some other electric equipments, then you have the wrong location for the GMU and you need to relocate it to a place with no magnetic interference if your magnetic heading is just off (vs a compass card painted on the ground at an airport) but does not change when you switch on and off electric equipment, then your GMA is not correctly aligned Both cases are addressed in the install manual A paper correction card (like you have for a whiskey compass) will not solve you
  12. Just curious whether the February shipment was your choice or the lead time from the factory
  13. Maybe I don’t understand what you mean but my thinking is : the only instrument that requires a card is the whiskey compass any other magnetometer based compasses (HSIs) have a calibration procedure to be within 10 degrees max (I think that’s the right number for the G5 if I recall well) if that’s not the case , your GMU needs to be realigned (I had to do that for my G5 using washers)
  14. The plastic that has PG and SEL on them are actually caps behind which the screw is
  15. You need to pry out the caps (the caps that have SEL and PG on them. that cover the knobs. Use a blade or a tiny flat screwdriver for that . Make sure you don.t loose those caps . then use the tool pictured above to remove the knobs. Hold the knob and unscrew with the tool above (it will be straightforward once you uncap the knobs
