  1. The AV-30 has an installation options page which allows you to precisely adjust the roll and pitch zeroes. The latest software update appears to have addressed the tendency to show a turn in the opposite direction when leveling out from a long sustained turn. I believe this was caused by a routine which mimics that same behavior in a vacuum gyro being a bit too aggressive, but nobody from Avidyne has confirmed that for me.

  2. Don't get hung up on EGT. The number will change based on ambient conditions. CHT is the critical number. If you're seeing no higher than 400 during a full power climb, you're doing it right. The EGT numbers will vary as much as a couple hundred degrees between aircraft, even running the exact same engine, mixture, and power. This is because there is no fixed/measured position for the EGT probe in the exhaust tube, and each probe has its own thermal properties. The EGT for my plane at a given power will not be the same as the EGT for yours. Sent from my Pixel 5a using Tapatalk
  3. That's not a momentary switch, it's a toggle action/latching switch. Sent from my Pixel 5a using Tapatalk
  4. Say mean things about it until it shrivels up enough to be removed. Sent from my Pixel 5a using Tapatalk
  5. I believe that in both cases, the control on the dash just moves a valve on the pump block via a cable. I would expect that the lever assembly should functionally work perfectly well in the place of the knob assembly, though you probably need a good amount of hardware for it.

  6. If you put an F tail on a C, does it also get the F VNE rating, since VNE on the C is limited by stabilizer flutter? Sent from my Pixel 5a using Tapatalk
  7. I wouldn't go for the 430. Garmin has been working to kill it off and coerce people to upgrade to a newer model line for years. If something ever breaks in the 430, you'll be hit with a flat-rate repair charge for it (until Garmin discontinues that service), and the price for that repair has only been climbing. Better to save your money and buy a unit which is still actually in production. If your panel has space for a 430, then it also has space for an Avidyne 440, which uses the same tray. I don't know the autopilot compatibility of the Avidyne off the top of my head, though. Sent from my Pixel 5a using Tapatalk
  8. That sounds like a good enough reason to do it to me. Sent from my Pixel 5a using Tapatalk
  9. Fair enough. Is that small increase enough to change the cylinder temperature enough to warrant a richer charge? Sent from my Pixel 5a using Tapatalk
  10. Why? The power flow exhaust doesn't increase the air charge coming into the engine, it only reduces exhaust restriction and improves scavenging. The power increase it provides isn't the cylinders making more bang, it just reduces the power wasted forcing exhaust through the inefficient factory pipes, leaving more of that power to exit via the crankshaft instead.

  11. One thing to watch out for with paved ends: the transition from pavement to dirt will erode rapidly and dramatically compared to the rest of the dirt, especially when it rains. You'll need to regularly inspect and repair those transitions, if you go that route Sent from my Pixel 5a using Tapatalk
  12. Sounds like a failing master relay. The switch on your panel doesn't energize the panel, it only energizes a relay which energizes the main bus. Sent from my Pixel 5a using Tapatalk
  13. Pull the suction screen and check it for debris. That much of a drop without a change in engine RPM suggests either a leak or a loss of oil pickup. Sent from my Pixel 5a using Tapatalk
  14. Maybe sink a well to supply a drip-style irrigation system to keep the dust down? Probably cheaper to just pave the runway. Save you from replacing blades. Sent from my Pixel 5a using Tapatalk
  15. The -A1D on our C models does not have a primer pump. It does have an accelerator pump inside the carburetor, however, and that is what 'primes' the engine when you tickle it with the throttle. That said, our carbureted engines are usually pretty good about starting up, as long as there is fuel in the carburetor bowl, unless it's very cold outside. What I suspect may be the case for you is that you had a car of vapor lock in the line between the fuel tanks and carb bowl. The electric boost pump is a rotary vane pump and incapable of self priming. If you get air in the line leading to it, it won't fill the carb bowl in prestart. When the happens, the carburetor won't get any fuel until the engine has been turned over enough times for the mechanical pump (which is capable of self priming). This can feel like a VERY long time if you're used to the engine firing on 1-3 blades. Did you happen to notice if you had fuel pressure after running the boost pump, prior to attempting to start? To test your accelerator pump (before you go ripping things off) 1: start the engine 2: warm it up to normal temperature 3: do your run up procedure 4: full rich mixture 5: advance the throttle briskly (1 second from closed to open, smooth motion). The engine should accelerate without any hesitation or coughing. If it does, the accelerator pump is fine, and your starting issue was most likely related to air in the line.
