    Piper Arrow at tie down with dead battery...how to charge?

    Hand prop it and charge it in the air.

    Leaning to peak EGT

    I use fuel flow based on my MP setting, so I guess it takes care of itself. But I rarely fly above 3000' so I don't need to pay too much attention to altitude. My control of EGT is primarily to control CHT, and in my planes there's a clear correlation. Honestly I could set fuel flow based on CHT...

    Leaning to peak EGT

    Do you know your airplane well? I don’t look at EGTs. I look at fuel flows. Fly your plane enough to correlate them. Much easier and faster for me.

    Putting CamGuard to the Test

    They (Camguard) published ASTM test results right from the start.

    Putting CamGuard to the Test

    I’ve used Camguard for years and have no issues with it, but I do wonder how Cortec Vpci-336 compares to it. I have and use both.

    Best accessories for Mini iPad 6: Screen protector, cases, and mounts

    No screen protector. No case. My mount is self-stick velcro. Works great for two iPads in two different airplanes. Both are wired. In the Cessna it fits right over the top of my old Aera in a Gizmo mount. In the Cub I screwed a Lexan plate to the panel above the G3X.

    Internal engine pre-heater--opinions?

    A Continental’s cam isn’t submerged in oil, if that’s what you’re implying. It does sit low so isn’t in the condensation cavity like a Lycoming but Continental cams fail from corrosion, too, just not at the rate of Lycomings. I built engine dehydrators for my planes now that they live indoors...

    Internal engine pre-heater--opinions?

    Try that on a Lycoming. Continentals aren’t immune but they do have better resistance to cam cancer. In any case, it’s a poor way to preheat cylinders. The colder the ambient temps the more that’s true. Air cooled cylinders are designed to be cooled by outside air. At any rate, y’all should do...

    Internal engine pre-heater--opinions?

    Bottom heat promotes corrosion. Geography has nothing to do with that.

    Internal engine pre-heater--opinions?

    That heater won’t burn 6+ quarts of oil sitting in 250# of chilled steel and aluminum. I wouldn’t use one on its own any more than I’d use any sump heater without a top heat addition.

    Cold Start Screw up?

    If the cylinders are cold enough to concern you? Prime for the temps (cold requires more prime) and pull the prop through several times to distribute the fuel and give it time to vaporize. Exactly what we do when hand-propping. It works in cold weather for cold cylinders and weak batteries, too.

    Cold Start Screw up?

    If you frost the plugs you’ll know it because it stops firing, and just spins. What’s next? The only solution is to heat the engine, and it takes longer to correct it than preheating would have taken to prevent it.

    Cold Start Screw up?

    You should. Cylinders work best and last longer when approaching 400* in normal ops. Cooler isn't always better. PS- Continental says >460* is overheating. Lycoming says >500*.

    Cold Start Screw up?

    I think internetters should just agree to preheat to 350* CHT and 180* oil temp before considering engine start. To an engine that operates at those temps? 70* is cold. Forget about what the engine manufacturers say. The internet knows what's best!

    Want To Buy Engine dehumidifier

    Build one. So simple. Read through this thread on Supercub.org. I built two using parts from Anazon. Cheap, easy, and VERY effective. https://www.supercub.org/forum/showthread.php?58536-Engine-Dehydrator

    Cold Start Screw up?

    Life-long Alaskan. I preheat primarily to ease the stress on the starter, which assures the engine will spin and start. On days when I don't have time? I go by the manufacturer's published limits. FWIW I don't even consider preheat until below 25*. And then because I'll have other pre-flight...

    0-360 engine question

    Anchorage area? What type is the plane? Hangars don't help with occasional use corrosion but it's a total crapshoot why some engines rust and some don't. You'll need to accept that there's always a risk when buying a plane. Roll the dice or don't. There's no sure answer. I bought an 0-320 from...

    Is the data plate the aircraft?

    I built a brand new PA-12 about 15 years ago. The only used parts were a spar and a couple of wing ribs and those didn't come from the original -12. I swapped the data plate to the new PMA airframe. Perfectly legal. Then I sold the pre-rebuild logbooks for $4K. Why anyone would pay that for them...
