    Price discrepancy in generator to alternator conversions.

    These all appear to my layman eyes to be the same generator to alternator upgrades but the price differential between Aircraft Supply and the other two retailers is simply too large for me to believe they are selling the same thing...

    Landing of Falcon Heavy side boosters

    Always kind of neat, in my opinion.

    My flight lessons

    You mean these guys? https://dogcopilot.org/ If so, seems their "about" web page has some of that info (enough flying to transport 1000 animals a month.)

    Fake metals in airplane parts thanks to China

    Some thoughts: Counterfeit auto parts are a fairly lucrative target market if my searches on "counterfeit auto parts accident statistics" are any indication. All the articles warn of their dangers, at least one claiming an epidemic of accidents, but did not provide a source for that claim and I...

    Painting a yoke?

    Just a followup: I've got several changes in the works for the plane now and decided to order leather covers with PTT buttons stitched in. I need to have the PTT wired into the system but while waiting to have that done I took a try at attaching one of the covers to the copilot side to see how...

    C150L Aerobat arrives in Arizona

    Good to see it arrived safely. I see they put the wheel pants/fairings on!

    My flight lessons

    My modest advice (I'm not a CFI - just a low time pilot): Make sure the trim setting is near the takeoff trim setting when you are abeam the end of the runway on downwind. After reducing throttle to about 1600 RPM it will thereafter slow to about 1500 RPM. I have found that the RPM setting is...

    My flight lessons

    I had about 20 hours in single engine airplane when I soloed in 2010. However, I had accumulated roughly 12 hours (41 landings) in gliders in 2008. I had spent the summer of 2008 learning in gliders and the instructor felt I was resdy to solo on the next weekend. But her full time job as a...

    Tornado video, Greenfield Iowa

    Recent video of a multi-vortices tornado near Greenfield Iowa that suffered heavy damage and fatalities from a tornado (not sure if it was caused by the one in the video.) Audio is distracting IMHO.

    New home office chair

    Would be more authentic if another chair is attached on either side that contain mannequins that hog the armrests and otherwise intrude on your space.

    STC-PMA approved - available with or without the STC?

    Belated report on the bus voltage reported by the uAvionix AV-30: it appears it is reporting about 0.5 to 0.6V low. My multimeter shows that much higher when measuring at various points behind the instrument panel and at the cigarette lighter.

    STC-PMA approved - available with or without the STC?

    The regulator arrived this morning and was already installed and tested by the time I saw your post. The mechanic said the old regulator was only delivering 12V or so. I had already agreed with him on replacing with the solid state regulator rather than adjust or repair the mechanical one. The...

    STC-PMA approved - available with or without the STC?

    Late follow-up: No parasitic drain detected on the battery. After the charger reported it was fully charged I disconnected it and a multimeter measured 13.23V across the battery terminals (not considered valid meaurement for various reasons, but decided to do it anyway.) Fifteen hours later it...

    STC-PMA approved - available with or without the STC?

    Haven't had a chance to test for parasitic current drain yet, but while waiting for the charger to arrive I've been curious about the generator and regulator systems. I ran across this nicely done tutorial on Youtube on how vibrating point regulators work:

    STC-PMA approved - available with or without the STC?

    No more questions - thanks for trying to explain. The starter issue may be something else: I measured the airplane's battery voltage yesterday with a multimeter and it registered only 11.34V (Uavionix AV30 reported bus voltage of 10.4V.) It is a new Concorde RG-25 installed June 11, 2023 by the...

    STC-PMA approved - available with or without the STC?

    I did not notice much difference in flight characteristics, though the early 172s use a Johnson bar to actuate the flaps rather than an electrical switch. Also, access to the baggage area requires folding down the back seat, while later models have a side baggage door. No rear facing window is...

    STC-PMA approved - available with or without the STC?

    Sorry, I should have been clearer in my post - the italicized quote came from the B&C web page, not from your web page. I linked to your page because I considered it very useful if I chose to try and adjust the existing starter than replace it. The B&C starter was first STCed and they later got...
