    Cowling design - preflight & maintenance access

    I am looking for ideas/best practices for cowling design with respect to access for preflight & maintenance. If you have a cowling like a 172 or an RV, how often do you actually take a look under there? I quite like the convenience of something like a Bonanza cowling because it makes it so...

    Books for a cold winter evening…

    It’s about ten degrees below zero outside tonight and I am thankful to have a working heater, a comfortable chair, a distilled beverage of moderate quality, light to read, and a good book. Tonight Messrs. Perkins and Hage are my teachers. Mr. Roncz is on deck on my bedside stand for later. It...

    Draw-through Turbo Detonation

    What are the limits of pressure and temperature to avoid detonation with 100LL? This is specifically related to a carbureted, free-floating draw-through turbo setup without an aftercooler. Yeah, I know that's stone-age stuff. :) Consider these cases I calculated with an imaginary engine as...

    Airplane For Sale Mustang II for sale

    A friend just listed this on Barnstormers - $9k. I looked it over this morning. The workmanship looks very good. Great head start if you’re looking for an affordable RV alternative. There is a set of blue line plans that appears to be complete (you’ll need to verify of course since I’m not...

    X-66A

    This looks like a 60-year old airframe with its low wing replaced by a high wing with struts. What am I missing? Why is this an advance?

    Taildragger resources

    My instructor recommended the book "Compleat Taildragger Pilot," and I see it's also been recommended here in a couple of old threads. What other books you recommend on the subject?

    Can you ID this plane?

    Anybody know what this little single-seat taildragger is (not the RV)? I hear it's called the "Buckshot" but I can't find any information on that type (perhaps that is just the nickname the original builder gave it). I am told it shares some characteristics with a Swift (see leading-edge slots...

    Unlimited Air Racing Dead?

    It’s been discussed in the past, but I think perhaps we’ve reached an inflection point. The Reno Unlimited purse no longer seems to attract anything but stockers. It’s a far cry from what it was only a few years ago, let alone 10, 20 years +. Witness today’s outcome, with places 1-3 taken by...

    Strength by species

    From time to time, the relative strength of wood species is discussed here at HBA. I recently ran across the following video from Fisher Flying Products. Below I have transcribed their results, which I find questionable. Although the weight of the test samples is mentioned, interestingly...

    Riblett on Twist

    In Riblett's GA Airfoils section "Design Notes for Tapered Wings," he asserts that NACA's conclusion that tapered wings stall at the tip first is invalid. The reason he gives is that not only the planform of the test specimens was tapered; the section thickness was tapered from root to tip. He...

    Centroid & MOI of conic section

    Anyone have a convenient equation to find the centroid of a section of a non-elliptical conic thin shell and its moment of inertia (Ix)? If the curve is elliptical, like the one above, I can find Ix of the fuselage skin by subtracting the Ix of the inside of the skin from the Ix of the outside...

    EAA video: members only?

    I just noticed that EAA put a lot of their previously-free video content behind a paywall. This is disappointing. When I first got interested in homebuilding I think I watched every Hints for Homebuilders video they had at the time. I bet others have been introduced to homebuilding the same...

    Class D incursion?

    Once upon a time, I was a passenger in a plane landing at an airport just outside class D airspace. While alone in the pattern, an unknown voice came on the CTAF and said, "aircraft turning base, you are in the class delta." No identification of the transmitting party; just, you're in the...

    DT6 F1 Racer

    Just came across this new racer. Don't know whether "Composites" is the right place for this, but it looks neat. Good to see another new design in F1. Anybody have thoughts on the 5-bladed prop on an O-200? http://trianoracing.com/

    Pazmany Efficiency

    Does anyone know what years the Pazmany Efficiency Contest was run, and if there exists a comprehensive table of results from all years? My (admittedly brief) search could not turn this up. I know that a score of 13+ was achieved in '78, but I would be be interested to learn the highest...
