    A Wind Turbine Design Application...looks neat!

    Call this kind of slightly off topic, but for you wind turbine fans (no pun intended), I just found this engineering application literally a minute ago. https://qblade.org/ Makes one wonder if it can be tweaked to aid in, say, rotor/prop design? Maybe I can set up a cycloidal or Darrieus rotor...

    Velocity/Cirrus Side Stick layout- requesting drawings or photos

    Trying to get some photos/drawings of the mechanical setup of the Velocity or Cirrus's side-stick control configuration, namely from the stick to just forward of the instrument panel as it splits out to the elevator/canard & ailerons. I have a pretty good idea of what it would be, but I want to...

    Seven accidents in seven days...I honestly thought this was a satire article!

    I honestly thought this was a satire article...until I read the NTSB report and the "statement" of the pilot. Pro Tip: DO NOT BE LIKE THIS GUY....EVER!!! https://generalaviationnews.com/2023/09/06/seven-accidents-in-seven-days/

    Lancair IV Skin Thicknesses

    All: Curious question on molded skin & rib thicknesses on the Lancair IV. Anyone have a good idea what the total skin thicknesses are for the skin (with core material) as well as the ribs? What about those areas where the joggles are; what are the non-core skin thicknesses? I am assuming...

    The Great FreeCAD Thread

    All: I have seen so much discussion on FreeCAD here lately, and being one of the users, having converted from AutoCAD recently and see this as a very capable alternative to 3DExperience and Fusion360, I figured it would be a good idea to start a thread. Some ground rules I think are...

    Gemini Diesel: Anybody heard of these folks??

    Fam, we were having a light aircraft engine discussion at the office (in the breakroom, of course), and one of our Rolls Royce engineering reps pointed us to the Gemini 100 and 125 engines. https://www.geminidiesel.aero/index.php/aviation Anyone here heard of these folks? Is this another...

    Active Fuel Management / Cylinder Shutdown: GA Potential???

    So, after an 11-month wait, the Mrs and I recently took delivery of a new GM sports car. Of all the things about this car, I’d have to say that the one thing that fascinates me the most is the LT2 plant that sits right behind me. In particular, I am extremely fascinated with the fuel economy...

    Lost Pilot Logbook....How to Deal with it.

    After doing a quick search and coming up a little empty here, I elected to throw this one out there.... Last weekend after coming home from a flight, the Mrs and I were unable to locate our logbooks. After a brief thrashing of the home office, we found them...right where we always have them...

    Mosquito XE: What a Blast!!!

    Wondering if there are any other Mosquito drivers here on HBA. I recently finished some post-assembly testing on one for an old friend. Most fun I ever had flying a helicopter!!

    YouTube star plays stupid game, wins stupid prize...

    Pro Tip: If you are going to intentionally crash an aircraft for the sake of social media likes, assume the authorities will take notice! https://www.nytimes.com/2022/04/20/us/trevor-jacob-youtube-plane-crash.html...

    YouTuber under FAA Investigation for seemingly deliberate crash...

    Flat-Plane Crankshaft Engines...a discussion!

    For those who follow automotive developments, the talk of the town is the imminent unveiling of the 2023 Corvette Z06. What is most noteworthy is its Ferrari-esque high-pitched scream, as heard in the clip aired a week and a half back: Certainly not the classic brute-force grumble typical of...

    Yamaha YG4i (Apex) Data Collection

    Ok fam, we have a baseline vibration spectrum on our converted YG4i - SkyTrax PSRU combination after refurbishment, overhaul, conversion and dyno runs. The conversion was nowhere near as complex as we thought, and the engine ran like a dream on the dyno. The plant is now preserved. When we drop...

    Kawasaki superbike-derived UAS engine now on scene. Yamaha Apex alternative?

    Just saw this on YouTube, fam: Looks like a pricey alternative to the Apex, but I think it may be safe to assume it is coming our way. I'll be sricking with my Apex YG4i plant; I'll rip the sled apart and pull the engine once I get all settled in up in MD! But, is anyone here familiar with...

    Anyone here living in an Airpark Community?

    I think we found our dream property. 2200 sq ft home, built above a hangar, with a 2 car garage...and a paved, lit runway running right down the middle of the neighborhood! Not far from work, either! Only problem is that it has never been lived in, owned by the bank as a foreclosed, unfinished...

    Lippisch DM-1 airworthy faithful replica...

    Not so much a warbird...but is a warbird-era concept... So, a very close mentor reached out to me earlier today. Had a discussion regarding what would it take to engineer and construct a 100% faithful replica of the Lippisch DM-1. Naturally, I gave the appropriate response, ie, poring...

    @Dana @BJC @Direct C51 @CRG @Victor Bravo @wsimpso1 Okay folks, a couple remarks and some ground rules before I get into my opening statement… I am sure there are plenty of related threads to this topic, and I apologize accordingly, but I elected to start a new one, because I think...

    Any St Mary's/Calvert County MD members here?

    So, I was notified that come 1 October, American Airlines is showing myself and over 6,500 of my peers the door. (You'll be hearing about a class action lawsuit soon enough, but I'll digress and let the ALPA handle that piece!) I have, however, been interviewed and hired to come back to the...

    Planning to construct a good composite curing oven...request some feedback/input

    So, looking ahead to our full scale build, we are researching the idea of constructing a curing oven. From what I have seen across the interwebs, I see this concept popping up: https://www.smooth-on.com/tutorials/build-hot-box-oven-heat-curing-materials/ Or this: Seems straightforward...
