    Asking for advice on how to fix my Kolb

    Greetings all, as you may or may not know I got a Kolb Mk II last December. Thanks to a stroke of wind and bad luck the leading edges got damaged during the trip and now I have to fix them. A couple of guys told me to just patch them up since they are not structural but one of my friends says...

    Metamorphic Wings

    Interesting concept for sure, as for being the future....let's wait for a bit.

    Foldable, collapsible structures

    Greetings all, after one too many beers I had another stroke of genius (isn't that what beer is for, after all?). How hard would it be to take a design like the venerable Quicksilver and make the structure foldable or at least ready to be assembled/disassembled in a few minutes so as to fit...

    Chinese military gyros

    Good idea? I'm certainly not a military expert but while there are some good point to this, it looks more like a suicide mission than anything else. I guess it depends on who your opponent is and what type of weapons it has.

    Truing the crankshaft

    Hi all, I found the below clip about truing the shaft on the 503. I find it well done and educational and I wanted to ask for those of you familiar with this procedure if you would do it any differently and what's your take on this. Is your setup different, similar? Thanks in advance.

    Flying with a piston engine to FL 600

    Vespa carburetor

    Greetings all. I stumbled upon the below clip about 50 cc scooters, and the explanation regarding the carburetor on the Vespa got my attention (it starts at 7:11). Can anyone explain it better, and would such solution work on the 582 or other 2 strokes in general?

    Why is it so hard to be profitable in aviation?

    Greetings all. Following the latest news about Vans, I'd like to discuss why so many companies - quite often with very good products - had to close shop, restructure, be absorbed by others, and so on. My intention is not to open another discussion about Vans, but to find some common points as to...

    Centrifugal compressor book(s)

    Greetings, as per title I am looking for a good book(s) regarding the above subject for the mathematically challenged dolts like myself. After searching in the tech section I could not find any. Many thanks in advance.

    Forgotten engine: the GM X-250

    Very unusual but it seems with very good performance. https://airandspace.si.edu/collection-objects/general-motors-x-250-radial-4-8-engine/nasm_A19820086000 A direct-drive, liquid-cooled, supercharged, two-stroke cycle engine, this General Motors engine was a very unusual design incorporating...

    Rotax 582 inverted

    Greetings all, I saw last week a homebuilt with a 582 mounted inverted. While it seems that during flight there are no issues, a close friend told me that this setup is suboptimal, due to the fact that the spark plugs require much more frequent cleaning. What's your experience/opinion on this...

    Headsets - brands, tips, recommendations, etc.

    I have a pair of Peltor 7006 which are very comfy, but a bit long in the tooth. Plus I need a spare as well, so I was thinking about getting a second pair. I don't like DCs and a friend recommended Bose - which I like, except for the price. Any suggestions, advise? Many thanks.

    Shcherbakov Shche-2

    Since our resident history expert @Bill-Higdon is slacking lately, here's an interesting bird from Russia: https://en.wikipedia.org/wiki/Shcherbakov_Shche-2 Basically a cargo plane for 16 troops with 2 Rotax engines. Despite being quite underpowered it was successful.

    Calling out all the Rans S6 owners

    Alright folks, I found an S6 at a very decent price - it seems, and I wanted to ask everyone who has or had one the good, the bad and the ugly about this sweet little plane. Let's hear it.

    What makes an airplane go faster?

    A car goes faster by increasing the engine's RPM which in turn increases the wheels RPM. So it's basically just a matter of HP. What about an airplane? In my limited understanding there are 3 factors: power, propeller and aerodynamics. How much power you have, what type of prop you have and how...

    Intellectual property

    Alright, let's say that I want to build a copy of this (I blame Jay Kempf for giving me the input): The manufacturer's assets were acquired by another UK company, which went into liquidation about 50 years ago. Can I build one without any legal consequences? Let's skip the market economic...

    Cost index

    Does it make sense for pistons? I'm obviously referring to Bonanza-class planes with turbos. Opinions, thoughts, insults?

    Why aren't Lyco and Conti pursuing the 100 hp market?

    I don't get it, the numbers are there. What are they offering? The same 50 years old engines. https://www.prnewswire.com/news-releases/ultralight-and-light-aircraft-market-worth-11-6-billion-by-2030---exclusive-report-by-marketsandmarkets-301107417.html

    How to measure engine load

    Greetings all, it's me again with another weird question regarding engines in general. Generally speaking we use RPM to determine how hard the engine is working - sometimes the MAP too - however I don't think it's an accurate measurement. Car analogy: I'm driving uphill in 4th gear at 2500 RPM...
