    Yeah, I like to experiment. What might not be suitable for a full size airplane, might find a use on RC airplanes.

    I brought some weird plastic mesh home out of a dumpster at work to see what happens when I laminate it for tear stopping power. Like screen door mesh but bigger holes, that should let the laminate bond to itself on the other side through every hole and won't delaminate like tyvek from the inside. Looks like I need to heat it in an oven up to 300 for more melting together with less air entrapment. But oh yeah, does this black stuff stop the tears dead in their tracks. Into the oven with you...

    [​IMG]

    Maybe the black stuff is a winner, but upgrade or ditch the laminate plastic for an alternative. Or make the plastic black grid already filled in with the same material it's made of, only thinner inside the squares to save weight. Not that it's heavy.

    Whatever this is, its new but still imperfect, like mashing peanuts together to get a proto-peanut butter. Some inventions are so daft as to be nothing more than squashing peanuts. I mean, what is a paper clip or a cotter pin, but nothing but a bent piece of little wire. A nail, for that matter...

    So yeah, this is completely stupid, but...

    A test sandwiched between packing tape produced less favorable results.

    The oven experiment was interesting, it made both materials "shrinkydink" but remained flexible... the black pvc mesh in particular... (now thicker per square inch and even harder to tear) maybe less heat and sandwiched between two cookie tins with a weight on top...

    What I need for an airplane wing, is some lightweight strong way to fill in the holes... without manufacturing the same grid filled in from scratch. Ideas? I like the laminate idea tho, some other material that has complimentary strengths in other areas the pvc grid material might lack.

    I wonder how well it stitched together would hold... maybe high test fishing line? Anyone used that on a plane?

    Maybe tomorrow I can set up an inch strip weight test rig (12am).

    Further animation weirdness...

    Since I have too many airplane projects...

    I decided to give one away on Craigslist...

    since I literally sat at work and watched another count down on my mobile phone and passed on buying another one for 99 cents, for lack of interest on my part in driving down to FL and loading it up...

    If you are of the mindset, that interest in aviation is dying...

    and that common people don't still dream of flying...

    My inbox has been blowing, blowing, blowing... up...

    [​IMG]

    This is how you promote home built aviation, and get people excited about flying :) *mike drop*

    I see a lot of girls in there... didn't expect that.

    "aa aa" in that screen grab turned out to be our very own Derswede...: :p

    You're giving away the Chotias? They're ideal for Dorothy.

    Nope, keeping the engines. Unless whoever I give it to actually restores it all the way to the point of needing an engine and being ready to fly, in which case I'd most likely give them one just to see it fly and get second propeller just for it.

    So, how do you find all these airplanes for sale or free. Every time I check out Craigslist, I find a few planes and a bunch of un-related stuff.

    Even for free, some things are worth less than the price.

    A good friend of mine, a younger (than I) Pilot, who owns his own 'Carbon Infusion' business, with considerable experience with boats (large Carbon Catamarans 40ft. and racing Catamaranes). as well as a host of other Composite development, has decided to build his own Carbon Cub - in Carbon Infused Flat panels, including the airfoil. Although very smart, his knowledge of Aeronautical Engineering is extremely limited and I help where I can, but his approach is also very DIFFERENT to what most expect and may indeed work - we test the wing to 6 G x 2 Safety Factor, next week. This should prove the strength or otherwise of his approach, but I'm starting to think it may well be a very cheap and easy (and light) way to make an Aircraft.

    I have real concerns about getting the airfoil USA 35B at 11.6%, to bend over ribs, however the D nose section will be a separate lay-up piece and attached after the main wing section is glued and clamped into place and he is right there's not a lot of bend in that section of the wing. However Carbon is notoriously hard to bend and I have made other suggestions to eliminate the bending of a finished panel, by keeping some elements separated until the last step. This would require a 2 layer bent over the Ribs (bottom layer of a Top Skin) which will bend easily and a separate overlay of the foam and top layer of Carbon.

    I considered eliminating the foam, but had to consider the effect of flexing even with a strut supported wing. However it may just work without the foam, but may also be prone to damage, given the nature of Carbon and maybe something we need to test for.

    If you look at the Horizontal and Vertical Tail Elevator and Rudder, their all flat panels, with radius edges. The fuselage panels are flat and can be taped together, the bulkheads an seats can all be flat panels.

    Probably one of the big issues in this approach is getting the panels cut to size, as he has a very large CNC router, so this isn't a problem, it should go together like Leggo Blocks. Maybe, just maybe he's onto something - I will let you know.

    Narfi, I've had that same idea. A stitch and glue plane would be pretty awesome. It's such an easy way to build, and could be really light since a plane wouldn't need as thick of a skin for impact protection as a boat does. Or maybe a hybrid type of thing with an S&G fuselage and a traditional wood wing (with lots of wing area, I'm thinking wood and fabric would still be lighter)

    I don't do anything special, I just read through listings, and not very religiously... rather sporadically and randomly, actually... the key is to look at everything nobody sees, and for listings that are mislabeled... and I like to look for ugly ducklings and pariahs... for example, the guys here think an Affordaplane is a poorly designed deathtrap for various technical reasons, in the same way I think a Gee Bee Racer is a death trap (and they would disagree with me).

    What that means is, there can be an Affordaplane project here posted for a song, right out in the open, and nobody will touch it, they will poo-poo it and turn up their nose at it, and you can be just like Sir Mix-a-Lot, swoop in and retrieve it. No joke. Maybe you will never finish it. Maybe it is a death trap. But it doesn't matter. Because if you have no plane, and you get a plane, guess what, you got something in your hands now. You're not a dreamer, or a talker any more, or a theorist, or a paper napkin sketch artist. You've got airplane junk in your garage now. Or in my case, right out side my front door 5 feet off my front porch. You're now in the club. You can touch that hardware and see how some things are done. You got something to work with.

    Probably the third helpful thing, is to have a lot of eyeballs (friends) watching the net for you that you regularly trade aviation finds and links with... which I do on a constant daily basis with my friends. I'm what you call a noisy sneezer... I stumble across cool aviation links, I sneeze them out to my friends, they find the same, and sneeze what they find back out at me.... all throughout the day. All you have to do is tab trough the Big Video Topic to see me in action.

    And cheap plane projects are not rare. There are tons of aircraft projects started by guys, that never got finished, the guys gave up on them, and now they are in their 60's, 70's, 80's, 90's whatever. They may not be listed at all. As such, you are not a thief, you are their last best hope to get whatever they started, ever flying. When you are that, and legitimately that, they will literally shove the plane on you like a last ditch football pass, so that what they started will someday fly.

    These unfinished plane projects, they are big, they are bulky, they get in the way of their sons and daughters cleaning out the garage of their parents house they just inherited, to park their bloody KIA in there. Or their dad's hanger, because they just sold it, and the new owner don't want an unfinished Woodhopper plane project in there, it gets in the way of his big shiny metal Cessna Citation. Where does the Woodhopper end up? On Barnstormers for $99 for everyone to see. Who actually gets off her butt to go pick it up? Well, moi, of course. Because that kind of Choppergirl Special is about all the plane I can afford at the time. For $99, I can give it away free on Craigslist, and boom, now 150 new people are suddenly excited as hell about aviation. So suck it, local EAA chapter, I just got more people excited about flying, than you have in the last 10 years!

    Plus, I got one more wild card in my own personal deck. I'm rather infamous, for better or worse. And I'm a girl. You give your plane project to me, and you can be sure, I'm going to promote it like crazy and make it famous because I'm a guerilla marketer. I may even do something notorious with it. It could very well end up in the history books for good or bad. You just never know ;-) Today's nutty idea for example is to go for an ultralight flight distance record by towing an extra gas tank behind the plane like a Bell X-1 looking drop tank glider. Is that 103 legal? Dunno. It's not part of the main plane. Let's test it! Will I have another idea tomorrow? Probably.

    One hot potato most overlooked, are those two place ultralights derelict in barns that are no longer 103 compliant. Nobody will touch them. But guess what. Nice engine on them. Nice prop. Expensive redrive. I bet they could be chopped or bobbed down to get under 254 or one of the seats thrown off and boom suddenly it at least looks compliant. Or you could moved it from here to Brazil where they are legal. If I had my druthers, I'd buy them all up until I couldn't pack one more onto the farm, then I'd petition the FAA to make them legit 103 again, and be sitting on an empire of planes that just jumped up in desirability. Who doesn't want to take their date on a flight? I'd kill to be able to take my dates flying in a two place - land anywhere on the side of a farmers field hill on a weekday when the world is at work, bust out a picnic blanket under the wing and a picnic basket... after lunch, land on a sandbar, do some swimming or wading around... fly through some clouds on the way home... they'd never forget that date.

    I myself know of one local cache of two place ultralights owned by a codger that use to have a school to train people to fly them... now, he flies trikes and is getting way up there in years. Guess where all his school's two placers are, in a barn. Guess who's going to offer to clean them out for him free of charge, so his children and grandchildren aren't burdened with that mess :) How did I find him? He found me. Because I plaster out my shingle everywhere.

    And most importantly, consider everything, even if it's something you never thought of wanting or owning.... esp. when it falls into your lap and is super cheap, or free. It will expand your world. It don't have to say bloody VANS or RANS or whatever on it. Tunnel vision will vastly shrink your choices. Be open to saving an entire range of aircraft out there.

    Did I ever dream of wanting this platypus duckbill snout looking thing below? Heck no. But you know what, it was free, and it looks like it flies to me! Wrap it up, I'll take it... and love it, and one day, fly the heck out of it.

    [​IMG]

    Can you believe when I first started out, I was so desperate to get my hands on any airplane, and the aviation community operated from such a paradigm of stingyness, that I was trying to hunt down the likes of C-FFAM buried in a playground?

    I grew up surrounded by oceans of obsolete computer equipment - today state of the art, tomorrow junk to gift and trade and barter or even give a whole system (which I often did) to someone starting out - and if something died in it and you needed a video card, harddrive, mouse, power cord, power supply, etc... here, have one, I got 100 more in the barn. My dad brought home tons of computer equipment homeby the pickup truck load, from colleges and businesses upgrading, to keep it out of the dumpsters so it could go to... somebody. Our friends were computer techies who also had a closet or storage shed in their back yard full of old PC cases and motherboard. You trade, you gift each other, you make friends, you even start careers, the hobby expands and flourishes, you all benefit.

    Aviation just shocked me... nay, appalled me. It still does, to look at the absurd prices for old junk on Barnstormers... a steep hostile toxic barrier... hoarders... keeping everyone new to the hobby... out... something is wrong with you guysss......

    Since I last posted, I have actually seen a couple of these deals. I just wasn't looking hard enough ! Keep at it gal, for surly one day, you will be flying your own airplane !

    Narfi, Yes! very astute of you, we both have Vision Plans from Steve Rahm. Steve is a real Gentleman and had a wealth of experience in Aviation. I assume my friend did initially get the idea from Steve's plans, however he does a lot of flat panel extrusions in his business. For myself I've moved on to a Carbon Tandem (Fighter) designed from scratch, however in the process I evaluated Steve's design and it met all necessary safety, strength and design criteria. I tried unsuccessfully to get Steve to go Carbon, initially with the Spar design without success- now it seems it's happening, with someone else taking over the business.

    The biggest attraction for my friend, is the simplicity of the design.

    Fred, someone very knowledgeable on HBA suggests a top skin to have a minimum of 3 layers of Glass for Impact resistance. Carbon being much stiffer maybe 2 layers. Leading edge should be more robust - obviously.

    for some lip gloss for the Poorgirl...

    Aviation is Dead or Dying!

    Some of the emails with a little more content than basically "I want your plane! Here's my name and number!"

    No I think it is a really big robot with a person inside its core controlling it at the casino.

    I saw a laz-air a few days ago. A bargain at $8,000.
    Ok, it does fly...
