Affordaplane part 103 legal plans built ultralight aircraft

[Music] [Music] that's right this is a airplane I designed I started March 27th last year and I built it in a 1-bedroom mobile home 19 foot porch bite foot and it's just my idea of what an ultra-light should be and its plans built we're gonna offer plans and it's got a row text 277 it can use the 377 or 477 high wing and it's just a really basic simple ultra light and very strong the fuselage is square tubing 2-inch square tubing 60 63 T 351 is what it is you could use t6 tubing also eighth inch thick eighth inch thick gussets there's two common size bolts in here the entire airplane is is quarter inch bolts and three eighths inch bolts a and three and and four it's designed to be within FA r103 regs it does weigh 254 pounds it really weighs 254 pounds and just common hand tools all I had was a drill press some files I had a dremel sander which was probably the best thing I had for the entire construction dacron fabric 1.7 ounce and we also one of the unique things about this is we used the Jerry bunner method of fabric covering of painting to paint the airplane all of this is latex house paint mixed with a chemical called floor all that makes it flow really smoothly gets inside the fabric seals it and then you you do three coats of base to fill the weave and then you do three coats of color and you use a color enamel enamel color automotive enamel for the top coat and if you've scored it with armor-all or any other protectorates it'll last just as long as it as a factory finish it probably won't last as like ten years or 20 years for Stitz but it will last long enough to where you know I painted my airplane 50 bucks instead of two thousand notes oprah lights cost you know so it's a good way a good inexpensive way to get in the air and and it works great well that's a good question because you can use stainless pop rivets you can use stainless steel pop rivets instead of all these bolts and I'm sure you'll you'll you'll get a good look at it in a minute but we use all a and three bolts that run through sandwich construction and you can use stainless pop rivets but you wouldnt be able to take it apart this way if you use the bolts you can take it all apart but it will be a lot lighter with with just the stainless rivets it's a lot like the kit box in a way the these wings now are foam with one millimeter ply cap strips and they've got blocks in between to hold them up right for the loading and everything and then you just glue the fabric straight on to the ribs with Polly tack and now I'm trying to get away from rip stitching because I hate the rib stitch and everybody hates rib stitch and that's just an idea I had the plans will include the wing ribs will be an inch and a half wide with inch and a half wide cap strips and you can you know then you can have much more bearing surface and everything you know surface or the field and all that but originally we had aluminum to grips drifter type or compel a challenger any of those kind of ribs would work and you've got the diagonals in the cross brace it's just like any other ultralight wing and it's got a Clark y airfoil on it no actually what happened was last week we we had an accident and the tailwheel we had a problem with a tailwheel we had a gust to win at the wrong time and it took me into another airplane and the way she sits now she's not she's not completely together yet but we were week before the airshow and we were just doing the test flights and I have flown her she has flown and I knew I needed to change the wings curvature a little bit so we we just bit the bullet took her home and redid the wings and got a much better shape for the airfoil and just the first hops I did you could tell a complete difference in the airplane but we should release plans you know today is the 9th of April 2000 we should have the plans out I'd say within a month or so from now they're about 90% complete and once the flight test is done once she's completely tested then we'll release the plans yeah there's there's almost 35 sheets of I think it's 28 by 11 every fitting is full size every every part you need that normal like the ribs are full-sized you don't have to you know build anything draw it out to be bigger you know there's a complete Builders manual from A to Z with pictures it describes every single aspect of airplane construction even if you've never picked up a wrench or anything you can look at the plans and they'll say this is how you draw a tube out this is how you mark a tubing to be square this is how you drill a tool but you know tubing this is how your deeper a hole it'll show you everything and we've also got online support we've got a extensive website that shows how to do every how this was the concept all the way to the finishing parts but how is finished yeah well we have a complete list of materials and we also have on the site we have a section for builders where they can go and they can trade stuff and buy parts and things and and they can find out the best prices we have a section where they can go and anybody that's got the best price for whatever they found it be it will Barrow tires or tubing or square tubing or an engine they'll they'll post where they got that that tubing at so everybody's always guaranteed to get the lowest price right pretty much yeah well they what I did was it's kind of a unique control system because I've got a torque tube running from the stick there's a torque tube that runs underneath the seat and it's got a bell crank and the bell crank runs up with turnbuckles where he could use push rods to turn to it's got turnbuckles in it and it goes up to the fittings on the ailerons which actuates the ailerons it's a real simple really light and it's really solid in the air it can't go anywhere you know so so that works out real well there right now is it can be their cable or it could be a tube the tube weighs a lot and it'll probably you know it's going to get close to the weight limit so we're probably going to go back to the cables with a pulley system and that'll work just as good and be a lot lighter building times in here for me it took being a prototype as you as you well know it is taking me five times as long to build it in five times as much money but you can build this airplane from plans roughly I'm saying 250 hours now which you know everybody laughs at because it usually takes a thousand hours for any airplane to be built but but what we're gonna have is we're gonna have people that are building them now they're gonna actually document every single minute they spent and that's the exact times I'm gonna put on the site and on the plans so they'll be exact and if it's high and it size people away too bad that's that's the actual truth and that's you know so we'll get an average in the next few months and see see what it really takes to build one yeah well they can they can use a 277 but more likely a lot of people going to use a Kawasaki 440 they'll use a Kosar fairly inexpensive and then come off the Phantom's and things Nick they bolt right on there good way limit anything up to about 85 90 pounds you don't have to mess with anything CG wise so you can use a whole variety of engines for 473 Simpson you know hinges like that because those are still in production the name's David words you can go to my site it's at afford a plane comm you can see everything about that there there's older forms you can order the plans off the site you can see the builders [Music]
