This man unfortunately because he is both a very energetic family head and obviously cares for his property well is on the way to killing himself if, he puts enough power on his assembly and it ever leaves the ground. The faults in the wing are way too many to catagorize here but perhaps this man is making a spoof video to get ratings. If you know this guy and he is serious please get someone to explain to him the basics of aerodynamics and structural engineering before he kills himself.
Dont listen to those negative comments.. if we were all scared not to build something because of safety, then we would still be on the ground by now. Chinese farmers built helicopter and planes, the drug cartel in Mexico built a submarine. If we wanted to we can build anything.
Also may I suggest something please this wing looks too heavy perhaps lighter materials like foam and balsa wood can do the job.
If you fly this, you will add "Home Depot Coffin" to your accomplishments. Unfortunately, plywood (particularly home depot plywood) is NOT an acceptable spar material. Also, joints in plywood spars cannot be made with sheet metal screw and gusset plates. I love a lot of your design creativity - but check with an EAA technical counselor or an A&P mechanic before you try and fly. Home depot aluminum won't work, either, as it is 1100, and good aircraft are made from 6061 T6 or 2024 T3.
this thing will collapse 25 feet off the runway,, so it is a joke and needs to be put in the archives of youtube fun,,,,,,so dont take seriously any of the aircraft parts of this video, unless you have a serious death wish, and loooooots of free time!
this guy is great, i want to see more of this project.everything is reinforced similar to his shed.i see where his construction ideas come from.i am sure the twist problem can be solved with 1/8 inch aluminum skin.it may be a tad under powered, check with nasa for a surplus engine.
There's a reason aircraft parts are so expensive: reliability. While I think its brilliant what you've come up with so far, its also very foolish to trust your life to untested parts. If something breaks at 5,000 feet, or much worse, 100 ft, what are you going to do? If you really want to do this I highly suggest installing an ultra-light parachute for emergencies. Its also highly advisable to look into FAA regulations regarding home-built aircraft...
Good thing as it will only be powered by a 25hp engine, your ass is already saved! Let me be squarely honest "Do studies first and don't play engineer"! If you want to be killed by stupidity through ignorance then it's your call but the chances of killing other people is not remote.
Why must one build cheaply on the expense of safety or life for this matter?
I would hate to see you injured!..please feel free to ask me any questions you would like as i would be more than willing to help!!!...also i have a great friend who is an aviation maint hall of famer at my imidiate disposal ...neil pobanz...look him up...thank you and godspeed!
also i would recommend using an aviation grade plywood spar with 1/8 inch thick plate aluminum strips on either side of the plywood spar then bond them together using strong adhesives and either aviation rivets or AN-3 or AN-4 bolts with large fender washers......the wing is the most important part please do a ton of research and if possible use a proven design and make your fuse work with it...just a few thoughts...i have built many aircraft and restored 25 warbirds.
you are gonna be too heavy for the power plant you intend on using...try using 1 inch thick foam for wing ribs...installed correctly they will serve there purpose ... which is to hold the form of your airfoil...with some other load factors...but thin plywood leading edge that reaches to the forward wing spar would be fine...then use dacron fabric or a composite to cover rest...again i stress strong construction and light weight.
I think maybe you should put it on pontoons and at least test it over water first. It does appear a bit heavy, but worse things have flown. Just think about your life because many people do get killed. The pilots that live a long time listen a lot, learn a lot, and they didn't get old by coincidence.
Dan - we applaud your ingenuity and desire for flight, but you should really do a couple of things: Join your local Experimental Aircraft Assocation (EAA) chapter.

If this is a left wing of an aircraft, when you move the aileron downward wouldn't it make the aircraft turn right instead of a left turn? Or am I missing on something here?
Is this going to be a remote control plane? If you are cosidering building this plane as a actual manned aircraft it would have to be built much much stronger or you will probably be calling Home Depot from the crash site.
@fendertelecaster8225 You are wrong there are plenty of planes built on less. In fact a friend of mine has a real airplane called a sky pup... the wings are made out of fabric covered styrofoam. The pink insulation styrofoam.. I know what your thinking... let me know how long he lives... well he has been flying it for 15 years now at least once a month even in the winter.
@buzzy1147 I really hope you are right and truthfully my concern was for the saftey of the home depot plane project. I actually hope it is a success , We will know when the project is completed and he makes some videos of the plane actually flying whether it was sturdy enough or not so only time will tell.
this "joystick gimbal" is just horrible. 2,44 it should be placed into aluminium holder. Not two tiny pieces of playwood not eaven attached together on top. In the air there will be a lot of force working at this part.
@SierzantYelonek Seriously dude, that is where the fuselage will be, i'm sure there will be more to it.. you can't look at something that isn't finished and jump to conclusions.
The hinge on the aileron should be bolted not screwed on. the wing you showed could easily weigh pass 150 lbs when covered with aluminum skin. Double that for the whole wing would be 300 lbs.plus fuselage with seat, wheels and instrumentation which could weigh at least 150 lbs plus the tail section add another 100 lbs all adds up to at least 700 lbs. Propeller efficiency is only 70% at best. you would be lucky if you get 50 kph stalling speed. YOU WILL NEED A MORE POWERFUL ENGINE.
Looking at your project again.. how is it coming along? Any updates? I am wondering why people say your joystick gimbal needs a rethink. Thats my favorite part of your wing I really like it. I agree with the naysayers that your ribs are huge though. Do you have any full size airplane plans to refer to at all?
I sincerely hope the wings will fold up or simply collapse under their own weight before you get more than 2 ft off the ground. If it rises more than 50 ft, it will kill you. I wanted to design and build my own airplane since I was 14. The difference is , I knew what I didn't know and what i had to learn. You cannot design and build something like this on the basis, of "Oh, that looks about right...." Join a local EAA chapter and get some eduction, please!
You should first get the nuances of model plane building that cost lest if you fail. You have a very long way to go but nonetheless i wish you success and satisfaction. A lot of my friends says that you are bound to fail. I told them that you are better equipped than 2 bicycle mechanic named wilbur and orville. good luck buddy.
joined them incorrectly, 2nd, plywood is not the right material to use, third,the dimension is not suited for its intended job, fourth, the alignment is meant for rigidity so that the wing has no other way to go but twist when force is applied.The wing must be strong but flexible in the right direction which is upward. please see Boeing 787 wing break test - YouTube. I would advice you to make a smaller model plane since what you have started would definitely end in catastrophic failure.
your airfoil rib would have better capability if you us NACA 4412 profile. You must first know the basics like type of materials to use and its weight so you can get its center of gravity which is the most critical aspect in safe flying. Your ribs are broken in 2 parts and screwed to the spar like you do on cabinets and shelving which is okay if applied to a static structure,but a plane is a dynamic structure. Your spar is wrong in many ways, first it has an inherent weakness for you have....
Your workmanship looks pretty good, but that spar is going to break, and you can't put sheet metal over wood wings! You need fabric instead. And there is no way 20-25hp will get that off the ground with any human in it, or as heavy as it looks so far. I suggest you pick up an AC 43.13, the A&P's bible to learn about acceptable materials and practices.
I really give you the credit, all the hard work and careful consideration to detail yet remaining within budget, its just amazing. So are you ready to die?
Well I just almost couldn't quit laughing, make a coffee table out of this it will be much safer.
Fallowing your thinking, I took a bath this morning so I should be able to swim the English channel and I climbed out of bed this morning so I should be able to conquer Mt Everest. You know what that means, I'm going to see the Swiss Alps and Great Brittan WHOA HOE I'm outta here!!!
I liked all the project but the plane. I think the airfoil is wrong for a slow flyer, should have been thicker and longer. Perhaps a RC plane but no way I would try to fly this myself.
+100 for enthusiasm. -1000 for inadequate research. If you're going to do a monocoque wing with the load on the skin, buy several sheets of the home depot 2" blue insulating foam, wirecut desired airfoil and cover with fiberglass. Do a lot of research on Rutan. Then go from there... I'm thinking of recreating a "Woodhopper" in composites.... Your work looks better than average, but it's still dangerous -- every hole is a stress point you better know where/why to drill 'em, and what size.
@ruxpin76 having run a lumber company that dealt with every known import and domestic plywood known to man , i can tell you that there is no such thing as "aircraft grade plywood"
anyone that sells it as such is is simply jacking up the price by putting a label on wood that
anyone can get and sell . if it says " aircraft grade " someone is BS ing you
@steelguitarplayer1 - I am a licensed A&P, licensed flight instructor, licensed aircraft inspector, and University Degreed Physicist. I have built real aircraft. There is aircraft grade plywood, and it IS DIFFERENT.
I've always wanted to build my own plane...kudos to you for actually moving on your dream. After giving it much thought, I figured my wallet would handle balsa wood models better than the real thing, and if I were to build a real plane, it'd have to be from a kit, with everything planned out and parts which were made for the purpose. 100 AGL is a very unforgiving environment.
man!!!....i do give you major points for enthusiasm with that plane!!!...but seriously - stick to the boat you have out the back!!.....that one seems to be tried and tested at least.........good luck
It sounds like you're relying on the wing covering for strength. This is where the spar comes in. Seriously, I would just put a 200 lb. dead weight in the pilot's seat and launch it off a catapult.
WOW! That's one of the scariest things I've ever seen. While all the reinforcements might be good on a wooden boat, it makes it impractical and very heavy for a light aircraft. Even if you ever get it of the ground with your lawnmower engine, I hope you're in the middle of the desert and your life insurance is paid up to date. There are so many resources of information in this field, there's no need to make up crap. You would be safer with the Wright brothers design. Make a boat instead.
@SSGPops the other funny thing about this is that he said the opposite turns for the direction of the ailieron he said its the left wing when the aileron down he said it would turn left ha no it will turn right
@brice1157 Well, it's obvious he doesn't even have the basics of flying. Any semi-decent flying school would have answered many of his misconceptions on day 1. While it's OK to dream and roll up sleeves up on a project, any project that can be life threatening is owed at least a minimal amount of research if one wants to show any kind of respect for the subject matter. Given enough engines and balls any spruce goose can take off a few feet of the ground. Landing is another matter.
I would never get in that thing even if it did fly. Im sorry but that looks like it could be a death trap. You have innovative solutions but this is not an area where you try stuff like that. You want proven designees and you want to exceed the regulations. get some help from someone who has experience building aircraft. Im a student learning about aeronautics and this just doesn't look like a good idea. is that just one part of the wing? if it isn't you better have one incredible engine.
i never built an airplane that carried a person...but i built a lot of rc planes...my concern is this,,,your gimbal for ailerons is supported by plywood on the sides..my opinion that is not strong enough..also the rods going through the wings to control the ailerons, those cannot flex while under operational stress(wind pushing back on the aileron) i think supports on those to keep them from flexing would be important. aluminum skins on the wings still may be too hvy for the structure you have.
What great fun. But why re-invent the wheel? As a builder of multiple aircraft I cannot see a single detail on your project which would meet anyones standard of minimums for a flyable aircraft meant to carry a human passenger. Get help, and I don't mean that in the mental illness way. To avoid litigation you might want to announce that you are joking.
cool ! hows d proyect going? wheight should b ur primary concern so changing control mechanisim to a pulley nd cable config its a good idea nd have u consider wraping it w/ fabric its lighter, cheaper nd way easier. also a lill twisting nd bending on d wing its necesary a structure to riggid will b ripped of d fuselage w/ d air pressure nd or @ landing u need dat flexing.. great proyect ! have fun..
Having built three airplanes (from plans), I would suggest you go that route - in my humble opinion. ALL of the comments, presented here on, are absolutely correct! It has NO drag spars; has NO compression spars; no gussetts; no doubler plates, no blocking, etc., etc, etc. We are just trying to be helpful, and not critical. It's a good start, but definitely a "non starter" airplane. N-6395T
Holy Cow, this is ambitious. I agree with the other commenters. You should join EAA, and get plans for a Volksplane. Its similar size to what you have there, but it's a proven design. There are a number of fatal flaws in the structure you have there.
Dan, have you heard of the Experimental Aircraft Association? eaa.org. They have a TON of resources for the homebuilder and experimental aviator. Get in touch with them - it could save your life. Literally. My advice is to very carefully hang that wing up on the wall, and get hold of a set of plans for a proven design.
'Ignore thou not the laws of physics, oh birdman, lest the Earth rise up and smite thee!' - The Gospel According to Orville, Chapter 1, Verse 1
@austdata not to mention lack of diagonal drag rigging to prevent twist, pitot tube that appears to have no static ports, the wings look WAY too short to lift this beast, ribs are few and far between, etc.
Perhaps a 1/2 scale R/C model of it would be prudent as a first step towards building your own home depot plane. I hope he doesn't fly it...lost too many friends doing things like this.
as far as control mechanisms, assemble them out of the wing and form a straight line with the cables, nuts/bolts, rods, etc. attach each end one on the back bumper of one car/truck and the other to another car/truck and have one other person to drive in the opposite direction, if the mechanism snaps apart, you'll have to redesign the linkages until it is strong enough to withstand the tug of two cars/truck driving in opposite directions.
It might also help to get up ontop of the center of the wing and hop up and down vigorously and stomp on it to simulate turbulent weather. Durability and strength of Wing, connection to control surfaces, and mechanical linkages is critical. It might be best to build the first prototype just for stress testing purposes, once it passes then rebuild or improve each component depending on the initial stress tests
once you build your wing, make sure you get a bunch of sandbags 6X the weight of what you think the plane is going to be, place two strong stands under each end of the wing, and put the sandbags on the wing, flip wing over and repeat process again, if your wing breaks, bends, or folds, it's not airworthy enough to withstand 6 +/- G's which is a minimum standard for most small aircraft.
Sir you should look into composites, very strong and lightweight material, much safer for building aircraft parts, or using aluminum frames since metal is more flexible and doesn't have risk of snapping apart like wood
i know, this is one of those flu-tag things where you roll it off a ramp into water. i hope your sitting on top the wing and not underneath it. why dont you build a boat instead.
This is scary. You use ordinary plywood for the ribs when you should use aileron grade plywood. You moved the aileron down on the left wing and you said the plane would turn left - actually, it will turn right. Using the aluminum is good but you should incorporate some ribs to form some triangles. If you have built model airplanes before, you will know what I mean. I won't even attempt to fly this.
Oh yes, the gymbal for the stick would be ripped out at the least load on the elevator, because it is hanging out on two very questionable pieces of wood that create an arm moment forward of the spar.THIS Whole project is DANGEROUS just to be on youtube, because someone might take it seriously and copy you and get hurt or worse killed!! BONFIRE TONIGHT, ANYONE??
If the rest of the airplane is built like what i saw here then it is going to be an incerdibly HEAVY airplane with the structural integrity of wet spaghetti!!! THE VIDEO IS OK , BUT LEARN MORE ON AIRCRAFT STRUCTURE,,,FOR YOUR OWN SAFETY, PLEASE?
well you have a shear web thats got no spars. what is it exactly? its not a shear web beam...not a box beam....not even a beam and it has a split which should have a scarf joint IF it were really a beam and thats not even an airfoil or a leading edge. where are the diagonal braces and compression braces? that leading edge will stall on takeoff. center of lift is too far back and you only have 1 beam.you need 2 beams. that thing is so heavy you need 150mph to get off the ground. you need plans.
Jesus! is not even a complete spar it has a split right in the middle. I hope; for you own safety, you won´t go further with this project, I can see that you have craftmanship, but you are designing the wing very wrong. you are actually using not cheap materials, but instead NOT the right ones. Contact you local EAA and they will be very happy to help you with your project.
While I have the greatest enthusiasm and respect for aviation and those who apply themselves toward crafting something, unless you have a death wish, don't even think of being on board that thing while it's moving!
As an RC plane, it might be amusing as long as you expect little more than catastrophic results. ;)
For the love of your life and the piece of mind of all of us, douse that thing in gas and burn it. Your spar is poorly designed and even more poorly made. Since it has no cap strips it will fail. There are no drag/anti drag wires. Your plywood is of poor quality. The hardware is dangerous looking. If this thing is allowed to take off and it kills or maims someone or their property on the ground you will be held liable!
I do like your aileron control. What rib numbers did you go with? a thin airfoil like that requires a fast airspeed.. unless it is much longer. The only way she will fly is if you have extreme horsepower but with your design the internal structure won't handle it. The other issue is drag and anti drag as in compression structure. It's nice to see someone working on their dream but there is a reason for 2 spars.
@buzzypeterson1147 The thickest part of the wing is 5.75 and its pushed back toward to the spare. This will probably wind up as very big RC plane for use in autonomous flight experiments. It has 6 ribs and is calculated to generate over 900 lbs of lift for 2 wings.
It looks really heavy.. would it ever get off the ground with heavy electric light boxes and such materials?

You must first know the basics like type of materials to use and its weight so you can get its center of gravity which is the most critical aspect in safe flying. Your ribs are broken in 2 parts and screwed to the spar like you do on cabinets and shelving which is okay if applied to a static structure,but a plane is a dynamic structure. Your spar is wrong in many ways, first it has an inherent weakness for you have....

Your workmanship looks pretty good, but that spar is going to break, and you can't put sheet metal over wood wings! You need fabric instead. And there is no way 20-25hp will get that off the ground with any human in it, or as heavy as it looks so far. I suggest you pick up an AC 43.13, the A&P's bible to learn about acceptable materials and practices.

+100 for enthusiasm. -1000 for inadequate research. If you're going to do a monocoque wing with the load on the skin, buy several sheets of the home depot 2" blue insulating foam, wirecut desired airfoil and cover with fiberglass. Do a lot of research on Rutan. Then go from there... I'm thinking of recreating a "Woodhopper" in composites.... Your work looks better than average, but it's still dangerous -- every hole is a stress point you better know where/why to drill 'em, and what size.

I've always wanted to build my own plane...kudos to you for actually moving on your dream. After giving it much thought, I figured my wallet would handle balsa wood models better than the real thing, and if I were to build a real plane, it'd have to be from a kit, with everything planned out and parts which were made for the purpose. 100 AGL is a very unforgiving environment.

WOW! That's one of the scariest things I've ever seen. While all the reinforcements might be good on a wooden boat, it makes it impractical and very heavy for a light aircraft. Even if you ever get it of the ground with your lawnmower engine, I hope you're in the middle of the desert and your life insurance is paid up to date. There are so many resources of information in this field, there's no need to make up crap. You would be safer with the Wright brothers design. Make a boat instead.

@SSGPops the other funny thing about this is that he said the opposite turns for the direction of the ailieron he said its the left wing when the aileron down he said it would turn left ha no it will turn right
brice1157 3 weeks ago
@brice1157 Well, it's obvious he doesn't even have the basics of flying. Any semi-decent flying school would have answered many of his misconceptions on day 1. While it's OK to dream and roll up sleeves up on a project, any project that can be life threatening is owed at least a minimal amount of research if one wants to show any kind of respect for the subject matter. Given enough engines and balls any spruce goose can take off a few feet of the ground. Landing is another matter.

I would never get in that thing even if it did fly. Im sorry but that looks like it could be a death trap. You have innovative solutions but this is not an area where you try stuff like that. You want proven designees and you want to exceed the regulations. get some help from someone who has experience building aircraft. Im a student learning about aeronautics and this just doesn't look like a good idea. is that just one part of the wing? if it isn't you better have one incredible engine.

i never built an airplane that carried a person...but i built a lot of rc planes...my concern is this,,,your gimbal for ailerons is supported by plywood on the sides..my opinion that is not strong enough..also the rods going through the wings to control the ailerons, those cannot flex while under operational stress(wind pushing back on the aileron) i think supports on those to keep them from flexing would be important. aluminum skins on the wings still may be too hvy for the structure you have.

As a builder of multiple aircraft I cannot see a single detail on your project which would meet anyones standard of minimums for a flyable aircraft meant to carry a human passenger. Get help, and I don't mean that in the mental illness way. To avoid litigation you might want to announce that you are joking.

Having built three airplanes (from plans), I would suggest you go that route - in my humble opinion. ALL of the comments, presented here on, are absolutely correct! It has NO drag spars; has NO compression spars; no gussetts; no doubler plates, no blocking, etc., etc, etc. We are just trying to be helpful, and not critical. It's a good start, but definitely a "non starter" airplane. N-6395T

Dan, have you heard of the Experimental Aircraft Association? eaa.org. They have a TON of resources for the homebuilder and experimental aviator. Get in touch with them - it could save your life. Literally. My advice is to very carefully hang that wing up on the wall, and get hold of a set of plans for a proven design.

CorrieBergeron 3 months ago
I applaud your enthusiasm but feel compelled to add a caution.
1) The spar should be one piece. It will very likely fail at the join under slight load
2) The ribs are too thick, therefore too heavy
3) The leading edge strip is too big, too heavy
Pushrod controls are okay, but
4) No fail-safe when the aileron pushrod bends and it will
5) No fail-safe if pushrods detach
6) Locating & fixing points appear to be inadequate for flying load.
7) The "joystick gimbal" needs rethink
Good luck

@austdata not to mention lack of diagonal drag rigging to prevent twist, pitot tube that appears to have no static ports, the wings look WAY too short to lift this beast, ribs are few and far between, etc.
Perhaps a 1/2 scale R/C model of it would be prudent as a first step towards building your own home depot plane. I hope he doesn't fly it...lost too many friends doing things like this.

winnmicro 3 months ago
as far as control mechanisms, assemble them out of the wing and form a straight line with the cables, nuts/bolts, rods, etc. attach each end one on the back bumper of one car/truck and the other to another car/truck and have one other person to drive in the opposite direction, if the mechanism snaps apart, you'll have to redesign the linkages until it is strong enough to withstand the tug of two cars/truck driving in opposite directions.
EasternMerchant 3 months ago
It might also help to get up ontop of the center of the wing and hop up and down vigorously and stomp on it to simulate turbulent weather. Durability and strength of Wing, connection to control surfaces, and mechanical linkages is critical. It might be best to build the first prototype just for stress testing purposes, once it passes then rebuild or improve each component depending on the initial stress tests
EasternMerchant 3 months ago
once you build your wing, make sure you get a bunch of sandbags 6X the weight of what you think the plane is going to be, place two strong stands under each end of the wing, and put the sandbags on the wing, flip wing over and repeat process again, if your wing breaks, bends, or folds, it's not airworthy enough to withstand 6 +/- G's which is a minimum standard for most small aircraft.

Sir you should look into composites, very strong and lightweight material, much safer for building aircraft parts, or using aluminum frames since metal is more flexible and doesn't have risk of snapping apart like wood

i know, this is one of those flu-tag things where you roll it off a ramp into water. i hope your sitting on top the wing and not underneath it. why dont you build a boat instead.
datzfast 3 months ago
This is scary. You use ordinary plywood for the ribs when you should use aileron grade plywood. You moved the aileron down on the left wing and you said the plane would turn left - actually, it will turn right. Using the aluminum is good but you should incorporate some ribs to form some triangles. If you have built model airplanes before, you will know what I mean. I won't even attempt to fly this.

well you have a shear web thats got no spars. what is it exactly? its not a shear web beam...not a box beam....not even a beam and it has a split which should have a scarf joint IF it were really a beam and thats not even an airfoil or a leading edge. where are the diagonal braces and compression braces? that leading edge will stall on takeoff. center of lift is too far back and you only have 1 beam.you need 2 beams. that thing is so heavy you need 150mph to get off the ground. you need plans.

For the love of your life and the piece of mind of all of us, douse that thing in gas and burn it. Your spar is poorly designed and even more poorly made. Since it has no cap strips it will fail. There are no drag/anti drag wires. Your plywood is of poor quality. The hardware is dangerous looking. If this thing is allowed to take off and it kills or maims someone or their property on the ground you will be held liable!

That wing spar should be a boxed spar instead of a solid wing spar. The wing has to have two compression struts. Be careful and don't kill your self.
gpzbilly 9 months ago
I do like your aileron control. What rib numbers did you go with? a thin airfoil like that requires a fast airspeed.. unless it is much longer. The only way she will fly is if you have extreme horsepower but with your design the internal structure won't handle it. The other issue is drag and anti drag as in compression structure. It's nice to see someone working on their dream but there is a reason for 2 spars.
buzzypeterson1147 11 months ago
@buzzypeterson1147 The thickest part of the wing is 5.75 and its pushed back toward to the spare. This will probably wind up as very big RC plane for use in autonomous flight experiments. It has 6 ribs and is calculated to generate over 900 lbs of lift for 2 wings.
