@@SSGTWinters This design is made for electric propulsion only. If you want to convert this into a gas powered UAV, you have to think about enlarging internal area's for fuel storage and other components (instruments) that go with it. But the most complicated thing would be the weight by the gas engine itself, and all the combined weight by the reinforcements needed throughout the airframe to prevent fatigue by the engine vibrations. My advice is to keep it electric but upgrade to a powerful electric engine that has the same CC-output/or equivalent as a gas engine.

For these flying machines, I'd be cutting plastic, maybe the foam that is shown in the video, 1/16" and 1/8" plywood, or carbon fiber. Here is a clock that I made of wood, aluminum and carbon fiber.

Really enjoyed the build, but a helpful comment....the duct tape will add a TON of weight. Something like a colored straping tape or packing tape will add the rigidity you are looking for while not adding an abundance of weight.
Great work Aero! I am currently making a duplicate right now. I will keep you up with my progress. If there a request, I would like to see how you program INav or other to fly waypoint missions. Thanks so much!
Outstanding design and craftsmanship. Matter-of-fact when I first saw your video promo in my recommendations, I clicked on it looking for a link to buy it.

The correct foam and plans, for convenience because for some people, sourcing the right Depron etc. can be a hassle.
A step beyond the single pusher would be a twin tractor, in terms of efficiency, range and weight carrying capacity. you also have other benefits, such as no torque, slipstream effect, P factor, gyroscopic precession, easy to eliminate power/pitch coupling, payload is protected from vibration, still a good view from the front of the aircraft for sensors, better mass distribution, larger disk area, etc. also tractors have less vibration due to clean air going in the prop arc, and have more room in the fuselage, as well as less twisting of the wings by the booms. many many advantages. this looks very well built, and looks great in the air. how are you getting the air to air shots?
Thank You! Totally agreed on the advantages compared to this configuration - I didn't even know they were so many besides noise, vibration torque and carrying capacity. I'm flying a DJI Mini 2 while the aircraft does it's WP-Missions
Twin tractor, you mean two engines on the wing pulling rather than pushing? basically every twin recip Cessna yes? I know twins are safer in case of engine failure, which also means nothing when you run out of batter, but, I'm wondering about efficiency. is that because you have more excess power for the weight? since you are not doubling the servo/controller/infrastructure weight? since you still need the motor and battery 2x. More things to break? what bout the pusher puller concept? single slip stream? you also mentioned that the forward propellor would have better air to bite into, but, then the wings have bumpier air.. I didn't know there was a benefit there.. in that case, it would be better to have 2 pushers on each wing and get the best of both worlds no? like a jet engine would. Thoughts???
@@gjsxnobody7534 more disk area means less pressure difference for a given amount of thrust. efficiency is improved. yes, you are correct about the definition of twin tractor. yes, there is some disturbance of the airflow over the wing, but it is almost all straight by the time that the air reaches the wing if the nacelle is long enough, as they usually are. in the case of an inline twin, the air is accelerated twice in the same stream, which decreases efficiency, when compared to a twin tractor. it is good for very high speed aircraft, and still flies well with one engine out, in the case of fuel powered manned aircraft, but not very great for long distance flying, with the rare exception of Voyager. This worked because of the very long distance between the tractor, and pusher, and also that the pusher was shut down partway into the flight, and prop feathered. prop on back of wing Trailing edge would cause intense vibration due to pressure differential of the wing hitting the prop arc. it has been tried, and can work, but not desirable in most cases, and not that efficient. it is undesirable for the accelerated air from the props to hit anything that is not necessary, with the exception of the wing. yes, there is some bad airflow, and some loss, but there are several benefits. most of the aero drag from the accelerated air hitting the wing is recuperated in lift. the increase in lift allows the aircraft to fly slower, reducing overall drag. and mounting the motors to nacelles on the leading edge of the wing, right to the main spar saves structural mass compared to mounting them literally anywehre else. it also allows for 2, 4, 6, etc. motor configurations, and reduces takeoff distance significantly, as well as lift at any high power setting. it is counter intuitive that more motors and props is more efficient, not less. and that is only true if the motors/props are efficient themselves, and do not have a. large aerodynamic penalty in drag from each nacelle. more motors will make a draggy, inefficient design worse, but will make a good one better. make sense? don't take my word for it. look up distributed electric propulsion. most configurations use a blown wing, although there are other possibilities.

Hi Aerostuff. Excellent very detailed and well presented build. Happy to be a new subscriber. As a newbie to UAV I have a lot of your builds to look through. Thanks.
An absolutely smashing aircraft. I wanted to pursue something similar myself but once the UK locked down flight rules for aircraft like this I abandoned the idea. Still, thoroughly enjoyed watching your craft take flight. Thank you.
Hi you might take a look at a plane design we used to build back in the day, it was called a “ Ben buckle” it only had rudder and elevators but could be modified to have ailerons , I built one of these about 10 years ago it was so efficient it took me ages to get it down
Thanks! It’s a belly-lander (just lands on the reinforced fuselage - The propeller doesn’t break off because the ESC has a ‘brake’ which stops the propeller from spinning by the wind
Great looking and flying UAV. Watch the opening 2.5 minute flying sequence and maiden flight portions of the video a few time. Amazing aerial video work to capture its majestic beauty in flight.
I'm curious on your prop size, spar size (length and width), and how you attached your spar/wings. I've created a similar plane, but mine doesn't fly nearly as good as yours. Thanks and great work!
I second this question. I'm doing my first removable wing build but am having trouble getting them to line up an secure them in place with too much over engineering which adds too much weight.
That's the part I accidentally left out (but is mentioned in the flight video) The spar (aluminium 1000x10x10) is put through the middle wing and the side-wings are connected with that spar as well - To secure them in place, I simply put tape between the two wing-edges and that' all it needs. Note that the spar is square so that the outer-wings can't rotate by any force of ailerons or wind, which is more likely with a round spar
@@droomdronen731Hobbyking or AliExpress! Just search for “14 inch propeller” or 14x4.7 If you can’t find it, other props (dependable on your motor) will also work. I now have a 12x6 which is more efficient than the thick 14-inch carbon SlowFly
Excellent job, and very interesting! One point I may have missed. How did the outer wings were attached to the inner wings? I am assuming you used the square aluminum for a spar and support for the outer wings. Please correct me if I'm wrong. Thank you for your efforts.
Thanks man! Great you've discovered the part I left out - The spar (aluminium 1000x10x10) is put through the middle wing and the side-wings are connected with that spar as well - To secure them in place, I simply put tape between the two wing-edges.
@@AeroStuffFPV, Thank your for the nice tutotrial! 1. Is it possible to use carbon square as booms? 2. Is it possible to use carbon square to connect outter wings too? 3. How cruical weight distribution? 4. Should I put plastic card under the tape in the middle wing? Thank you in advance!
WOW This is incredible, I love this shape for planes! I tried making something similar but made the mistake of using wood for the frame and eyeballing the 90º angles, the poor thing couldn't stay level for more than 10 or so meters. Perhaps I'll ~~get inspiration from~~ (completely copy) your design this summer. Thanks a lot for posting this!
Quick follow up question, if I may, how did you join the outer wing sections to the inner one? If I somehow missed it in the video let me know, but I can't find it. Thanks in advance!
Launching it (with a 14x4.7) is the closest call without hitting fingers - Side/Swing launch is optional But I’m replacing the 14” with a 12x6 for better efficiency and less risk of a prop strike
Congratulations on hitting the algorithm! I suspect you're pulling in the vaugely-tactical hobbyist crowd. I've never made anything like this but I want to now. seems pretty affordable, and not overly complicated. Do you have another build you'd recommend starting with or is this a good one to start with?
Thanks! It really isn’t expensive or complicated- This is my easiest way to build something close to an expensive one regarding capabilities & applications I have other build-videos which are easier to build (V-Tail Pusher) - Or go to Experimental Airlines for just the basic way of building an RC plane
Really cool man, thanks for making these. Its inspiring. Is prop noise a significant factor for you? I'm pretty new to all this and my understanding is that tractor is quietest because cleaner airflow hitting the prop. Have you found that to be true in practice? If that is the case, would middle prop be the loudest?
Thanks man! You're right. Tractors are the most quit of all other configurations because like you said, there is no turbulent 'wash' coming for the prop. This is very noticeable with my FPV Planes as the tractors are very quiet (you can see them fly-by on my channel after Long-Range FPV moments with cetrain models), compared to the pushers like my V-Tail builds or a Flying Wing design featured on my channel (which is the loudest FPV platform I ever built) - You literally could hear it buzz at over 800m away at +300ft up... With this particular design, the propeller isn't that close to the trailing edge of the middle wing so the noise isn't that loud - But the characteristic pusher noise is always present. This also depends on the type of propellers (slowfly, carbon or direct-drive props)
Great videos. Can you create a video for beginners? I am trying to build my son's first FPV plane. We do not have any experience with FPV. So links on what to buy and how to setup would be great. Also, he wants to see Video too.. you know trying to get him off the video games and into real life. Thanks
Really cool design, I'm a huge fan of these types of projects on RUclips and I'm thinking of starting my first of my own. Can anybody recommend a video talking about all the required electronics?
a really nice build, but I personally think that the structure would be sturdier if you used 5 or 10 min 2part epoxt to glue down the most structural part, like the booms, and the motor, elseway, thanks a lot to share the project, it makes me want to make one myself
Maybe, but it really doesn't matter. hot glue is plenty strong enough. I've built and crashed dozens of planes like this, and usually the foam rips and tears long before the hot glue fails. epoxy would give you a slight weight advantage, but the savings would be negligible on a craft with such a massive carrying capacity. epoxy just complicates the build due to its cost, cure time, workable time after mixing, and clean up.
Very informative. May I suggest a beginner airplane with detailed diagrams and parts etc. Also maybe a video on support products you use like inav etc. I'd like to build something
Always wondered if it's legal or so to make one of these capable of flying across a state and using something like cellular transmitting to control it Like if you had a whole bunch of solar panels on the wings, decent batteries, and efficient motors it could stay in the air for countless hours, especially if you ride thermals to get lift
Brilliant video and awesome flying plane! I wonder what you used to film your aircraft in flight? That is some great flying footage! The aircraft felt much larger in the flight video. I am surprised that it is so compact!
Thanks! It’s 1.6m in wingspan but can be customized to fit larger outer-wings to increase the wingspan I flew a DJI Mini 2 while the plane did WP Missions.
@@v0id683 aluminum spars at angles to deflect radar signatures, engine cowls to reduce any radar signatures that could be picked up from the engines, low reflectivity materials such as fiberglass, carbon fibre, high density foam. Oh and don’t forget the blended wing body which increases its range!
Congratulations, this is really cool, unfortunately not allowed in Germany. The Pilot must be always able to see his plane 😭 Also, pure FPV is for the Pilot not allowed 😢
Wow, good video. Put together with a glue gun and foam board. I guess a bigger gust of wind will just blow it out of the sky, but well for the budget simple build, this looks to be working pretty good.
Really cool design. Would love to see a solar panel. And a straight line way point mission beating public transport. Can deliver letters from your home address to your collage. Just an idea.
Been waiting for that my entire career! Because then I can have that particular drone record TWO of my planes at the same time, close proximity in a Two-Ship formation. (One flying autonomous and the other in control)

Hi you might take a look at a plane design we used to build back in the day, it was called a “ Ben buckle” it only had rudder and elevators but could be modified to have ailerons , I built one of these about 10 years ago it was so efficient it took me ages to get it down
You are smart. Made me watch 16 of your videos to see how to hook the wings on.
Great engineering!!! I was just wondering how did you manage to land it? Thanks
Thanks! It’s a belly-lander (just lands on the reinforced fuselage - The propeller doesn’t break off because the ESC has a ‘brake’ which stops the propeller from spinning by the wind
Beautiful build and it looks smooth as butter in flight.
Great looking and flying UAV. Watch the opening 2.5 minute flying sequence and maiden flight portions of the video a few time. Amazing aerial video work to capture its majestic beauty in flight.
That thing looks sick, once I get some serious free time I gotta work on something myself
Very nice! I've been wanting to build a plane in this configuration for awhile. Might have to copy yours.
Go for it!
Best flying footage ever👌🏾👌🏾👌🏾👌🏾 Really Dope
I'm curious on your prop size, spar size (length and width), and how you attached your spar/wings. I've created a similar plane, but mine doesn't fly nearly as good as yours. Thanks and great work!
I second this question. I'm doing my first removable wing build but am having trouble getting them to line up an secure them in place with too much over engineering which adds too much weight.
That's the part I accidentally left out (but is mentioned in the flight video)
The spar (aluminium 1000x10x10) is put through the middle wing and the side-wings are connected with that spar as well - To secure them in place, I simply put tape between the two wing-edges and that' all it needs.
Note that the spar is square so that the outer-wings can't rotate by any force of ailerons or wind, which is more likely with a round spar
14x4.7 Propeller
@@AeroStuffFPV could you link that prop because I can't find a 14*4.7 prop anywhere
@@droomdronen731Hobbyking or AliExpress! Just search for “14 inch propeller” or 14x4.7
If you can’t find it, other props (dependable on your motor) will also work.
I now have a 12x6 which is more efficient than the thick 14-inch carbon SlowFly
I love that project nice work 👍👍👍
You have some amazing air-to-air videography, what are you using for that?
Thanks man, DJI Mini 2!
thanks for your INSPIRING WORK, PLEASE CONTINUE !!!, my apology, no support, i am a retired person...nochmal DANKE DANKE DANKE !!!
Great work, outstanding.
Just found my new favorite channel.
Excellent job, and very interesting! One point I may have missed. How did the outer wings were attached to the inner wings? I am assuming you used the square aluminum for a spar and support for the outer wings. Please correct me if I'm wrong. Thank you for your efforts.
Thanks man!
Great you've discovered the part I left out - The spar (aluminium 1000x10x10) is put through the middle wing and the side-wings are connected with that spar as well - To secure them in place, I simply put tape between the two wing-edges.
@@AeroStuffFPV, Thank your for the nice tutotrial!
1. Is it possible to use carbon square as booms?
2. Is it possible to use carbon square to connect outter wings too?
3. How cruical weight distribution?
4. Should I put plastic card under the tape in the middle wing?
Thank you in advance!
This is exactly what I’ve wanted to do for a long time
WOW This is incredible, I love this shape for planes!
I tried making something similar but made the mistake of using wood for the frame and eyeballing the 90º angles, the poor thing couldn't stay level for more than 10 or so meters.
Perhaps I'll ~~get inspiration from~~ (completely copy) your design this summer. Thanks a lot for posting this!
Quick follow up question, if I may, how did you join the outer wing sections to the inner one? If I somehow missed it in the video let me know, but I can't find it. Thanks in advance!
Thanks, good luck!
In the next video, I’m showing you the setup - I join the wings together with the spar and tape the edges so they won’t slide out
I'm nostalgic now, I heard the music from a very old Ramy RC video. Thanks for the interesting video!
In case you're wondering, the song is "Neon Underworld" by Punch Deck
Great video, thanks for sharing. How do you launch something like this without loosing fingers or a hand? Can you put up a launch video as well?
Launching it (with a 14x4.7) is the closest call without hitting fingers - Side/Swing launch is optional
But I’m replacing the 14” with a 12x6 for better efficiency and less risk of a prop strike
Awesome work Nathan!
Many Thanks!
This UAV reminds me a lot of the IAI Searcher II drone, maybe you should try your hand making a miniature version of this famous UAV.
Thanks for the video, definitely going to get into this..looks so fun!
Congratulations on hitting the algorithm! I suspect you're pulling in the vaugely-tactical hobbyist crowd. I've never made anything like this but I want to now. seems pretty affordable, and not overly complicated. Do you have another build you'd recommend starting with or is this a good one to start with?
Thanks! It really isn’t expensive or complicated- This is my easiest way to build something close to an expensive one regarding capabilities & applications
I have other build-videos which are easier to build (V-Tail Pusher) - Or go to Experimental Airlines for just the basic way of building an RC plane
You have a good eye for design. Nice job all around.
Thank you! Cheers!😎
This flight is also really good! How about attaching landing gear to an airplane?
It’s possible but it’s fine with landing on the fuselage
landing gear would add weight and drag which reduces efficiency and flight times
Brilliant again my friend it looks amazing. My third plane will be a carbon copy of yours keep going brilliant work and thanks ever so much. Pj
Looks really good. Well done. Question.....how do you land it without breaking or damaging the propeller?
Thanks! ESC has a brake function to stop the propeller from ‘windmilling’ and reduce the risk of a broken/damaged prop
Unbelievable info in just 13 mins. Wow
Beutiful build and flight. Great instruction. What are you using for the air to air videos? Mavic?
Thanks man! Using a Mini 2
cool - I would have so-loved all this tech when I was doing my RC aero stuff in the early 1970s
Really cool man, thanks for making these. Its inspiring.
Is prop noise a significant factor for you? I'm pretty new to all this and my understanding is that tractor is quietest because cleaner airflow hitting the prop. Have you found that to be true in practice? If that is the case, would middle prop be the loudest?
Thanks man!
You're right. Tractors are the most quit of all other configurations because like you said, there is no turbulent 'wash' coming for the prop.
This is very noticeable with my FPV Planes as the tractors are very quiet (you can see them fly-by on my channel after Long-Range FPV moments with cetrain models), compared to the pushers like my V-Tail builds or a Flying Wing design featured on my channel (which is the loudest FPV platform I ever built) - You literally could hear it buzz at over 800m away at +300ft up...
With this particular design, the propeller isn't that close to the trailing edge of the middle wing so the noise isn't that loud - But the characteristic pusher noise is always present. This also depends on the type of propellers (slowfly, carbon or direct-drive props)
Good design! Easy to build and power efficiency. Thanks for sharing.
Great videos. Can you create a video for beginners? I am trying to build my son's first FPV plane. We do not have any experience with FPV. So links on what to buy and how to setup would be great. Also, he wants to see Video too.. you know trying to get him off the video games and into real life. Thanks
I’ll get to that - Stay tuned
you could add some wheels down. very good build.
Not needed - It’s a belly-lander
Gorgeous plane! Are plans available?
Thanks!
No plans man.
You made that look trivial. Nice.
Great video! I'd like to see an autonomous targeting and preferably a kamikaze function on part 2 with a few kilogram payload if that's possible. :D 😆
Excellent build, Sir!
Thanks!😎
Really cool design, I'm a huge fan of these types of projects on RUclips and I'm thinking of starting my first of my own. Can anybody recommend a video talking about all the required electronics?
Really awesome project and share, thanks a lot 🙏
a really nice build, but I personally think that the structure would be sturdier if you used 5 or 10 min 2part epoxt to glue down the most structural part, like the booms, and the motor, elseway, thanks a lot to share the project, it makes me want to make one myself
Maybe, but it really doesn't matter. hot glue is plenty strong enough. I've built and crashed dozens of planes like this, and usually the foam rips and tears long before the hot glue fails. epoxy would give you a slight weight advantage, but the savings would be negligible on a craft with such a massive carrying capacity. epoxy just complicates the build due to its cost, cure time, workable time after mixing, and clean up.
Very informative. May I suggest a beginner airplane with detailed diagrams and parts etc. Also maybe a video on support products you use like inav etc. I'd like to build something
Always wondered if it's legal or so to make one of these capable of flying across a state and using something like cellular transmitting to control it
Like if you had a whole bunch of solar panels on the wings, decent batteries, and efficient motors it could stay in the air for countless hours, especially if you ride thermals to get lift
It's not. The laws are complete bullshit though so who gives a shit.
Really nice work 👍. I wil build it with my son.
Brilliant video and awesome flying plane! I wonder what you used to film your aircraft in flight? That is some great flying footage! The aircraft felt much larger in the flight video. I am surprised that it is so compact!
Thanks! It’s 1.6m in wingspan but can be customized to fit larger outer-wings to increase the wingspan
I flew a DJI Mini 2 while the plane did WP Missions.
Good looking aircraft. Thanks for the video.
Russia be taking notes for real
As Russian, who is not supporting the war, but interesting in fpv long range planes, I'm in taking notes
Гы гы гы😊
Not only Russia, dutchie here! Trying to design and build a stealth drone with a 100-300km range and a 100kg payload bay is a pretty big task…

Oh and don’t forget the blended wing body which increases its range!
Nice plane. I am really excited for the solar plane!!
Congratulations, this is really cool, unfortunately not allowed in Germany.
The Pilot must be always able to see his plane 😭
Also, pure FPV is for the Pilot not allowed 😢
USA has so many restrictions as well. Can only fly up to 400 feet, must always see aircraft, no flying in or above clouds, etc.
really nice, enjoyed this video.
The ukrainian military will apreciate your invention
he didnt invent anything they havent already been building in sheds for months.
Yes let’s support a neonazi regime!
Good one
Can we not make it military for once?
@@herbertromanski9045 you will have to talk to putin if you want that,buuuut im pretty sure he wouldn't do that.
Wow, good video. Put together with a glue gun and foam board. I guess a bigger gust of wind will just blow it out of the sky, but well for the budget simple build, this looks to be working pretty good.
It’s stable enough in scale-4 winds - Plenty wind tolerance by the flight controller
999x “You know”😂
Just take care of your hands on launch... I've seen some chewed up fingers from those props.
That’s one of the reasons I’m replacing the 14x4.7 with a 12x6
Really cool design. Would love to see a solar panel. And a straight line way point mission beating public transport. Can deliver letters from your home address to your collage.
Just an idea.
Would like to see how it performed, and the tools you are using to program and follow the flights!
Next video😎
Great build, and a great video, you know!
We all just gonna ignore the superb chase plane/quad copter filming that beautiful aircraft?
I'm waiting to see an autopilot for a camera
chase drone that automatically holds station on the target in flight
Been waiting for that my entire career! Because then I can have that particular drone record TWO of my planes at the same time, close proximity in a Two-Ship formation. (One flying autonomous and the other in control)
My Call of duty threats are viable now, thank you
Awesome build. Can I get design layout as pdf?
Thanks!
Whenever I got the time for it, I'll try and make PDF/Diagram's
That's impressive 👌
Many Thanks!
Please can you tell me what brand of propeller you use on this? I adore the broad blades!
It’s a 17x5.5 propeller, cut down to be 14”
Thank you sir👍😎
Just discovered you, i really like your videos keep doing this💪🏾
Many Thanks!
Sweet build!
