Don't sweat the schedule, build it right and safely is all that you should be worried about. Now that I said that, can't wait to see it fly.
I'd love to see the bipe re-fitted with a small engine, like a single fitted with toothed belt driven props so thrust line remains about same. with the right muffler set up it wouldn't be all that loud, and it'd gain a whole lot of flight time with just a 1 gallon gas tank.
model nutty A Honda Gx240 would be perfect. Lots of horsepower, fuel efficent, lightweight, and quiet. It could be a very fast plane with the right gearing and prop.
"Man I really wanted to *build my own airplane* in a month" I once built a model airplane over the course of a year.
*pulls AR mag out of VCR*
Wait. You don't store your spare mag in a VCR?
obviously he was watching a magpul video and switched over to "how to build an airplane part 2"
Bumpy nah I keep mine in my DVD player
@ArmchairWarrior who doesn't keep their mags in their vcr
It's called a VCAR
Been waiting all week for this, hope you hit 600k this week!
Klawz g
He can probably get it today
Go Peter!
"Oh yeah!" Koolaid Man
Gigas_ 805 lol
Yup. 600k now.
6:10 Doing a flight test at an event put on by FliteTest doesn't sound terrible, it sounds amazing!
flex on em
He was referring to if the plane was not tested yet, he did not want to be at any public event.
BWX
I think it would be cool to see him test it. Maybe I'm a weirdo. LOL
Traumatize a bunch of kids by crashing into hangar
Pete, The landing gear is going to kill you. When was the last time you came across an aluminum spring? Aluminum doesn't like being flexed. It work hardens terribly. and it doesn't matter how thick or thin it is. Replace what you have with steel, or put a hinge joint at the fuselage. The two sides aren't going to fail at the same time, so when one side fails..... Odds are you will be going fast when it happens.
I think you were proven right. This thing broke
finnaly after a week
Not boring for me. Want to see more. I build a lot of things myself without a lot of plans. Been doing it for years but still inspired by your builds
you better fly into flite fest on that bad boi
This Plane Is gonna be so SICK!!! Nice job!
When you were welding i instinctively squinted my eyes to protect them! Yeah....been welding a while. I love your videos peter.
So envy.😃
i think you're supposed to use welding mask , not squint lol
There is one thing to be said with no doubt whatsoever...Your updates are NEVER boring!..and the start was hysterical..LOL!
Thank you peter for bringing the world your content and I've been waiting all week
Im again supporting you like I did at your first plane! Keep up the good work!
The quarter inch aluminum plate sharp bend of the landing gear, at the fuselage. If that fails consider bending a larger radius then it currently has. A small radius concentrates stresses of the bending. A larger radius distributions the stresses of the forces out in a wider radius. good job I love watching your enthusiasm as you go through your projects so quickly!
4:23 We don't care about setbacks Peter, make sure it's safe! That's our number one priority!
As rough as it may have looked, the stressed skin design of your biplane's fuselage seems superior to what you are trying to do this time around.
Within limits of available vision, the fuselage you have built seems to be a single-plane truss with no rigid carrythrough structure from the front of the fin past the upper longeron to the lower longeron, just assemblies with bolted joints at points of concentrated loads.
The fin has a lot of leverage over those simple attachments. Wire bracing to the horizontal stabiliser will secure the fin relative to the stabiliser but not help this issue
The arch in the structure relies entirely on the bolted joint through two plates which are not tied together other than by the through-bolts. There are no additional webs on the undersides in lieu of welded strips joining the two plates which would be a best method.
Once you have the mass of your wings and engine attached, the fuselage may "fishtail" violently enough to loosen the bolts, elongate the bolt holes and start cracks before you can put the aircraft onto the ground.
Your method has been done before except it was a single tube structure between wing and tail. It also broke as yours may also.
The cause of the failure was aerodynamic flutter, a condition in which destructively violent energy is extracted from the airflow due to flexing of the airframe or parts of it. The tail twisted under and control was lost.
Do you have any anti-crush inserts inside those hollow tubes where they are through-bolted. Have you considered an aviation grade adhesive between the faces of those bolted pieces to avoid fretting and opening of a clearance between bolted attached fittings.
It might be a good thing if you consult with some engineers on the torsional and vibrational stresses your airframe will be subjected to which may be far more destructive than the aerodynamic loads you anticipate. They also know about the failure modes of bolted structures.
If you are using a gas engine, then it is a whole new ball game compared with your smooth running electric motors on your previous project.
Please consult with the Oshkosh folk. You will find them helpful in a safety oriented way and they will have the knowledge which will help you avoid reinventing some old design dead-ends. Please do not dismiss their advice.
Look up airworthiness directives on the Skyfox lift strut carrythough structure. You seem to be re-inventing something similar with inferior materials.

You seem to be completely oblivious to the fact that this isn't the first airplane this kid has ever built. Might pay to kjnow the background before ASSuming the need for an engineering lecture. Oh, by the way, he's not showing EVERY little detail so it's a safe bet he's addressed your concerns in some fashion already or will at some future point. Most homebuilts are assembled at least a half dozen times before they are completed.
I am not oblivious at all. That said, I would rather open my mouth and make a fool of myself than keep something to myself I later regret not having said. Been there, not going there again.
If it is all useless wordstuff then that's what it is but just maybe there is a small scrap of something useful.
I also fully respect this young guy for his energy, getting in there and having a go, not lazing around consuming the efforts of others. This clip does not indicate he was intending to use electric motors again.
The follow-up clip of his taxi tests I have viewed since show that there are two electric motors pylon mounted ahead of a single high wing. This obviates some concerns relating to the single truss arrangement.
He is too young to have to endure a lifetime disability of spinal injury because of a hard landing which might be avoided.
Further to the previous response, this clip which I have only just found vindicates your concerns as to my comments. - th-cam.com/video/O6sy5bt4D-Y/w-d-xo.html
@B Belcher - the culture of rabid anger to defend youtubers should end - i'd be willing to bet Peter doesn't need nor appreciate fans 'coming to his aid' to rudely shoot down others who are genuinely assisting through comments.
Welp, I guess I'm going to Oshkosh this year after all!
2 hours ago nice job youtube lol
Ya u are
Lel how did this guys post a comment 2 hours ago? The video has only been out for like 2 minutes by now. Good job TH-cam.
patreon lol
Victor Arellano is Oshkosh a Russian military truck making company
You're the man Peter Don't forget to put your rotor tiller up
Dude I really commend your knowledge and use of rivets welding drilling and fabricating. You are quite the inspiration and I seriously cannot wait to see what a beautiful plane you produce. That welding looked amazing!
This is sick love this channel i’ve seen every vid
Some people have dumbbells at home to work out...
Some people have dumbbells at home so people think they work out...
And there's Peter using his dumbbells when building a homemade airplane xD
I like how your dad helps you with creations and is not lazy and laying in fame as other dads do!
Looks great! One thing to consider is to make the elevator control all with hard links. Take a peek into some sailplanes for ideas and inspiration, you will hardly see an elevator with cable controls. I do not think I have seen one myself in my entire life, perhaps "basic" gliders? Fine for rudder, but for the elevator you do NOT want the, flip-flop, inaccuracies, snag, sag, oscillations, harmonics and cable breaks. A hard link control feels a whole lot more solid. There will be considerable forces between your elevator and control stick, while a very tight tolerance for errors at the landing phase.. The current elevator setup is dangerous.
Your building footage is always the best!!!
As a retired aviator and sheet metal mechanic, you should drill pilot holes (#30) first then step up to the size needed.....
The man has no time for pilot
holes!
There's a legit reason for pilot holes and stepping up to final size. Accuracy suffers and metal fatigue increases when you skip the pilot holes.
Dude, not boring at all. Great progress, don't beat yourself up for missing your deadlines on a prototype.
When I was young, I couldn't spend time with my dad, because he was busy with teaching math at academy... so jealous Peter! Good job!
For a Nylock to work, it needs threads past the plastic crown. So don't put short thread, especially on a critical element like that @4:13.
These bolts are subject to rotational forces, and should be on drilled bolts with castle nuts and a cotter-key. Similarly, the ball joints on the torque tube should have large washers under the bolt heads to prevent the fitting from falling off the bolt in the event of a failure in the ball.
3:08 watch it ,wtf 😂😂😂 he is trying to Screw the bolt in with a ratchet but no Socket😂😂😂 but man I love ur videos 👌👌
😂😂😂
lol, I wondered if anyone else noticed that. I did a double take when I first saw it.
Saw that too. I think it was a joke tho... But yeah, really lover ur videos Peter!
Trololo
r/whoosh
That intro was beautiful
Bass drops on the arc strike. Well done sir.
In a few months you will be at 1 million subs
Nice job peter! Check your instagram DM's for some lift calculations
If the only thing you did was build ultralights on this channel, I would still love it! Keep it coming! This is my favorite project so far!!!
You are a pioneer in the spirit of Sport Aviation.
Put a rotary wheel at the back to turn while you're not flying
Tail rudder would do just fine
Only in 7 minutes...
MarufTIM ikr
So fast!
nope in 16
and 28 seconds
😂😂😂
Good to see you back with another light aircraft! The first attempt was...moving....!
at 6:53 in the video i would like to see a metal bracket going close over the horizontal stabilizers pulley so there is no way the cable can jump out. Working as a helicopter/fixed wing technician and have seen on some bad cases where pulley has been worn out and the line is close to go out but is stopped by the bracket. Also i would recommend to get some Cherry lock or cherry max rivets for the hinges instead of the standard pop rivets. But it looks good and i cant wait to see it flying :)
What about putting lights on it
Like on the wings
Light strips in the interior
Now saying this aloud sounds awesome 😍🤗😮😮😮
FAA rules require him to have a strobe light if he wants to fly past sunset
Great work Peter , Hey if you had a unlimited budget would you build with carbon fiber. Would a wing shaped blimp ,like the B-2 stealth bomber filled with hydrogen an with top mounted solar panels an electric motors be a good lifting platform. With the new technology's to hold hydrogen an compress it an carbon fiber. It should be very safe today.
Is the hydrogen necessary? Lifting bodies only make lift when they’re moving; it might work better to add batteries and more motors.
A lot can go wrong with this. If peter had unlimited budget , he'd probably built a jet version :D Also compressing hydrogen isn't really useful , since you'd loose buoyancy
if you're going to go with lighter than air, go that way 100%. I've seen ideas for a blimp to be used in logging remote places that would use wings and engines mounted on rotating mounts on the envelope, which would also rotate around it's longitudinal axis. This would allow the system to provide much greater lift than what just the gas in the envelope could provide, but I imagine it would be a maintenance nightmare with all those weight bearing rotating joints. Also I wonder what the FAA would do regulations wise with a personal airship. It certainly weighs less than 250lbs.
James Burleson haha, yeah, technically.
There is a guy down in Brazil that is using what I think is a hot air blimp to deliver researchers to the tree tops in the jungle. FAA is allowing experimental hot air balloons so I expect they have a way of staying legal. Only, the weight limits apply without the lifting effect of the gas, whichever you use IIRC.
That’s pretty cool
Good luck Peter! I can’t wait to see it fly!
Dont fly it at FliteFest, Fly it *to* FliteFest
how much did it cost. i love this project
I luv flying and vehicles but its not always possible for some people. This channel has all the stuff that I would luv to do.
You have an awesome Dad and Mom. I loved that he got in the slay drone first. You two are a wonderful testimony of Father / Son ... Jesus bless you both.
3:06... I don't think that's going to tighten the bolt. 😂
Diy money please, where did you find money? I want to make thoose projects but i don't have money , i don't have items :)
Jobs usually find you some money. However if you DIY that unproffessionaly you probably get shot.
Creature Programming TR if I was a betting man- I would guess that he got a lot of his equipment from sponsors after he left Flite Test to create his own channel. In other words, he worked hard, got himself a good reputation, and played it smart.
Don't attempt this man. This isn't something you can easily throw together in a weekend, plus without the proper experience you could literally die, kill someone else, or break many laws doing it improperly.
I am from Turkey , 1$ is 4.60 TRY so i don't make like this projects anytime :(
Vnifit Experience? You need to watch some more of Peter's past videos.
I literally love you dude.
Huge hugs from a guy in Canada.
Alas! The Sripol MkII ! Keep it up Peter & stay safe as always!
Will you ever do more 3D printed boats
Bo Bob bobob he has some 3d cad models on his website if you are interested
A speed boat is in the works!
Video
I like it when my favorite TH-camrs get recognised and become successful enough to do the projects they want to do.
By far possibly a better performer yet
Why is it taking you so long to make an airplane? Give me a sheet of paper and about 2 hours and I can make one, step it up man.
drewbot02 takes you two hours to make a paper airplane?
19th view, 3rd comment
Does anyone care?
I care
Curious Airlines aww 👍
Not really
I care, human.
best intro i have ever seen of any show, video, or movie of all time
I admire Peter's work
First to comment
Nice work Peter. Looking forward to the next installment.
The first TH-camr to build a flying machine from scratch
Like others have stated, safety is your no 1 priority, schedules and "reasons" can all come second.
I like this design better than the previous one, although that was a charming aircraft. Seems like you are trying to build it sturdier, and also perhaps a bit lighter than the first project. Aluminium is amazing stuff! Regarding your age and work morale, we should be seeing you getting into spaceflight in no time at this rate!
Best of luck, take care and can't wait to see this thing fly :)
Major props- no pun intended. Building your *second* plane. That’s major genius material. So impressive. Godspeed on your latest.
See you at Flite Fest Peter, Way to go. Close to 600K well done.
Glad I live right down the road from Oshkosh
It's coming together very nicely! I'm happy to hear you're coming to Flite Fest, by the way.
Peter, with your skills, I could barely imagine what could be done with a vacuum pump and some composite stuff... !!
From the very limited footage I've seen of it it seems to be way better than the last one. Coming a long nicely too.
Watched the livestream at midnight my time (BST) was totally worth it. Best project yet!
Groovy! Whadda you mean not exciting? It's an aeroplane!!
Awe, yeah ! SO cool Peter !😊❤
Great to see your progress. Fantastic.
Looking forward to seeing this at Flite Fest! :)
Your talent is most intriguing , beyond anything I’ve witnessed on the internet. Keep up the spirit ,good luck and happy flying.
I cant wait till the madden flight.. Your a genius.
Safety first Peter, no rush.
Lol that beginning tho xD
Finnaly the second part
Beautiful job, dude! 😊
Love seeing the updates, can't wait to see you in Oshkosh! Keep up the great work!
All the best sir can't wait to see it finished
Careful with the aluminum landing gear struts. Aluminum fatigues. The more cycles, the more micro-cracks it gets. But steel does not suffer from that problem. As long as you never exceed the yield stress, steel can theoretically sustain an infinite number of cycles. That's why it is used for springs a lot. Just inspect your gear for cracks every time you land and every time you take off. Maybe with a magnifying glass.
That intro made my weekend. Well done
ahhh finally we get to see more on this plane
Can't wait for maiden! Suggestion:
TIG welding will save you the weight of a lot of nuts and bolts, good luck!
Man! Way better design so far! Lookin sleek! :D
Amazing work!! I can't wait to see you flying in this beauty!!! keep it safe!
Your content is also my favorite
Yessss. Flite fest is going to be lit
Dude, dont worry about time. You build it ,guarantee we will watch!! lol Ain't everybody literally building their own frikn airplane from scratch in their garage! And this is #2 so chill brother we can wait a bit! Really wish someday you'd design a kit plane for sale! Really enjoy the videos
Keep at it sir! loving the progress!!!!
You should paint it red, it would look so much cooler
You guys brighten my day, thank you
Peter has always been good at cranking up the volume.
This is amazing! congrats on everything you're doing and the work put forth!
It’s exciting if it was with FliteTest
Very cool! Your video powers are strong too. Lots of fun to watch.
Congratulations Peter, you just hit the 600K subscribers mark!
Awesome Pete. Long time fan. 👍🏼
