Looks much better overall. Monoplane much better than biplane. Would look to seeing the following features: 1. a good high lift airfoil, with drag as a secondary consideration. optimized for loiter/flight times. 2 a higher aspect ratio wing. If you have an efficient airfoil, a higher aspect ratio makes everything better, except for adverse yaw, and that's a solvable problem. Think early sailplane.. Do not need a large chord to affect the air if the airfoil is optimized for sink rate. The CL is achieved in a relatively short chord, and for the same drag, you can effect loft on a much larger volume of air. Same principle as the large prop diameter. you would not want short, stubby prop blades, would you? The twin lends itself to that nicely. 3 the motors as close to center as possible, without interfering with each other, so that if you lose one, the offset thrust will be minimal. 4 a T tail would have been better, but the tail you have will work fine, and will allow for better controllability at very low speeds, provided you learn to give the throttle a blast, and still have the battery power to do so. 5. make a "Tesla" style battery from 3500mah NCR18650GA cells. Much better gravimetric energy density, about 187% better than lipos. Not sure how to get sponsorship for them, but would drastically extend flight times. 6 high amounts of ripple current meant that the batteries should be kept very close to the speed controllers. And the speed controllers should be kept relatively close to the motors. If you have to extend any wires, extend the wires from the SC to the motor. this is a major safety issue, and one very often overlooked. 7. find a way to brace the leading edge of the stabilizers, so that they do not get into an oscillation. happens way easier on larger scale. 8 I personally would have made the pilot's position lying back reclined much more for aero, but that's a personal choice, and can't tell you that what you're doing is wrong. again think glider... anyway, just my two cents. you have more experience by now anyway.. best of luck, and don't listen to anyone being critical without helpful criticism. cheers!
I always enjoy your comments. Well Thought out, thorough, full of useful info, and offering CONSTRUCTIVE criticism. Cant wait to see how your input is taken by Peter on this build!
Curious, why do you think a T-tail would be better? Having the accelerated slipstream moving over the tail will make the control surface more effective than if you had a T-tail. Also, there's definitely a fine line with a high lift airfoil. You'll eventually get to a point where you have so much lift that the induced drag is too great. You end up with a stupid slow plane haha. Great insight though!
But the propwash drops, so you'd get more force from the propwash if the horizontal stabilizer is where the propwash is actually going to be (below and behind), not directly behind it.
Higher aspects may make all aerodynamical properties better; but all mechanical considerations all that much worse. Thats the very good reason peter went with a biplane last time. And this build also seems more geared towards 'DIY budget' than 'carbon-fibre-all-the-things'.
Adam Burdett when you cheat death you want do it again and again that's why he's building another plane also I think he should build a helicopter after this
Honestly KSP has fairly poor and inaccurate aerodynamics because it's more about space physics. But yeah, It probably will crash lol. And yes, if it crashed, just add more boosters and more struts.
I love how he says he's building an airplane then gets right into a montage, Peter... you know an airplane is a big step up from your normal RC stuff... then a hear he had a mk 1 which had no plans at all!
With the flying leaf blower and the flying drill moter plus a bunch of other experiments. Hard to believe Peter had any time to build electric ultralites. Wish I had a shop like his.
Cool plane and all! Totally supportive! However, have you considered torsion and bending moment on the tail? In other words, what if the front roll to the right while the tail roll to the left? Might lead to fatigue problems. Also, vibrations, bending moments and instabilities along the Yaw axis since the areal moment counteracting this is pretty small. Have you done some kind of simulation (FEA/FEM) to confirm that the structure can take the load? Aluminum 6000-series is cool and all... but have you heard of 7075? ;)
electric motors produce very very little vibration, unlike gas engines so only aerodynamic vibrations will be a factor (small) but yes, if the tail section isn't stiff enough, it could twist. though it looks really stout from here :)
I thought you were doing an RC Plane but this is a Real Plane. You're a lucky man to have a place to build & to have all the tools to do it. Very stimulating to see this and to see what any of us could do if we set our minds to it...? peace
I’m concerned about lateral and torsional rigidity. Your entire fuselage is only strong in the up-down direction. It will sway side to side like a noodle. If you end up rolling at all when you turn, I think you’ll find that the whole fuselage bends in a way that is not good.
+1, if he's gotta waggle the rudder for some reason some weird stuff could start to happen. Moving the control surfaces rapidly on full runup should be a good indication.
I think this design may be prone to flutter... Triangles are your friend. For a proof of concept, it would have been easy to find a fuselage from an ultralight that was proven a successful design already... maybe make the wings if one has to have some "I built it" kind of input, but a BeLite fuselage or something similar would likely be way safer.
You should attach solar panels to the top of the wings and route them to charge the batteries during flight. That way, you won't need to worry about the charge during the day.
@@MrBiggieJay solar panels are too low output. You need a really BIG main wing to put enough panels on. Think glider/sail plane. Large bungee cord to launch.
Your mind is working fast. You are making a conscious effort to keep your "thought speech" in sync with your delivery. This a compliment. You are genius. I guess if you were savant, I would need to state that. If not, you already know. :-) Great build.
You will have torsional and lateral issues with the 2" Square section frame you need depth and a bit of triangulation for stiffness. The area around the cockpit will probably ( almost certainly) have torsional issues. It may work out fine for a very gentle flight. The frame is certainly overdone in one dimension. I really like your design but some rudimentary FEA would be a good idea.
This looks far more like a traditional ultra light than the first. The first plane was an amatuer triumph and was superb!.....i said it before, i felt moved when it first flew! Keep it up!
Have you look at the Goat? You can download the goat plans for free. Your design looks almost similar to the goat, I saw one video where a guy mounted a large RC engine behind the pilot and use that for power to fly. I believe using a large RC engine will save a lot of weight compared to the batteries you will need and I believe you get longer flight time too.
The aft fuselage needs more bracing to sustain the rudder side loads. It looks inadequate in both bending and torsion for large rudder load. Look at pictures of primary gliders to get some ideas of how this is done.
You know how we joked he would die with the plane.... I think the helicopter would be a bit more of a problem. maybe if he makes 2 or 300 RC helicopters first. oooh or a quad.
Dang I wish I was going to Oshkosh this year! Peter you should add winglets, some vortex generators on the wing, and have flaperons mechanically mixed into those ailerons! Can't wait to see the rest of the build!
What happened to making a small scale model first. Ivebeen wondering what you were making on Instagram but now I know. Also how do you get the motivation for this?
GaetanLePelican Significantly more complicated, expensive, and dangerous. You can't even buy rocket fuel without having it specifically manufactured for your rocket. Not to mention, launch facilities, guidance systems, and just the math for making an efficient nozzle. It's very complicated, and a huge step up from an ultralight. Even a small scale hovering vehicle is a large undertaking.
I used to work for a company in the UK called Aerotech International Ltd... they have not traded for many years as the company folded a long time ago... but we manufactured the MW5 Sorcerer Microlight aircraft both built and as a Kit Form... which I believe was designed by Mike Whittaker - although we did design and produce a variant of the aircraft called the Sorcerer MW5K which had a tapered wing as opposed to the original design which used a parallel design from root to tip... it made me smile a great deal watching this video as it reminded me of some of the processes we used in putting a Sorcerer together... thanks for the Vid... :o)
Peter - Your videos put a smile on my face. Great production value and interesting content. Makes me feel good about our future… I know it’s in good hands with youngsters like you building the future. Really love the DIY electric plane. Thank You…
I thought I was sub'd to you before, but I am sub'd now. I followed your previous plane build and I was impressed! This new plane really looks great! Best of luck buddy!!!
Looks great Peter! Just the tail seems very well built to take vertical loads but horizontal looks a little skinny. Maybe some wires from the tail to the wing would help if necessary. Build and Fly Safe.
YES Peter!! Looks like a much better design. Can't wait to see more of the build!

hmmm this sound suspicious
yes
Enough for a good time, pal
DIY plane mk2 now with more metal and less fear of death :D
Adam Burdett when you cheat death you want do it again and again that's why he's building another plane also I think he should build a helicopter after this
quashon walker if at first you don't die or get seriously injured.... You didn't do right
Peter, I tested your plane in kerbal space program...
Not good news;
It exploded...
Maybe I need more boosters..
Honestly KSP has fairly poor and inaccurate aerodynamics because it's more about space physics. But yeah, It probably will crash lol.
And yes, if it crashed, just add more boosters and more struts.
Especially if a Kraken appears
You can never go wrong with more boosters
Use FAR
ksp never lies
the other plane didn't kill him so he is trying again
Hell ye.
LolPlane I know ,right?
jealous couch potato
I love how he says he's building an airplane then gets right into a montage, Peter... you know an airplane is a big step up from your normal RC stuff... then a hear he had a mk 1 which had no plans at all!
Knowing Peter, he could probably make a functioning Iron Man suit out of RC plane parts if you gave him enough time.
If he teamed up with the hacksmith they'd have it done in no time!
ya
RC pi - three years later and Hack Smith is nowhere closer to flying.
10 out of 10 correct
Really cool once again! It would be nice if they had contra rotating motors big enough for that, up to 16% increased efficiency.
So awesome Peter, nice work! Can't wait to see you at Oshkosh!
Tucker Gott what’s Oshkosh?
Oliver Kayi it’s the largest full scale fly-in/airshow in the country
A toy store
next up: diy paramotor?
Check out the channel "PDWhite" for DIY electric paramotors.
With the flying leaf blower and the flying drill moter plus a bunch of other experiments.

When my life is dependant on it.. I'll take strength over weight every day. Have Stephen teach you the glory of safety wire😂
Here we go again! Best of luck Peter!
Let the build begin!!! The last plane build was great. Can’t wait for this one to unfold.
That last frame of the comments about the prior build. Username :23, you're my new hero.
Your balls don't have a license either remove them at once. thank you for pointing that out that has made my day. lmao
RMD Cade lmao
ahaahhahaha
Way to go
Very cool to see another microlight build underway.
Queue the “Peter is going to die” comments
Peter is going to die
Hey Sit how u Doing
I used to be one of those commenters but this one looks far sturdier
hi guy how I doing
Pedder goin to dead
All of your work inspires me there's no channel like your I give you all my hope and support
You just can't be satisfied huh...
Great work Peter! I'll be watching!
Was low key hoping for a human sized guinea pig lol
DIY electric airplane mk3
We all were
That ending cought me by surprise "GOOD WORK PETER"
Just go to school for your A&P cert and do this fulltime!
Thank you for putting that red arrow in the thumbnail, Because if you didn’t I would have missed the RELLY F’IN OBVIOUS AIRPLANE
Looks like a twin-electric take on the Affordaplane :)
Andrew Williams that was my first thought when I saw the fuselage.
Yeah!
It does share some similarity! Good catch!
Absolutely correct!
That's what I thought..."Electric A-plane"
When ever I watch these videos it makes me so satisfied
“The guy who tried to kill himself....
Twice...”
...and FAILED!
Nvm im a dumb shit.
i swear, i thought he was gonna die with that 1st one
he surprised me
Atticus Draco I was genuinely worried about the wing spar
Ryan M. If every human think like u think,maybe the world still ancient till this day..lol
The photography and editing on these is really beautiful.
Holy hell you are ambitious. I love it, and that looks awsome.
Good luck Peter!
the profile fuselage was a grate idea keep up the good work
Speaking as a pilot, you are very brave and absolutely insane!! Good work, you clearly are very ingenious...
Cool plane and all! Totally supportive!

Aluminum 6000-series is cool and all... but have you heard of 7075? ;)
MrGrebgnet He isnt building a 777.
RC Hobbyist Extreme its still subjected to forces that need to be taken into account during the design...
That thing is built like a tank. Also it's almost exactly like the thirties and forties basic glider designs, which were very robust and durable.
[Karri] Is it? Didn't they mostly use body box sections to support the tail?
electric motors produce very very little vibration, unlike gas engines so only aerodynamic vibrations will be a factor (small) but yes, if the tail section isn't stiff enough, it could twist. though it looks really stout from here :)

Nah its fine. Triangles and such...
The tools used in the montage look strangely satisfying...
You should attach solar panels to the top of the wings and route them to charge the batteries during flight. That way, you won't need to worry about the charge during the day.
Won't that make it too heavy?

Cant wait for both airplanes to fly together! That would be awesome!
DIY Electric airplane MK5 - Working jet turbines! (10 seater private aircraft)
Seems totally accomplishable in his less than 30 foot long garage.
Science Alliance Depends how many times you cut the plane in half
Well, for whatever reason you would wan't to "cut the plane in half", I hope he won't "cut" the engine.
Sooo excited. I was a bit late on the last one but I’m gonna follow this build!
what? no DIY helicopter? Pathetic
You know how we joked he would die with the plane.... I think the helicopter would be a bit more of a problem.
maybe if he makes 2 or 300 RC helicopters first.
oooh or a quad.
Not even a DIY spaceship! Unsubscribe! ;)
He should totally make a quad with 4 paramotor motors
batt3ryac1d Thats a furze/sripol collab I'd like to see!
If you count drones he pretty much already has. Maybe.
Oh my holy cow just when you think peter's taking a step back he comes out and raises the bar again
Yeeeeeeesssss!!!!!
Dang I wish I was going to Oshkosh this year! Peter you should add winglets, some vortex generators on the wing, and have flaperons mechanically mixed into those ailerons! Can't wait to see the rest of the build!
1 million subs when?
Good luck with your second airplane Peter I'm confident it will be a success
What happened to making a small scale model first. Ivebeen wondering what you were making on Instagram but now I know. Also how do you get the motivation for this?
Do you need special motivation to do cool shit? I feel sorry for you. Wait, no I don't
Why did you bring up porn? is that what they call transference? or maybe you're into older men?
EURIPODES doesn't shock me that older men come to your mind when porn is brought up. But I don't judge. You do you
Have you told your parents? what did they say?
Yes yes YES!
The last one was super cool, and I know that this will be better than the other one!
Will we be seeing this as flite fest?
when you hear the buzz of the electric motors look over the hill and there it will be arriving. hahahaha
Are you gonna fly it straight into a horde of orcs Gandalf style?
Do it on Sat as that's the day everyone gots off for FF
Reminds me of the Yando Goat Glider. It's a pretty cool DIY homemade ultralight glider that could easily be made powered.
make a 3D plane from the design and see if it will fly
Part 2 now!!! Waited all winter! Brain can't wait any longer! 💥 mind exploding!
i dont even know how the other plane worked
You should make a company producing light aircraft!! You could be a new competitor in the light aircraft market. Great video!!
Who else came here and compared this to the African fella who tried building a plane from the village ?
Peter you are one talented young man!
Homemade rocket ?

Significantly more complicated, expensive, and dangerous. You can't even buy rocket fuel without having it specifically manufactured for your rocket. Not to mention, launch facilities, guidance systems, and just the math for making an efficient nozzle. It's very complicated, and a huge step up from an ultralight. Even a small scale hovering vehicle is a large undertaking.
Tyran L. Ues but no a humaned rocked just a mini rocket
I used to work for a company in the UK called Aerotech International Ltd... they have not traded for many years as the company folded a long time ago... but we manufactured the MW5 Sorcerer Microlight aircraft both built and as a Kit Form... which I believe was designed by Mike Whittaker - although we did design and produce a variant of the aircraft called the Sorcerer MW5K which had a tapered wing as opposed to the original design which used a parallel design from root to tip... it made me smile a great deal watching this video as it reminded me of some of the processes we used in putting a Sorcerer together... thanks for the Vid... :o)
you barely even flew the old one!
Dude I hope you get into the best college, get the best education and join the aviation industry. A fearless unfettered mind is a beautiful thing.
This looks so much more legit than the first design!
Best news since your last aircraft build!!
Lol, awww, I kind of liked the foamie build. Felt a lot more shade-tree to me.
Peter - Your videos put a smile on my face. Great production value and interesting content. Makes me feel good about our future… I know it’s in good hands with youngsters like you building the future. Really love the DIY electric plane. Thank You…
Keep it up! You'll end up in the history books!
Peter, Overkill is GOOD on a project like this. Great job.
This dude is aweaome i love the flying spirit
amazing work, God bless you.... All the best Peter....
i will loved your works, and my uncle is helping with me building things.
Omg hes doing the pilotable airplane build again!
Lucky to get such amazing tools shop.
I am so building one!! Progress looks amazing so far.
I cannot wait for this new one, loved the last airplane series
YEAH!!! Soooooooooooo cool!!!
Can't wait to hopefully see you and the airplanes in Oshkosh!
I will see you at Oshkosh then. Good luck, be safe, stay safe.
you are the craziest but coolest but smartest person ever
This is what I've been waiting for. I know you can't always do ultralight vids but they are good, as are your editing skills. Top stuff.
I thought I was sub'd to you before, but I am sub'd now. I followed your previous plane build and I was impressed! This new plane really looks great! Best of luck buddy!!!
Looks great Peter! Just the tail seems very well built to take vertical loads but horizontal looks a little skinny. Maybe some wires from the tail to the wing would help if necessary. Build and Fly Safe.
You deserve more attention. Your videos are amazing!
fantastic video! and the build looks wayy safer/better this time!
Outstanding fabrication werk as always! Pretty keen to see this new plane in the air.
