DIY Electric airplane mk2 (Pt1) 

YES Peter!! Looks like a much better design. Can't wait to see more of the build!

The people at Lowe's must think your house is energy star insulated by now.

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!

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!

Knowing Peter, he could probably make a functioning Iron Man suit out of RC plane parts if you gave him enough time.

the other plane didn't kill him so he is trying again

Really cool once again! It would be nice if they had contra rotating motors big enough for that, up to 16% increased efficiency.

Speaking as a pilot, you are very brave and absolutely insane!! Good work, you clearly are very ingenious...

DIY plane mk2 now with more metal and less fear of death :D

So awesome Peter, nice work! Can't wait to see you at Oshkosh!

how many pounds of baking soda can it carry to some random country like Colombia? asking for un amigo.

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.

Here we go again! Best of luck Peter!

So freeaking cool Peter!! Can't wait to see the final product! You are amazing

Peter, I tested your plane in kerbal space program... Not good news; It exploded... Maybe I need more boosters..

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.

Was low key hoping for a human sized guinea pig lol

That last frame of the comments about the prior build. Username :23, you're my new hero.

When ever I watch these videos it makes me so satisfied

Great work Peter! I'll be watching!

Queue the “Peter is going to die” comments

You just can't be satisfied huh...

Reminds me of the Yando Goat Glider. It's a pretty cool DIY homemade ultralight glider that could easily be made powered.

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…

Just go to school for your A&P cert and do this fulltime!

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? ;)

Let the build begin!!! The last plane build was great. Can’t wait for this one to unfold.

OMG i am living for this new design! so excited to see this fly also!!

the profile fuselage was a grate idea keep up the good work

When my life is dependant on it.. I'll take strength over weight every day. Have Stephen teach you the glory of safety wire😂

Good job man. Keep it up. If it does well, I hope plans will be available! Looks like a simple, straight forward build!

Good luck! Glad to see you are teaming up with some EAA guys and all. I like this design

Looks like a twin-electric take on the Affordaplane :)

Holy hell you are ambitious. I love it, and that looks awsome.

Sooo excited. I was a bit late on the last one but I’m gonna follow this build!

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

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.

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 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.

Hey Peter, great design...I really like the esthetics of this one. I think you should keep making this transition from RC to full scale, it is very entertaining and as an RC enthusiast it is inspirational.

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.

“The guy who tried to kill himself.... Twice...”

Yes yes YES! The last one was super cool, and I know that this will be better than the other one!

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!

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.

So the submarine is the next build , right? Awesome project ...

Peter I’m such a huge fan of your work I got so excited like a little kid when I saw the title for the video I loved the previous airplane project I can’t wait for this one keep doing what you’re doing we love it and thank you for keeping us entertained and living the dream LOL

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

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.

This is cool! The fuselage design looks very similar to the affordaplane.

Peter ! go for it this one looks very promising,delighted to hear about Oshkosh plans and look forward to hearing more on those,delighted that you are building the Mk.2.

All of your work inspires me there's no channel like your I give you all my hope and support

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?

Yeeeeeeesssss!!!!!

Wow, you guys are great I absolutely love the stuff you guys do and you should keep it going and this project looks amazing.

I think it's awesome that you always try to improve your work.

Maybe I can use this aeroplane to fly out of Africa and come to America like you, my friends🙏🏾I wish for better life!

Old plane be a thicc boi

The photography and editing on these is really beautiful.

Outstanding fabrication werk as always! Pretty keen to see this new plane in the air.

Peter... you are just awesome. I wanna be you. Please?

make a 3D plane from the design and see if it will fly

YESS, I LOVE THE FIRST MK NOW I CAN’T WAIT TO SEE WHAT YOU HAVE STORED FOR US THIS TIME!!!!!👌🏼😌👌🏼

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)

Will we be seeing this as flite fest?

**Modern age wright brothers**

YES! Finally, more airplane building! :-) Great stuff! Love the new design!!

Yeeesss, I loved watching you build and fly your other plane I'm so happy your doing it again

DIY Electric airplane MK5 - Working jet turbines! (10 seater private aircraft)

1 million subs when?

I cannot wait for this new one, loved the last airplane series

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!

2:20 ASMR 😍😍😍😂

i dont even know how the other plane worked

Peter Sripol number 1 craftman, awesome sir !

Cant wait for both airplanes to fly together! That would be awesome!

Homemade rocket ?

Who else came here and compared this to the African fella who tried building a plane from the village ?

Awesome man. Its so amazing that u actually are going to fly in it. Keep up the amazing work.

Sweet loved v1 will be following this build closely

what? no DIY helicopter? Pathetic

you barely even flew the old one!

Very cool... excited to see this progress.

Part 2 now!!! Waited all winter! Brain can't wait any longer! 💥 mind exploding!

If you add solar panel at the top it will fly way longer

amazing work, God bless you.... All the best Peter....

You are awesome, literally! I would love to see a team up with you and Adam Savage. 🤞

This is literally the best content on the entire internet

Nice man! Love all your builds! Can't wait to see this one fly!

Can't wait to hopefully see you and the airplanes in Oshkosh!

Freaking awesome. Can't wait. Wish you could break for more progress videos. Keep em comin

Your doggies are so cute. Love seeing you build these airplanes. I'm working on my own--and taking some inspiration from you.

Amazing! I just can't wait to see more!

To Peter; your videos and air craft seem to amaze me. I am hooked on your channel.

Thank you Peter! Keep up the great work!

Very cool to see another microlight build underway.

Peter, Overkill is GOOD on a project like this. Great job.

Greetings Peter, you make engineering and aviation rather fun. You have good sound quality, great time-lapse video to move along your projects and that keeps the audience watch; and I really enjoy your music selection. For a safety improvement in your shop, wearing SHOES might be a good idea with all of that metal debris and heavy parts. Improvements for your videos. You really don't need to be wearing a shirt! There are lots of your audience that just want to see you working on your plane. You are handsome, talented, cute, and fun to watch as you make new planes. Best wishes, Brennan Aeronautical Scientist

This dude is aweaome i love the flying spirit

I will see you at Oshkosh then. Good luck, be safe, stay safe.
