From what I've heard soldering these make a much lower resistance connection that spot welds. It can be very safely done with the right technique. Use a very large soldering tip, high temp and good flux. Just keep the heat on the cell as briefly as possible, 2 or 3 seconds.

Thank you for your great work. To reduce the drag and weight, you should reduce the thickness of the blades as much as possible. This is where you will save energy and improve efficiency, from what I can see.

that's a cool garden

Its almost next year.. Better start charging those LiPo's and post some new content.

I wonder how much of a role the material used in manufacturing the toroidal propellers play as a factor of their performance. So far it seems that each time someone (outside of MIT) tested these propellers they were less efficient and not really more silent than the regular ones. So far it seems that even if guys at MIT were right, the toroidal propellers are too difficult to manufacture properly for them to be worth it.

Maybe a repeat comment but can you give it a try: instead of a filled counterweight make a working wing which will generate lift thicker than normal prop so it will act as counterweight as well. 1) it will solve one sided lift generation and bearing issue 2) since frequency generated by different shapes might reduce high pitched noise.

try p50b and put amp limit to 60A

Amazing video, what camera are you using, and what LUTs because that footage is amazing

Brother Please don't stop making videos like this, We love you so much brother ❤️ I just came here from one of your videos which title is lipo vs li-ion and that is so cool. Please make more video like that. Love you ❤️

where are you broo ? miss your video

Put an naked 03 on it then u don't need a gopro, save some weight

imagine an egg shaped propeller that is a solar panel and the egg is a tube with a barbed drive cable within that pulls weights in and lets them fly out to the narrow end of the egg. this could enhance lift and guidance in a low gravity thin atmosphere environment

What do we know? And how do we know it?😀

Great drone footage. Can I use a 5 second clip of your video. I will credit you. Cheers.

LiIon batteries can be used up to a cell voltage of 2.5V (2.7V recommended) just before landing. The increased weight of the quadcopter may be a disadvantage.

Is there any way to input a DAT airfoil profile instead of freehanding the profile?

I believer the low voltage for lion is less than lipo

Great video! That place has been on my bucket list for quite a while now

It is a 2 dimensional thrust vector over 5 Positions of thrust counter rotating 360° from 10 angular momentums = 24 Dimensions for 12 Attitudes Drags 2/5√360√10=24 Five blades, not three

Nice 👍🏼 avata?

Hola amigo, excelente video con las baterias Molicel, una consulta; sabes si puedo crear un pack de baterias 11.1v 4200mah para el Drone SJRC F7 4K? es un Drone casero, gracias

it would more helpful if you can tell the setup for the toroidal propeller

if i want to make lio battery like 6s 22000mah lipo battery which molicell should i use. And how it will work for hexa copter . how many parallel 6s will needed for it.

Andrew Tate knows so much about toroidal propeller designs. Amazing

You are losing so much flight time and for what? Lipos can go much lower and it doesnt save your batteries at all! Lipos go by charge cycles NOT how low you go…… the molicells I run to 2.5 and its fine! Its a very dense batt you cant hurt em if u stay above 2.5….. geez

Great video! Do you know what the rules are/how strict drone usage is around the Big Buddha? I’ve got my CAAT and NBTC underway 👍🏻

You are making yourself a master of the field. Thank you for posting.

Too much yapping not enough flying

Can we have a video on how you made this li ion 4s pack?

What about the Zipline tri props?

Lawnmower props, extra flight time? extra thrust?

Thank you !

Liking your style bro ... relaxing and open delivery style - KEEP IT COMING. Such a freshness to the usual fast paced and yelling type vids that litter the net. Im too old for that style .... 😅😅

how's it going bro! glad your still making vids. im in Thailand now. came on holiday, but I just started flying fpv so its also my first exploration shoot. and wouldn't you know it, broke my ankle in Koh change first fpv outing... but even thought I cant walk, I can still fly!! im in Chiang Mai now, be in Phuket next week. got any advice for a novice fps pilot in Thailand?

How was it so empty?

I can confirm that the bi-loop does not work as a boomerang even when split and re-formed at a 63 degree angle.

> Fusin360 Free for noncommercial use. Yeah... no thanks. "Drive up adoption with it's free until gaining a critical mass, then start changing the rules" is the oldest trick in the book; I'm not ever taking the bate. I'll stick with FOSS/FreeCAD. Yeah, it's a buggy crashing mess, but at least it's never going to be actively malicious at a later date. Bugs will get fixed, can't fix greed.

2 years later, the Molicel P50B is promising 400 watts per cell.

was good for me

good to see you still kicking stay safe and Happy new year

Hola ash soy George parra. ..nice video

Awesome to see you in spirit. Love that little drone of yours coming back to you in homage. Beautiful blue lake and landscape. Looking forward to a luminous outlook in the New Year, for you my dear. and all of mankind. Much love. Always. Blessings.

Thanks for sharing, your vids are always great. Wishing you an awesome new year.

Kinda hate the lack of Videos but super happy you have uploaded something and as usual awesome footage and so jealous of the footage.....Keep uploading buddy and enjoy what your doing !!!

I don’t care 😂

Good to see you doing well and getting Job you like " I guess ", Do what you like and enjoy it, Striking not Stressing 😁 Quick question, what do foreign need to fly FPV in Thailand?

Hello, Many thanks for sharing this tutorial. You have done great and brilliant design job. I have seen many guys trying to test your propeller on their own design on Utube. Althou MIT has not shared any info related to their standard design, I am trying to modify the prop design and studying its performnce. I am not used to Fusion 360 ...I work with SolidWorks. Thanks to you for providing the stl file, however it is very difficult to modefiy such complex geometry in Solidworks. So, could you please save it as IGES file so it would be easier to work with under solidwork if possible ? Thanks for sharing your fabulous work. Laith
