Making a College Landmark Into a Rocket
Просмотров 605Год назад
For the past quarter, I’ve wondered if my knowledge of rocket building can make things other than rockets fly… like a building. So I made a 3D printed 1:60 scale model of Stanford’s Hoover Tower. And as it turns out… it CAN fly! Standing 4.5 ft (1.4m) tall and weighing 14 lbs (6.3kg), the tower took flight on June 3rd, reaching an apogee of 396 ft (121m) - slightly higher than Hoover Tower itse...
How to design foam board RC planes in Fusion 360
Просмотров 5 тыс.Год назад
In this video I show my workflow for designing foam board RC planes in Fusion 360, which can be laser cut to create highly accurate planes quickly. The plane designed here was made into kits and distributed to members of the Stanford Flight Club to build, eventually giving us seven new planes to fly. To see this project and others, visit my website at lawtonskaling.sites.stanford.edu
Massive Cardboard RC Plane
Просмотров 2 тыс.Год назад
I've always wanted to build a massive RC plane, but didn't want to waste foam. I decided to try cardboard on a small plane, and to my surprise it worked great! While not quite as strong, it has fewer fumes while laser cutting, is cheaper, and is more sustainable, and for quick prototypes it makes a great choice of material. This plane was built over the course of a week, with support from Stanf...

Stanford Student Space Initiative June 2022 Rocket Launch
Просмотров 4532 года назад
Stanford Student Space Initiative went to FAR for our 49th rocket launch on June 3-5 2022, and our first time competing in the FAR51025 competition. We attempted to launch a 2 stage rocket to 25,000 feet using an M and K motor. Additionally, Stanford's liquid fuel rocket team came to attempt to launch their Nitrous Oxide and Kerosine fueled liquid rocket for the first time ever. More info Stanf...

ok
Thanks for the tutorial
❤❤❤❤
i am going to reupload this video as if it is mine on another channel so you cannot find it stay safe
Excelent work, it helped me a lot with my new design
How do your pieces fit so perfectly? I cut mines very carefully yet when I go to glue everything together, everything doesn't fit perfectly like yours
0:26
how can I delete variables
In your calculation example, 22/40~0.55, can you explain more?
I've been looking for so long to find this video, thanks so mich
is any kind of cardboard good for rc planes? i wanna make a flying wing design
Everyone like and subscribe for more content like this!!!!
Your voice is terible can’t understand a word you’re saying. Also to fast. Probably a good vid if it was possible to understand .
I've been begging for this video. The algorithm just now found it for me. Thanx for making it even though I've mostly worked it out myself it was still good to see how you do it.
👍
very helpful, thank you!
If I want to rotate the arm and keep the end effector at the same starting angle (i.e., change in end effector angle = 0), the formula in the video would suggest a gear ratio of 2:1. That doesn't seem correct. Am I using the formula incorrectly?
if you want the end effector at the same angle, then it should be a 1:1 ratio, which is a parallel 4 bar linkage. at the same time i'm having slight trouble understanding the question so my answer might not be that helpful
@@notsaltysugar I am aware we could use a 1:1 gear ratio to keep the angle the same. At the 4:00 timestamp in the video, there is a formula to calculate the gear ratio based on the desired angles. I am validating the formula with a 1:1 gear ratio scenario and got a different answer using the formula provided. I am wondering if I am using the formula incorrectly.
Greetings, In your Fusion model, you show the arm and the end effector both rotating counterclockwise. If you are using a chain and the large gear is fixed, doesn't the small gear and the end effector rotate in the opposite direction, clockwise?
Super cool! Very similar to a process we went through for Power Play last year: ruclips.net/video/Fc3pCnbL0tQ/видео.htmlsi=DtLb_yzA8LBUXEpM
Still doesn't work bruh
Same
@@kellyxmarie I used ctrl everytime I click along with enter
Awesome!!!! Was nervous when the chute took a few beats to expand but wow… thanks for taking me on that journey! That’s alot of 3D print time !
Nice demo and explanation
I like it! I fly a couple of foamboard airplanes and the folks at the club will constantly try to tease me by calling them "cardboard" planes. Be fun to show up one day with an actual carboard plane that both looks and flies good - wonder what they would say then? 😊
ok so as soon as I added the offset I got a ton of fillet errors and yeah
Does anyone know if there's a reason why mine won't change just by clicking on it??
Did you ever figure it out? Bc same
@@robertconnormcgee7309 sorry, still haven’t
I guess learning blender was kinda useless. Not found a way to flatten say a curved top plate to make a laser file out of my model
hello mister, make an electric scaffolding mechanism🙏👍
Thank you for sharing, I tried this, but I am trying to create a trapezoidal wing to no avail, just the conversion to sheet metal fails to infer the thickness, when using a square wing it works fine; any idea, suggestion how to make it work with a trapezoidal wing?
It's finicky, I've had that happen a number of times. Ensure the body isn't connected on the back side, and you give a large and constant bend radius on both sides of the wing profile. Perhaps from the square wing try to slowly alter the shape to get closer to the trapezoidal profile until it breaks.
Why not build in balsa? Do you really prefer the low poly look and feel? Not hatin, just curious
cause balsa is heavy and foam is much cheaper and easier to work with.
I've never built a full balsa plane (only wings). From my experience balsa planes take much longer to fabricate and assemble, so I've stuck with foam for the majority of my projects.
@@lskaling Give it a try. It's a rewarding experience

Insightful and incredible, a RUclips hall of fame video for all time
Very well explained and created! Applauds to you!
Pretty cool. Thanks for sharing.
this has been the single most helpful video i’ve come across in literal years. thank you so much
Real

i wish i understood this LMAO, id love to print out decent plans that i made myself
avairable multi sto ? result is a=xxxx b=xxxx c=xxxx i want save sto a,b,c..... this is avairable?
Perfect! To the point!!!
*Promosm* 🌷
thank you so much!
Thank you!
This video was amazing! I wanted to ask what foam are you using? And do you mind posting the sheet metal rule?
I'm using Flight Test foam, but any craft foam sheet would work just as well. Mine was 5mm. The material is flexible enough that the sheet metal rule isn't super important (just setting it to aluminum would work), but if you want to be precise the K factor would be close to 1 since the foam compresses much more than it stretches when bent. Thanks for your feedback!
Thank you very much. This was driving me crazy...lol
Great. Can I contact your team or the person who designed the piece?
I was looking for this so long. RUclips’s algorithm is worst not recommending this amazing video.
dope
Amazing! Just what I was looking for
Beats go so hard
fire
That was epic
