Scale it up and FPV it!
Isaac Lyons I agree!!!
Do you mean: Try wingsuit and attach a GoPro to his head?
NERF870525, good idea!
Isaac Lyons i
Finally part 2 arrives. Great videos. Please scale it up. The last drop really proved that it could work.
3d printing is a super heavy method for constructing something like this. In your last video when you said the weight to surface area scaled properly you forgot how air doesnt scale. To get similar results to an actual wingsuit man you would need your model to be significantly lighter than what would be proportional to its height.
Thats interesting, Ive never heard of that. I am simply speaking from the many places I have observed this in my experience with rc. Theory is fun but what really matters is how it actually works in practice. (You cant deny that making it lighter would give it a better glide slope, thats all im really saying here)
Sorry Dave your'e wrong scaled down aircraft cannot weigh the scale weight of the full size aircraft and be able to fly. For example the Extra 300l aerobatic monoplane has a max gross takeoff weight of 2095lbs if you were to scale it to 1/4 scale and scale its weight by 1/4 the resulting scale model would weigh 524lbs. Quarter scale Extra 300's are common place in the radio control hobby, and they have a max gross takeoff weight of about 16lbs. The difference in weight has to do with amount of air molecules passing over a given airfoil known as Reynolds number. More info can be found here www.nasa.gov/pdf/601262main_ModelingFlight-ebook.pdf check out pages 12 and 13
It's also relevant in scaling models as aerodynamic performance varies drastically with Reynolds numbers due to differing levels of influence by viscosity, However, a factor I don't think Thomas has considered is linear vs quadratic vs ternary relations. If you half the wingspan you divide the wing area by four and decrease volume by a factor of 8. So, assuming a quarter scale wingspan extra 300l could generate the same lift per wing area as the "real deal" its take off weight would be 130lbs, still a far cry from the real value of 16lbs but closer (still miles off though).
You would think tom would know all about that stuff as he is taking courses in aeronautics
@@thomassouthern23 1/4th the scale does not equal 1/4th the weight, as the aircraft would 1/4 on all 3 axis.
The actual weight would therefore be at below 33 pounds.
"That wasn't flying! That was ...falling with style!"
Scale it up! I think maybe going to a wood and cloth setup instead of plastic would go a long ways. Maybe a 1 foot or so wing span? Good job man!
Plastic may be better for strength over wood, in a cloth and plastic design.
I don't disagree with that at all. I'm hoping that he can make it a shape and size that doesn't allow for TOO rapidly of a decent, like a kite almost.
Jeremy Gillespie as above mods but possibly use shower curtain material for wings, light and strong. ...also waterproof !!
its not 1918 its 2018
Why not full scale?
Fantastic! You looked ecstatic, and justifiably so. That qualifies as a resounding success in my book.
Looking forward to your next iterations.
"The easiest landing I never did"....classic.
Falling with style! It didn't tumble straight down but covered some ground with control. Great fun to watch. Congrats!
That was really cool. That's what I like about your channel you try things that others say will never work. I can't wait to see the scaled up version.
Great!
Thanks Tom. You made me smile again. Was watching you long time ago in your T-Rex 700 time. Glad I found you again, great video's Tom. Keep up the good work.
(Sorry, English is not my native language)
GOOD JOB TOM --- IF YOU DON'T TRY, YOU DON'T KNOW. YOUR EFFORT HERE ENABLES MANY KIDS AND ADULTS TO KEEP THEIR PASSION OF EXPERIMENTING ALIVE!!!
Wow, that last jump looked really great! This looks like it’ll be feasible to improve flight characteristics! Thank you for doing this project, it’s something I’ve wanted to do for a couple years now but I’ve still yet to get a 3D printer...I have so many projects I’d love to do. So thank you for doing this series 🙏
Me: "Chickens can fly!!!" Science: "It's more a controlled fall actually...." Me: "Shudup..."
You're told chickens can't fly in school then one launches itself at you..
Apart from seeing the dummy glide, (success!), the most thrilling segment of the video was when Tom suspended himself in midair long enough to click his heels together. More of THAT Tom!
Well done guys!.. The third flight was a winner :-) Nice to see Brett in there as well ;-)
Great work Tom! I really enjoyed seeing this one.
Your videos are getting better and better man, it was hilarious and it actually kinda worked! I’m getting a big fan of this channel!
Great job Tom I am having fun watching your progress!!
Good work! That was hilarious!
I get so genuinely excited every time you upload man, thanks for the great content
I've been checking your channel daily for this!
Thanks Tom, another great video and project.
It actually kinda worked awesome job
Nice job Tom!
Good thing's come to those who persevere, good stuff tom. You have to go full scale and fpv it off a base jump high point lol.
This kid never ceases to amaze me. Well done! Again!
Completely awesome! Nice project!
Great to see "Brent Collins" there to assist ... LMAO Love ya work Tom.
Dude that would b so cool to see a bigger one !
DUUDDDEE!!! Major tips: 1. The center of mass and gravity of a human is ruffly between the shoulders and the hip. 2. You should try making a " Distance Wingsuit . This is basically a Wingsuit where the arm wings are conected to the legs. 3. Arms turn the wingsuit left to right while the legs control pitch. IE. The arms don't control decent. 4. The arms, legs, and body all have the same length. HOPE THIS IS HELPFUL. Also the arms are too short and angled too far back.
Enrique Medina it’s closer to the bottom of your ribs I’d say
Nice work, I was impressed on how well it was falling, I thought it was just going to tumble all the way down. Congrats!
jayrothwell how dit you see it a day ago?
Patreon.
Boaz Mulder yes, patreon gets early access
Very well done!
Fantastic video!!! So funny!!
Congrats Tom! Don't quit amigo...you own this
fantastic episodes!
Another good one Tom! What next? Can't wait😎
Nice job! Love that drone to drone video.
Oh my gosh thats why I love this channel
worked very good nice to see
The video quality on that Mavic is really astounding.
This was such as smart thing to do!
That was awesome! agree to scale up a bit for longer glide flight. Tom you are the first who did this scale!!! See you in the next video buddy;)
I like that you had an extra hand with filming this time. Maybe you can make a mini indoor skydiving wind tunnel to refine your design. A leaf blower might have enough power.
Did u stabilise the footage around the wingsuit near the beginning in post?
I'm wondering why you use a 3d printed hard surface for the wings instead of the tissue like used in the parachute. There is a functional reason??
Man... Forget about the wingsuit. That quadcopter you build is AWESOME! 😀
Love ur shit. need too hurry along though! Need to see the next episode of this voyage!
can a rotation of the legs also be used for steering?
One thing is on the (do I call it a full scale jump suit?) there is fabric from about mid bicep connected to the leg and attached to the side of the flyer to make a more flying squirrel look. Would it help to attach that bit to your flight suit guy? Just a thought
Great video bud
great project and good results, hope seeing it upscaled for more glideing time. nevertheless great work and brilliant idea to built a rc wingsuit.
well done. Tom, you've got tools, resources, wit, and opportunity. If I had those things at your age! Well, let's say this: Challenge yourself. Think outside the box. Do what hasn't been done. Engineering degree, yes, get one. More importantly, look beyond. New inspirations tend to be accidental, and discoveries made whilst endeavoring to do something ordinary. Have fun. Avoid what happened to me. Don't let anyone hold you back.
Good job! Do you think your wing suit guy would glide better if the wing and tail area were some sort of cloth like rip stop nylon?
I would be curious if the increased drag would generate more lift ? keep up the good work. cheers from the USA
We really need a follow up for this project! Don't give up on it!
Super job
Great job, amazing
There was a distinct glide ratio, maybe not as large as you would have liked, but never-the-less, it was there!! I say that was a real success!!
I have been waiting for this
That was very clever
good work!
What if you use nylon for the wings instead of PLA?
That was awesome!!
I'm in Australia, super late and random times I get notified for your videos but until Game of Thrones come back on you are my highlight. Cheers mate
Lee Harrison .
Hell yeah!!! You may have just pioneered a new branch of rc hobby sports
Good work.
Very fun, GG !
That is really cool I hope you will offer the build files in a scaled up version thanks .
I suspect it needs some forward momentum (i.e. don't drop from a hover or virtual hover), and weight does not scale like dimensions do, so it probably needs to be as light as possible.
You sir are a genius
Very interesting and enjoyable....
have you tried 3d printing parts for your model helicopter? I have one about 40cm long and have never been able to fly it properly. i have attempted and had to repair the rotor assembly many times. which is quite costly, since a tiny piece of plastic is apparently worth $15. im thinking it would be cheaper to model them and get them 3d printed at a high resolution.
how much weaker is the 3d printed plastic along the 'grain'?
Could you replace the wing part of the suit with actual cloth ? look cooler and possibly fly better?
wing suits generally have a 3:1 glide ratio. so it kinda does look like falling
Great video!!! FPV would be pretty awesome...
Liked the vid instantly
yep, 50% larger wings and she'll glide like a ripper! well done nice work!
Nice vid. But isn't the chute a bit small in size?
So you know how when u kick a ball and make it spin it will fly off to the side? Make something fly using that effect.
The front wings on a wingsuit go all the way back and connect to the feet on the outside of the legs. I feel like that would've helped get more stable lift.
It's flight characteristics are somewhere between the Space Shuttle and a cinder block.
i feel you should try making a skeletal frame with the front end comparatively heavier, then use moving louvers instead of the cloth to glide rather than a solid 3d print. and also when you drop it move the drone a bit forward and release so it gets that horizontal push because a person jumps of the aircraft so there is a horizontal movement to glide.
Tom, thanks for your pure engeneering ideas! You can try "Rogallo wing parashute" to control flight direction after deployment (easy to conntect parashute contol line to hands-wings :) It was tested by NASA for Apollo
Is that based on the simple planes sky diver?
Awesome
You can make another one but the wings instead of being of plastic you can use fabric and also for the legs part that would probably make it lighter, but out of that good job I was waiting for this video....
What drone do you have?
Put a pivot controlled with a servo between the legs and the torso.. I know they use there legs to control yaw and as a part of other control in conjunction with their arms..
that was cool!!!
Take it to one of those indoor skydiving places and see if they will let you fine-tune the controls in their wind tunnel!
super....cool...great job..i think your rite with going bigger...great joooooobbbbbbbb........
Yes! Video!
So that's really cool. It would be cool to see someone make a rc FPV paraglider
You can abort the DJI return to home by switching the mode switch to manual and back to GPS mode.
So cool :)
edit: forgot to add, awesome thumbnail!
think it just needs more altitude so it can gain the forward movement it needs to glide
Where is this park?
Nice video
Having rigged a few things dropped from models (and rockets too) I would say to put a short piece of bungee or elastic in between your chutes and the load, to soften the opening shock.
Brilliant. Greetings from (29° C) Sydney Australia.
That was great . I would like to see you build a bigger one , which will glide better .......try and do a self unfolding section between the hand and ankle on each side . I'm not sure how well that would work . but I think it's worth investigating .........see you in your next one ......... Cheers
I think if you build a bigger one, you should use a printed gear set for the servos to use more throw but less actual movement of the arms ("wings"). That way the larger surface and stress can be easier on the servo and partially carried by the frame. Great job on the little guy though, it did better than i was expecting :)
