hey, I've been flying remote control planes, mostly gliders since I was about 14 years old and you did a great job on that man it flew obviously with most of the stuff we build from the ground up it's going to take a little bit of refining but damn good job sir

Spray cooking oil on the table surface first. will help in cleanup

I watched this for the dialogue. Best I've heard on YT

Nice clean wings good work, man.

Beautiful. Just beautiful. Thank you
valderja
Impressive work. Very clever idea.
Wayne Shephard
Good on you for trying something different, thinking differently, it gives you a nice smooth surface immediately, not a bad idea.
Jonathan Moore
I have used this method for creating "nerf" footballs. Great job. My wallet thanks you.
Matti Rissanen
Damn. I thought I read "exploding foam". Well...why not?
RCHeliJet
Fantastic Work and it Fly very well :)

@6:03 I can envision making a mini ultra with that wing shape...Awesome
99% Perspiration
great job. if you want stronger versions, use split coroplast for the skins. very strong and stiff.
Himanshu Nimbalkar
or you can hot wire the wing
george orwell
cool dude. loved the vid
POPS
you clever man!

Always wanted to experiment with expanding foam to make a wing. It always seemed so durable and like a great way to make a custom airfoil. Since it's so heavy I never gave it a shot. I never thought about making a slope glider...the weight is perfect to cut through heavy winds. Great demonstration of how it can be done!

Nice place to fly !

you could use offcuts for model railway scenery 😉

Sweet idea. Always cool to see people build something themselves versus buying it at a store.
David basi
too expensive nop?

I think it would have been better to use mix your own foam and have the mould on end then pore in the foam from the top it is easy to add to if you think you have not mixed enough and then just pore the extra in, I have used it for several projects I even repaired my rudder on my 40 foot sail boat after it split open by cleaning it out and taping up the rear then added the foam from the top I just watched it expand then when the expansion was slowing down just mixed more and added it this i did 4 times until it was full then re fibre glassed the back end and top and it was stronger than when it was new, I also built a new freezer using plastic board and filled the outside with it it ended up having around 6-8 inches on the base and 4-6 inches on the sides and top it would then freeze in less than 1/2 the time it use to take even though it was the same motor, pump and freezer plates it would pay for its self in the first year in using less power to run the pump than it use to also the pump came on less than half as often compared to what it use to which with it taking half as long to get the temp down and operating less than half as often it was actually only running 1/4 of the time it use to.

This seems like an hugely excessive amount of work compared to hot wire. I can't see an advantage.
JemmetGK
Now that was impressive.  I can see that technique applied to other products, not just R/C flying...

Too much mess 😕 Hot Wire appears to be a better choice.

Like welding without a mask in bright sunlight?

the earth is spinning 1000 mph no need to fly just hover and wait for the spin
cashman156
Great that it flies, but man, lost the will to live after 3mins in! There's got to be easier ways?
KelevraSXT
Try Locktite titefoam. it's more flexible and has a smaller, tighter foam structure. no large pockets of air that could weaken the structure of the wing

Seems like a lot of work...
Famous Internet Guy
neat!
Gordon Freeman
Everything used in this video is expanding xD
Andy
Nice - why not mold a spar right in? That would be a big advantage of this over hot-wire cutting.
Rosario W
I had this idea a few years back but never followed through glad to see some else did AND did it! Nice job
William Hicks
looks like it makes a very strong wing... I like it.
Charles Roberts
From the thumbnail, I thought you were gonna cook a chicken ... I gotta get new glasses lol ;-)
Kamran Ahmad
Awesome... next time I'm out at the bar I want you to be my wingman.

Excellent....
Guy Griffiths
Thanks for the guide I'm making one right now! :-D

This guy must work at an expanding glue factory
Tom Jacobs
I love the look of the selitac :D like a vintage pop rivet plane.

Great use of everyday, easy to get materials. Great build video.

Extremly nice Idea!

Look! A UFO!!!!
tj hoff
is it purely a glider or did it have a propeller
minor0confusion
use clingfilm and hairspray on the mould, fill directly with foam, done
pangrac1
Jeebus what a waste of time, energy and material!!! Simply hotwire profile from XPS or EPS foam and you are done.
jfingerskeys
cool build
Piotr Lenarczyk
Maybe use stretch foil for wing insulation. Have you added some fiber glass to that structure?
juan josé boullosa García
What has been the final weight of the wings without motor and electronica, in empty. saludos
gordontarpley
Really good idea!
EngineerNick
nice one :)

A camera on these wings would give very distorting video. See how quickly it moves up and down..
constantinos schinas
ease out when filling, this foam is called expanding, for a reason.
Solenya. Pickle man Ur gay if ur reading this
Very ingenuity
Hakapik
Stupid idea. White foam block, make a foam cutter from nichrome wire, VERY easy to build. 2 plywood templates the shape of the wing root and tip glued to foam block, cut the wing core and then use 3M spray adhesive to glue outer skin to foam core that you made. Very easy to make as many wings as you want or need in very little time with no mess or screwing around like what you did.
Dave Lee
you know eBay sells these for less than $20
Richard Mcginnis
i bet you that would work for human use-homemade airplane if you could get bigger pieces of that stuff
RC Hammer
I've had great success with expanding foam and cling film! The cling film seems to bond with the expanding foam to make a really strong hard coating, a bit bumpy but awesomely quick for lids/housings etc. Would work well with a mould I'm sure. I lay out the cling film spray foam on, mix it to remove air (and make a denser hard outer layer) then spray foam on top and add a top layer of cling film(with mixed foam as before). It's proper crash proof!

Mow make one with an expanding wing
Dan Jacob
Good job, but he's not really making a wing from expanding foam. He's eliminating the need for internal gussets and profiles for the Selitac folded wing.
Mick Shore
good idea of great video but an awful lot of work for something that cost peanuts to start with, really have to ask a question is it worth all the messing about?
DeltaAssualt
Thats a lot of expanding foam waste, should have made both end sold with holes so you can spray the foam into the mold without wasting the foam.
Ali Ghane
trimming is difficult due to weight. tail would,ve be good

What a mess....

nice job
Visceral
it looks like cyst popping
Transhuman Mercury
What an absolute epic amount of waste.....!
lenny108
nice video, but how do you fill the kerosine into that wing?
Jose Maria Fernandez
Excellent job IkyAlvin, very ingenius. But I have a question, what is "PVA"?. Thanks.
Harley Me
think I'll stick will hot wire cutting...
jorge Nelson felix
😃 Fantástico 😃 👍👍👍👍👍
Jimmy Demello
How strong are these wings compared to EPP? I can make airfoil with 9mm EPP very quickly and by using carbon fiber tubes or fishing pole sections, they become indestructible and still very light.
Moogy Banna Hilstopaflingon
Nice job...!
JAMES TUTTLE
Looks like a truly excessively wasteful way to make a wing. Thanks, But I'll stick with the 'Foamboard' process.
john brown
What is "expanding glue"?

que material metálico é esse que voce usou ???

It's a too expansive way to make a wing

Step1 buy cheap radio control plane on Amazon for 15.00
adam1983ish
It's called expanding foam because it expands. Why did you waste so much foam? That resulted in more work for yourself
jthepickle7
No offence but I sure hope you don't work for Boeing.  Edit.  I hope you work at aircraft design.
dagobb
Nice !
Reefer
Well done great vid very educational, how does the wing go for radio reception? I would imagine all the alloy on the wing surface would play havoc for the Rx, I imagine sloping you don't go so far, but does it interfere on longer distances to your Rx?? I suppose you could use plastic sheeting for the skin and that would solve the Rx problem?
Alonzo Branson
Only thing I don't like about expanding foam is the waste that sometimes results. But, it does fill a cavity quite nicely!
Jerry Newberry
Great way to make a biplane wing.
David Coxon
Nice, but there's a lot of waste.
Tao Jiang
a little bit heavy, please post the foam you used.

He forgot it expands

Nice. 👍
