I’m only 5 mins in, but I have to say the speed at which you are launching it from your hands is much much much faster than the speed a full size manned version will leave the ramp, you need to slow the launch speed of the model dramatically to get anywhere near how the full size version will behave.
agreed, and even adding the electronics seems wrong. They should basically be pushing it off the edge of a table and nothing else.
Things scale up different though, double the size, four times the lift area, so having more speed to compensate for the lack of lift at small scale is valid, isn't it?
Basically needs a drop test
Or a sabot design to accelerate the pilot as he leaves the edge of the platform
I would think that the speed is relative to the size.
BOB!!!!!!!!!! I miss watching him in the videos. I laughed so hard at the string plane. The spinning until he dropped had me in tears. MORE BOB MORE BOB MORE BOB!!!!!!!
the release platform is the most important thing something that can get the aircraft moving at the right speed. I would suggest once you get your idea for flight (aircraft) that you can work on this release system as well because it'll make the aircraft fly farther and faster.
FLUGTAG!!! I can not WAIT to see y’all compete! Between this project and the Land Speeder, I don’t know which one I’m most excited about seeing the final product!
This is awesome! I love flugtag! You guys should try to build a working rc cropduster to sprinkle flowers now that it's finally warming up
Josh always seems so relaxed. He's like always using his inside voice. It's a nice change from how most of youtube is basically always yelling and layering in explosion noises.
I would like to thank you Josh, for another thought-provoking model aircraft show. On that note: I was just wondering, based on the aircraft design in this particular segment, have you ever thought about doing an event that will mirror one of my favorite childhood movies that was called “Those Magnificent Men In Their Flying Machines?
Love the idea brother! I love that show too :-)
JB
great job guys love your vids good luck!!!
Thankyou for the update on the ez system, it is the perfect system for my micro balsa models I build, can't wait!
I love the EZ canard!
You guys need to come to the UK for the Brighton Birdman competition, happens every year, You jump off the Pier and in the air or English Channel. Try using split bamboo for strengthening
Is an awesome model Josh and guys. Good job it was an amazing video. Keep it up🎉
Here in Melbourne Australia, we call it "The Birdman Rally" and happens at Moomba each year in March and has been happening since 1976.
Aw, man was just in Melbourne during Moomba but somehow missed this! Sounds Awesome! Headed there again tonight actually 😁
It would be nice to see more designs like this for indoor flying.
Awesome.
Thanks
I think the best approach is to briefly dive right away and then try to run your distance out in ground effect.
Yep if you gain enough air speed and have enough elevator authority it should fly a pretty decent distance!!!
@@EJ-74 if you can make your stall speed slower than the speed you can run it off the ramp, then your glide ratio is all that matters. higher glide ratio would equal longer flight. Porpoising would lead to increased drag and decreased efficiency, shortening the overall potential flight based on the energy you get from the drop and the push.
@@friendlyfire01 Yep trust me I understand I build and design RC planes, I very rarely fly my factory models anymore lol It's just something about flying your own build that makes it much more satisfying hehe I see exactly what you are saying but they do not get a lot of thrust - push lol so what I'm saying in reference to the original comment is they need to gain as much air speed as possible then hope to have enough elevator authority to hold it in ground effect long as possible!
@@myotherusername9224 I fly everyday the weather allows and I build and design my own planes so I know how to stretch out a glide far as possible etc, not saying I'm a great pilot but I know the basics and with out thrust you must gain air speed to build up enough lift to sustain flight and that's a fact. lol
The efficiency gains are questionable. Ground effect reduces your induced drag at the cost of increasing parasitic drag due to turbulence. This is compounded by the fact that your initial speed will be very high from the dive, again reducing induced drag and increasing parasitic drag. And of course this requires precision altitude control that is hard to pull off on gliders at the edge of stall.
Make the canard wing a fully flying (movable) elevator surface. Trailing edge control surfaces won't work at such low speeds.
Additionally, when the front of the glider inevitably drops towards the water, a flying elevator would keep more attached air flow in the dive and better lift to pull out.
Cool video.
I've never touched an RC plane, but I find you guys fascinating and immensely entertaining.
I could watch this all day just because it is so cool. Keep up the good work.
Hi Josh, it looks good when it’s under power but the descents all seemed to be under reduced power, how does it glide with power fully off.
Set it on a shelf approximately the scale height of the barge. Then give I light push off, and see how it glides.
An amazing vid as always!
You guys should make a vtol aircraft maybe
-v-22
-dornier do-31
-Yak-141
-Av-8 harrier
-f-35B
Are few examples , really want y’all to make a vtol jet or smth
And again very cool vid!
Let's Go 🔥
I hope we can some crazy challenge with those Eflite Slow Sticks!
Go for Santos Dumont's 14bis in foamboard with box-kite canard . . . softer for Steph to land on/through : )
oh man you guys have all the fun! I just want FT peeps to know - it is a lifegoal of mine to be a Flugtag Pilot one day!
it's an overrated experience
Love the CMMG Mutant shirt!
IF you look at the record for RED BULL FLUGTAG which was a B17 bomber. Notice how he does not have control surfaces on the elevator. THE ENTIRE ELEVATOR MOVES, much like a fighter does. I THINK THIS IS THE KEY. because the airspeed is SOOOO slow you need to be able to make BIG corrections. here is how i would attempt the world record.
1. fall a little to gain speed.
2. yank the MASSIVE elevator full back for a second to flatten out.
3. coast slightly above water with the speed you gained from step 1.
if you look at all the failed designs they purely just dont have enough speed to get the world record glide. BUT THAT B17 CRUSHED THE RECORD TO PIECES.
The addition of a Unobtanium flux capacitor would greatly aid in stability and endurance. That or a big rubber band powering a high ratio gear driven prop. Awesome design. i will get one when its finalized.
I feel like a larger surface area, fairly deep dihedral styrofoam wing you hang under superman style, is really the best configuration. Quick release hang glider harness, to escape drowning? 😄
Let's go go go go go go go
looking super.. maybe next iteration would be materials.. reminds me of kite surfing
You guys do realize that Langley’s effort were for naught! I can’t wait to see what this year’s aircraft looks like. That flat plate model was flying great. Last years was great looking also. Loved the pre-war markings on it! Good luck with this years bird. Again, can’t wait to see it. Bring us along for the ride.
considering glide ratio how tall of a launch cart is allowed ?
First to comment! Good job you guys are doing.
Writing from Lagos, Nigeria!
Try making a space shuttle!
Now the supply is coming back. Will you have the bundle that had the ft freighter and the ez jets? Been wanting to get that for my grandson
Bundles Will definitely be back as soon as they arrive. :)
Try to use the grund efect i think its gonna make it go further and its fun
A good resource if found, would be videos of the German clubs glider experiments from in between the world wars when they were banned from powered flights. I remember seeing them half a century ago, I wonder if the footage still exists.
You guy's have a pond there at the Golf Course. I would consider mocking up Red Bull's launch platform, and real world test your builds prior to Flugtag. It doesn't even have to be full height as long as you record your tests you can calculate full height trajectory.
Could you please do a ring wing like the one in (Found And Explained ring wing) and all of the aircraft in that video as R.C planes.
Just curious what if you created a launching platform that activated a trebuchet action creating more speed at launch?
Minimum weight. Mimic the launch bardge and then work on the glide.
I was just going back to old videos, to get my nostalgia fix (When David, Peter, Alex were regulars) and watched the Pokemon flugtag episode yesterday! What are the chances?!
Hey is that new twin-boom(?) Flerken still coming out end of March? I've been checking the website but don't see it yet.
It will be coming out in April. We wanted to wait and test it off of water to make sure it’s truly all-terrain. Cold weather or bad weather sadly prevented us from getting him to do the final test so we had to push it back.
I'm waiting for the slow ultra stick review
Can you please tell me what electronics you put on the small test model as i like building small planes but can’t find small and light electronics. Thanks
The electronics are the FT EZ power pack. It will be back in stock around the end of April. :)
If there is someone to beat the MIT record .. is you guys! All the best of luck! ... I got here b4 the kk32 was born, and love your content
What’s hanging in that room
Anakins pods from his pod racer? What it looks like from what I see
can you guys make a p 39 ?
try a ground effect plane.
i would like to see you make a north American x 15, pls 🙂
Considering that you have to push the plane to get it to fly you should probably be building a airplane that you can get to fly by pushing it and master it on flat ground
I’m not into designing but if you join another flag tag maybe try one that relies on the drop to launch the plane. I mean when the plane is lunched off the edge the bottom wheels drop. Maybe use the drop of the wheels from gravity to launch the plane?
Try having the front wing higher than the back, not much, maybe 1/4 to 1/2 inch. Then try a model of your launch cart to try takeoffs from a desk, to simulate the barge launches.
Love a good design challenge, especially now as I learn about airplane design in greater detail.
Based off the first design, since both wings were cambered airfoils you had a phenomenon where the rear wing was in the wake of the fore wing. At low angles of attack that makes the rear wing lift even more, causing a pitch down moment while the front wing looses lift. Its kinda why going to flat plate wings helped out cause zero camber airfoils (plates or symmetrical) produce little or no wake, so the wings could both stall at relatively similar angles of attacks. A similar result could have been achieved with either symmetrical airfoils, lengthening the distance between the wings, raising the height of the rear wing, or giving the forward wing more incidence to the fuselage. Or also of course, fitting the fore wing with an elevator.
I competed at flugtag last year in Toronto. Our plane flew about 100m downrange before controlled descent into the water.
Bill Kong why are you lying? The world record flugtag is 78.5m. no one has come close to 100m. What was your team name so I can go watch the video?
@@joshua_J Red bull posted the video on their shorts. It has about 70 million views. They chose not to count us as the official record. You'll understand why when you see.
100m is a pretty conservative guess. We were about to fly outside the designated flight area and they instructed our pilot to put it down immediately.
@@appa609 can you post a link to it. I would love to see it and I will absolutely apologize to you. I feel horrible now. I follow flugtag and thought I knew what the record was.
@@appa609 hey I did a little research and found your plane. I absolutely understand why they didn't count it you could have went for miles. I'm sorry called you out I assumed you followed the rules and that's my bad. Best of luck next year but a little advice, keep a damn pilot in it. Lol
Make a flying tank next year. Its not a good idea, but its funny
How many scuare foot wing area is the limit in that event?. Biplane will be the solution .
Good luck guys, and remember, failure is an option, especially if it's spectacular, and funny.
Is there a length limit?
How about making it so long that it can be continuously pushed from the back until it contacts the water?
Can you tow it from the front and have all the towers jump off the front of the ramp while still towing the plane so that you get to use all that extra energy from their falling mass used in the launch?
You kept saying incidence but It felt like u were talking about dihederal....I thought incidence referred to basically the sweep of the centerline of the wing forward or aft from root to wingtip. Or maybe I just couldn't see incidence on the wing.....just making sure I am not using wrong terms
if the wheels of the cart wind a propeller, or a slingshot, like an aircraft carrier, would that be legal?
You need to be under the plane. Bottom heavy = stability
vortex generators?
Would it be legal to implement a design where the front of the craft leaves the deck, falls and generates force that catapults/levers the trailing wing and pilot with extra speed and launch height?
I'm sure I've seen something similar, where the 'crew' jumped off the platform holding a rope which was rigged to catapult the aircraft off the edge.
that's against the current design rules, your application would be rejected when they look at your drawings. if you kept it a secret they would scrub you off the manifest 'day of' and not let you launch
no
Have you guys made an f-14?
What about a v tail design?
can you make the F14 with the moving Dorito wings
You must ALSO design the aircraft with smaller forward wings---like a canard---and find the CG to work.
always wondered if it scales up at a constant. I would think that the weight vs the air mass would change the bigger it gets making it less efficient.
Nice thing is that the larger you go, the light of the wing loading, but also the higher the drag. If it flies slow as a small airplane, typically it’ll fly even slower has a large one. That’s why we love building small proof of concepts. They rarely ever bite us when we go big. :)
It needs a Lego Man riding it!
Just don't forget to move center of mass to the back a little this time and will be ok :)
With a flat wing, it flies like a nutball!
wut
"flies like a *nutball* " ? what does that mean
The key is to make some type of gravity system to help catapult the aircraft off the deck at a higher "airspeed" like a aircraft carrier. 👍
that's against the design rules, your application would be rejected when they look at your drawings. if you kept it a secret they would scrub you off the manifest 'day of' and not let you launch
So you know there is a online C.G. calculator out there for RC canards, it also works for full sized aircraft. Using it will remove some of the guess work.
Definitely agree. We love to keep it simple and fun. No doubt that will come to play as we get closer to the competition.
E- filte ultra stick! do video
You should have a contest were the slowest aircraft wins. 5 circuits of the field, *LAST* one over the finish line is the winner.
Wow, saw this 3 minutes after posting.
If I were doin' it, rather than your 'Langley-esque' design, I would look at the Wrights' pre-1903 biplane gliders as first choice. They were extensively test-proven, and evolved directly into the powered Flyer of 1903. And lookit how Langley's fullscale turned out.
Great design ideas and fun for sure, but as I understand it, your plane wil have to get to flying speed with a very anemic, short foot launch, so isn't designing it for power counterproductive?🙂
The power is simply to help us get a Stadium Glide. Plus it is a ton of fun. When we take it up the height and cut the throttle, we can observe how are Glide and the speed. That will be the natural glideslope speed that we will need to be able to get too. As we get bigger, we will bring more of the science of the launch into it :-)
tripple wing....
The key is Reynolds numbers. The Model's numbers are not the same as the full scale. For launching, don't push: pull in the opposite direction of the end of the ramp, using a cable and turn-around, like the towline class of RC glider models do. Then your propulsion team doesn't worry about running off the end of the ramp at all and can give maximum effort the entire way.
foam flying wing
make a smaller canard in the front
Shouldn't the center of gravity should be adjusted to the pilots weight positioned on the craft?
You need to increase your takeoff speed to fly further. Just watched a video which they used 6 foot diameter wheels to get a greater launch speed
John Overstreet should field a competing team, Flight Crew, Peter Sripol, Rotor Riot too!
I think you should make a airplane carrier show aircraft carrier so you can lay an airplanes on it I'm just saying I think it will be cool josh
So the best ones drop off the edge and get some airspeed before leveling off and using the water for the ground effect to get maximum distance... Can I say practicing with something with a motor is not as effective as practicing with a glider which will have the correct flight characteristics.
but your glider is a good one 😀
"What!? a flippin' skit?"--- Napoleon
Flugtag u want more height at launch and to be able to create lift from the fall....if you scaled it up from testing it won't be launching that fast at full scale... almost like you woukd wanna drop it moving slightly forward to be same as a huge plane moving at 1 mph off the ship....even a gentle toss like that is way more momentum than it will have full scale....but if you build a nice tall cart on wheels like your first flug tag but like as tall as you can go.. the final design will gain momentum I the fall and maybe have front wing pivot or pulley system for both to pivot on fall after it gains momentum....it could b amazing.....remember that one like 2 urs ago that launched off like 12 foot tall cart and sent current record....seems the more height u have to build momentum on fall and transition it to forward momentum works best....from observation standpoint...naturally harder to do in real life from scratch
You really need to simulate the launch attitude more accurately. If you look at every launch you did, you provided a positive AOA and a pretty firm shove for each launch. Build a scale launch platform which will precisely duplicate the launch AOA and you will see huge differences in performance.
I have been building planes off the ft ez board for over a year now, and I'd recommend using some styrofoam plates to lighten up the design, I've seen much more success with them
whats the ft ez board
how would styrofoam plates work, I'm not visualizing this idea
the greatest Flugtag design I have ever seen was one that had a flywheel built into the launch vehicle that was geared up and attatched to a sling mechanism that launched the plane forward at great velocity as it released
also quick note abut Flutag, there was a similar event hosted by a dutch organisation back before Red Bull started their Flutag, does anyone know what it was called?
It was called "ter land, ter zee en in de lucht" it was a program with different themes, only one of which was with planes, all were major fun though 😊
Flutag: where it's ok to be more excited to see them fail.
For such a short flight, you don't need to bother with ensuring the front wing stalls first. The primary reason you would do that is for safety...to avoid a deep stall that is unrecoverable. Don't hamstring your design when it is for a
Your secret is safe with me..I won't tell a soul.
