Can't understand how people come in here and criticise the quality of video, mics, and stupid comment's about this and that. I think you guys do a great job! Nice to see people who are enthusiastic and knowledgeable about what they do. Thanks and keep 'em coming.
Fully agree with you. Excellent quality IMO. Very easy to listen to and easy to watch. I don't fly myself but just enjoy seeing you guys enjoy what you both do. Please keep it up.
I made a wing after the portions of a zagi and was very impressed with the flight caracteristics, like you say "flies like it's on rails". But there are some manuvers that a wing just isn't meant for. It's neat to see you have done that and I'm glad you did. Keep up the good work.
I fly paper planes and this actually spoke to me a lot. I was able to use knowledge from my field to fugue out exactly what was happening with your plane. And some concepts, like the air brake, I've built and studied in testing. In essence, origami paper planes are flying wings which makes my skillset an almost direct translation. So in the future, if I ever get into rc/small scare powered flight, I'll start with wings. Thank you for this.
it's worth a shot! RC stuff has become amazingly cheap in the last few years. i recently got into making planes from depron, after flying toy drones for a while. my first test build was based on the paper airplane from the old DOS game glider. :D look for model airplane receiver boards. receiver, 2 servos and speed controller in one
@cafediablo30 My initial thought is two major problems - CG and Torque. Even if you get the CG right, the torque from that big motor is going to cause issues. Delta style wings need nose weight. If your CG is too far back, it's going to keep looping like that. Extending the heavy motor further back is just asking for trouble. CG is crucial! 90% of the time poor flight is due to an unbalanced plane. I hope this helps. -Chad
What you may not realize is that the elevator is the primary means of turning an aircraft. You start with the ailerons to initiate the bank, then you add elevator to actually turn the aircraft, when the wings are banked, the vertical axis is tilted, so up elevator not only keeps the nose up, but also turns the plane, then the rudder is used to coordinate the turn, to keep the tail in line with the rest of the aircraft.
placing the flaps on the inner side of the winglets, propping up inwards, will have minimal impact on the arodynamics, and a whole lot of bite. i can imagine, possibly enough to allow "spins" with little change of trajectory, if you exploit them just right. when the wing starts to turn, the flaps are turned right into the wind, and will propably even pull it sideways and into the turn a bit. i'll report back once i have results. ;)
+Paul Randall “Randy” Hicks ..........Yaaawww all...are so cool. That is our Arkansas opinion. Yaw-all...is plural for you all. Yaw-all means... "All you all."
its not because the motor chops up te air... its becuse the rudder is at the centre of rotation and has no leverage. when you put the rudder in front of the plane, it turns the opposite direction as behind the plane, when it is in the middle, it does nothing ata ll =P
^Yes, The rudder's job is to push sideways, then the distance between the rudder and the plane's center of gravity/center of drag acts as a lever to translate that sideways force into a moment about the CG/CD. With so little distance, you'll get a strafing motion at best, rather than rotation.
You need to increase the length of the lever by moving the control surface further away from the CG. There's three ways to do this. Move them aft = conventinal tail rudder. Move them out to the wing tips = flying wing. Move them forward = ?(could be fun).
There's a reason rudders and elevators are so far behind the CG on conventional planes, it's to act like a lever and torque the plane in the right direction.
I think the biggest factor in the first two methods not working is that the effort was too close to the pivot point. Therefore moving the rudders out to the wing tips would be better, but stil not ideal since it would be applying more sideways motion than yaw. So I think your solution using drag would still give much better performance than conventional rudders in the same positions. I hope that's useful to someone :)
the centre mounted pair of fins and rudders might have been the best option but the tip fins were cancelling out the yaw forces from the small rudders.. you need to cut off most of the tip fins... and reduce slightly the size of the central fins.. for better results
+DIY_glenn Look at the Flyzone Hadron; thrust-vectored wing with a rudder which has a crazy amount of turning input, and does flatspins like craaaazy. :)
I had a friend that created a flying Coke can. Lit up with LED's and flew it at nite. It was so cool. It also rotated in flight. The flight controls inside were fixed. He was the same guy that had the first flying boat that everyone copied.
Flying wings use a scissor style speedbrake on the outer wing to turn in a yaw motion. By creating more drag on the left or right the wing will yaw to the side of more drag.
If Kerbal Space Program taught me anything, it's that the rudder has to be behind or in front of the center of mass/lift if you want orientation change.
Nice video,but why didnt you take the winglets off when you put the 2 rudders on the inside of the wing?They are trying to keep the wing flying straight.Mine flies great.Have a nice day.Great show i always look forward to the next one.
I think you guys should provide links at the end of the video to the next and previous videos... helps me go to those videos (a smoother experience) and you guys get more views. win win =)
good job guys, I look forward to every new show, keep up the good work. I currently have a bixler and a super cub, next i want to try the flying wing, whats ur input on my descision?????
How about putting the rudder in front of the nose with the control surface being the front most? Kind of like a canard wing, but vertical. Maybe one on the top and another on the bottom?
Could work; however having the vertical stabiliser ahead of the CG would cause negative yaw stability... You could have the vertical stabiliser at the back and the rudder at the front ;)
I realize this video is from 4 years ago, but you also could have put a smallish rudder on the front. It is far enough away from the centre of mass/lift
Uhh, that did not work well at all lol. :-) The best way to get proper rudder going is making split-elevons (called duckerons) that create drag to cause yaw movement. ( watch?v=yzl1f-KdQNA ) A rudder also doesn't have to be behind the propellor per say either, it just needs to be a whole lot bigger (as in proportional to the wing surface or it won't have enough authority to cause any rudder effect). It was very cool to see you guys try different designs though, hope to see more of this!! :-)
Correct me if i am wrong but at some point you walk out for the final launch in the background i see a basketball set up where the net is over the grass...Is that how you guys play this game in your part of the country.???...Certainly safe but a slam dunk must be very different...
It would act as a vertical destabilizer. As soon as the plane yaws, the vertical surface infront of the CoG would accelerate the yaw and it would try to spin to face backwards, at which point it would try to flip in the pitch axis and you would have a messy flatspin.
A front rudder would work, just like a canard but in the vertical axis. It would only need to be very small. The best solution is on the winglets though!
@Flite Test - what do you do for the street people who have no rooms no tools and no money? Do you fold a piece of paper a few times and toss your glider into the sky above you?
hi I would like to make a comment. have you ever seen mygeekshow? well If you have you must have seen thrust vectoring o the flying wing. I have actually tried this out on a flying wing and It works. so here's how. 1. combine thrust vectoring with rudder or simpler just put a vertical stabilizer over the prop and the rudder after the prop so you get the most wind 2.now the simple way is done and now the hard but effective way. glue rudder onto motor and glue trust vectoring with rudder.
I'm curious what happened to the other guy in the video? He's no longer In newer videos. Which is probably a good thing. These two aren't meant to work together.
Hi, im new to the hobby and I am building a balsa USA student trainer. It is a large plane with about a 5 foot wongspan and will weigh about 10-16 pounds when completed including electronics. It is nitro but I want to fly it on electric. What motor would you recomend?
Hi, how did you guys make the rudder with only one servo? I'm building a foamie with my club at school and would like to know how to achieve this with only one servo.
this wing has too much vertical stabilization for a rudder control to overcome. for a rudder to have some control it needs to be a larger percentage of your overall vertical stabs.

Rudders need to generate a moment around the CG of the aircraft.
Which doesn't happen when you put the rudders near the center of pressure.
I love that you're willing to post videos about your failures. Learning from our mistakes & all that good stuff.

The world of RC owes Flite Test team....so much. You all have made RC flying .....so "cheap" and simmmmmpppllllleeee. :0)
+Paul Randall “Randy” Hicks ..........Yaaawww all...are so cool. That is our Arkansas opinion. Yaw-all...is plural for you all. Yaw-all means... "All you all."
They can literally do ANYTHING with Foam Core Board!!!!! 😳😎👍👍
Some may not work. But they always fly.
Still miss J. Scott!
Flaps for a wing. AWEsome! Love that idea!
after watching the last 2 videos , you to guys work great toghether.
cant stop watching these vids!
Dammit. Whenever I watch one of your eps, I feel the urge to buy MORE stuff at hobbyking! My wife hates you guys :)
I'm with Ugrdbflasars, lets see some FPV trick or treating! We need David and the tri-copter. Another great episode!

Just want to say that i love the shows and i have seen everyone =) Keep up the good shows. YAW!!! Haha
Why not put a servo on the motor mount, tilt it sideways. I think that would be cool :)
no luck there, guys from mygeekshow tested that theory
+DIY_glenn Look at the Flyzone Hadron; thrust-vectored wing with a rudder which has a crazy amount of turning input, and does flatspins like craaaazy. :)
Hahaha omg I love josh . . (The one with the hat) how he breaks the forth wall with that smirk

Cool video. How about trying the Magnus effect? I think it would be a cool plane.
Another thing you can do is put duckerons on there and that gives yaw control, the only problem is it can be very tricky to set up
Good job boys love your video,thanks for the work too cool .
GREAT EPISODE
Difference, YAW! LOL epic play on words!
Flying wings use a scissor style speedbrake on the outer wing to turn in a yaw motion. By creating more drag on the left or right the wing will yaw to the side of more drag.
Do the joshes also have regular jobs as well as doing flight test ?
LOVE THE SHOW !
Me first I must love your show more than anyone else!
=)
ATB Malc
Try a split flap design or add airbrakes that deploy on one side only. That's how the full scale flying wings work.
you guys should do a video on how to program the transmitter for the rudder on this plane
If Kerbal Space Program taught me anything, it's that the rudder has to be behind or in front of the center of mass/lift if you want orientation change.
"You wanna chuck me"
Who else though Bixler said something a little different? owo
Nice video,but why didnt you take the winglets off when you put the 2 rudders on the inside of the wing?They are trying to keep the wing flying straight.Mine flies great.Have a nice day.Great show i always look forward to the next one.
Great video guy’s
Holy sh#t, a Pontiac Aztek
How 'bout a twin-motor flying wing with differential thrust for rudder control? And maybe put the motors on servos to create a thrust vectoring system
I think you guys should provide links at the end of the video to the next and previous videos... helps me go to those videos (a smoother experience) and you guys get more views. win win =)
I miss these build projects
good job guys, I look forward to every new show, keep up the good work. I currently have a bixler and a super cub, next i want to try the flying wing, whats ur input on my descision?????
i feel like a pioneer ive already tried this last summer with a delta wing flew well however it wouldn't knife-edge at all. i had fun tho!
How about putting the rudder in front of the nose with the control surface being the front most? Kind of like a canard wing, but vertical. Maybe one on the top and another on the bottom?
Could work; however having the vertical stabiliser ahead of the CG would cause negative yaw stability... You could have the vertical stabiliser at the back and the rudder at the front ;)
Wow... This is awesome... However.... if only you had made the rudder control surface just a little(a lot) bigger :D
Where do you guys get your swifts i really want one! great vids guys!!!!
Difference-yall ! yah ? yah... yall !
I made fronterons on a wing, it did work !
btw, I don't expect you to see into the camera while you're flying Josh...
Can you tell us how you programmed the rudders ... ive been tinkering with this on my wing.. we even tried vectored thrust.. no beueno LOL but fun!
Even Rocky had a montage!
Every time I see this video as a suggestion after a video it says "udders on wings" :D
And every time I get disappointed.
Great video as usual, but WHAT happened to Josh B's finger at 3:52?? Its totally black!
If you guys did it fpv, you would notice the difference much more that viewing it from the ground.
what about adding two mig-style air brakes-- one on each end of the wing. do you think that would cause a wing stall or something?
What if you would just rotating the motor? I think that could be a solution!
skinny-pants, you nailed its buddy :)
I realize this video is from 4 years ago, but you also could have put a smallish rudder on the front. It is far enough away from the centre of mass/lift
Rudder canard?
What is that helicopter in the background?? It looks awesome!
Uhh, that did not work well at all lol. :-)

7:04 who owns the Jaguar in the drive way?! I own one myself :D can't believe i spotted that!
ha, I was trying it myself after remembering the ooooold rigid hang gliders that used exaclty the same method for turning.
Haha, in Turnigy 9X it's called "snoproll"
Snopp in Swedish is something else.
Can't believe this video is 9 years old
what if you put wing gates on it? like the airbus winglets
Should do some halloWEEN things. (FPV Trick or treat)
Heres an idea, just add a single rudder in front of the nose like a counter balance, then you get the torquing needed to shift the craft. Plz reply!
That would probably make it pretty unstable.
Interesting!
My Parkzone stryker f-27q has rudders and i like it :-)
It would make it horrifically unstable to fly, and unless you have really strong servo's it'll reach the rudder one way, at any speed
@bobmaxiao No :)
Flies on rails. I see what you did there.
Can you guys make an aircraft carrier/helicarrier with a nano drone in it that will deploy
Just an idea, if leverage is the main thing that makes a rudder work, why not using the twin fin/rudder with the movable part in the front?
It would act as a vertical destabilizer. As soon as the plane yaws, the vertical surface infront of the CoG would accelerate the yaw and it would try to spin to face backwards, at which point it would try to flip in the pitch axis and you would have a messy flatspin.
A front rudder would work, just like a canard but in the vertical axis. It would only need to be very small. The best solution is on the winglets though!
the swift has kick out rudders like this
coordinated turns
Josh Scott seems to be more knowledgeable about RC now.
@RCT3GOD Yeah, it is from the "big things" video
Thats a nice blue bmw
@Flite Test - what do you do for the street people who have no rooms no tools and no money? Do you fold a piece of paper a few times and toss your glider into the sky above you?
What engine and battery and ESC you have on that plane?
Greetings from Belgium!

i dont think the moment arm is long enough for a rudder to become effective.

Single rudder in the front might give better results.
this wing has too much vertical stabilization for a rudder control to overcome. for a rudder to have some control it needs to be a larger percentage of your overall vertical stabs.
What about putting the motor on a servo controlled pivot?? Left and right.
Derek Wise and because it is that close to the cg, they would've had the same problem as with their "double" rudder in the middle.
Derek Wise and because it is that close to the cg, they would've had the same problem as with their "double" rudder in the middle.
might be a stupid question but what material is the rudders made of ?
3:55 Is Josh's right thumb injured and bleeding or is that just oil or something?
Hi i would like to apply that to my wing but can you give us how you manage to wire and set the tx for that? I am using fs i6x tx.
Can you or have you tried the FPV on this with the rudder mods?
cool i wish my house was next to a flying ''field"
how do you programme differential rudder?
How do you set up your controller to do that? I have a DX6i and I am trying to do something similar!
