Man I wish I could have gotten the PID tune better before we started shooting. But the episode was awesome! Christian is a wizard at editing. Looking forward to seeing you guys again and hopefully not in a too distant future
David for the bicopter have you thought about going larger and being able to run a standard servo either with a gear driven system possible even making the booms the pivot point. Also what about a v tail rudder system like that of the osprey.
hi david your design is beautiful but i think its your frame that is making it hard to go backward. i think when you go back a lot of drag is being created at the nose and since the nose is tilted down when going backward it is acting like the control surface of airplane and is pushing the nose up and the fc is trying to auto level it and i think that is the issue that the bi copter is jittering while you back.
Classic over-excited tricopter wagging it's tail :D
So awesome seeing you again! Come back as often as you can!
I was wondering if you could put a fpv camera on a Servo on the front of the bicopter and when the motors move the camera moves
david went from looking like a swedish computer engineer to swedish viking
obscurVEVO Thomas the tank engine to God of War
obscurVEVO he remind one of the WWE wrestler name Erick Rowan with a long beard who is the one half of the tag team , The Bludgeon Brothers.
Pewdiepie's brother
Suburb the ongoing Islamic terror invasion in Sweden, reviving viking values like family, community, honor and especially resistance is crucial.

So im 55 seconds in, wondering when Dave was going to show up, and then the guy with a beard spoke... whoa!
Spartacus FPV right? Lol
It took me a minute after I matched the voice to lips moving. Lol
They literally introduce him right at the beginning... its not like he grew that beard last week... He has had a full beard for at least a year now. lol
Where is his baby face?
I'm a simple man, I see David (in any form) - I thumbs up the video.
AMEN
Chris Corbett I
Chris Corbett yup
Here he appears in Kratos form
That's not even his final form.
Man, I miss David and FliteTest good ole days...
Kevin,,,,,I totally agree with you. And I agree with Drew in that the quad movement has gotten to serious and has lost the good hearted fun factor. For those that don't remember the beginning days of Flite Test, especially when David would join in,,,,,take a glance back at some of the old videos. It was all great fun and innovative at the same time. And much of the information is still applicable today. Again,,,,,great video and Chad,,,,,glad you jumped in to add a bit of old time mix. It was also heartwarming to see a video shot at the origin of Flite Fest,,,,,Chad's back yard,,,,play set and all!!!!
and when peter with his crazy plane idea still there.
Rocket plane!!!!
Wtf is dood ole days you men goda gamla tiderna
When flying backwards, the "tail feathers" are providing a positive feedback (which amplifies any deviation from the desired angle) thus forcing the controller to apply significant corrective input. Because the amplitude and phase of that effect is different to the static/forward flight dynamics, the PIDs in the controller become all wrong and you get that oscillation.
Can you repeat that in english please. :P
The tail feathers act like a sail in reverse, instead of the fins of a rocket (when correctly oriented)... they proportionally grab more air as they become more misaligned with the direction of (backwards) travel, which causes a progressively stronger reaction from the PID loop that is trying to center the "stick" (PID setpoint). Thought experiment; why isn't the rudder on the front rather than the rear of a boat? What would that feel like to steer if you had an non-steerable motor on the rear of the boat providing fixed thrust. Stick your hand out the window on the highway jutting forward versus backwards... feel the difference and you should instantly develop the necessary intuition if you haven't already.
Thank you for imparting your knowledge Bruce :) Hmm wonder how we can fix.
David Windestal make it symmetrical....
DELLBOY2013, might work. How touchy would the CG be?
So great to see Chad and David again.
Leave it to David Windestal to make RC interesting. Everytime.
Love that people, like David, are still exploring and pushing the technology for new (and old). good to see Chad and David together again.
It's so good to see David back! The rotor maniac is back! New FPV people have to learn who this maniac is and how much he did for this hobby
Why did he leave flitetest
Great to see David involved with rotor riot. Don't let him get away again chad
12:45 most awkward hug and neck lick ever
I need the bicopter!
Giaco Whatever he would trade for a maker knife maybe :)
Didn’t know you were a drone guy!
That BiCopter looks like something out of RoboCop!! Awesome!
Megatron in transformers animated
love that you have David on. He might be the most creative person in the hobby. More David!
Best Rotor Riot Episode yet! Please make more Videos with Drew & David!
I'm Bi...copter curious ;) Love these cool and unusual machines!
lol Zoe! Yea the unique stuff like this always gets me excited. David is a legend, great episode.
NJ Tech David's enthusiasm and love for it really helped inspire me when I was getting into it. Without him, Kapper, Alex, and the Josh's I may not have ever found my love for aviation and FPV.
without a doubt, it's the side of the hobby that drives innovation for me, gets me going every time. This bind and fly world dont know they've lived! haha, are we sounding old yet? Hope you can come back for another LDO show soon, sad i wasn't around to chat with you last time. When you're on next ill dig out all the old frankenstein flying things i botched together before stuff flew good out the box lol.
As soon as I saw the bi-copter I had a wierd feeling it was meant for 3D flying. I think it's the agressive backwards attitude!
haha, nice.
Great to see you guys again David and Chad! /Old school FT fan
Awesome. Love David. So creative and experimental. Chad nailed it.....Innovate for fun. Really enjoyed this episode. I got into fpv in 2013. A lot has changed over the years. It was all experimental and trial and error back in the day. Incredible how far this hobby has come thanks to dudes like David. I still watch his balloon drop FPV glider from the edge of space video every couple months. High fives. Thanks guys.
So great to see David and his creations again. This really reminded me of the old Flitetest episodes where he built all this crazy stuff. Loved those! This kind of stuff is the part of RC I always enjoyed the most!
Drew's commentary while flying reminds me so much of my first time flying quads.
I love it! Drew: "Why? Why? Why? Why? Why?" and of coarse David's response: "I don't know yet." At least the garage didn't catch on fire like the time he built the jet plane.... : )
7:15 Bi-Copter looks incredible! Dude is right, people need to carry on innovating on things other than quads!
Love seeing David back over there! Miss him so much on FliteTest, he's such a great innovative guy. I was always a fan of how the tricopter flew, I hope more pilots will be getting into it again!
I LOVE DAVID!!!
the last words of David made my day ^^
I am from Bali Island. You are one of the pilot drone racing masters. I want to learn to be like you. Even though I don't have a racing drone.🙏🙌
David!!!!! Can't believe I'm seeing that legend again!!!! It's a good day on the tube
7:19
"A bicopter"
"I'm curious about this"
"He went there"
😂
The laugh was more crinchy than the bi-curious joke haha. Seem we evolve with time after all.
fuckin autistic attack he had
killer episode...
I am so glad to see David and his innovations. Keep pushing the creativity.
I love my baby tri. It's such a different world than my mini quad and David has been such a help for any issues I have had. Top notch service.
Chad was right...and it has been the hobbyists who have been the Innovators in this hobby and it is THAT , the FAA- commercial Drone Industry and sadly even the AMA that is trying to stick a fork in and end it.............one creates an idea and those who join it help perfect it...take that away and this Hobby dies and tech dies as it was spoken....they go to this point and then they stop.....and The Swede-Windestal, has been doing some great innovating for awhile as has Flight test ( what Chad started ) and even Rotor Riot and many many others......THAT is what has made this HOBBY what it is.....and has gotten many more in it and is spreading ...we can not allow that to end......WRITE Your Congress person and make sure they keep all Hobbyists rights to do just that ..................GREAT Video......what Dreams are made of.
Well, even Silicon Valley Start Up's selling ideas they jus copied from the hobby and call it robotics. As an examples the GPS driven mapping wings. Or the disposable drones for DARMA.
No. This hobby was around a long time before those guys were even born. One might even say utube vids like rotor riot is famous for, ruined the hobby by attracting negative attention and encouraging idiots to what was never considered to be a dangerous hobby by any authority.
I built model aircraft as a kid ( I been around a long time ) saved money hunting and returning bottles, in those days money was hard to come by, much less be able to afford the materials to build a flying aircraft, it was years in the making and .. long before the internet , No clubs . no body i knew who ever did such a thing ...needless to say I had little success in flying, and I still built after watching balsa wood shatter, was frustrating. needless to say life got in the way and i moved on, but that DREAM remained....fast forward a vast many years, now an old man , with New tech, a wealth of info By Great Friendly Hobbyists, I jumped back in after a few years of researching, just reading the articles of those whining about Lipo batteries almost kept me away.....did more research and learned Lipo's are dangerous to those who refuse to learn CHANGE....Needless to say i am flying and have been awhile and now getting into FPV and flying quads and the only ones ruining the Hobby are the morons who think hiding behind locked gates flying and demanding everyone kiss the AMA and pay them dues to have a cook out or fund a group of people in Muncie who are trying to steal the hobby away from REAL Hobbyists ...and ZERO to do with Utube vids or RR, or anyone else ( other than a handful of people who fly near manned aircraft, which only seems to occur when the AMA and FAA and DoD and ALPA starts screaming to end the Hobbyists freedoms and end 336 ) and to do with whiners who would rather sell their souls to Commercial drone Industr, the FAA and the AMA who is also backing them to force membership and AMA sanction field flying only. R U one of those people J-BOY?
Imagine being a gun owner. Government over reach is nothing new
why we own guns...our Government is our worst enemy
You better start develope a single rotor copter!
Oh wait...
why not? with 2 servo's and a complex mechanical knee joint :D
psydafke i wonder how that would work. so innovative 😜😂
Would that not just be a helicopter then with 3 Servos and a swash plate 🤔
4 servos including the tail rotor
Someone has done this. Its in a ted talk
Love this. Love just about everything David comes up with. I was crazy bummed missing Flittest this year after seeing he was there.
my first RW was David's mini-tricopter I built in 2016, so much fun and I learned heaps about how things work. SO MANY servo calibrations...
They've not developed tricopers for a long time because everyone follows the money (i.e. miniquad market), now that the miniquad market is saturated the time is right to do other types of models.
Analog feedback servos are still a bit uncommon, not that there aren't solutions;

Chad's intervention is the best part of the video
The oscillations occur when the control surfaces are facing forward in reverse flight. it's like putting the rudder in front of a ship, and the drag induced causes the sensors to try to compensate by adjusting the thrust vectors. Another analogy is like trying to plow a straight line by driving the tractor backwards. The resistance is sufficient to induce larger deviations from the normal and the adjustments must be even larger to compensate.
Absolutely Awesome! So good to see that old Flitetest location again. Hope you guys do more videos like this!
let's call them flippy-floppy-spinny boys from now on.
Na that's already what I call my nutsack
Davids head looks so thin and long now :D
Great to see DV again. I was just looking at some of my old TC V2 footage and thought it was quite good for an aircraft without a gimbal. Great design David!
Great episode.
Even better to see David on it!
"he's a hoot" 😂
Wtf happened to david?!
He came out of the past 10 000 years right?
He turned in to Leif Erikson! Fringa hinga durgan
manuel A. Nothing he's been making videos on the regular. Where Have You Been LOL
I wouldn't call his upload rate regular but he has been uploading
ROOOOOOOOOCKET KNIIIIIIIIIIIIIIIFE *Guitar Riff*
manuel A. Isn't it obvious? He invented a time machine and just recently traveled back to the future and his rocking his 1200AD Viking look. I'm also pretty sure he stole that Bi-copter from the year 2026. Don't ask me how I know, but I'm sure he's a time traveler #FromTheFuture
Who is this red bearded wizard???
David Windestål?!?!?!?!
Feels like the good old days of Flite Test! Good chemistry with you guys, so much fun to watch!
fun to watch episode, thanks!
the explanation of drones:
quad - four spinny bois
tri - three spinny bois and a flippy floppy
bi - two spinny bois and two flippy floppy's
1000th comment great vid guys!!!
Lol..."He's a Hoot"
Jason Olson I laughed uncontrollably for some reason at that :)
Nice to see David around! Great video guys!
I love how innovated Dave is. Funny seeing him with a beard.
I saw the bi copter at flite fest and I saw drew hover it
Yesss the sweed is back were he belongs!!!! IN THE AIR!!! and the USA. 😂😂😎😎
One of my favorite vids... just a dude and ancient Viking from the future pushing the boundaries of flying doodads. Please keep us updated!
Great to see David again - love to see the tinkering and that bi-blade looks super cool. We really should have David working for NASA or something.
David has become nerdy Kratos.
Feathered Kraterd? Nerdtos?
Krardy.
What if the bi copter frame with a stationary third motor = Tricopter with better yaw/roll authority?
2+1=3
Luuk Cornelissen that’s not what he meant
So two servos and 3 motors
It is great to see David making videos again!
Always loved this tricopter design! Keep up the fantastic work David!
Dam that was close!!! I have a friend that climbs those towers and puts those attachments on!!! They are very expensive!!!! I'm glad you did not hit it!!!!!!!!!!
DRONE review man of all drones !
DRONE review man of all drones sorry, am i annoying you? 😂
Its a pretty simple omni antenna on a 3ft standoff, it prob would have done more damage to the quad than to the antenna. These Omni's are actually the cheapest antennas that you would find on a tower because they have no electronics on them.
I moved in my chair. How did you all not move? 2:28

What an excellent upload! Reminds me of the old FliteTest days. Super fun. Thanks guys!
Congrats David to your crazy innovations👍 and a super fun episode too😁
Is this guy wearing an eye makeup???
Wtf is wrong with this world?
ask to the mirror... He is Le Drib.
Its Le Drib
The 3 Amigos, great video guys! Great to see three of my favorites in one place.
Hahaha the ending man got me in stitches 😂😂😂😂👍🏽
Great job guys
That was fun to see somebody usually flying insanely smooth, now struggeling like he flies his 10th Lipo pack.
AND: Good to see David back. He is so much more entertaining than anybody else
David, you sure made two amazing designs that are off the wall! Keep up with the innovation, and I hope to see more footage of these unique masterpieces! Drone on!™
David the LEGEND! Nice to see you here...
Awesome episode, and so fun to see David again, and he looks amazing in the beard :)
Yeah! DAVID is one of the OGs! What a legend
Great to see you back David
It's good to see Chad and David! and that bicopter looks very interesting ...
So awesome seeing Chad and David together at the original FT field, miss the old days, awesome to see both flying and tal koo ing together!
Really appreciate this one. As a new quad pilot (71 yo noob) I’ve been looking for a tricopter and here one is. I think my brain will gravitate toward easy cruising rather than acro but still enthused about it all.
It’s great to see David back at Rotor Riot.
Always nice to see David :)
Loved everything about this video. That bicopter is SO cool! Thanks for bringing it to FliteFestOH18!!
So cool to see David continuing to innovate and continue the tricopter design. After you/he left the Flite Test team, I totally forgot about tricopters. Going to have look him up on his RC Explorer. Thanks for posting. Been a long time since I have seen Chad in a video.
I love how calm beard guy is and the pilot is having mini heart attacks
11:25 100%
And yet here we are 5 years later and we still dont have much tri-bi copter innovation (in terms of, them becoming well tuned to compare with quads).
To think we've reached the apex of drone flight in 2024 is incredible hubris.
Hello after watching David's early tricopter video I scratch built one and love flying it good luck with the new projects
LOOKING AWESOME DAVID!
Man, You handled those birds like a Boss! Great Video, Thanks
The handshake was sincere and professional.
I just fell in love with that bi-copter... it looks so cool and I am sure that it would give much more flying time than a quadcopter.
Enjoyed seeing David again!
Great seeing David again. Man o Man, Viking Beard Check!
David is awesome. Seems like a cool guy to hang with. He look so different these days. Awesome video guys!
DAVID! I loved him in the OG FT days. Still reckon he is the best 😁
Great to see you again David Windestål, and I like your beard!!
cool video guys always nice to see david with some new tech.
It's so refreshing to see David and Chad. It's been AGES.
Cutting the edge. Cool stuff!!
David is awesome! Great job guys!
Wow blast from the past, I just realized that one scene from 2011 with the yellow parachute thingy on the islands... That was one of my main inspirations like "I wanna do that too!" and one of the things I showed around back then to show people what I'm even talking about.
Those were the days man, getting nostalgic here^^
Love to watch David, he’s dreamy
Good to see David again, him doing the Vampire with afterburner on flitetest is still one of my favorite episodes on youtube.
I'm working on three tricopters and two quads, right now! Love it👍
