Helis can be more aggresive than multirotors since on a heli, you don't need to stop the motor and take the props to the same rpm reverse which takes quite alot of time compared to a heli changing pitch of it's blades.
i think alan found the quads weak spot....and man did it take ALOT of crazy shit to find it! I am absolutely amazed this is possible from a fixed pitch quad. Good work!
Man... this guy has had a lot of flight time on the sim to be able to fly like that. "Props" to him! I wish I could fly in acro mode like that, I'm only good at attitudinal mode.
Alan Jr is a professional rc helicopter test pilot, and among the best in the world hands down. Search his name along with "Align 500 heli" (or 600 or 700 etc.) to see what he's really capable of! Should hopefully blow your mind ;-)
Alan Hunt Nah man, Alan is a world class 3d heli guy. His dad's one too. Alan flew for ALIGN as long as i could remember. He is testing the quads ability, not the other way around.
Reversing motors has no additional wear if you're using motors that are overpowered for the copter size. the bearings don't care if it's a pusher or puller config. You only have to worry about the small gauge wires over heating do to constant amp changes. A large motor with thicker gauge wire will solve that.
yes it reverses the motors. As long as the motors are good and powerful enough its not a problem. They will get warmer than on a normal quad but nothing to be worried about. I'm building a 3D quad myself right now.
R/C Cars do this already. Go off a jump and want to level out you will reverse super quick. Or if you're going down a long straight away and want to do a skid you reverse the motors. Nothing new.
Juan Francisco Lopez-Sanchez they're most definitely brushless. Brushed motors kill themselves running in reverse, wouldn't last a minute in the air like that. all multirotor ESCs I've seen released in the past couple years can be programmed to run bi-directionally. The control signal from the flight controller has a resolution of 2000 steps usually, and most ESCs have much lower actual output resolution, so splitting the throttle channel in half, top for downward thrust and bottom for reverse thrust works excellently. The only thing stopping most quadcopters from performing like this is their software configuration, and props that are optimized for downward thrust. I've seen a nitro engine mounted on one of Curtis Youngblood's stingrays, that's all I can really see as an advantage to a collective multirotor. In the middle, the thrust stops, but the blades don't necessarily. A well configured flight controller always maintains stability and desired heading. gravity is gravity so if you're perfectly sideways with zero pitch versus zero motor rpm, you're still going to fall until you flip over.
alanszabojr I have to imagine that seems pretty boring to you compared to your normal fair. Have you tried the stingray? I'm wondering how it compares to the reversing ESC models. I would think CP is faster to change direction.
Just got mine and am fairly new to the hobby. The instructions for me are way to vague. I have a Taranis QX7. I have it bound to the RX but thats about it. Other than a blinking green light on the flight board nothing else happens. Can u explain how to get this flying.
alanszabojr hello I saw your videos and it's amazing what do you with drones. Congratulations I was wondering if you can give me some advice as I do that?
There's no way that after the second crash the props would have been in one piece....and at least two arms would have been bent to hell. Have had two small mishaps with mine and it definitely isn't that forgiving in a crash, luckily it isn't too expensive too fix.
Amazing flying! Sounds like a lot of suffering for the motors though. I'm thinking about doing this with my mini Hex I'm building.... but I'm concerned my motors (cheap multistar Elite 2204) might get damaged due to those rapid RPM changes... what do you think?
AndyKayJah rpm change cant hurt a motor. there is no brush, only a collapsing magnetic field. the stuttering you think you hear are the motors reversing so it can fly upside down... ie electronic negative pitch.
Diesel Ramcharger it doesn't physically harm them, but reversing so fast draws lots of amps, and it does take a toll on a motor if its not able to handle it the amps.
Diesel Ramcharger Yeah I know it's reversing the motors... how else would he be able to fly such maneuvers^^ I was just wondering if this might harm the motors' bearings or something.
im guessing motors are flipping rotation like on helicopter the blades change pitch to fly upside down these motors instantly change direction im waiting for collective pitch rotors on a quad with swash plate, serovs and all that then it will be super maneuverable as long as the blades to flex too much
The advantage of this over a CP design is the simplicity, efficiency (longer flight time), and robustness. A CP design has a lot more moving and breakable parts. However, CP is faster at reversing the thrust and has a bit more "float" due to the blade's constant speed.
Very cool but I'll have to wait and see how long the motors work with the abuse they are taking by starting and stopping all the time. If the motors hold up, I'm in.
If there gonna make these for 3d I wish they would change the design or add a canopy something it just looks like a crazy X flying around. I get the skill level it takes to do this but it's just very pleasing to the eyes my eyes
peter pottinger I fly FPV inverted doing crazy 3D all the time. There is no getting sick, it just feels very natural and easy. But then I grew up flying fighter jet simulators in the 90s and that is a lot like FPV aerobatics. my videos are on Vimeo though.
Good ESCs use regenerative braking, similar to a hybrid or electric car. Either to recharge a capacitor on the board, or the battery itself. It's not much, but definitely offsets the upcoming punch in the reverse direction
Saludos viendo su video creo que es el piloto mejor preparado manualmente y con los reflejos mas rápidos, pues yo soy nuevo en este tema tendré como 40 horas de vuelo y no me cabe en la cabeza como puede reaccionar tan rápido en los movimientos y puede estar pensando en la posición del dron. Es un maestro debería dar clases o realizar algún video de como prepararse para estas cosas. Las casas de drenes no deberían dejar pasar la oportunidad para darle sus nuevos aparatos para que los pruebe y dar su opinión a los constructores. Gracias por su video me deja muy impresionado.
IF I didn't see the remote DX9 and the hands pilot at 4:05 I will say its just a FLIGHT SIMULATOR!!!!! great job... How I wish I can fly like that... emmmm, let me change that,... how I wish I HAVE that quadcopter!!!!
If I can put on my goggles and fly fpv and not hit any trees,branches,mailboxes,cars,poles,bird feeders and land 6-8 minutes later.... Its a good flight. Alan's always blown my mind regardless of what he is flying. I just do not know how he can keep track of which is the front during all those moves.
As impressive as this is, no quad will ever look as good as a single rotor heli doing 3d - Period.
#KeepRCHelisAlive
Yea, I agree. Multirotor doing 3D doesn't have the same appeal as a helicopter doing 3D.
Also, I'm with ya on #KeepRCHelisAlive
Helis can be more aggresive than multirotors since on a heli, you don't need to stop the motor and take the props to the same rpm reverse which takes quite alot of time compared to a heli changing pitch of it's blades.
Coolest squeaky-toy ever!
I bet the ESCs for the motors are very, _very_ unhappy by the time the test is over...
I guess rc cars have been doing this for a long time but it still blows my mind that the motors are doing that.
Amazing flight Alan. Thumbs up again for this one!
almost three years later and I have not seen any better.
from 3D helis to 3D quads... simply awesome!
Its nice to know that even alan crashes sometimes
+Daniel Perkins hahahahayea:) I also feel a little better now :D
+Daniel Perkins He only crashes when he fly a piece of shit quad like this lol.
Every 3000 years.
Your flights never cease to amaze me dude, awesome video and keep it up!
Love your videos, feel like I'm watching a recording of a flight simulator.
That series of cross-axis flips was pretty cool
Thats amazing. So nimble and stable while doing it haha
i think alan found the quads weak spot....and man did it take ALOT of crazy shit to find it! I am absolutely amazed this is possible from a fixed pitch quad. Good work!
What was the weak spot? You should look up warthox videos, i think hes on vimeo. He was doing some crazy quad 3D a couple years back.
Diesel Ramcharger fixed pitch?? how is this possible?
polloviz it runs reversible speed controllers. reverse direction of rotation reverses direction of thrust
nice! what about flight controller? which one supports those ESCs?
Alan You are just Plain Good @ Everything Very Nice Video & Flying also ! Nice Quad !
Wow, this was 7 yrs ago?! That’s pretty cool, 3s I assume??
BAD ASS you never stop get you some more
Awesome ! ! The totally flips me out ( pun intended ) lol Amazing piloting skills Alan ! Thank you for sharing this :D
Great flying....nice quad
Fantastic!! Was this 3S or 4S? Mine just came today! Can't wat to fly it.
Looks fun! Nice flying👍
Nice flying. . That things sounds crazy.
that is sick
***** I love the current chopper sounds !
Some like a mad beehive with emotions
hello I saw your videos and it's amazing what do you with drones. Congratulations I was wondering if you can give me some advice as I do that?
Show your sticks alan? Is this a sticking experience like invertex and simonk and ultra esc or can you add throttle curves as in a cp heli? Thnaks
INCREDIBLE!!!!!!!!!!!
Do the difference colored blades and LEDs on the bottom assist in determining position during flight from a control standpoint?
Man... this guy has had a lot of flight time on the sim to be able to fly like that. "Props" to him! I wish I could fly in acro mode like that, I'm only good at attitudinal mode.

I meant to say as well that it's collective pitch stick, time not Sim time, that got him where he is.
Alan Hunt Nah man, Alan is a world class 3d heli guy. His dad's one too. Alan flew for ALIGN as long as i could remember. He is testing the quads ability, not the other way around.
Reversing motors has no additional wear if you're using motors that are overpowered for the copter size. the bearings don't care if it's a pusher or puller config. You only have to worry about the small gauge wires over heating do to constant amp changes. A large motor with thicker gauge wire will solve that.
Awesome!! I say again you are Master!!
Nem semmi ahogy repülsz vele. Gratula :)
I presume you're at 0 throttle at midway and reverse throttle below that? That's some impressive thumb twiddling.
Well this might be the best pilot on the planet...
awsome flying !!
How can it do 3d trick while the rotors cant change the pitch?
The motors reverse their direction
does the proppeler change spinning direction rapidly?
i think that crash because of technical problem haha
nice one
Am I at an EDM concert😂👂❤
AMAAAAZING
pretty sick dude
Is this collective pitch or are the propellers actually reversed?
Is it just reversing the rotation ? If so, how long are the motors expected to last? Must seem like a proper thrashing....
yes it reverses the motors. As long as the motors are good and powerful enough its not a problem. They will get warmer than on a normal quad but nothing to be worried about. I'm building a 3D quad myself right now.

very cool!
These have to be sensored motors to reverse that quickly! No? Impressive!
Ok question. Is this using reversal of the motors or some kind of CCPM?
motor reversal and bidirectional propellers
alanszabojr I have to imagine that seems pretty boring to you compared to your normal fair. Have you tried the stingray? I'm wondering how it compares to the reversing ESC models. I would think CP is faster to change direction.

ez fasza jo!
Awesome!
he must be crying give me back my helies LOL
That was awesome!!!!
alanszabojr hello I saw your videos and it's amazing what do you with drones. Congratulations I was wondering if you can give me some advice as I do that?
+Mikchel Maia firstly, caling them drones is not the best idea. Secondly, get a heli fi you want to fly for fun.
Quadcopter in steroids lol. Cool.
Jesus, didn't think you could fly a quad like that.
she got a name..................... she is a "KungFu Copter"...!!!!!
What did you smoke before you fly?
how do you configure the throttle settings on base flight?
Nice! How can you tell what's front and back, top and bottom?
Kidlat432 Its hard to tell, but it looks like their are different colored props on the front/back as well has LEDs on the bottom.
can you mow my lawn lol
Where and how much?gotta have one.
There's no way that after the second crash the props would have been in one piece....and at least two arms would have been bent to hell. Have had two small mishaps with mine and it definitely isn't that forgiving in a crash, luckily it isn't too expensive too fix.

KpilotRCHelis so I assume it would be best to use a little overpowered motors, so there's a little reserve regarding the amps
wonderful!
im guessing motors are flipping rotation
like on helicopter the blades change pitch to fly upside down these motors instantly change direction
im waiting for collective pitch rotors on a quad with swash plate, serovs and all that
then it will be super maneuverable as long as the blades to flex too much
They already have a CP quad on Amainhobbies
But i think the motors spin at the same rotation but just push air in both directions?
google stingray quad
The advantage of this over a CP design is the simplicity, efficiency (longer flight time), and robustness. A CP design has a lot more moving and breakable parts. However, CP is faster at reversing the thrust and has a bit more "float" due to the blade's constant speed.
Topxe
Agreed. I still think the stingray is the better design overall. That guy Curtis knows his shit...lol
Very cool but I'll have to wait and see how long the motors work with the abuse they are taking by starting and stopping all the time. If the motors hold up, I'm in.
as long as they are powerful enough they will be fine. Obviously if they can handle Alan they can handle anything :)
Incredible
awesome
202 komment és az enyém a 3. Magyar nyelven,igaz ez is Németországból.....
Amúgy atom vagy :)
nice
is that ESC noise or motors rapidly switching directions?
either way this baby rocks
any idea on price?
Probably the motors
Price will be $469.99
The squeaky noise is the ESCs.
This is next level quad copter flying. And I don't think you can do this on a dji drone😂😂
Not on dji, you can on 5 inch tho
If there gonna make these for 3d I wish they would change the design or add a canopy something it just looks like a crazy X flying around. I get the skill level it takes to do this but it's just very pleasing to the eyes my eyes
Meant to say not pleasing
there is a canopy on their website
just fly it FPV. best view of all
sross148 lol 3d fpv you would get sick going upside down and back, plus flying upside down in fpv would need a new skill level!
peter pottinger I fly FPV inverted doing crazy 3D all the time. There is no getting sick, it just feels very natural and easy. But then I grew up flying fighter jet simulators in the 90s and that is a lot like FPV aerobatics. my videos are on Vimeo though.
Awwwwwwwwwwwwsome
Amazing
what flight controller is that?
you have more fun than copter ? :) I think YES :D
What are the differences between this and the Invertix 400?
size mainly , and price
shiT!!!!!!!!!!!!!!!!!!!!!!WHAT KIND OF THAT DRONE?
Wouldn’t dis be a good choice for beginners getting into Helis?
No, you have more axis to learn, learn on a normal 5 inch and stick to it, helis are bad
What does it do with the kinetic energy in the props when reversing?
Good ESCs use regenerative braking, similar to a hybrid or electric car. Either to recharge a capacitor on the board, or the battery itself. It's not much, but definitely offsets the upcoming punch in the reverse direction
sounds like them motors do not like going in negative to postative so quick lol
Brutal..!!

I feel sorry for the battery.
is it unable to change the propeller pitch?
yes, the motors change direction
It's faster then I think darn.
Hey guys this looks amazing! BTW if you put in front of your web address in the description it will become an active link
IF I didn't see the remote DX9 and the hands pilot at 4:05 I will say its just a FLIGHT SIMULATOR!!!!! great job... How I wish I can fly like that... emmmm, let me change that,... how I wish I HAVE that quadcopter!!!!
ohhh and the PILOT is running on 4:32!!!!.. sorry I post it not finishing the video... :D
Woooow! It's very weirg to see, but fun! hahahaha
Reverse pitch? or reverse motors??
Motors
Oh my GOD!!! hahahahaha, I WANT ONE!!! xD
omg，so nice！
wow
amazingg
Space age Frisbee
man there is something on the way...!
Wow.......
If I can put on my goggles and fly fpv and not hit any trees,branches,mailboxes,cars,poles,bird feeders and land 6-8 minutes later.... Its a good flight. Alan's always blown my mind regardless of what he is flying.
I just do not know how he can keep track of which is the front during all those moves.
experience and different colored propellers for front (white) and back (bkack)
I also have different props and also led strips on the bottom that are the brightest I have ever seen. My eyes are close to 2x his age though.....
真牛啊！！！
If the blades don't pitch in and out, how does it fly inverted?
Blade the motors can reverse very fast. Thats the reason of that weird sound.
JensHCW This would be a nice sim airfield.
JensHCW Ah yeah! I think I want one of these. I just dont want anything yanking away from my 3d Heli practice.
Blade well if so, good luck!
JensHCW Thanks man! I like these flying X machines.
Not as powerful and fast like a heli, but still cool.
