This is *hands down* the best *serious* discussion I’ve seen about miniquad setups and methodologies between freestyle and racing period. I’m bookmarking this so I can rewatch this again with my friends.
I’m gunna listen to the kid. The unbiased difference between each pilots information are the results which have been accomplished directly compared to any a-posing theory. In other words; racing is the foundation of any freestyle in any medium. He is not speaking opinion, what he likes, or what he enjoys flying. He is talking about successful results in the top skill level. I respect all of these top level pilots and their willingness to share the theories which make the benchmark for their preferred discipline of flying. But when theories contradict; I know the racer or racing discipline leaves little room for opinion. If you take your opinion to a race, you will leave with one of two; a changed opinion or a proven race advantage. Either way, opinions morph into fact or failure somewhere between the start and finish line. The kid is the only one that Understands this perspective (josh excluded; of coarse). But you are all inspiring, supernaturally skilled pilots setting the benchmark for the sport. Thankyou for sharing!
I got into this hobby 6 months ago or so. All I wanted to do was fly and remember thinking, who cares about all that deep mumbo jumbo stuff. NOW, just a short time later, I can't get enough of the nuts and bolts aspect of the hobby! Because of guy's like y'all, Steele, and Rotor Riot, I have been able to take this hobby to the next level. Thanks to y'all, my Fpv experience is beyond awesome! Thanks for doing what you do!!
25:50 Basically, it's like a Ice Skating dancer, when he stretches his arms he spins slowly, and the closer he pulls his arms to his body (the center of mass) he starts to spin faster, the same principlee. I think lol
Vanover`s reaction to the freestylers`s quad weigh was like an F-1 driver reacting to the weight of a nascar lmao. Really cool to see the priorities the pro`s have, and what the preferences are for not only the types, but the different people. Me:watches youtube reviews and goes, "hmmm, Hawk 5 or Buzz?" (had a Hawk in checkout, then bills happened :/ but hey, the weather has been crap anyway so..)
When talking about the different frame styles, takes me back to my days of archery, where a long rod (stabiliser) with weights on the end would effectively slow down your movement of the bow when aiming, more weight as long as your strength and endurance can handle it mean't essentially aiming became less twitchy and easier to hold on target. Same physics principle regarding arm length and stretched X frames etc.
You rotor riot guys are fantastic for the hobby. JB has been there for us all for a while now. Love you Betaflight Devs out there. Betaflight has become so amazing. Given so much to the community
Where would we be without Rotor Riot? How would we get this information, who would be get educated on all this ,who would bring freestylers and racers together. Thankyou Rotor Riot for all youve done for the community.
Very interesting, I have my first event next week but have been practicing hitting Gates. I had to get rid of my stretched X bottom mount because I just could not fly it well. So my first event will be covered with 2 top mounted chameleons which I have far more control over
At 28:20 he nailed it. The one that feels the best! Flown all and a stretch X at 500g AUW seems to work for me... it's a bottom mount, although I do prefer top mount rigs and still fly a qav 220 squishedX on my 3rd bottom plate, no arms needed yet! Great chat... Cheers
love how the captain is Sooo annoyed by anything that's not about speed, efficiency, lightweight and lap times.lol And it's totally blatantly obvious on his face,,,He just can't be bothered. 👍😂✌
He a young millennial and can’t be bothered with thoughts that are not of his own. He’s also unfortunately a very good racing pilot which just makes him arrogant in his young age. Three adults and a child talking about multi-rotors
I personally dont believe having the absolute lightest setup is the be all. Take a look at Thomas Bitmatta, he has taken out international championships with a quad most racers wouldnt even consider simply because its 100g heavier than what a lot of the racers out there are using
Prop pitch.. In a theoretical no slip environment. a 5x4.3x3 prop would move forward 4.3 inches for every revolution. A 5051 would move forward 5.1 inches for every revolution. In reality we don't live in a "no slip environment", so other things in prop design come into play to minimize the slip that will always be there to some extent. But that is the "nutshell" explanation of "prop pitch"..
The best discussion about quads I've seen to date!!! Great video Guys!!!! Was odd knowing Drib was there and didn't get to hear his opinion on all of this... Liked the format too...
I really liked this discussion but when you guys were talking about the different frame styles and sizes you all forgot to mention how it keeps the “dirty air” from the front props from affecting the rear props. I still learned a lot from this video. Thanks guys!🤙🏽👍🏽😃
Well the trouble is with stretch frames the 2 front motors and 2 rear motors are so close together that they affect each other in a bad way.. so you are correct in theory, that the front props dont affect the back props, but they do have a big sideways effect.. i just transfered a quad from true x to stretch x.. and it flies awful, i have to force it round every corner, it is faster, but not enjoyable to fly.
Not practically giving an answer to any of the issues being discussed, so no, that is not the short answer, as it`s not actually an answer. That`s a summary definition of the math involved, not an answer to "race VS freestyle".
Great discussion guys. Thanks. There is still a lot of personal preference involved and much of it is subjective. I learned a lot from everyone's different approaches and ideas. I now have some new things to try.
A frame designer demonstrated that if you tilt a short kwad on a 20 degree angle. The rear prop catches air turbulance from the front. A longer x on the same angle. Lifts the following props through cleaner air. No difference on straight punch out. But, much more efficient for forward movement. I believe this theory.
Yeah I agree with Anub - small props on a bigger ride is a smoother feel. When people ask 5" or 6" I always say 6" because you can fly either prop and you lose nothing when you are flying it 5". So for flexibility a 6" with 2150KV lets you fly great with 4s or 5s and 5" or 6S so if you have 4s and 5s batterys you can go from fairly docile long(er) range 6" to zippy 5" and anything in between. I really like Anub's approach to this - if I'm not subscribed to his channel I'm about to subscribe - hope he does lot's of talking head stuff.
Agree that streched X are faster than true or compressed x and l believe that is because they have less drag (think of a swimmer jumping in the pool like an arrow and a parachuter jumping with arms wide opened).
Best overall frame for race and freestyle: Hyperlite Floss 2 with 6" arms running 5" props. You can toilet tank the battery and have a gopro without worrying about chopping your power leads. Its a lightweight frame with 5mm boomerang arms so definitely durable and easy to swap out if you do break something. Also Im a little sad that they didnt touch on propwash when discussing frame footprint sizes.
Seriously though floss 2.1 with 5mm boomerang arms is the best frame out there. Strong, lightweight, fast. Does everything. Race, freestyle, long range. Top mount, bottom mount. 45 bucks. Also running 6 inch with 5 inch props. Love it.
Another data point - my best flying stuff are my Floss2.1 6" running 5" props. Despite cheap beater motors/esc/FC/VTX/camera on these builds, I can do everything with that setup.
Now one of my favorite videos! I learned a lot, esp about props, more table talks like this please! Also, can someone comment what the filters that all the gopros have stuck to them are? Are they just lens protectors? What brand?? Thanks!
Sometimes just protector but usually ND filters.. gives improved footage depending on the daylight intensity. It's a photography thing, so plenty of info out there. Try RUclips search for something like "fpv nd filter". Cheers.
Love the discussion! This hobby needs people talking about "things".but At some point if your are in the hobby you get it. I mean, of course parameters like weight, kv or else, change the beaviour of your qwad! Did everybody use expo!? RC rate? PID? I got it is pro pilot taking. Anyway I am also drunk and I enjoy a lot rotor riot's video.... Drone freestyle or racing, is like mario kart double Dash. Donkey or toad! Style or speed
I think the biggest thing that Stingy and Zach hit on is actually the best takeaway for a newer pilot - if you like the feel of one family of propeller, then sticking with those is going to work really well if you vary what you are looking to do. Optimizing the efficiency range for your setup to how much throttle you're actually using AND how much time you're spending at what AoA (i.e. unloaded, or backing into turns on tight race courses) is really key... and being able to do that without relearning the feel of the props - how they transition from loaded to unloaded, or react in propwash - so sticking with one prop family makes tons of sense. HQ V1S: 5x4x3, 5x4.3x3, 5x4.5x3, 5x4.8x3, 5x5x3 - full range of excellent, light, snappy props DAL Cyclone: T5040C, T5045C, T5046C, T5050C - my preference are the V2 5046 cyclones
Hi guys. Sorry but any chance to create a kind of a chart motor/ prop/ battery/ kwad weight. I know it is quiet a lot to ask for but you are among the most knowledge able i know. Thanks.
The problem with frames that get too small is not just the leverage issue but also the props start interacting and upsetting each other and this is completely not what you want to happen. Each corner needs to be able to do its own thing without changing or interacting with one of the other corners or otherwise the stabilization calculations become massively less effective.
YES around 13 minutes in the guy talks about how efficiency. I recently took my 3 inch down from 3052's to 3028's thinking i'd get more battery life, and instead what happened is that I got A LOT LESS battery life! I needed more throttle to hover, the motors had to spin much faster, I even had to increase filtering because the motors were getting too hot. It was very surprising but in the end made a lot of sense.
From my experience, the RMRC Valorem is my sweet spot for a good racing/freestyle quad. I put the 5mm stretched x arms on that thing and it's been great
Catalyst machine works raging droner is my favorite geometry. I love my 3,4 and 5" slam nasty frames second. I use racing frames for freestyle. Definitely love this combo
Instead of "dumbing down the throttle" with weight or decreasing prop pitch, have any of you tried expo on the throttle? I'm a big fan of light weight for freestyle. A light skinny air cutting frame is key to maintain float. I'm at 450 grams all up on a 6 inch avan bi blade 1300mah.
Is actualy that 7inch quad running 5inch props good in flying? I like the idea to run 6inch frame with 5inch props...i like the way that there is more distance between props and frame...so less chance to prop can hit something
Great vid, I hit like the minute I saw the cast. Alex, I am still hoping to run into you at a park in the metroplex, and as for everyone else - just plain rock on.
I have 2, a 5 & 6"...5" I get 5 mins w punches or 8 mins cruisin on gate breakers lipo rest at 3.72, graphenes 6" Gemfan 6042 tris or 6" gate breakers, they most efficent tris, I've tried tonz. banggood has clones, they pretty good n cheap, not as efficent tho, less pitchy design
more challenging doesnt mean slower, but easier has its benefits! if you control it through the small space youll gain/keep more speed but i understand its a balance, different for everyone. i like the downpitch the prop solution for that, simple functional. i think hes got the right idea.
awesome talk and alot of this is correct because i started off wanting to race but due to issues with my limited amount of travel money it was easier for I to just do freestyle.
Vanover said a stretched X was faster round a track and was more enjoyable to fly. Could a stretched X perform better because the rear props have a bit less dirty air going over them? Dirty air being turbulent air produced by the front props
So to summarise the difference is basically the energy required to change the momentum of the quad-copter, the faster you change the state the less efficient it becomes but in certain applications you need a faster state change so its about optimising the energy required to do that.
If you want a frame that you can use for a little bit of racing and freestyle, use a FlosStyle. Battery bottom OR top, relatively light weight AND not too easy to break.
This was SO interesting for me as someone who builds frames himselfe. I could have used more of that juicy sience stuff! Bardwell ruined some parts where I had to facepalm. I know education is important, but i dont think any newby os going to watch this video, someone that doesnt even know the impact of prop pitch. I missed some battery placement disussion, something about prop durability vs weight, I dont know which camera to use, but most interesting would have been the kind of motors you guys use. 2207 vs 2306? How big is the benefit of light (2204) motors? I am looking forward to part 2 of this discussion!
I use Inventor or CATIA (depending on who I'm working with) as 3D CAD Design software, because I have free student access to them. When I am finished with my frame design, I export the outlines of the carbon parts in .dxf file format. After that I transform those outlines to G Code for CNC milling with the free version of Estlcam and then I cut the frame. Its that simple ;) (jk it was soo hard the first time)
I'm an aviation mechanic and by reading the context clues, THEIR definition and MY definition of "Prop Wash" seems to be two different things. Can someone explain what they mean by it?
Do most freestyle pilots use a go pro or equivalent? I don't really want to watch video of past flights and I don't know anyone that wants to watch any flight so I don't need a big camera just an fpv cam. I was just curious if everyone records and watches their flights or just fly for the fun and experience. Sweet vid guys, thanks for sharing.
The lighter weight is less inertia thing isnt entirely true. Inertia is mass and velocity. So if it a race quad is going twice as fast but half the weight its basically the same inertia as a quad that is twice as heavy going half the weight.(I know that isnt exactly linear but its roughly similar).
Momentum is mass times velocity. Inertia is a quality of matter wherein it resists changes to its velocity. Inertia is proportional to mass and doesn't depend on velocity. (Unless you want to get into relativistic speeds where mass changes as velocity changes, but our quads don't go that fast.)
Thanks for taking the time to discuss frames :-) I still think you guys are missing something, firstly Aerodynamics and secondly the true CG of the drone, the battery is the heaviest, this should be in the very centre of all motor axis.... Having aerodynamic booms also makes the machine track better, it's also 30-40% quieter... You can test this theory with some little bits of foam and tape above and under the boom. Crude but you'll see the difference. Lastly!! a TRUE PLUS frame is MUCH better at just about everything. These X machines, stretch, squished is all just a trend....:-) Cheers guys!! Happy flying !!!!
I have learned so much from you guys and some others in the last 5 weeks. I have been taking my time with my actual build. with that being said...I have LOS dialed. happy with my acro progress via sim. I can fly. likely I will have my first two builds done and flown before summers end. much appreciated yallz
Superb discussion! Anyone tried shorter front arms, longer rear or vice versa to clean up air flow in a freestyle context? Obviously racing angles negate this problem to a large degree
Braap and steez are best! Zack knows what's up! Everyone can argue all they want in the end it's all personal preference and what works best for you. Example, the difference between Le drib and Mr. Steele. Zack is le drib, vanrover is Steele. You forgot to add that a heavier quad with power has more velocity in which you have more time to perform a trick. I personally would go xlabs Braap for race, ummagawd remix for freestyle. 👍
@@aldenhauser9555 per rotation in ideal conditions unloading 100% with no prop slippage in the air (which there pretty much always is a degree of). I think it gets wierd and some props go by literal pitch or advance ratio but plane props and most multi prop go by advance ratio? (Third voice to confirm that pls)
Yes, measuring advance ratios on a static ideal case is probably the best figure of merit, although the way props unload is a huge part of why the different shapes and feel can emerge from different designs. Comparing across the same product line, pitch works really well (or at least within the same overall design family).
I’m convinced now even more with the stater motor size references and all this fantastic explanations about so many aspects. In a year we are all going to be flying and racing combo split HD cams on 4” props on massive motors we would now think proper for 5-6” quads but on ultralight 180mm frames. Someone make,this damn qwaad for me to buy! Serious I’m right aren’t I? A quad with so many amps to spare? And the racer in s blue shirt likes more expo on pitch but doesn’t want to actually have to set the expo on his pitch higher....So he enjoys a stretched X. Doesn’t that make sense? The tech has broken through the thrust weight stability game so I want it now.
im laughing at Vanover jus shaking his head in disagreement with almost every point being made lol
It's like... just be a better pilot. He's right though.
Right in almost everything??? Where he is a great pilot but pilots not always know all whats behind their machines.... t
"I don't use smoke-stoppers cause I'm a savage." Dude is a savant (and is probably right), he's like, 'these nerds talking about numbers', lolol
Agree with the racer. The only thing higher rotor loading is good for is gusty wind. And I didn't even hear anyone mention that.
Can we get an updated hardcore discussion like this again? there has been SOOOOO much advancement it would be nice to see
yes please

The best discussion about quads I've seen to date!!! Great video Guys!!!! Was odd knowing Drib was there and didn't get to hear his opinion on all of this... Liked the format too...
Momentum of a heavy quad will carry speed better than a little quad. Also glide factor of the belly pan of body can increase float.

Short answer: a system of higher order non-linear differential equations

That`s a summary definition of the math involved, not an answer to "race VS freestyle".

Instead of "dumbing down the throttle" with weight or decreasing prop pitch, have any of you tried expo on the throttle? I'm a big fan of light weight for freestyle. A light skinny air cutting frame is key to maintain float. I'm at 450 grams all up on a 6 inch avan bi blade 1300mah.
Casey Dimmitt YUUUUP I'm with ya, all about da float
Is actualy that 7inch quad running 5inch props good in flying? I like the idea to run 6inch frame with 5inch props...i like the way that there is more distance between props and frame...so less chance to prop can hit something
Great vid, I hit like the minute I saw the cast. Alex, I am still hoping to run into you at a park in the metroplex, and as for everyone else - just plain rock on.
Awesome discussion. Love it. Thanks guys.
I freestyle a sub 300g racing frame on 3s 1300 2600 kv and love it
What's your flight time on your setup? Prop choice?
I have 2, a 5 & 6"...5" I get 5 mins w punches or 8 mins cruisin on gate breakers lipo rest at 3.72, graphenes
6" Gemfan 6042 tris or 6" gate breakers, they most efficent tris, I've tried tonz. banggood has clones, they pretty good n cheap, not as efficent tho, less pitchy design
more challenging doesnt mean slower, but easier has its benefits! if you control it through the small space youll gain/keep more speed but i understand its a balance, different for everyone. i like the downpitch the prop solution for that, simple functional. i think hes got the right idea.
Thanks people that was packed with information in a way none super geeks can understand it keep it up
Is there a frame where you can adjust the angle of the arms on the field?
Excellent episode. Had to watch til the end.
awesome talk and alot of this is correct because i started off wanting to race but due to issues with my limited amount of travel money it was easier for I to just do freestyle.
Great discussion guys! Thanks for sharing :)
Vanover said a stretched X was faster round a track and was more enjoyable to fly. Could a stretched X perform better because the rear props have a bit less dirty air going over them? Dirty air being turbulent air produced by the front props
So to summarise the difference is basically the energy required to change the momentum of the quad-copter, the faster you change the state the less efficient it becomes but in certain applications you need a faster state change so its about optimising the energy required to do that.
If you want a frame that you can use for a little bit of racing and freestyle, use a FlosStyle. Battery bottom OR top, relatively light weight AND not too easy to break.
@14:50 is that the hype train I hear in the background?
This was SO interesting for me as someone who builds frames himselfe. I could have used more of that juicy sience stuff! Bardwell ruined some parts where I had to facepalm. I know education is important, but i dont think any newby os going to watch this video, someone that doesnt even know the impact of prop pitch.
I missed some battery placement disussion, something about prop durability vs weight, I dont know which camera to use, but most interesting would have been the kind of motors you guys use. 2207 vs 2306? How big is the benefit of light (2204) motors?
I am looking forward to part 2 of this discussion!
It's very risky to start assuming what your audience already knows, unless you make it explicit. Newbs should feel welcome in this discussion too.
I have some ideas for a frame design, and I want to try and make that possible. Can you give me a run down of the hardware and software I'll need?
I use Inventor or CATIA (depending on who I'm working with) as 3D CAD Design software, because I have free student access to them. When I am finished with my frame design, I export the outlines of the carbon parts in .dxf file format. After that I transform those outlines to G Code for CNC milling with the free version of Estlcam and then I cut the frame. Its that simple ;) (jk it was soo hard the first time)
We need more debate videos like this . So much information !
Very interesting discussion 👍
I'm an aviation mechanic and by reading the context clues, THEIR definition and MY definition of "Prop Wash" seems to be two different things. Can someone explain what they mean by it?
Do most freestyle pilots use a go pro or equivalent? I don't really want to watch video of past flights and I don't know anyone that wants to watch any flight so I don't need a big camera just an fpv cam. I was just curious if everyone records and watches their flights or just fly for the fun and experience. Sweet vid guys, thanks for sharing.
The lighter weight is less inertia thing isnt entirely true. Inertia is mass and velocity. So if it a race quad is going twice as fast but half the weight its basically the same inertia as a quad that is twice as heavy going half the weight.(I know that isnt exactly linear but its roughly similar).
Momentum is mass times velocity. Inertia is a quality of matter wherein it resists changes to its velocity. Inertia is proportional to mass and doesn't depend on velocity. (Unless you want to get into relativistic speeds where mass changes as velocity changes, but our quads don't go that fast.)
short version: best Drone and configurations depends on your dession, right?
Thanks for taking the time to discuss frames :-)
I still think you guys are missing something, firstly Aerodynamics and secondly the true CG of the drone, the battery is the heaviest, this should be in the very centre of all motor axis.... Having aerodynamic booms also makes the machine track better, it's also 30-40% quieter... You can test this theory with some little bits of foam and tape above and under the boom. Crude but you'll see the difference. Lastly!! a TRUE PLUS frame is MUCH better at just about everything. These X machines, stretch, squished is all just a trend....:-) Cheers guys!! Happy flying !!!!
I have learned so much from you guys and some others in the last 5 weeks. I have been taking my time with my actual build. with that being said...I have LOS dialed. happy with my acro progress via sim. I can fly. likely I will have my first two builds done and flown before summers end. much appreciated yallz
yes. do more like this.
Excellent discussion, thanks guys!
This was great! Love hearing the opinions of these great pilots. Only complaint is that the camera was really shaky and kinda hard to watch.
glad you made this
He's right the Avan R is super pitched but totally efficient. I fly them all the time. What he doesn't speak of is how incredibly tough they are.
Great episode guys!
Superb discussion! Anyone tried shorter front arms, longer rear or vice versa to clean up air flow in a freestyle context? Obviously racing angles negate this problem to a large degree
is that race quad using 20x20 stack? any part list?
What 20x20 stack is Vanover using ? I'm interested
What are the excact specs of Alex' race quad?
Awesome discussion guys, It is an educational experience from some of the best FPV pilots out there! LTRIP!™
Has anyone have an opinion on the ImpulseRc helix frame?
Braap and steez are best! Zack knows what's up! Everyone can argue all they want in the end it's all personal preference and what works best for you. Example, the difference between Le drib and Mr. Steele. Zack is le drib, vanrover is Steele. You forgot to add that a heavier quad with power has more velocity in which you have more time to perform a trick. I personally would go xlabs Braap for race, ummagawd remix for freestyle. 👍
NO...Pitch numbers mean how far the prop moves through the air in a single revolution...
SKIDOOSH at what speed?
@@aldenhauser9555 per rotation in ideal conditions unloading 100% with no prop slippage in the air (which there pretty much always is a degree of). I think it gets wierd and some props go by literal pitch or advance ratio but plane props and most multi prop go by advance ratio? (Third voice to confirm that pls)
Yes, measuring advance ratios on a static ideal case is probably the best figure of merit, although the way props unload is a huge part of why the different shapes and feel can emerge from different designs. Comparing across the same product line, pitch works really well (or at least within the same overall design family).
When is your camp coming to San Francisco
I’m convinced now even more with the stater motor size references and all this fantastic explanations about so many aspects. In a year we are all going to be flying and racing combo split HD cams on 4” props on massive motors we would now think proper for 5-6” quads but on ultralight 180mm frames. Someone make,this damn qwaad for me to buy! Serious I’m right aren’t I? A quad with so many amps to spare? And the racer in s blue shirt likes more expo on pitch but doesn’t want to actually have to set the expo on his pitch higher....So he enjoys a stretched X. Doesn’t that make sense? The tech has broken through the thrust weight stability game so I want it now.
