Why you tried with different props?.... The prop is what dictates the power draw, grip in the air, speed... etc... (put a 2 blade old gemfan 5030 and they will say OMG there is no power!!!)
Umm this may be a late comment but again great episode! Honestly there IS a significant difference between 2306 and 2207 at the same KV. 2306 is more linear, has better low-throttle performance, but drain batteries faster. 2207 has higher top end speed, slightly more efficient, but doesn't fly very well at low throttle. (All with the same props) If you are used to high throttle flying, 2207 is a much better choice than 2306, especially on 6s. But if you just started to learn racing or complex freestyle, 2306 is easier to control. Results might vary depending on the motor manufacturers. I'v only tried rcinpower motors and iflight XING motors before making the above conclusion. BTW the new DALPROP t5046c is absolutely amazing so go check it out lol..
Many thanks folks, this was again a real good RR episode: Very entertaining and we all, who do not own 2207 and 2306 motors with the exact kv values, learned a lot, imho. It was really surprising to me that both motors, with the same kv, actally seemed to feel pretty much the same. I thought, that you would feel the faster accellerating 2207 for sure. But I only own 2207 2700kv and 2306 2450kv of BH. And these are not comparable. - Everybody feels and hears! the difference immediately. I chose those motors for a reason: The 2007 2700kv spin up extremely fast and therefor have extreme response. Which is great if I like to fly in "wider" areas. And they so easily throw your quad... sometimes almost too far ;-) - Pushing the throttle up fast does not cost you many amps if you fly for example the skinny T-Motor props, I also love them for that motor. A lite quad with these is a beast! - And lot of people seem to love to fly them with much throttle-expo (for the gain in low end resolution). The 2306 2450kv spin up slower, but also with torque, are more forgiving to nervous throttle control and you have to accellerate them a bit slower and more linear to get your punch. Otherwise you'll burn amps - I love these for smooth freestyle and also proximity on a small space because the are not fast enought to react that immediate if you overshoot a little bit in your throttle reaction. Why do the 2207 spin up faster and why do 2206 have such a nice smooth feel? * The 2207 spin up faster because the stator is not that wide, so the swinging mass (the bell) to be accellerated is less. (probably not the perfect description but I hope you get what I mean) * The 2306 spin up slower because the stator is wider, so the swinging mass (the bell) to be accellerated is more, but when it once is accelerated, it keeps it's accelleration pretty stable, which makes it more forgiving to nervous throttle thumbs. The flighttime when I fly the quads with the described motors is pretty the same. - But I also fly those different motors very different. - The 2207 more agressive and the 2306 possibly as smooth as I can ;-) And this episode made me interested in some 2306 2700kv, perhaps the golden middle for me? Or maybe 2207 2500kv? - Maybe those? (Damn, then I have to buy spare motors for three types... that's not good:-) Again, well done, I loved this episode: All tumbs up!
I notice a difference in motors and profiles in 4S, once you go with 6S, it really levels the playing field, you just pick based on quality, price and the styling you like. All that said, I like 2306 the best, 2207 and 2307 suck more amps for almost no extra performance- they also hold on to heat longer.
Well, at lest they scienced their way to the actual answer - prop pairings dictate most of the feel, and that variations in battery performance are going to be more substantial than minor differences in stator size when you're not flying all out. Lighter props that can spin up faster are going to be generally better on tall stators, and can linearize thrust delivery on some setups. For most beefier props that tend to have that 'creamy' feel, the wider stator is going to feel much better, with a lot of the torque delivery happening at low to mid throttle. On those props, I'd probably choose 2306, but for what I run the answer is 2208 motors all day every day.
tehllama42 agreed. When you get to the 2207 and 2306 size I feel it’s all preference. But props have a lot to do with it. Now for freestyle I’m with you on the 2208’s. I love my Xing 2208 1700’s on a wild Willy dolphin frame.
@@archer4922 If you want to run slightly porky race quads (very wind-resistant), those same motors are amazingly good. Definitely excellent for GoPro haulers as well
Please please please do more of these. Blind comparisons are so much more meaningful than numbers on a data sheet. I'd love to see a comparison between say the XING and XING-E, or similar comparison between an "economy" motor and the luxury model with identical stator size.
Like the video and nice to see a comparison but not all motors with the same size and if are the same. I run 2306 2450 on the same frames with the same internals and props and the brother hobby r6 have way longer flight times than the hypetrains, with more initial grunt.
Love this. Blind test is better than science. Alex is right about running the spreadsheets for race results, but four reports of what each pilot felt was way more interesting. Thanks!
Fun video, and I appreciated the info. Fun science is the way to go :) Man! every time I watch a rotor riot video I wish I fly 5in so I could join the party... but then, every time I fly my local park and someone says that my quad doesn't bother them,... they didn't even hear it... Im glad I fly 3in. :)
Great conversation to hear. Go enought test for me i think. Maybe same test (motors and quad) but with the Jamie's Props. I was just upgrading my motors and at least this gets me a bit closure to seeing that from what you all were saying and Vanover's racing info, it's still more of a preference thing. I really wanted to just choose a motor, buy a few and be done with it. But I guess I'll just have to 'try' a few different ones to find out.
There's a pretty easy way to choose between them if you're on the fence. If you have a lighter quad, 2207 will give you great performance without killing your batteries too much. But if you have a heavier quad, 2306 might be a better match to carry the weight more efficiently and give better performance.
You're absolutely right that's actually called a double blind study. So for example the administrator of the test would not know what the motor size was either
Let's hear it for "Bro science"! Daitch here is right! Double bling means neither the subject(s) NOR anyone on the research team knows which is real and which is the placebo.
Muy buena prueba para todos los simples mortales que se la llevan peleando que son muy diferentes como se sienten los 2207 vs 2306 solo por ver videos con opiniónes
Great fun review, always preferred 2306 over 2207 for freestyle, but prefer 2208 1800 6S for the last 9 months, whatever keeps it worth flying I guess👍
Great video! The motors seem even bc dribs are actually not 2650kv they test a little higher around 2700kv+ that plus the 22 size stator struggling with the heavy quad weight and pulling more amps evens them out. Everything can be explained with science!!
Van is slowly becoming my favorite pilot..... sorry drew. for real though I like to way you two interact with each other on camera, its a great mix of personalities.
Drew's expression and the heartwrenching music when LSF was "dissing" his motors were priceless. Was the expression scripted? 😉 So these guys are all so good that they can fly rates other than they're used to that well! Hrmph! 😉 Showoffs! 😉 Naw, great episode guys (and of course Foxy whom I'd sorta call one of the guys...in the good way as in she's their equal in every way. My, it's a challenge to try to offend as few as possible while clowning)! You may not have come up with some huge revelation, but it was entertaining, well shot and produced and a fun watch! It might be lame to like RR 2.0 these days, but you kids are growing on me and guess how many effs I give about appearing cool... Nicely done! 😁👍👊
I loved my dribs that 2306 was the fastest motor I've flown on 4s yet!!!They burnt up in a crash,I'm testing them now to see if they survived.if they did there going on another quad...
14:30... LMAO (the face image plant). Side note: to add some validity to this type of entertainment, run a BlackBox of a full flight on each "identical" quad. If the raw noise is the same and all of the BF settings are the same, with the same equipment, then it can be an A - B test.
I have a full ledrib skyeliner dal5046 setup and a full vortex Bandolero Tmotor 5143 setup. My LeDrib definitely gets longer flight times by over a minute longer. The bando flies amazing but I feel way more confident with my skyeliner.
First off. You can always tell the difference in the sound. 2306 are much higher pitch screamers. 2207 is more of a lower scream. I have only ever ran Dribv2…..still wondering if I should try different ones.
2306 for heavy load and 2207 for lighter quads. EDIT: I like every RR pilots because they are so different and that makes it interesting (Alex is very funny when he's cheeky with Drew and Drew just let him get away with it by just take a harsh look at him)
No one can tell me that ANYONE can consistently tell the difference between a top spec 2207 and top spec 2306. The power in flight is nearly identical and (on static thrust tests there may be a 50 to 60 gram thirst difference between the two in a perfect world but in flight it's nearly identical so long as the KV is the same and the build is the same other then one is 2207 and one is 2306) response is nearly identical, torque is nearly the same, top end is nearly the same you just can't tell a difference... On two identically built race quads with one being same brand and build quality 2207 and one being 2306 with same KV then a world class race pilot may see a slight difference between the two if they ran 20 packs with each motor around the same track and avg the lap times... It's it's a tighter track they likely would see slightly quicker lap times with the 2306 as there is slightly more low and mid throttle torque/response and if it's a bigger track with a longer straight they may see a slightly quicker avg lap time with the 2207s due to the slightly more top end power. In the end it would be so close it wouldn't matter.
Only difference I've noticed is the throttle at the lower end is more. Linier on the 2207 compared to more mushy or that you have to move it more to get what you wanted out of it on the 2306. .. but you'd get used to each
IMO the Captain's opinion was distorted by the fact that he was flying freestyle which throttle play at lower range most of the time. So like puching from 25% to 80% and, rarely 100%. But for racing throttle often play at 40% - 100%. With that high throttle range the 2207 would shine.
I think you would definitely be able to feel the difference if you were flying 6s lower KV. With high KV 4s motors I think the only way you could tell would be amp draw. The feel would be the same just one would sag faster.
I fly 2600kv F40 Pro II and IIIs on 4s builds and F40 Pro II 1750kv on 6s (this is Fpv_diva) I used to fly BH 2207s and F60 pro IIs and i gotta say 2306s just feel better to me... They fly cleaner and easier to tune on any 2306 build vs 2207s... I've also used the Emax RSIIs RS2207 and RS2306. The very top end power may be slightly more on the 2207s but the low and mid range response is better on 2306s and the top end isn't handle anymore on the 2207s.
Engineer here. If both motor don't draw the same power, then this test is kinda meaningless. I'll assume that they both draw the same power with the props as tested. Additionally both motors claim the same back EMF (kv rating). Brushless motors generally have a very linear torque-rpm curve (Unless the designers really messed something up). Given that both motors have the same Kv rating, they should have identical torque-rpm curves. This means that they should have identical steady state output response. What might be different between the two is the rotational inertia, and efficiency. If one motor has a lower rotational inertia, it might be able to spin up the props faster than the other. I.e. it might have a faster transient response. Additionally, if they have different efficiencies, then one motor might run cooler. Different temperatures will have an effect on performance, as resistance rises with temperature. The only way to know for sure would be to put the motors on a dynamometer and test them under controlled conditions. Personally, I doubt there's much difference, and I'd go with the lighter motors.
This is so fun, cause I actually learned about this in class! With electric motors a wider stator/wider bell producers more torque, based off the theory of how current induces torque. A taller stator/ introduces more wire with current, which produces more induced force. Force is different than Torque. In the sense Le Drib motors have more top end, and Vortex motors have more torque. Greater torque is most useful in maneuvering, but find a niche in speed with a bitey prop. Greater force obviously finds the best uses in speed. One thing though- widening a stator increases torque more quickly than force is increased raising the height, since torque is square proportionate to width, while force is more proportionate to turns on windings.
The theory, all else being equal: current is proportional with stator _volume_, and torque is proportional to current. All else being equal. The nominal stator sizes differ in volume by 6.5%. This seems almost insignificantly small compared to other known differences (different props!), but the same proportional difference applied to Kv is 2935 vs. 2750, which seems a big enough difference we should be able to feel. (Yes, yes. They would wind them different, of course. The relevance is Kt (torque coefficient) in metric units is exactly equal numerically to Ke . Ke being Kv expressed as V/rad*sec , rather than Kv's rpm/V. You can and should ask your prof to confirm that.) I don't know if I can feel 5% to 10% difference in torque delivery near mid-stick. Certainly, I don't have nearly the same sense of feel Le Drib evidences in his flying, so maybe he really is feeling the motor. My guess, though, is still that the difference in props far overwhelms the difference in motors.
Michael Young most normally probs would obviously have a bigger effect on feel, considering that these are aircraft of course, but for a given flight style and given prop then the motor comes into play immensely, being the heart of the movement
Skyeliner is my heaviest quad with shorter flight times. That sacrifice is worth it though. I can slingshot it further for that floaty airtime over trees and rooftops.
The problem is that whilst there will be a small difference there will be a larger difference caused by battery placement and power output even on identical battery's.
The bigger diameter the stator is the more the torque it has due to bigger stator having more leverage to pull the magnets round and the longer the stator the more top end power due to there being more surface area of the stator to pull the magnets round if you were to over prop both motors and punch out to half throttle that’s where you may see a difference and that’s where the 2306 would come out on top
I think the reason why Vanover got it wrong because 2207 feels better on a light frame and kinda sucks on the low end of a heavier quad. 2306 feels more powerful on a heavier quad I think.
Please do a PPM vs Ibus vs Sbus blind test (AT LEAST ppm vs sbus OR ibus..... I really REALLY wanna know if people can tell the difference between PPm and iBus

I think the moral is to pick a setup, and stick to it long term. You will fly better and become more comfortable with that setup.

IMO the Captain's opinion was distorted by the fact that he was flying freestyle which throttle play at lower range most of the time. So like puching from 25% to 80% and, rarely 100%. But for racing throttle often play at 40% - 100%. With that high throttle range the 2207 would shine.
I think you would definitely be able to feel the difference if you were flying 6s lower KV. With high KV 4s motors I think the only way you could tell would be amp draw. The feel would be the same just one would sag faster.
Most enjoyable ...If I had ether one of those motors to fly it would change my F N life.A man can dream.
that vannover entrance was fuckin hilarious!
this was the best episode EVEr, i mean the topic was shit, but all so hilarious dudes :D
Bro Science 🧬 😂 Good video guys
Just saw this and feel even worse for asking for the 2207's hahahahahaah I
I have both Stingerswarm 2150kv and Ummagawd 2150kv. On 5s and 6in I like the way the Ummagawd 2306 feel versus the Stingerswarm 2207.
I fly 2600kv F40 Pro II and IIIs on 4s builds and F40 Pro II 1750kv on 6s (this is Fpv_diva)
I used to fly BH 2207s and F60 pro IIs and i gotta say 2306s just feel better to me... They fly cleaner and easier to tune on any 2306 build vs 2207s... I've also used the Emax RSIIs RS2207 and RS2306. The very top end power may be slightly more on the 2207s but the low and mid range response is better on 2306s and the top end isn't handle anymore on the 2207s.
I love him trashing dribs controls at the end
Good one. 2306 or 2207 draws more amp??
i switched from 2206 2450kv rifle motors to 2306 2700kv t motors and love the 2306, I feel like I have more control at lower throttle.
Engineer here. If both motor don't draw the same power, then this test is kinda meaningless. I'll assume that they both draw the same power with the props as tested. Additionally both motors claim the same back EMF (kv rating). Brushless motors generally have a very linear torque-rpm curve (Unless the designers really messed something up). Given that both motors have the same Kv rating, they should have identical torque-rpm curves. This means that they should have identical steady state output response. What might be different between the two is the rotational inertia, and efficiency. If one motor has a lower rotational inertia, it might be able to spin up the props faster than the other. I.e. it might have a faster transient response. Additionally, if they have different efficiencies, then one motor might run cooler. Different temperatures will have an effect on performance, as resistance rises with temperature. The only way to know for sure would be to put the motors on a dynamometer and test them under controlled conditions. Personally, I doubt there's much difference, and I'd go with the lighter motors.
"you werent talking about smelling motors" hahahahaha 14:30
Nice Vanover intro @ 12:45
This is so fun, cause I actually learned about this in class! With electric motors a wider stator/wider bell producers more torque, based off the theory of how current induces torque. A taller stator/ introduces more wire with current, which produces more induced force. Force is different than Torque. In the sense Le Drib motors have more top end, and Vortex motors have more torque. Greater torque is most useful in maneuvering, but find a niche in speed with a bitey prop. Greater force obviously finds the best uses in speed.
One thing though- widening a stator increases torque more quickly than force is increased raising the height, since torque is square proportionate to width, while force is more proportionate to turns on windings.
The theory, all else being equal: current is proportional with stator _volume_, and torque is proportional to current. All else being equal.
The nominal stator sizes differ in volume by 6.5%. This seems almost insignificantly small compared to other known differences (different props!), but the same proportional difference applied to Kv is 2935 vs. 2750, which seems a big enough difference we should be able to feel.
(Yes, yes. They would wind them different, of course. The relevance is Kt (torque coefficient) in metric units is exactly equal numerically to Ke . Ke being Kv expressed as V/rad*sec , rather than Kv's rpm/V. You can and should ask your prof to confirm that.)
I don't know if I can feel 5% to 10% difference in torque delivery near mid-stick. Certainly, I don't have nearly the same sense of feel Le Drib evidences in his flying, so maybe he really is feeling the motor. My guess, though, is still that the difference in props far overwhelms the difference in motors.
Michael Young most normally probs would obviously have a bigger effect on feel, considering that these are aircraft of course, but for a given flight style and given prop then the motor comes into play immensely, being the heart of the movement
I thought 2207 was going to be the clear winner. But I'm still with the Captain & Vort3x on this ;)
drew totally knew which one he was flying ;)
Can someone tell me where I can get those fatshark goggle pads? They look so comfortable!
How can cpt vanovers setup be much lighter than ledribds? Are the seperat esc's much heavier?
much lower weight frame, micro cam
@@astrofpv7035 how much does the skyeliner weigh? I thought mini sized cams were gone with 2018, lol 😂
Skyeliner is my heaviest quad with shorter flight times. That sacrifice is worth it though. I can slingshot it further for that floaty airtime over trees and rooftops.
Haha I agree with the Captain. 2207.5 is where it's at.
2:23 I wonder what date this vid is taken, i don't recall remembering seeing this while watching joshua's stream :P
L00n3y2010 i think they staged it. He’s wearing a rdp shirt and headphones tho so that would have been the May 5th stream
17:26 let the video on pause
me when I find a nice bando be like
Didn't y'alls parents teach you not to talk over someone lol great vid guys :D
Tried both, prefer drib but mostly because it fit my flying style better but also my quad is lighter than both.
Also it's weird Drew the engineer hates spreadsheets.
Hypertrains are on fire😎👊🤘
The problem is that whilst there will be a small difference there will be a larger difference caused by battery placement and power output even on identical battery's.
The bigger diameter the stator is the more the torque it has due to bigger stator having more leverage to pull the magnets round and the longer the stator the more top end power due to there being more surface area of the stator to pull the magnets round if you were to over prop both motors and punch out to half throttle that’s where you may see a difference and that’s where the 2306 would come out on top
I think the reason why Vanover got it wrong because 2207 feels better on a light frame and kinda sucks on the low end of a heavier quad. 2306 feels more powerful on a heavier quad I think.
Please do a PPM vs Ibus vs Sbus blind test (AT LEAST ppm vs sbus OR ibus..... I really REALLY wanna know if people can tell the difference between PPm and iBus
bro really asked scout from tf2 to guess a quad motors
That's cool, buddy
2306 for the win, less amp hungry, less voltage sag, longer flight times & more responsive
“I can smell the difference” LMAO
Sync clap. :D
Useful to know. Nothing really in it, narrower is best for freestyle then! I've dented more 2306's than 2207's (although I am crap).
Bardwell makes every video just alil better imo.
Here is what you should have done. While changing the drone, put a new pack on the same exact drone, and see if they can make the difference
