RCX 2306 vs 2207 Motor For FPV Mini Quad | WHICH IS BEST 

U like the 2207 but i thought your flight with the 2306 was so smooth . Yew 👊

Put two Motors on one side and the other two on the other side of a quad and use Black Box to compare there punch out and top-end thrust and torque differences.

Joshua, I was having yaw-twitch problems on two quads with new motors, EMax and Brother Hobby, and found the solution in one of your own 2hr videos from a few months ago. I increased the PWM frequency in BLHeli to 48 and that did the trick. Also, before I increased the PWM freq, the motors were noisy in the Motors tab at certain speeds, but once I increased the PWM the noise cleared up.

Hey Joshua ...I just wanted to say thank you so much for everything you have done for us in this amazing hobby, and congratulations on becoming a new member of Rotor Riot......I think your exactly the pilot they need for future growth and continuing the drone camp function. I always have been a fan of your channel as it has been my trouble shooting guide when I couldn't get my Drone working or if it was working and had a problem..... I could always figure it out because you had a video about my problem .....every time!!!!!! ....without your channel I would have bin totally lost and most certainly would have given up, But because I could always fix my problems by listening to your videos it made it easy to find a solution......thank you again man and you never know maybe we will fly together one day!!!! cheers.

Buddy I gotta say your flying has come a lonnnng way since I first started watching your channel. Great review! 2207's from now on for this fella. Cheers!

Glad to hear, as I have been wondering the difference between the two, and just got a set of T-Motor F60 III 2350s from getfpv, they are on sale for $19.99 each! I have heard good reviews on them, and I like the fact that they are the old style motor with a closed bottom.

Excellent video Joshua. It’s one of those things that are hard to grasp until you experience it. Then so very hard to describe to someone who hasn’t. Nicely done & welcome aboard!

Awesome depth review as always. Thats why I love this chanell so much!

I really like the "idea" of the wider stators over the taller stators because it gets torque from the mechanical advantage which to me seems more efficient. Sciencey! You got me hooked on RCX motors btw.

Since their inception, wider than 22XX on 5" or 6" has always felt lacking in the top end power and control to me. Even testing the Hyperlite 2307 vs 2207, I hugely preferred the 2207. This was most confusing finding to me since they're the same motor other than the width. I've discussed this dilemma extensively with Ryan Harrell of MQTB and there isn't really a clear explanation we could come up with. Comparing a 2306 vs 2207 in terms of power curve, the 2207 definitely has its power band pushed up higher in the RPM range and from Ryan's tests, they do manage higher RPM transitions better as well. With respect to acro, lower pitch props are usually prefered and it makes sense to pair them with a motor that's better in the higher RPM range. I believe the lower pitch props are preferred because they generally 'should' have better overall control and handling since they don't stall as easily. Especially in the lower RPMs. However many steep pitch props these days like the HQ5.1x5.1x3 and original Avan triblade, have design features that are very good at managing this low RPM stall issue and just feel extra awesome on a 2207. But you give up a whole lotta amps for that kinda performance. Emax is testing their 2009 prototypes and finding some interesting results... It would seem that the power band position on the throttle curve is very closely correlated with the motor width and the motor height can expand that band while the kv will attempt to draw it out or pull it in. The part I'm hung up on is that wide motors and high kv don't seem to perform as I would expect by extrapolating from other motors. We've come so far that we're now splitting hairs to fine tune the performance out of these machines. It's awesome

Awesome! I'm just moving up from 2205 2300kv to 2207 2600kv on a budget with the dys samguk wei motors.... Glad I chose the correct size! Thank you for confirming my thoughts and choice... Cheers

RCX motors have always been good for me. They also have replacement bells, bearings, clips and shafts etc so well worth getting the spares when you order. Bearings have also been easy to replace on the one's i have which is handy too.

My first impression (and I could be wrong) is that you need less throttle with the 2207 to do the same. I mean, to get to some high.

I totally agree with the preference of 2207s. Granted my 2306 experience was tainted with the emax 2306 2750s, but a massive difference between the two was noted by me.

Dude your skills have improved tons this past year bud!

OK I have been in electronics since high school, service manager and head tech. at a TV Repair shop ,and all I could say is it looks and sounded like it took less power but more of a punch was the 2207, I also love the RCX Brand more than any other brand for a discount motor. THANKS JOSH ! Looks like I will get these 2207 for my 220mm 5in. frame. have a great week . JohnnyDRC

I prefer the 2306 2400kv motors for freestyle. I like the bottom end torque that they provide. In the end it all boils down to flying style and how you want your quad to feel. Great video JB👍

Coming from a motorsport background your findings make perfect sense to me and are what I would expect to see too. In combustion engine terms. Wide stator vs narrow stator of the same displacement could be thought of as a 'long stroke' (narrow cylinder) engine vs a 'short stroke' (wide cylinder) engine. Short stroke will be less torquey but typically rev higher (lower mechanical stresses) and have greater potential power higher up in the rpm range. With a wider stator you have more mechanical leverage which suits it well to low down torque and efficiency if you operate in this area of rpm... but if you want top end power you are better off with a wider magnetic flux ring.... akin to the wider flame front in a short stroke racing combustion engine. Although they show similar bench test static thrust figures... the 2207 will typically unload more and therefore rev higher in free flight and this is why it feels better in real life.

Sick ! Man, love the new maneuvers.

Using both. My race build is sett up with 2207.6 on my Hyperlite Floss 3.0. On my source one v3 freestyle build I'm flying 2306. They both fly amazing. For awhile I had them the other way race build had the 2306 an freestyle had the 2207.

nice flying man, the rotor riot growing in you ;) and thanks for the comparison of cause.

I'v used RCX motors for 5 year now and they are the best value motors in my opinion. They just came out with the LS2207 series which are even cheaper but still pack a sick punch.

Video summary at 14:40 You rock Joshua :D

We'll thanks Joshua now I want a set of 2207.... can't afford them, but if Joshua Bardwell says they're better they're better... you're my Fpv idol bud striving to be as knowledgeable as you. .

New proffessional intro is spot on. The UAV futures arms in the air was kinda funny heh

i tried 2306 meny models, emax, rcx, dys... And all have one thing in common, if you want to push it it sucks the battery down when over 2400kv. 2207 2300kvish is a softspot for me, plenty of power, plenty of prop choice and flight times are incredible. Keep an eye on 2305 size, seems to be the new sweet spot with 2350kv and 2500kv.

Good stuff Joshua Bardwell. One problem though. Volume of a cylinder is pi*r^2*h, not pi*d^2*h. It doesn't really change the comparison, but your numbers for volume are off by a factor of 4.

Thx JB! Idea for the video editing: cut amp draw and throttle from osd DVR on top of the GoPro footage.

Great video! I have to agree with your explanation :) the 2207s have natural expo throttle curve in my opinion. An interesting test would be to adjust the throttle curve on the 2306 to match the quality of the 2207

I have both of these exact motors. The 2207s rock! They just released an "economy" 2207 for 9.99. Maybe different magnets? But I dont understand why people try to steer you away from 2207 motors. They are perfect for the way I fly. They have amazing torque so they are great for quick movements. But I did notice that I dont get as much flight time with the 2207s. Great video!

Thank you so much! Was just wondering about this...

I've been waiting months for this video! And I already came to my own conclusion. 2207s rock! For a cheap motor these things haul ass! Two blade 5046 gemfans these things pop!!! Amazing thrust and good flight times! Thanks for the good comparison!

nice, always depends on the setup and weight of your kwad, i switched motors a lot from quad to quad to find out what works, i had the best results with lightweight with 2207 and light props like 5043HQ and heavy quads with 2306 with props like cyclone 5046C

Great video. I switched exclusively to 2306 engines. Find these much easier to tune. I also like the sound and torque of the engines. With 2207 I had too much rattling on the engines. But I have to say that they have always had more KV than now with the 2306th I am the opinion that 2306 with 2500kv better and more precise fly as 2207 with 2700 kv. I fly now only Emax and T-Motor engines and have only had good experiences. I think your test is great, but also on your flight videos, I think that the 2306 engines run better.

Great Review! now all 2207 motor will be sold out this weekend

been running some cheap motors but a good motor at the same time, DYS 2207 2600kv and 2206 2700kv and I'm loving these motors and super price at $10 each

14:42 that would make sense since they have a smaller moment, or rotating inertia since the weight of the bell is brought in closer. You could try adding a bit of weight with copper tape to the motor and see if that takes the advantage away maybe?

I thought I had a really clever idea, but I was backwards! I did the same math as you, but I also subtracted out the volume of the bearing to get closer to the volume of the actual windings. Surely the volume gap between the 2306 and 2207 would appear even bigger then, right?! Nope. This is where I was backwards. Instead of your 7% difference, I came up with a 5% difference.

my b hobby 2207's are great. if you want to full stick it, they go. if you want to freestyle, they pop. samguk wei's are also great. just not as immediate on the stick. using higher kv 2600 or 2700 you notice the difference in torque. 2306's are also great but I havent spent the money on top end motors in this size. my preference has been the 2207's, even over 2307's. the difference in performance wasnt much but the battery usage was radical. thanks for posting.

100% my exact findings between 2306 and 2207 on other brands as well Josh. Literally. I get longer flights with 2207 even though the amp draw is slightly higher as well and I think it’s due to the higher torque and faster speed of the quad that I don’t need to be on the throttle nearly as hard. I find on 2306 I need to be on the throttle a LOT more and my flights get very short. I love 2207 and will never buy more 2306. You literally mirrored my exact findings between the two motor sizes, even your descriptions of the two. Thanks again and great thorough testing!! - Travis

I like the 2207 of ur video comparo, but the inverted 360 with the 2306 sold me!

Interesting to back and look at this and reading the comments after Chris Rosser entered the scene :)

I went from 2207 to 2205 and was surprised how much performance this motor has. Well my build is pretty lightweight too. Handles like crazy!

nice flying looks like you have leveled up

I LOVE that RCX 2207. Massive fan

@Joshua Bardwell I would describe your quads as "stiff but dampened". This is just my best guess from watching your videos for a couple years. In other words, your tuning seems to be very active to hold attitude, but then dampened to eliminate all P oscillation. Most other quads seem to have a tiny bit more oscillation and prop wash. You hate prop wash with a passion, but you deal with it when there is just no way to get rid of it.

Good video. Yeah I love the 2207 style and I really love the t motor f60pro2

I could tell that you were up higher in the video with the 2207. Just because that happened to me when I lowered my cam angle. All of the sudden the thrust I was used to giving shot me way up in the air. Kind of the same way more thrust = more height in the flight.

The most important of all you mention, is how you finish you winding on the motor and is the 6 terminals, start or delta, that means you want a low kv and more torke or hi rpm or kv and less torke.

agreed i just went from johhny motors (2207 2700kv) to le drib motors (2206 2650) i can really feel the power difference, 2650 was the highest i could get locally as getfpv was out of stock... still like the drib motors but miss johhny's motors. i even went back to 2450kv motors that i still had and nearly cried

I recently purchased the f-40 pros and the f-60 pros which is a 2306 and a 2207.. I never felt the low end torque on the 2306 like you would think. The 2207 always felt more responsive and torquey but didn't have the top end speed the 2306 provided. And when flying with a go-pro I always go with a 2207-2407 so that I can't tell the go pro is on the quad. So.. top speed=2306... 2207=immediate response, torque and speed with out the top end of the 06'.

Finally ur doing yaw flick moves. U should do a trick video on that! No one has ever done a yaw flick video and Johnny gapit and willy would be proud

Fpvmodel hurricane 2207 and miniquadtestbench gave it a thumbs up. Similar price point. There is also the BBB 2207 and rcaddict love them for the power and smoothness.

Totally agree with you. I had the F60 Pro II 2700kv on my quad and switched to the F40 Pro II 2400kv. With the F40s I always have the problem that I hit the ground when diving because they miss the pop I have with the F60s. On the F60s when I think I'll hit the ground and raise the throttle I'm just skyrocketing into the sky.

I prefer this new intro speech instead of "...you gonna learn something today" nice video

Yes I tried the emax 2306s and they were beastly at every level. But I have settled on the emax ls 2207 2400kv and love them. Thanks for the videos JB! Anxiously waiting for the rapidfire module review!

2207 has a faster response to throttle input due to the stator width. The height of the magnets allows you to run more aggressive props without “over-propping” your motor. 2306 is going to have an easier time spinning 6” tri-blades than a 2207 or 2208 motor. It’s like a gear in a transmission. The smaller the gear, the less torque can be applied to the driveshaft. The wider the gear, the more torque can be applied. Torque is required to spin larger/more aggressive props.

I am curious about how superlight motors like the NK2204 actually perform compared to heavier, more powerful motors. This line of motors is great!

Engineer's answer- ANGULAR MOMENT- basically you have more "stuff" further from the center. AND the SAME tangential force is at a larger OD. The difference goes back to PI, or ~ +3 times on RADIAL difference. So just a little bit of diameter goes A LOT further than a linear iterpolation. Thank you very much

Love the 2207 with 5S. I still feel like a small increase needs to be in-between the 22 and 23 (maybe a 22.3) and would like to try 08 again.

I could hear from the noise You were riding your throttle more on the 2206. A little rev up on the 2207 threw you over the trees while it was a climb on the 2206. I agree with your assessment. Love the 2207s. I also love the low throttle power of the 2207. So question. Is this equation correct . “ if JB likes = I likes then I am #NerdLikeJB”

Holy Moly! That was the real life Liftoff scenery!

I definitely feel like the RPM range (an related weight/loading/advance ratio of the props) end up dictating that quite a bit. I can absolutely see why freestyle at lower speed the control of the wider stator is impressive and feels great with the right tune, while 2207 keeps the torque all the way up to the top, which is why many racers and even freestyle pilots who prefer lower pitch props will favor those. Efficiency is the other bigger question - I think it'll match the above that taller stators are more efficient at higher RPM, while wider stators are efficient down low and don't have to work as hard when changing RPM larger amounts. On thrust stand, that shows higher RPM torque delivery of taller stators - I think a more comprehensive motor dyno would show that the wider stator is going to be more responsive at a minimum - looking at Ryan Harrell's 0-100 ramp in RPM and Thrust definitely seems to show that behavior. I think running lighter prop pitch in 5" weights (~4g) negates most of that difference, and then the 2207's torque delivery being more linear higher up the RPM range (flatter torque curve) is going to feel a lot better all around.

hmm, weird. from the two videos I would have placed my bets on the 2306s. it looked a tad smoother and the motor sounded less chirpy. I thought I heard a slight chirp from the 2207s and saw slightly more vibrations coming through, figured it would be slightly off I gain maybe? Maybe I am imaginng things... Love my Emax LS 2207s though.

I hear you JB 2207 FTW! ❤️

We’re all glad there is one:)

2207 ftw. I hear the difference verry clear in the videos. I hear from myles far when a 2207 is in the air. I have some 2308's 2700kv,s here and these also give that same feeling as the 2306. Some smooth linear/lame feeling, powerfull af but still they dont give that poppy agressive feeling like a 2207.

Your flying is getting better dude, you don't suck as bad as used to lol 👍

This is why I fly 2307, I get all the linear feel of a 23XX with the aggressiveness of the 2207, they also only weigh 30gr. I also have 2506's, those run cool and slick as ice, but my 2307's still have more rip- I mean seriously, they are scary fast, max amp draw I've seen so far is 90A so not terrible.

Great video thank u i was under the impression that 2207 are for 6" or bigger drones I build a 5" and I use 2205 and in the second build also getting me 2205 . But if I can use 2207 on a 5" cool

Awesome Video! 🍻🍻

Hi Joshua, great job done I'd say. Do you plan to make such video also for motors for 7" quads? I mean for free style or long range kind of copters. Or in this case it does not matter so much? Currently I am using in my 7" LR quads 2408 motors (Hyperlite actually). but there could be also some other motor size options, what do you think? ;)

What would we do without you JB?!! 😎

I switched to 2207 last year and I am still running 2207's... there is something about the throttle curve on them that just feels right.

The RCX LS2207 in no-warranty trim has been fantastic for me - unless the durability is junk (so far 9 packs on one quad), then I've found my new motor for everything. In 2400KV (4S) and 1700KV (6S), I don't know what more to ask for out of lighter quads. The fact that I can slap together builds with mostly decent parts at

Oh yeah, I was wondering what happened to this video! Interesting that 2207 feel better, I always imagined they would need higher kv and as such higher amps to do the same as 2306

Hello JB. Had to say I really liked your 2306 motor flight. some nice moves you did there . May I ask which battery you ve used in that flight ?

Did you need to tune the quad differently for the different motors

Thanks again JB

I've had good luck with dys shu 2306 2500kv motors 10 bucks each, but you make me wish i picked the other dys motors lol. The biggest Motors I've ran previously were 2206 I was expecting a massive power gain and there is more power just not as much as I expected.

I know that sounds does not matter, but guys am I the only one that loves the sound of 2306?? 😍 Much more than the 2207. Feels power

You should try the DYS samguk series, budget motors and I love my 2207s

what makes butterflight different from betaflight? I just tried it on my F3 at 4k/4k no kalman filter and set them up pretty much identically but butterflight felt different and the footage was noticeably smoother.

Thanks (again) for learning me something today, what props did you use JB?

I’ve been seeing some 2506 motors used on 5-6” builds. What would be the benefits of such a large motor on a smaller quad? Is there a situation or application that would justify the weight?

Looks like the 2306 RCX's have suffered from the Bardwell Effect - wiped out of stock at RCMart since May! (in reality seems it's a bearing supplier issue). Next best suggestion in similar or slightly higher price range?

I also noticed that my rcx rs2206 motors run hot to the point that it is hard to raise D above 35 or turnoff filters

Next JB todo list: ESC amp/responsiveness testing for comparison (and finding yaw twitch reasons/potential noise reasons) ?

you should try the 3b-r 2207 2650kv, there about $15 and ! Best value for money !! they are one of the best motors i have ever used

2306 is working better for me 😎🤘🏽

Im testing the same two sizes of motor currently and i have to agree, i prefer the 2207 they just "feel" better.

Surprising. I thought you flew more confident with the 2306.

Great job!!!

it depends which brand you try and how they make it...I like the Brother Hobby 2306 R5...the 2306 have a bit more torque in the low end which feels better for freestyle IMO...hence most of the freestyle motors being this size...hypetrains, steele, more popular T motor F40 Pro 2...etc...but some do prefer 2207 high kv...

Nice video lad

I like this feelings video, man.

Lovin the 2207s personally

the cobra 2207 2450 are some of the best motors ive used, especially on 5s. Also i have that same yaw twitch issue, ive tried everything, did you ever manage to fix it?

Damn, it's like you read my mind JB, thanks mucho

I have two (nearly) identical quads, one with TMotor F40 Pro II (2306), the other with TMotor F60 Pro II (2207). To my surprise, 2207 felt......soft, slower to respond to inputs. Doing identical dives and coming out of the dive at identical spot, 2306 made it out no problem, 2207 didn't recover quick enough and made a contact with the ground. Flying 2306 felt like Cyclone 5046 props while 2207 felt like Cyclone 5040. 2207 has a strong top-end, it's just feels that it takes more time to get to that top end while 2306 feels a lot perkier. This does follow the notion of 2306 with more torque and 2207 with more top-end. Would you mind asking Ryan Harrell to test F60 Pro II, so that it can be analyzed side-by-size with his F40 Pro II test?
