Can a 3" B3AST be my favorite FPV drone? The small but mighty 6S Quadmula Siren F3 Split build

It may be small, but it can still rip FPV freestyle with the best of them! This 3" B3AST build is packing a huge amount of torque, full 4k on board recording, 1080p HD pilot feed, a high amp ESC to keep the 6S power flowing, and all of the modern features of its bigger brothers. Don't let it's size fool you, it doesn't play.

Im working on a 3.5" ripper right now, id love to send ya one when its finished.

[@BaconNinjaFPV]

I have been waiting for you do to one in that size! I always loved your little rip squeak vids, and with the Demibot coming out I figured it would just be a matter of time until you got something going in that size range. I would absolutely love to take a look at it when it is finished up! Also....gonna have to put a bratwurst or something on it and see if it can carry that :p

[@Arbi5577]

I built a Quadmula siren f3 o3 as my first build after watching your video on it! Such an awesome quad. I accidentally got the regular siren f3 instead of the split but actually worked out since I had more room with the skystars FC. The cap was a pain though.

[@BaconNinjaFPV]

It is a great little rig!! The non-split does have a bit more room for sure...but that cap man, every time with that thing, lol.

[@2_damn_fly]

I built this and have been enjoying it quite a bit except for the broken props on every crash...switching to 3 blade props today and looking forward to some airtime on larger batteries . Thanks for the update. Super helpful

[@BaconNinjaFPV]

yeah that is exactly the reason I moved from the 4 blades. I really did like the 4 blades, and the extra thrust and grip really did feel nice....but literally every crash meant a broken prop, lol. I bet you will like the 3 blades better when it comes to that!

@@BaconNinjaFPV test flight today! I also stuck a flywoo Goku gm10 nano gps chip on the back.

[@rubengarciajr7560]

@@BaconNinjaFPV how come the 4 blades breaks, as opposed to the 3 blade ones?

[@BaconNinjaFPV]

@@rubengarciajr7560 good question! A 4 blade prop has less area for connecting the blade to the hub since it is shared with more blades, which makes them weaker. Also, a 3 blade prop can move out of the way on impact ( 2 blades are actually best at this ) where with a 4 blade you are more likely to put leverage on a blade instead of the arm in an impact.

[@MCsCreations]

Awesome build and flight, dude! 😃 Those little quads are a heck of fun! Stay safe there with your family! 🖖😊

Thank you buddy! I love that I can just throw it on a bag easy then bust it out and rip without ticking anyone off and even in small spots.

[@sixtofive]

Reminds me of a 4" build I did a while back using the original fpvcycle 2203 3450 kv motors. 850 mah 4s turned out to be the sweet spot for batteries, and the power to weight ratio is ridiculous!

[@BaconNinjaFPV]

I really need to build up another 4". I have a bunch of every other size, but for some reason I only find myself with one four inch quad on the wall, lol. Also, I do love a good FPV Cycle motor!

I was going to make this one a 4S with a more traditional motor pick, but then I decided.....hey, why not go crazy with this one, lol. Kinda glad I did too, because I have more traditional 3" builds and this is the one I take off the wall every time I want to fly something in this size class.

I have been working on my Mattys. Halfway there. The smaller drone helps me learn how to do a trick. Less to break on a 3.5 aos and frames like it. I'm a Slow learner...

[@1997Jeep]

I just built an AOS 3.5 & I'm right at 250g (throttle caped at 75%) My other go to is a Babyhawk ll (throttle caped at 65% over 10 minutes of mixed flying) I have the throttle cap on a switch as my quads are set up for flying through the trees at my house. In an open field I like to have more top end power but flight time is cut in half & battery packs take more damage.

[@QuandarNl]

Exactly! the aos 3.5 is a little less durable because of the camera mount / bumper. But 3.5 inch with the p1604 motors at 6s is just amaaazing. The siren f3 would be good with the f1404 2900kv motors on 6s, but why not just go 3.5 inch if the weight is the same :) When they create a 3.5 inch with the same weight, I will buy a siren f3.5

[@BrandonBeans]

the gyro_scaled plots on that frame look really easy to work with 👍

[@Atlas_FPV]

The Rekon4 FR with 3.5” props is an exceptional quad and it’s a BNF. It genuinely flies like a 5”. At your weight 270-300g you’d enjoy 3.5” props more, they have a bit more instant pop that I found 3” lacked at that weight.

[@BaconNinjaFPV]

I think 3.5" props would be a good option for sure. I didn't find this particular build to be lacking punch, especially with such large motors and on 6S, but a little larger prop can get it there too. I think we are going to see a whole lot more in this size range over the next year!

[@Catboy-hr2qp]

​@BaconNinjaFPV have you tried a little more aggressive prop like the tmotor 3140s?

[@mcronfpv8736]

i'm tempted to try my flywoo explorer LR4 with 3.5" props... it doesn't fly so good with 4inch

[@_burd]

Regulations aside, the weight saving you get with smaller builds really changes the forces involved in crashes. Ive been learning tricks/cutting grass/pounding walls on a Flywoo Explorer LR4 O3 (on 4s 1500mAh's) and my 5" 6s freestyle friends cant get over how much of a beating it can take. We think its entirely down to the total take-off mass. I still hit the ground at 50mph but because Im significantly lighter, the impact joules are a lot more forgiving. You /do/ need to fly better because you dont have the punch out forgiveeness that 6s will bring you but I guess thats good to learn on. The 15min flight times are a plus too :)

[@efelton2699]

Thought about this frame but ended up with Aos 3.5. Also on 6s with t motor 1604. And the mamba Aio. I’ve blown it to pieces twice. Waiting on new frame. All electronics good thankfully.

[@BaconNinjaFPV]

yeah I have basically just fallen into the camp that if I get 3 mins then it is at least "do able", but it does mean bringing a whole lot more packs. For my particular flight style, flying for much more than 3 minutes at a time almost always results in catastrophic crashes anyway, lol.

[@PaulSokolov]

Great build, and thanks for your tutorials. Could you share PID and filtering screenshots or diff setup for this amazing build. Thanks .

[@LehtusBphree2flyFPV]

My main problem with quadmula frames is where you put your esc there's 2 metal press nuts right below it. I have to get a plastic sticker to put over that to keep from shorting out in a crash. But my 2.5 inch quadmula cap holder is great place for a small cap. Other wise it's a great frame.

[@sixtofive]

Another frame option worth considering for this style of build might be the 2Fiddy with the 4" arms running 3.5" props. I think my 5" 2Fiddy is going to end up getting the new avatar hd pro that just arrived when I get time for building again.

[@BaconNinjaFPV]

the 2Fiddy is a great design, hands down. I think the avatar HD Pro is a perfect fit for it too, especially if you are cool with using the on board 1080p recording. Having that 32G of internal storage has really made me feel better about using it for shareable footage.

Nice 👍🏻 love the build and your thoughts! 248grams dry, nice 😉 that quad would run just fine on a 5 gram ESC, it’s definitely over-built, but that’s not a bad thing!

I’m just on a lightweight, high performance kick recently though 😜 since the Runcam90 AND the ultra performance racing builds, all my stuff is getting faster and lighter 😁 weird how that is, eh 😊 My 6” bi-blade flow-style quad is just a few grams heavier than your 3” ripper 😜

[@BaconNinjaFPV]

it is 10000% overbuilt, lol. I could absolutely come down a bit and probably make it more reasonable, buuuuuuut you know how it goes.

I really like the idea for the build. I would like to do something similar but under 250 grams. I'll probably go analog to save weight and money as all I have are analog goggles for now. I'm fairly new and waiting to switch to digital till I see how the whole remote ID thing plays out and who supports it the best, plus I still crash a lot so I'd rather have to replace an analog vtx than an expensive digital one.

Cool build this is something I wanted to build for a while. My 5” is really loud 😊. How come you didn’t put the capacitor on the xt60?The way how I fly I would have to put a buzzer on mine though lol

[@BaconNinjaFPV]

This one kind of sounds like a whistle unless you are super close to it, and even then it isn't as scary sounding as a bigger quad is. The main lead is actually pretty long on this one since it runs under the frame. There wasn't any room to run it over the O3 unit, and coming out the front was just as tight. I wound up using the Quadmula wire paths that go under the back of the bottom plate and back up the rear standoffs, so it would have been a little long for getting good performance out of a cap on the XT60. It was tough to get it in there, but after plenty of fiddling I got it, lol.

[@SilverFox80521]

Have you tried a 3.5” quad yet? I swear that extra 1/2” makes a huge difference. 3” is so much less efficient. It’s just under the ideal weight to power ratio. You can double the flight time and maintain nearly the exact same flight characteristics with an extra 1/2”.

[@BaconNinjaFPV]

I sure have, and they are great! For this particular build, the power band of the motors along with the thrust to weight ratio and disk loading parameters were just what I happened to be looking for in it. It was never going to be a flight time rig for sure, wayyyyy too much motor and too little prop for that, lol. It was more about the ability to carry the weight in a particular way that let it feel like I wanted in the kind of moves that I do :) 3.5" is a great spot to be though for lots of other things!

[@BaconNinjaFPV]

The ones I am running on this are XT30 and I don't believe I have seen many down that low in mah that have an XT60. I run a little 60 to 30 adapter on the small packs, and as long as the 30 is on the battery side then it shouldn't be rated to ever put out any more amps than what the XT30 can do and remains safe. Doing it the other way around however does mean that the potential amp draw through an XT60 from a pack with one might eventually melt an XT30 at some point, so I do it the first way.

I just finished a tiny whoop build. Thanks bacon! Keep it greasy bro!

[@BaconNinjaFPV]

So the HDZero standard micro sized cameras should mount up in this the exact same as any micro sized analog camera :) The stock plates should fit you just fine either way as long as you aren't using nano cameras for this build, in which case some changing is in order. As for the arm guards, they match the mount spacing exactly and are a pretty darn great design.

[@chrisbee5481]

Did you change to the HQ 3x3x3 because they are better than the 3.1x3x4 props? Have you tried the DALprop 3028? Are the props in view on this one?

[@BaconNinjaFPV]

The props are a tad in view for sure! Having a really small wheel base makes it hard to not have them in view unless you start running more of a deadcat configuration. I do have a much better prop layout one in the works though :) I switched over to the 3x3x3 mostly due to durability on the quad blade props. Every crash would mean having a blade brake off due to the limited joining area as you increase blades. It works out well when you have ducts because they take the impact, but the tri blades do hold up a bit better. I like the Dal, just preferred to stick to the HQ since I liked the flexibility in their blade profile for a little additional smoothness.

[@christhorney]

im honestly suprised that your able to go from hdz90 to djio3 and still be ok, i went from a caddx ant to a ratel 2, its about a similar difference in latency, and i honestly felt so disconnected, i had to go back to an ant, and i put the ratel2 on my plane, and its fine on the plane just trying to dive gaps or fly close to the ground or things, and you are doing your crazy mind bending freestyle with an o3 after using hdz90 its crazy, i wonder how much or if at all you personally notice the latency difference?

[@BaconNinjaFPV]

I do notice the latency difference, and the smoothness difference for sure. I have just found that I am pretty naturally inclined to adjust well after a couple packs of each and get back in the zone. It usually starts out by flying a little higher than I normally would after I switch over, but by the end of pack one I am right back close to the ground where I want to be. Now that isn't to say I don't crash more on one than the other, because I totally do :p

Would really love to build 3.5" freestyle quad. I have geprc speedx2 2105.5 3450kv motor will it be suitable for 3.5" freestyle?

[@johndeesfpv9289]

did you do any motor limits ?

[@BaconNinjaFPV]

No I am just going full capacity when I run this one on 6S :)

[@fpvblacc]

When you orders this frame did you grab the 9mm or 12mm arm Guards for the 3000kv motors , would you be able to use either one ?

[@BaconNinjaFPV]

That one is really going to depend on the motors you plan on running. in my case my motors had a 12mm mounting pattern so I went that direction with them. The arms on this frame are slotted to go between 9mm and 12mm, but the TPU prints are a set size so you will just need to order whichever ones will work with the mount plates on the motors you want to run :)

@@BaconNinjaFPV thanks man helped out alot !!

[@cpascariello]

Great video man! I'm looking around to some motors and besides the Emax Eco II that you are using I found the Mamba Toka 2004 / 2900kv. They have exactly the same specs, only that the Mamba is for a 4S. Any idea why? Couldn't I use it on a 6S as well, as it has the same specs?

[@BaconNinjaFPV]

Those Toka motors are a great alternative choice for the EcoII's I am running on this one! They are technically 4S rated for 3.5-4" props, but on 3" they are in the top end of the useable zone :)

​@@BaconNinjaFPV Oh nice man! Ordering as we speak, and thanks for the super quick turnaround! ;)

What sort of flight time do you get with this beast on a 550

[@BaconNinjaFPV]

So usually, with my flippies and floppies, I get right at 3 minutes. If I am just cruising or doing some light loopy stuff I can push that up another 30 to 60 seconds though. It will also haul a 1300mah pack around if you want it to for a pretty insane cruising flight time :)

[@taylorowen7558]

I'm building this f3 split. Did you plug the 03 unit in or solder it to the board? I want to make sure the 03 gets enough power..

[@BaconNinjaFPV]

I did use the plug on mine and it works great! :) Double check the pinout though because if I remember correctly it is exactly reversed on the plug they have in their FC. You may have to pull all of the pins out and re-pin it to line up correctly without shorting your air unit.

[@VincentFlores-ph7ml]

Are you running a throttle limit to run 6son those motors? Im relatively new but planning a similar build and I thought 3000kv it to high on 6s.

[@BaconNinjaFPV]

No throttle limit on this one :) As the props get smaller, KV tends to go up quite a bit in the safe zones. Since the prop travels a shorter distance per revolution on smaller props we usually have to spin them faster as they get smaller. 3000kv on this is right at the top end of 6S use on 3", but for sure in the safe area. On 5" we usually don't go too far above 2000kv since they have a much longer tip travel path.

[@adrenalinelife945]

Did you have to re-pin the DJI O3 jst connector to the FC…or did it match as is?

[@BaconNinjaFPV]

on this one I did have to re pin. I believe it was exactly backwards from the stock pinout, so I took them all out and put them all back in the opposite order. If you plan on doing it just double check first, but I am pretty sure it was just a completely backwards pinout for that connector.

verry nice bro! but if you want to go the old analog path..... what vtx would be best?

is this guy flyable on 4s with this setup ?

[@fpvblacc]

what are your thoughts on the 650 and the 850 6s GMO lipos batteries going on this setup ?

[@BaconNinjaFPV]

they are for sure a little heavier, but it will still fly with them. I flew this one with a 1300mah pack and it still stayed in the air, so it can handle the weight. You may get a little worse flight performance with a heavier pack though, but if you are more interested in flight time than really tight flippy flops it should be fine.

I got back into flying again , I have a mark5 hd same one as you threw away, and a babyhawk, which i rarely use. i also have a mark5 hd extra fc and esc. what would you recommend i build? i would prefer to stick to 6s (since my mark 5 ) could i use components from the babyhawk ? such as the vista ? build a 3" 6s or 5"?

[@BaconNinjaFPV]

Hmmmm, that is a whole lot of decisions! You could absolutely use the Vista out of the babyhawk on just about any frame. As for using the FC and ESC that you have spare, that would probably be best in a 5" since they are sized for a Mark5HD. On a frame for that one there are a tooooon of options. I would recommend the Quadmula Siren F5 Split because it has been so great to fly over the past few months, but there are a ton of other choices as well depending on your budget.

[@ITrott]

question how are u using an xt60 connector on esc but running an xt30 battery?

[@BaconNinjaFPV]

I just run a little 30 to 60 adapter :) since the small side is on the battery, it won't ever be able to provide more than what the 30 is rated for so running a 60 up stream is safe. Doing it the other way around though where you have a 60 on the battery and a 30 on the quad is a great way to melt some plugs.

This size for freestyle really interests me. I picked up a speedybee flex25 for cheap and I'm thinking of converting it to a 3inch like this on 4s. What do yall think?

[@BaconNinjaFPV]

hmmmmmm, if you can get the props in there since it is a whooped pusher, then I suppose that would work! I do think though that you may hit a limit on the prop overlap between the front and rear motors if you go any bigger than the 2.5", but there is only one way to find out, lol.

[@dustinwilson492]

@@BaconNinjaFPV I guess I wasn't very clear with my first comment I want to pick a new frame to swap the flex25 components onto. Something without the overlapping layout. I don't have the funds for a build but I got the flex so cheap my first thought was to use the parts on a new frame.

[@BaconNinjaFPV]

@@dustinwilson492 ohhhhh, I see, that makes a whole lot more sense to me now. I am actually looking at a few frames this month that would be great for that at reasonable prices. Those bigger motors are going to need something kind of stuff, so toothpick or thin frames would be hard to keep resonance minimal on. GEPRC makes a smart 25 frame that would be a good option, and I have one on the bench from Unger CNC that is looking really promising for 2"-3" builds. I would say this Quadmula frame could do it too, but you may be into needing something different ESC wise due to the extra weight of it.

[@dustinwilson492]

@@BaconNinjaFPV ok so I need a light conventional freestyle frame. I was wondering about the 35 amp esc. I don't need a beast just looking to move up from my baby ape. The flex seems really strong on lower rpm but nothing at the top of the range. I was wondering how much of that was prop or loss of thrust from the cramped layout.

[@FPVQatar]

Do you use bluejay for the esc? Because my motors run steaming hot after I fly, exactly like your build and tune, but I get 2 minutes only in the battery before it reaches 21v

[@BaconNinjaFPV]

I sure do! I have heard lately from quite a few people that the most recent version of bluejay is doing this on some quads. I have not personally had it happen to me, but it may be worth flashing back one version to see if that gets better. If it doesn't then you may have some source of resonance getting fed back into the gyro and expressed in d-term causing those hot motors. There are some things that can be done for that though, so lemme know if rolling back one version doesn't get it!

Hello Bacon, i got one question for you. I love your build with your 3inch.. I have décided to follow the same philosophy. i built a similar one with à micro apex 4 frame. I got F2203.5 2850kv with speedybee f7 mini. I cannot fly it in 6s without puting à motor output limit at 60%... If not i got a death roll... 😢😢 Do u know what ?

[@BaconNinjaFPV]

The death roll is absolutely easier to find on this size build with bigger motors. What PWM frequency are you running, and are you doing bluejay or BLHeliS? I have found that lower PWM frequencies and some adjustments to the ESC like higher demag compensation and lower timing will really help with the rolls. I have had this one do it one time, but that was the only time it tried to.

Hey I copy your build it flys nice and smooth but motor are burning hot. And im having the desink problem. I know in the build descrition you mention “You may find that you want to run your ESC with demag compensation set to high and make adjustments to timing or ramp up power to avoid desyncs” I set mine to power set to 60%. Demag set to super high,timing at 26 still motors super hot any guideline will be appreciated

[@BaconNinjaFPV]

hmmmm, if you have tried those things but are still getting really hot motors there is a good chance that your build has a little more gyro feedback than what is ideal. Some things I would try for that though. First, make sure your stack screw nuts aren't too tight. If you are compressing the gummies too much then they wont properly isolate the FC and it will need way more filtering than normal. Next I would make sure you don't have any wires flopping near the gyro since that will act the same way. Last, make sure your m2 bolts going through the bottom plate are tight and seated all of the way. If that little puzzle piece doesn't sit properly it will cause some serious gyro noise issues. If all of that checks out, go to the PID tab in Betaflight and move your filter sliders a couple of notches to the left to see if that helps. If that does help, it is for sure a gyro noise issue.

3000kv is about 8% higher than the average for 3" motors on heavier rigs, so not too much higher than you might typically see. I wanted this one to be able to carry a little more weight when it needed to, so that overage helps to accomplish it a bit :)
