Almost PERFECT DJI O3 SUB 250 Gram Micro 🤯 | The NEW Quadmula Djinn F25 2.5" is Here!

- čas přidán 22. 05. 2024
- Quadmula continues to deliver impressive design and quality with their first new frame of the 2024 model year. The Djinn F25 is an amazingly fun, capable, and smooth 2.5" that looks to balance freestyle and cinematic flight. Specifically designed for the DJI O3 system, the new Djinn F25 has no props or frame in view (even in ultra wide!) while maintaining a fully symmetrical arm design that doesn't have you digging through different size arms in the event of a crash.
For transparency, the frame and props were provided by Quadmula for this review. All other parts were purchased by myself. Quadmula has not seen or reviewed this video prior to its publishing.
Make sure to check out the links below to the parts I used, my 3D STL files, and my Betaflight setup.

This is the only video on the whole youtube which provides clear details about the build on this quad. Thank you!
Thanks buddy. Happy flying!
Super detailed videos. Thanks for that. I tested your tune and am thrilled. My quad flies very well for cinematic videos.
Thanks! Happy flying!
Excellent video, thank you very much!!
Welcome. Happy flying!
Good work ! Experimenting with 3 inch builds myself - Super nimble & quiet - What's not to like !
Thanks! I’ve been focused on this size since 2019, quiet, fun, and really easy to abide by the local regulations.
Great video and thanks for sharing your tune, just built my own Djinn25 in a very similar config and while stock betaflight was alright, its definitely much smoother on your tune.
Glad to hear that. You can also go through the PID Toolbox process yourself to find a tune that is more specific to your own quad. czcams.com/video/dnVW6agh_u4/video.html
Hi just finished the build , your tune says force-4-cell batery ,
Do you have a tune for 6s?
I get a lot of prop wash with your tune for some reason - thanks just finished building it and loving it 🎉
@@orangure I only flew this setup on a 4s battery so you'll need to do a tune yourself. What 6s battery are you using? I like to use PIDToolBox for the PID tuning: czcams.com/video/dnVW6agh_u4/video.html
Hi, wich BF Version do you flight for your djinn? Regards Sascha
Wow I really love the quadmula Frame and your building video. Yesterday I got the DJINN 25 Frame and really exited to build it up.
Which rates and pittuning do you use? Thanks so much and keep Flying und Building!
Hey. Check out the video description for a Betaflight dump file with my configuration. You can see the rates and PID tune there.
Building two now the 3.5 and 2.5. I fly my Quadmula Siren F-5 it's my daily it flies amazing and it's Indestructible, I hope the small ones are.Also i'm sure they will be they're smaller and lighter.
The 3 inch is my go to. They fly so well that I very rarely fly the 5 inch now a days. I’m going to be doing a Quadmula 3.5 build soon.
Love your sub250 build videos! Does your o3 air unit get hot or ever shut off when making it naked with your stl files? Or how does it do with the heat in your experience?
Thanks! It does shutdown after a couple of minutes on the ground but never in the air. Check out these two videos:

@mangorille: Hi, I'm a fan of small copters and I fly a 3 inch and a 1.6 inch copter with the Vista unit. I think your video tutorial on the djinn 25 is great! It's also great that you share your setup with the community. What do you personally recommend, a 4s setup or a 6s setup for the 2.5 inch? Greetings from Germany
Hello. How important is it to stay under 250grams for you?
hi! i run your PID tunes you show in the video...seems to be good, but i am still struggling with rates. i use 2.5x1.5x3 HQ props that results in low propwash buuuuut you always need to push a little bit more on the throttles to get the copter up in the air. i am still not familiar to it. BTW: the weight of my copter is too high...251g with a little bit more of battery wiring and even 257 when i am going to built in ELRS. THX4 the video!
Hey. I’d suggest going with a higher pitch prop especially when you’re running 3 bladed props on such a heavy quad. Any way you can go lighter on the quad as well?
Been flying my Djinn now for a few days now in many different configurations and I think Quadmula should consider selling longer arms to convert it to a 3". I've tried all the suggested props and it stills feels a bit too heavy in the power to weight ratio. My configuration. Speedy mini stack, mamba 1404 3000kv, dji 03 with all printed TPU. The tune is pretty bad too. Mangorille....love your content on FPV and 3D printing. You really know how to present material. Thank you.
Thanks! What battery are you using? Mine was 240g ready to go, which is on the heavy end for the 2.5 inch props. I can get it down about 14 grams to 226 using the lightened o3, which is really where you’d want it. Don’t tell Quadmula but I tried to put my 3” arms on this frame and they didn’t fit. The second arm hole was off about a mm.
@Mangorille using some Liperior 6S 650's which bring the total weight to around 275grams. I ordered some 550's that weight about 73 grams which should bring me to around 250grams. Do you think with a little modification the F3 arms would work?
Please try the presets"4.3 Filter settings for VERY CLEAN build with RPM FILTERING". This is the basic setting for Djinn F25.
After changing the settings, please observe whether the motor temperature is normal first.
@@victorlugardo3703 Hmm, that is on the heavy side for such a small quad. I personally wouldn't try modifying the arms, it will cause play and make them weaker if you elongate the hole. I did some math, even with the 550s, you are still going to be at 248g. Better but anywhere else you can find to cut another ~10grams?
That's the only reason I'm going for the AOS 3 inch. 50g frame weight and designed for the 03
Not ragging on quadmula but the 2.5 size is a bit limited
awesome video! if you had to pick one, would you prefer the quadmula 3 or 2.5 ? I'm on the fence and i cant decide!
Why type of flying do you plan to do and where?
Also. I just subed great video bro.
Thanks buddy. Welcome to the channel.
Murders fpv channel uses a 650 6s battery for the large straps. I wish @quadmula would include 4s battery straps along with 6s straps
Actually, even though it's a 20mm wide strap, it's shorter in length and specifically designed for smaller batteries. It's currently also being used on the SF3.
He must be over 250g then, I'm at 240 with a 4s so I would estimate that he's at minimally 265g, which defeats my goal of this build but yes should allow him to use that strap. :)
@@vts5520i Yes the F25 comes with the same strap as the F3, both of which are too large for a 4s 650mah battery. I've tried cutting it shorter but then you're not left with enough of the velcro material to secure it well.
@@Mangorille You're right, that's actually true!
@@MangorilleI'm running 6S motors with 380mah 6s GnB 's and weighing in at 244gr ... Thing flys great with my thorough pid and filter tune. I tried tattu 650's 6S, but it was too heavy @299 grams and just didn't feel that good flying.
How did you fix reciever to top of air unit? Great build!
Thanks! I use some strong double sided tape (the 3m outdoor stuff from Home Depot).
I‘m more the Freestyle Guy😎 luv my 5 inch. My 3 inch is nice to fly, but the QUADMULA Frame rocks and i like to try this 2,5 inch Ripper with my hd Setup. I saw a lot of Videos with the 6s . So how is the Performance ? What do you recommend? On my 3 inch i use 1404 4800KV Motors and the Copter has a lot of power with 4s.
If under 250g is not a priority, go with 1604 motors and 6s. The reason I ask about 250g is that most small 6s battery packs (say under 600mah) start to lack in performance (e.g. high internal resistance).
You need a discus. Lol i need to redesign a O3 version but it will easily surpass ur needs. Dogcom 550 have new tech and weigh like 20g lighter than 650s so that probly be a fun option and triblades but how you liking those 4 blades? I have em but so behind on testing.
I was surprised that the 4 blade flew better. First time running 4 blade for me.
Hi, i saw the filter Setting in den BF Tab, Both solidere are full at the right side. Ist this correct? Whats the motor temperature, are they overheating? Regards, Sascha
Correct, I rely more on the rpm filter. You can have the sliders all the way to the right if your quad is mechanically sound and not very noisy. If unsure, start with the filters in the middle default position.
What is the correct way to trim antenna tube, do you cut the wire and slide it out? Or you get a pair of scissors and trim it carefully?
I used an X-Acto knife to carefully slice the tube along the circumference. Once it is two pieces you can use scissor to slice it vertically and route the wire out. The UFL connector at the end isn't very strong so don't try to pull it though, the wire will separate from the connector.
i might try to use 1604 motors on 4s with 6-8 blade props.. just for the noise.. how do u think it would fly?
I thought about 1604 motors but those are really for 3.5 - 4 inch quads. Seems like too much motor for such a small quad. You can probably run the 6 blade props on the 1404.
What kind of material and filling degree do you need to print O3 tpu side panels to ensure that there is no jelly?
The camera side plates? TPU at 20% infill with 0.15 layers.
Hi Mangorille do you use Bluejay or the Stock esc Firmware Bl Heli S, with your PID and Filter Setup ? Oh sorry i didn t see your Video Part with the Bluejay flashing my mistake
You want a firmware that has bi-directional dshot. Either blheli32 if supported or bluejay.
@@Mangorille i have the Same Stack with the new Bosch Gyro . ESC are jh40. Bluejay is possible
@@SaschaMittag Definitely get bluejay on there.
Hey bud I didn't see that remixed part posted anywhere in the description ❤

I'm on the fence if I should build the 3 or the 2.5 from quadmula. Which one do you like better? I've wanted to use it for freestyle and some cinematic flying in the city/a more crowded area. Because of the new laws in Europe it's not allowed to fly over 250g self built quads closer than 150m to building and people anymore. And is the EP2 sufficient range wise? Even with an EP1 it should be under 250g right?
Which is more important for you: freestyle or cinematic flying?
@@Mangorille probably freestyle
@@timspilka4684I'd suggest the 3" in that case. The only negative with the 3" is that you have the props in the video recording but if that's not a deal breaker then the 3" is the better freestyler.
Hey Mangorille, I'm new to drones in general and especially to drone building. Always flew prebuilt ones so far. But I got more and more interested in them and your video gave me the extra push I needed to jump into it. I love that setup, and trying to reproduce it as much as I can (i.e couldn't find your iFlight XING2 1404 4600kv Motors in stock, so I ended up switching for BrotherHobby TC 1404 4600KV Motor, though I don't even know what's the difference). A quick question though, is there anywhere I can find what extra wires I will need and / or a plan on how to soulder all that together? xD
Hey. Very rewarding to build your own quad, congrats on taking the first step to doing so! If you choose the SpeedyBee ESC/Flight Controller Stack I linked in the video description, it comes with an amazing manual to walk you through where you need to solder up the wires. All wires are included with the parts you will purchase. The only thing would be the receiver that may not come with wires. Which receiver are you looking at?
@@Mangorille Haha yes, and thank you for your kind response, I'm eagerly waiting for that feeling of proudness for having built my own. Good news that it comes with everything and instructions. I'm not sure yet, because I have the googles 2 and the DJI controller 2, I was maybe thinking about going with just the O3 for now, I know there's ELRS and crossfire, and I've heard a lot of good things about ELRS and the Tango controller, as it has more penetration and range than the DJI O3 built in receiver, but I didbn't make up my mind yet. Any advice on that one?
@@Mangorille But yeah, your videos are inspiring, keep up the good work and vibes
@@malinaanaho If you already have the DJI FPV Controller 2, use that for the time being. I went with ELRS and the Tango 2 for more reliability and the full size gimbals. You can always add that later on.
@@Mangorille Hey again Mangorille, one last question, you mention that your ESC is the other way around, does that not pose any issues about the way you connect the motors then? Or does it not matter which one connects to which?
I have a speedybee f7 mini as well but I cant find a pinout for the o3 air unit. How did you connect them?
Check out this picture from the F7 Mini manual. The O3 will wire up the same as the Vista in this picture except that the O3 has one black and one brown wire instead of two blacks on the Vista.

i do have a f722 mini 4th version, it doesn't support bluejay :(. thanks for sharing this nice video...
Welcome. Happy flying!
I have the problem that I bought a ready-made Djinn25, which has the same hardware setup as yours. Unfortunately, I can't set up the copter properly. It twitches on the yaw axis during flight. I want to test your PID tune now. I suspect a defective gyro.
How exactly does it twitch and under what sort of maneuvers?
@@Mangorille i have these twitches, if i take off and the Copter does go with the back to the left side clockwise. During flight, you can also clearly see these twitches through your glasses. I suspect I have a bad gyro. I will now test your dump and see if the flight behavior changes. Without a propeller, the motor tab looks inconspicuous. The motors spin up smoothly without any failures. Really weird
@@SaschaMittag Without the props on, do you feel any weird vibrations when you spin up the motors? If you put all the bars at one point on the motors tab, do all the motors show roughly the same rpm (you'll need bi-directional dshot turned on for this)?
@@Mangorille no weird vibrations, i changed to Bluejay and Set the Pids and Filters to default. The copter Flow better. I will try your Set up again and give you a reply.
How did your weight end up at 235g? I've just built mine and I'm on 251g with that same battery. My stack is the other way around but that's only going to account for about 3grm of wiring, where you have an extra zip tie.
I can't see where I'm wasting 15g
That's with 3 blade props too.
Check 3:35 in the video where I weigh individual components to see where yours is different. I suspect you’ve got heavier motors. I ended up at 239g with the battery strap after the build.
@Mangorille I don't think it's the motors. Yours work out 41g total and mine are 8.8g each.
All that's different are the tpu feet and chin bumper I have. Plus a rubber band on the battery to keep the balance lead out of harms way.
Could it be the 8 prop screws? I don't see those on yours when your weighed it.
Or my scales are wrong, I prefer that option 😂
@@davidcane7211 The TPU feet and chin guard are 6 grams, which I don't run. The final weigh in did not include the prop screws so that would probably add another 2-3 grams. You're not too far off my build. The rest can be simple things like wire routing, type of wire in your power lead, etc.
@@Mangorille I changed the battery strap for a shorter narrower Diatone one and seem to be down to 250g with the 4 blade props. Also changed the rubber band on the battery (strapping the balance lead down) for a shorter one.
Quite happy now, just need to conformal coat that stack so I can crash in the damp british grass 😀
@@davidcane7211 Great! If you really want to reduce the weight, go with a decased air unit. I've done that and have another video on my channel.
any of you guys know a place to buy a prebuilt drone just like this with this frame kit ???
Easiest is to find someone local who can build for you or check fpvexchange for a build service.
🤔I don't understand why Quadmula doesn't give you reviewers a purchase link with a small discount for your followers, to reward both you who present their products to the large public and in the meantime you youtubers give a small discount to your followers who help to grow your views and therefore the channel, their frames with some accessories cost a little, but the shipping cost is really exaggerated, okay they'll give you 1 more arm for free🤣 BUT MY QUESTION IS: QUADMULA Djinn F25 Split top and bottom plate, will almost certainly be able to accommodate the arms of the 3 inch QUADMULA Siren F3 Split, you who have the 2 frames have surely already tried to interchange, but let's not tell this to future Quadmula customers😉 Thank you for sharing your experience with us so that we can learn from you🤗😊
I personally haven’t had any company provide a discount link. I know it happens but I haven’t seen it myself in the FPV space. Funny you say this because I did wonder if I could swap the arms, the arms themselves look the same other than the f3 arms being longer but the geometry of the frame is different so I don’t know if you’d still not have props in view with the longer arms of the f3.
@@Mangorille sir, if you can try to exchange them, I would be very happy to know your experience, because I also saw your video on the Quadmula Siren F3 Split ... I repeat, I'm sorry if Quadmula really doesn't recognize your work, we'll see in a few minutes of videos, but behind a video there are precious minutes of the life of a person who has decided to share his experience, presenting a company, you are good man and thanks for answering me, thanks again☺
@@kris-kb4vf Quadmula has been a great company to work with... I actually tried to swap the arms, although they look identical (except the 3" being longer of course), they are not interchangeable. The arm holes are off ever so slightly.
@@Mangorille thank you so much for trying and writing me a reply, you are an exceptional person, thank you very kindly☺
Hi Mangorille, please can you make a screenshot from your Pids and Filter Settings from your 4s Setup. I would like to Test this with my Djinn Build too. I use BF 4.5.0 default Settings and like to Test your Pids and Filters. Thank You for your Support , best regards Sascha
The pids you see in the video is on a 4s setup. You can also find the betaflight configuration file in the video description.
Is there really not a camera mount setup available for the f3 that has no top plate in view?
The f3 only has a tiny bit of the top deck in view in the goggle view. The onboard view doesn’t pick up the top deck (at least at normal with 26 degree uptilt). No way to get rid of the props in view though on the f3.
@@Mangorille I'm ok with the props in view but the top plate in view seems insane, good that it's not in the goggle view but it'll drive me insane to lose FOV cropping in on the DVR footage....dam
@@CiottiFPV On the F3 it's the other way around, no top deck in view on the air unit recording but a tiny bit on the goggle view. Check out 1:48 to 1:58 in this video: czcams.com/video/gxt-7bHG9vQ/video.html
@@Mangorille oh HELL yeah, that's what I want to hear, ordering one right now lol
Lol sounds good. You going with a sub 250 build? Here is my f3 build video. czcams.com/video/IKHoPryhvCg/video.htmlsi=I7Z7Ku10kCVqi_YW
I'd love a Quadmula but sadly they don't ship to my area..
I thought they shipped worldwide. Where you located?
@@Mangorille I'm in South East Asia. Emailed them earlier in the year and Quadmula replied that they are looking to distribute to Asia this year. But as for now, can't order any yet.
@@velocistafpv Ah okay, perhaps email them again for an uodate. I see a note on their site saying "Worldwide shipping".
Why Bluejay/Bidirectional DShot?
You need bi-directional dshot in order to use RPM filtering, pretty much the standard way of filtering now-a-days. This is not supported on regular BLS firmware so you need to install Bluejay. If your ESC is a BLHeli32 then it already supports bi-directional dshot and you wouldn't be putting Bluejay on it.
Awesome@@Mangorille thanks!
