that new flywoo o3 naked kit is very similar to this. i switched to using 2 diy linear antennas which cut a lot of weight as i no longer need a big tpu mount.
The RF shielded areas aren't fully sealed to begin with and there are areas of the unit not covered by the RF shields. But yes, making it naked could impact the durability given that the components are more exposed. I haven't had any issues yet and I crash all the time in wet grass.
I did with the Vista on a whoop and 3d printing some stand off (ruclips.net/video/e--SYUSe1Rw/видео.html) The problem with that approach is that: 1 - You need to make sure that nothing touches the two halves, including the tops of the ribbon cable connector. 2 - You don't have anything holding down the board ribbon cables, the antenna connectors, and camera cable. They can pop off in a crash. It will work okay for a whoop but anything bigger and you'd want some sort of strapping to hold those connectors in place.
hey, i have the o3 ultra and cant get it connected via usb , i have signal in the goggles but cant access the footage from the internal storage, you know what can i do ?
@@Mangorille inside the port ? or the connector? and yeah I use MacBook and all the other o3 drones I have are connecting fine with the computer and those cables
mangorille! thank you for this! nobody else has done such a comprehensive naked guide yet. quick question for you. Would you be willing to give the caliper dimensions of your naked 03? I'm wondering how tall it is to fit into a slammed build. Thanks!!
Hey All. For those of you suggesting other 3d print materials to save weight, I found a site that provided the densities of the various materials. It looks like ABS would save bit of weight. ABS 1.04g/cm3 ASA 1.05g/cm3 TPU 1.21g/cm3 PLA 1.24g/cm3 PETG 1.27g/cm3
DId You consider to add micro fan .... just when You started it it won't instantly go hot .. well now You need to use external fan when stationery ... as when You will fly it will be cool
I'd be too worried about the overheating the electronics, that might cause damage over time. Especially when I use a GPS, and I have to wait idle before takeoff, anywhere from 10-30 seconds for satelites to sync. The only way I would consider doing this, is if it was a winters day OR I had one of those portable jet fans blasting air at it while at idle I'd rather look for weight savings with a lighter frame, motors, props... titanium screws and standoffs, and smaller batteries. I even saved a few grams ditching the battery strap, and going for an industrial elastic band and adding strips of double-sided silicone tape on the battery pack for extra grip
Understandable, I only run this on small lightweight builds, which would be those builds without a GPS. If you are adding a GPS or an action cam, then no point to chase a 14gram weight saving by doing this.
@@Mangorille Still found the process interesting though. If there was a way to incorporate heat dissipation for the o3 into the frame without compromising rigidity of a light frame, that would be an amazing feat
@@rubberonasphalt I've seen some frames do that but it usually ends up adding weight. You can always just remove the case and keep the RF shields, that gives you more heat dissipation.
Wish someone could decase the moonlight.. But i wanted Mad tech take it apart and the middle of the case has sdcard and connectors. so youd have to cut that out and keep it some how
This is great, man! You covered everything completely but concisely and didn't leave any questions unanswered - for me, at least. Not sure if I'll end up doing this, as I'm new to the 03, but I've done plenty of naked vistas, and have been wondering if that would work with an 03 AU. Initially, I only planned on getting 2 or 3 of the 03 AU but you know how that goes lol.
I understand that! I just ordered my 5th o3 after going back to the Vista on my last build. Even with the Nebula Pro camera, going back to the older system after the O3 is pretty tough. Now I only use the Vista with a RunCam Phoenix starlight camera for night flying! Maybe soon we can get a good low light camera for the O3 system. That would be great!
i had to do this last week to get weight down under 250. i was pretty confident that the material i used was petg but after assembly it turned into chewing gum as it turns out i used pla and this thing gets hot even with a fan blowing on it. printed it again in abs. works fine for me so far. lets see how it handles summer heat. for mounting i used soft double sided tape and a zip tie.
PETG would work, definitely don't use PLA as it would go soft exposed to that heat. I went with TPU so that it has a bit of a inherent soft mounting in crashes.
You mean completely waterproof or just water resistant? You can use conformal coating but I haven't had experience with this making things waterproof (i.e. full submersion in water)
Adding a fan on the bench would be good enough. The beauty of the O3 is that you don't need to power it up for firmware updates or to pull footage from the onboard storage (like you had to with the Vista) so less chance of bench overheating.
O3 gets hot as hell stock! You remove here all heatsinks and thermal compound for the sake of “saving” few grams. These small quad mostly don’t have gps due to crap f411 fc’s with not enough uarts - if your vision will fail say bye bye to your drone... Too risky imho
Agree that they overheat quick on the bench, but they actually don't get that hot when in flight. You can find good f7 mini flight controller now-a-days. I've got f7 in all my quads, even the 3" sub 250 gram ones.
I loved the old black DJI controller and used that for 4 years. Not a fan of the new gray one and it had some serious signal flaws when the o3 released, even failsafed on me 2 meters away (I hear it behaves better now though thanks to firmware updates). I did try it and even made a video on it (ruclips.net/video/QRpH3c9G-Y4/видео.html)
@@Mangorille it was O3 FW fault.. I have broke my first O3 build on first flight because of RX drop but it's fixed now. And I put longer gimbals, it feels like the old DJI now. Only two 3 positions switches were annoying.. but again moved arming and beeper on the same switch, problem solved. It does everything my BetaFPV pro radio does just without the need of RX. :)
Love this video! Great video! I appreciate the testing. I wonder what the temps would be without the TPU mounts. I wonder how ICE9 TPU would do which is better for conducting heat.
Depends on your use case, for a 5 inch+ I agree with you but with smaller builds, 13 grams can be 5-10% of the total weight of the quad. Plus some folks try to be under the 250gram legal restrictions for extra freedom.
Great work! Only my 5” is using an O3 but I might go this route I install an O3 on my 3”. Overall, I’m not too impressed with the O3 and I think I even prefer the Vista over the O3 as the Mbit drops quicker with my O3. Even tried swapping the stock O3 antenna for a pair of TrueRC LHCP antennas to match my Goggles V2 but that didn’t help much.
I've noticed that the O3 never holds 50mbps like the Vista did back in the day, the mbps likes to move around a bit anywhere between 46 and 50 even with full signal and not too far out. Not sure why this is but I suspect it does this when the processor can't process fast enough. Check this out: ruclips.net/video/WFZL-IyQUmQ/видео.html
@@turionb1408 Hey. I don't believe anyone said the Vista is better overall. The O3 is really good. Where it lacks though is the size, weight, and terrible dynamic range so you don't have as good as an experience when you transition from light to dark places. I know they did a bit of firmware magic a while back to make this behaviour better but still not as good in the dynamic range department as the Vista.
@@Mangorille ah okey i see. Yeah thats true. The reason why i have vistas and 03s 😉 vista with polar cam is a huge difference to the 03. Low light is not the best sadly
The casing of the O3 is already paper thin, this really feels unnecessary. Just using a shorter mipi cable or rehousing the camera with a lighter weight lense feels more practical to shave weight. But really just use a lighter weight lipo like a hv pack.
Depends on your build. For a larger and heavier build, I’d agree with you. On a small sub 250 gram build, this 13 gram saving is about 10 percent of the quad’s weight (without battery).
Looks like you could save a small bit of weight. I found a site that compared the densities of the various filaments: ABS 1.04g/cm3 ASA 1.05g/cm3 TPU 1.21g/cm3 PLA 1.24g/cm3 PETG 1.27g/cm3
It sure over heated much quicker. Seems each step halves the amount of time before over heating! Not quite sure about all of this, especially the last step.
For sure it did on the bench, in the air no problems even with back to back flight including a long ~8.5 minute flight. I wouldn't do this on a 5 inch+ but with smaller quads, this should help make up for the weight of the o3 vs. the Vista.
That's so dumb, stripping down such a well-engineered piece of kit that defines FPV in the first instance. Remove the air unit, and your quad is no longer an FPV drone. You need to be more creative than simply pulling apart stuff with a screwdriver, (which isn't creative anyway, it's more destructive)!!! what about not adding a gopro, or go 4S rather than 6S, you will save more the 13 grams.
This is more suited for those trying to build super light builds, such as sub 250 gram quads due to government regulations. I agree, not worth it otherwise. 13 grams on a 650g 5" is nothing but 13 grams on a 220g 3" is quite a bit.
I am not sure if you are trolling or not... what defines FPV is this exact thing the OP did. Tinkering with drones and building them and modifying them is what this hobby is all about. If anything this guy is what makes this hobby amazing!!!! Keep up the great work @mangorille!

Did you notice any change in signal strength / range?
thank you so much for the instructions, but if you remove the rf shields wont a single drop of water compleatly destroy it?

have you tried using only standoffs instead of those tpu prints? i think it would give more airflow as well as save a couple more grams
Yup there is a 2mm alum spacers and can act as additional heatsink
@@verdi6092 Or, 3D print the stand offs to the exact size you need.

Check the USB port to make sure there isn’t any garage stuck in there. Are you sure the computer you’re using and the cable are okay?

My test shows that you have about 3 minutes before it overheats and after turning it on, I'm usually airborne in less than 30 seconds.
great review! another question, can you share link to the STL for the O3 camera mount plz
Thanks! Which camera mount are you referring to?
@@Mangorille as i wrote - the O3 Camera mount
for printing with TPU do I need an enclosure for my printer? I have the same Prusa i3 MK3S+, also what are your print settings? thanks! Great video
Thanks! No enclosure needed. I put the 3mf file in the video description if you want to give my settings a try. I used Sainsmart TPU.

Any concern about the O3 heating up and melting the PLA?
I used TPU for the print, no issue with it melting (at least yet) even when I did the bench overheating test.
pla won't do. petg or abs . i tried with pla and it turned soft after 5 min even with a fan blowing on it.
Tamiya sells 2mm spacers various size. Can act as a heatsink

At this point I'd use a resin printer.
I don’t think a lot of FPV pilots have resin printers.
