      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.

    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

    • @Mangorille
      @Mangorille  10 месяцев назад +1

      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.

    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.

      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.
