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.

It is worth when placed for small frame ... just need to use thin heatsink on main chip and fan when stationery ... Nice one

@Mangorille

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.

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

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.

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

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 did with the Vista on a whoop and 3d printing some stand off (kzread.info/dash/bejne/l2FhtbuOg8iXgto.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.

@@Mangorille on the vista, i use an rc fuel silicone tubing.. cut to length. Its quit snug when you tighten it.

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

What is the point to shave off a few grams and make it more vulnerable to damage

@Mangorille

Жыл бұрын

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.

light weight ASA works best

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

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).
