Thanks, very informative. Btw, I'm running 3 of my 4 Vista units without heat sinks without any issues. You just need to have some air flow, i.e. some wind or the props spinning. Without air flow, the goggles display the "air unit overheating" message after around 30-60 seconds depending on ambient temperature. If you still do nothing it shuts of the Vista.. I normally try to avoid that. With the stock unit the same thing happens but it takes several minutes. I have not yet lost any of my Vista units and I'm using them like that since the beginning of the year. Just my experience, I believe that, depending on the rig (especially for Micro's) it's worth the risk to save the weight (I think roughly 15g)
I also always suspected DJI manufactures these, but now that they announced Caddx will be manufacturing Air Units I am not so sure anymore. If it uses the exact same components and runs the same firmware, possible that it’s sold under same fcc id, would be interesting to hear from someone more familiar on the matter. I’ve been running several Vistas with no heatsinks at all and haven’t tun into any issues. Even left one plugged in for like 45min accidentally and it was fine once it cooled down. The heatsink you removed last seems to be the most important one as P1 emits a lot of heat even in low power mode. Even with basic airflow from 40mm props on a stationary whoop it’s enough not to overheat unless it’s sitting in the sun on a hot summer day. But even then, mine survived whole summer of back-to-back flying.
Would you mind making a microelectronics basics video? It's fascinating to me how you can recognize the components and you know how they work (each single one, as well as together as a system).
Great video! Thanks for sharing! Is there a way to access de sbus signal before it gets inverted? My F4 FC doesnt have Sbus and I tought that maybe I could wire the Naked Vista from the Uninverted Sbus to a Rx in the FC.
I just broke the pos pad in a accident please tell me how can replace this pad and be able to make a alternarnate positive conection to give current to the board....
Thank you for making this teardown. Great info! Quick question about the heatsinks. Are the heatsinks close enough to the top of the chips to use a different thermal compound like MX-4?
help I broke mi positive pad en the vista I just try to scrape to find a point to conect but it has continuitu with the negative pad so I need yo know where can I put muy imput postive in the board please help....
Help. LOL I broke my ufl connector on my vista. My friend has the top board with different firmware and activated in his account. Can I use it ? Will I have issues with activation and firmware downgrade after install ?
I couldn't find relevant information anywhere so decided to give it a try here. I playing little bit with my Vista unit because have problem with DJI FPV Cam. I do connecting and reconnecting camera while Vista were powered. After that I notice that without camera my bitrate is about 10Mbps. Could no image to process cause lower bitrate?
Hello everybody, is anyone know how to wire menu board into vista polar ? Cause i want to restore factory settings for vista. Please show me where to wire . Thank you so much.
I have this unit and after only flying with it today after only a 10 minute flight, a few hours later I plugged a lipo in and straight away I had a strong electrical smell and seen a small smoke vapour come from the unit. At first I thought i must have a wire shorting to the frame,under close inspection, it was clean and tested on my volt metre ,all fine. Again i plugged the lipo in , light on the vista and immediately same thing smoke. What the hell had this bought brand new as a present in sept and have had to wait a few months fro my new frame to arrive from China. 10 mins flying and then this. What would you recommend I do?
Hi Livyu, I know this is a very old video, but I have a caddx vista with at least one of the voltage regulators blown (you mentioned that you suspected they're MPS... bQB5E or bQBSE?) --> Do you know the full component for it? Thanks!
I've been wondering the same - thinking about pulling mine apart and carefully applying some electronic grade silicone sealant around the outsides of the shielded areas + connectors to make the whole inside areas water tight.. But you're right it looks pretty good already!
Just lately I completely drowned my Quad into a big puddle and I needed 30mins to find it. It was powered by 6S all the time. My ESC and FC died, the Vista (stock) wasn't damaged at all. I opened it, no water or traces of water inside. Very good product 😁
Salut Liviu, Am o problema cu padd-ul de la Tx din pacate am reusit sa il smulg si nu am nici o sansa sa il pot conecta normal, crezi ca pot folosii padd-ul de la dioda TX? In mare alimentez de la regulator 5v deci nu ar fii sanse de spike. Te salut!!!
Hi Man! I am looking for a good but cheap soldering iron for microsoldering and your soldering iron in your video looks like its working very nicely. How long do you have this one? Any Problems? Can you quick change the tips?
My vista has recently stopped showing the OSD on my goggles, I contacted caddx, and they said that the core board has been damage due to excess heat... I've never left my unit powered on for long periods of time without proper ventilation. I don't think their "diagnostic" is correct, because I still get video in my goggles, so if the board was damaged, wouldn't it just not work overall? And if it is damaged, is there any way to replace it?
Salut!Liviu, mi-am prajit FC ieri dupa ce am conectat CAddx Vista la FC fettec . Dupa ce am investigat, am vazut ca am continuitate intre pad-ul TX si ground de la vista. E normal ?
