CaddX FPV Goggles X Overheating Explored - What Is Going On? 

Not just you Same here and in RF standby mode. Just add a hot day or even direct sunlight, mix in 700mW of rf power and we have 🥵 😬

Doesn't seem to happen to everyone, I would go for.the exchange.

@@fpvsmurf Not everyone has tested them good not even caddx in the first place

Wait till summer. I’ll have my popcorn ready. This will definitely be interesting

I see Caddx is offering the heatsink for free, to buyers of the Goggles X, and the new production run includes it. From their site: _"This link is only available to users who have purchased Goggles X_ _We send the hot plate quantity based on the transaction record of the customer purchasing Goggles X. (For example: you have 2 goggles X, you only need to buy _2pcs heatsink, multiple purchases will not be shipped)._ _The latest production of goggles has been replaced with heatsink, so users who have not received the goggles X don't need to purchase heatsink again. _The price is only temporary and not the actual selling price."_

Yeah the IPD definitely isn’t wide enough

It’s either Analog or HDMI mode. Either.

@@MadRC Thanks buddy.

Agreed, I will be doing mods as well.

​@@spockfpvto be honest. I'm thinking of just cutting some of that wall that blocks it from getting to the front of the goggles. And possibly open up some plastic to get more airflow towards the front as well.

@JaWizard I would sure like to see your finished work. He will give me some idea what I should do on my end. And if you see a difference.

No it returns to normal once fully left to cool.

​@@MadRC You said it draws air in through the two facier vents. In your tests, within the printer. That area was obviously open. What about when people are wearing the goggle. And their face firmly blocks any air that can be drawn in through those vents?

VTX needs to be on

@@MadRC Thanks. Happy New Year

65c is definitely hot but still below the max however that’s not good. How long does that take to happen ? There is a new FW coming out you should try first I may help the issue.

Takes about 40 minutes, after 60 minutes there is a small amount of image 'tearing' at top left of the right hand side module. I stopped the test at 60 mins as I didn't want to destroy anything. Also the goggles were not pressed against my face for most of the test (but I covered the prox sensor with my thumb to keep the displays active being careful not to block the node vent), so those vents inside the goggles should have had good airflow. IMHO the more the components are cooked, the shorter will be their lifespan. As I fly planes for longer than 90 minutes at a time these are not going to be suitable as I don't want to have a failure whilst my big talon is airborne. My tests were in a 21C room. I assume on a nice sunny day (yes sometimes we do have those in the UK 😂) they will fail earlier. What's interesting is that you say the oleds are rated to 90C, but I am seeing discolouration well before that temperature. Discolouration first then dimming as the temp passes about 55C. Additional observations are that if I bump up the resolution to 1080p and also then frame rate, the temperature increases slightly quicker - hth. Honestly I think that pushing a product out in this state is a sure way to get lots of returns and a loss of reputation. It's not up to the community to debug and attempt to fix problems (Just my 2p worth) these goggles + 3 vtx's and antennas and I'm up to nearly £1k of outlay. When I spend £1k I shouldn't have to go debugging and waiting around for fixes. I do understand that HD fpv goggles are a niche product that present a unique set of difficult design problems to solve, but my statement still stands. When a customer shells out a big bunch of cash and they ship with a fault that could impact the safety of a flight then they are unsuitable. They said, I'm sure they would be fine for flying my quads as they would get time to cool down between packs. But for us aircraft folks who like a longer flight then nope. I received mine just before xmas. I did notice that they went out of stock and I ordered on the second restocking at a UK based reseller. Maybe there is a difference between first & second batches. Such a shame as I had high hopes for these. Thanks very much for actually doing a video on these - great research on your part 👍 actually acknowledging that some people are seeing the issue is nice to see. I noted that the facebook discussion on the overheating issue seemed to get quite 'heated' and just because some users dont see the problem, it doesn't mean that it's not an issue 😉. Samples of 1 aren't particularly good science - something you have paid attention to 👍

@@threebadmicefpv watch the video back he said and showed the specs for the oleds and he certainly did not say 90 degrees that i recall, operating temps between -20 and +70 time stamp 13 minutes if you want to go look, i do agree with all your other points tho, spending 1k on toys is a heck of alot for us on low pay with families and mortgages to pay and offen its a big decision to purchase such a thing. I very nearly bought these before xmas too but decided to hang fire a bit to see what happens with them over the next few months, i sold DJI v2 ages ago needed the cash so now im just running hdzero, was hoping these were my way back into high pic quality digital but the lack of screen demisters i think maybe an issue come summer, this is why i didn't invest in Goggles 2, i tried a friends on a winters day and fogged up in less than a minute what a nightmare it was to fly. really hope they get their shit together i imagine there are alot of people dissapointed right now. hopefully they got your back and come up with a decent solution and not some half assed effort.

@@Loz348 Ah my bad 🤦‍♂️with the 90C good catch 🐟 Yes it's a lot of cash indeed!! I was a bit nervous when I shelled out for my analog skyzone 04x's (v1's) a couple of years back, but thankfully they have excellent and haven't missed a beat, only problem i had was 'mix mode' on my hx115 hd toothpick, but on diversity mode they've been great. Bummer on your DJI's but needs must. I'm going to try & get the reseller to swap these goggles x with the v1 otherwise I will be left with 3 vtx's and no receiver. Was tempted to get the vrx unit instead, but thought the extra vertical pixels would be nice. Happy new year 👍

@@threebadmicefpv I had the 04x v2 and i do agree a great product but analogue didn't have the temp issues all these new digital gogs produce, its obviously a design flaw which is a big shame cos on paper these fit alot of peoples needs, i have been and am still tempted to get the walksnail vrx and just velcro it to the hdzero gogs if im honest, not sure if hdzero sorted out the compatibility issues with certain modes but i may take another look in near future.

Not in this scale no

@@MadRC Seems to be a lot of issues with this HD system Ian,1 I will never buy,not this model anyway,thanks so. Much for the work you do for us ,I assume they look at your videos for sure and I would think it's about time they wake up to themselves,you should be compensated by them in some form I feel.

I have DJI Goggles V2, and HDZero Goggles. Neither have ever had any issue at all, temp or otherwise, even operated in direct sunlight and up to 37C in shade ambient so minus solar gain (UK practical max before I crawl into a corner!!). Neither do my analog Eachine EV200D, EV100's, or any of the seven types of budget headset I run. Personally I think black is a very bad choice for goggles, esp HD ones, and looking at the designed airflow paths of the CADDX unit (if that is what you can call them!) its no surprise they suffer. Hot air rises, heated air expands, seems to me CADDX lack that schoolboy basic knowledge, or are they THAT sloppy? 🌡

I've just tried the new firmware, and it does help resolve the overheat issue.

where did you find v37.x.x firmware?

@@MineServersSKCZ drive.google.com/file/d/1MjJKs_gJuztNyPUdGXXVDpM_UfSBCxzd/view

They will fix it with their magic wand!

Yea, they all live in Siberia.............. 😁

The unsuspecting buyers are the test pilots!

Try turning off the proximity sensor in the menue and see how it is. You can calibrate this as well

​@@MadRCI think that fixed the problem. I updated to 36.40.4 and now I'm noticing the right screen gets a little dimer then the left side after the goggles are on for 20 minutes. I tried holding a fan up to them but the air coming out still felt really warm and the screen didn't change. Played with brightness level checking 1 through 10 and both sides changed but the left side stayed a very noticable 20-30% brighter. I let then sit powered down for 30+ minutes and upon reboot they seem even again. I'm really thinking one is overheating.

I think there are some now on thingiverse, but should we have to go to these lengths on a new product out of the box 🤷‍♂️

He is using the infiray. I have one and it's brilliant & affordable.

It will happen on any voltage as far as we know.

Was running mine on mine on 3s lions that were already partially discharged, about 11v, after 40 mins and right hand side goes yellow, an hour and I get weird screen tearing. I figured if I used more volts, and there were linear regulators in the goggles it would make the situation worse. Didn't fancy dropping as low as 2s though - however if they'll _reliably_ run on 6v I'm willing to try it

@@threebadmicefpv however maybe less volts, more amps, more heat

True in some cases, but In my experience linear regs usually get hotter the more they have to drop the voltage, the excess energy is dissipated as heat (well certainly in the case of regs like the old L7805 / LM317) Disclaimer... I've not taken these apart so I am only guessing theres a linear reg in there

Yes however there is marginal difference, the problem is I cant show the temps in the other modes.

@Madtech I made a V2 with the cooling channel nearer the face blocked off. Maybe this will help the hot spot seen on your thermal video. I still don't have my goggles and I understand that not everyone is having issues with the heat. I've been off work and bored. haha

I agree

Except they completely refuse to recall it or refund you they will tell you to wait on a fix they have a fix coming which is honestly bullshit when you're paying this much for something and it doesn't work out of the box or having issues you should be able to send it straight back to a manufacturer and tell them fuck off and use somebody else

@@lifebehindtheselens agreed that’s how the commies roll.

I had uploaded the wrong video. The new one is the correct one. There was a slight edit.
