Hi Everyone, due to weather and some health issues the review will be coming a little later early next week. Thanks

@MCsCreations 8 месяцев назад

Get better soon, Ian! 😊

@Mr.Laidukas 8 месяцев назад

Speaking about naked version, you mention possible thermal issues. However you never mention possible RF interference issues. Which might be even bigger factor to consider.

@M-H433 8 месяцев назад

@@Mr.Laidukasso you think the housings reduce rf interference?...be good to know that actually interesting comment.

I preordered one and I can't wait to get it. I just got my HDZero goggles yesterday and even just using them with analog I'm amazed at the picture quality.

Thanks. I am genuinely Rough as hell lol.

@aviphysics 8 месяцев назад

I like how the PA is on a totally separate board. I wonder if it would have been overall thermally happier if there was more thermal isolation between the chipset and the power amplifier.

@starsstripesjacket 8 месяцев назад

Love your teardowns and explanations of the circuits!

@gmivisualsjason3729 8 месяцев назад

Looks very well thought out..... looking forward to putting one in a build. But definitely don't feel comfortable removing the heatsinks on this one..... Following with interest

Unbelievable work Ian!!! Thank you! Cheers!

Looks like there is enough meat in that centre slab to mill some fins into the sides of it to increase its exposed surface area....0.5 endmills though...shiver.

@Mads Tech What is your opinion on this VTX? Will it be as indestructible in terms of voltage spikes as Vista?

@ferocious_r 7 месяцев назад

But how many returns due to damaged/ripped off U.FL connectors will there be...

@nmrlab3807 3 месяца назад

Thanks for this review. Does this camera/VTX work with EMAX Transporter 2 HD monitor or frsky skyvision hd monitor?

@ugellin Месяц назад

your answer is but a quick google search away.

@Simofly 8 месяцев назад

Very interesting ! But why 2 power amplifiers ? Was it the same on the older version ?

@MadRC 8 месяцев назад

Yea it’s in a push pull setup to create the 1W of output.

@nikotttin 8 месяцев назад

Hi, Nice tear down. How would you compare with the vista thermals? I run mine makes for over a year and no problem at all. Frankly I’m impressed :)

@serval_fpv 7 месяцев назад

My naked Vista gets super hot need to get it in the air fast or have a fan on it while working on the bench..

@Austinpowers46 7 месяцев назад

just fyi for peeps the freestyle v2 and nano cam 90fps will not work with x20hd

@MadRC 7 месяцев назад

No I guess that limited to 60fps modes like the VRX.

@spacekip38 8 месяцев назад

i'd love to get into digital systems, but everytime i look at the costs of a full system (receivers and goggles are expensive..) i just get a little sad :(

@miquelmarti6537 8 месяцев назад

I was in the same boat. I sold my analog googles to get the hdzero ones and still flying analog only. Their interlacer is so much better than any other's googles.

@anarpearls9785 2 месяца назад

Why two PAs for a single antenna port?

@MadRC 2 месяца назад

They use a push and pull setup to get the high power output. So they work in parallel to double the affective RF power.

@anarpearls9785 2 месяца назад

@MadRC Thanks for the quick response. Really cool stuff. is there any schematic for this available openly? Also, wish to ask you: how do the high power vtx that provide variable gain options from 25mW to 2W do that when they are using a fixed gain PA with no control?

@miquelmarti6537 8 месяцев назад

a penetration test and comparison is what we want

@MadRC 8 месяцев назад

Between what ? 1W is illegal to use in most countries including the U.K. so I won’t be doing it.

@miquelmarti6537 8 месяцев назад

@@MadRC I meant btw analog and hdz. Sorry, I didn't know that and I already preordered. Do you know what's the maximum allowed power in the EU? Thanks

@mikeselectricstuff 8 месяцев назад

Bizarre that they're pushing the heat into the centre rather then the much larger surface area of the outside.

@miquelmarti6537 8 месяцев назад

I don't think they are pushing it, as heat will accumulate where it dissipates the slowest. Maybe a lateral rugged surface would have helped a bit, or not at all. I'm sure their engineers are much smarter than us.
