Correction: I mean does PAL/NTSC systems corresponds to the swictch 4 down/up?

 Rangarid 276 points

No. It automatically puts out PAL/NTSC depending on signal from transmitter.

 davidTs 142 points

Thanks, I really like clear answers :)

Hi Anggara, This receiver will work with the TS353 400mw transmitter and the 5.8 500mw on the 5.8 tx/rx page. you could also get the same receiver that comes with the 200mw tx . as for the power rating the 1000mw transmitter will not give you twice the distance of the 500mw tx . The general rule is that 4 times the power will give you around twice the distance. Have a look at this site it will help you decide. ***********fpv.lt/lang/en/range-calculator/ Just put your details in the table and it will give a good idea of what range you might get. Also you can have the best tx and rx unit in the world but it won't work unless you have proper antennas. I would strongly recommend that you buy or make circular polarized antennas H.K have them listed in tx/rx video under 5.8 . Antennas setups are more important than the tx and rx units. Pour antenna = pour results. This Item has 2 AV outputs. Hope this helps. Geoff.

 Geoff 24 points

Just to add. If you use the rang check site just set the reciever to the RC302 rx. it is the 2.4G version of this RC 305 and just use the dipole antenna. you will find that 900Mhz will give more range for the same power but a good antenna will be large. Geoff.

 Geoff 24 points

Ha I need to learn how to spell poor and not pour....

 Anggara 3 points

Thanks for the answer geoff.. Just bought it along with 500mw tx :)

 Sawdust 1605 points

Actualy the answer to your original question is NO, it will not work with ALL 5.8ghz transmitters.
It DOES NOT match with the Imersion or Fatshark 5.8ghz gear.
This unit's frequencies:
"Channels
5.8G : 5705,5865,5665,5645,5885,5905,5925,5945MHZ "

Imersion and Fatshark:
"Channels:
5740, 5760, 5780, 5800, 5820, 5840, 5860MHz"
The rest of Geoff's information is good but he never answered your actual question. This will work with the other 5.8 gear here, just not Imersion or Fatshark transmitters.

 Anggara 3 points

Dear Sawdust, thanks for the concern.. And yess, you are correct. I found that there some channel group within This 5.8G channel. I got it now :) thanks..

 Sawdust 1605 points

Yeah, one sort of splits in between the other one's channels. I should have said Geoff never answered "that part" of you question too. Not that " he never answered your original question. Sorry Geoff.

 Geoff 24 points

No problem Sawdust,thanks for picking that up. Just noticed this RX says 5 Volts, I also have a 2.4 version and it says 12 volts. Further investigation reviled both units inside are identical a part from the actual RX module. I have run my 2.4 version with a 3S lipo for over a year with no problems. The Internal 5 volt regulator needs a minimum voltage of 6.5 volts input to work properly any less and you may get sensitivity or instability problems. Also the 2.4 and 5.8 versions use reverse SMA connectors, not sure if this was pointed out earlier. Anggara Today i tired my home made Circular polarized Skew antennas and got nearly twice the distance of the factory supplied antennas, especially when turning definitely worth it.

for goporo 3: usb, for the others is should be the "phone" jack.

 Sawdust 1605 points

This is a receiver, it doesn't connect to any camera. THIS connects to your goggles or other display device.

 Ben 22 points

*saw: right buddy. nobody doubts this. fyi read post below^^

 Ben 22 points

Sure, it works. You will also need a transeiver (tx) that works with 5.8GHz. Actually you also can find a set here www.link your goro you will also need a connector cable. you will find this at ebay.(search for "gopro fpv cable") probably you have to flash the gopro firmware, what is easy to do (with a usb cable. I also recommend to by better antennas. hope this helped you

This receiver works perfect the same as the RC805 ,the difference for the 2 is ,the way to alter your channel . This one has small flip switches on top of the receiver ,the RC805 has a on off switch that's also bin used to alter the channel's ,so if you turn on the RC805 you have to check if the channel is still the one you want to use ,if you push the on button a second to long you turn your receiver on and alter your channel all in one move. This receiver is also a bit smaller than the RC805.

 FRNFRN 139 points

The power plug is 3.5 mm. You can buy one from e-bay or a local electronics store. Bear in mind operating voltage (5 VDC)

 LUNDY 283 points

These receivers com in 5VDC and in 12VDC ,and Hobbyking is not aware of the fact they get differed voltage shipments delivered from there supplier. One time it's 5VDC the other shipment can be 12VDC. I have 2 of these receivers from Hobbyking,and one is 5VDC the other one is 12VDC .

Although this Rx unit is very popular, it is very nearly alway available. Check out RCSEARCHdotINFO If you search by product ID you can get some stock information from there. Hope this helps.

 dinislam101 87 points

Thanks for that, very good site.

 Kristopher 9 points

I've been waiting since early february

 MADDIVER 178 points

On stock now.

 QuadSB 431 points

As I have no equipment to measure, I cannot say for certain. What I can say is that I have several Tx's from different sources and when set to 5865MHz (or whatever), I can set this Rx to the same and receive. So, I would assume that what the numbers say are correct, probably... Hope this helps.

 fmorais 36 points

Same here, when using the same range of BOSCAM gear. Thing is the manual from BOSCAM doesn't list that frequency, instead it shows 5685. The reason for asking is regarding making antennas as I'd like to get as close as possible to the frequency I've choose to use. Thanks for the reply.

 Kristopher 9 points

Do you mean rc transmitter of video transmitter? It'll work with a 2.4ghz rc transmitter but for video it has to be a compatable 5.8ghz transmitter

 QuadSB 431 points

If you mean your control is 2.4GHz and you want to use the 5.8GHz for A/V, then YES this is fine. But if you mean you want to use this 5.8GHz A/V receiver with a 2.4GHz A/V transmitter, then NO it can't work. Hope this helps.

 ANGEL 1 points

Yes a 2.4ghz a/v transmitter. Thanks for the answer.

 QuadSB 431 points

You're right about that. I put a photo of the antenna connector on the RF module from this unit under the files tab. It's called RX5808 Ant Con.

 QuadSB 431 points

Hi Oliver, It'll work with the following HK transmitters, 500mW (PRODUCT ID: 263000003), 400mW PRODUCT ID: 263000007, 200mW (PRODUCT ID: 263000002), but NOT the ImmersionRC gear as they are using slightly different channels. Just double check on the available frequencies on the product page, I used the "5.8g 200mw FPV Wireless AV Tx & Rx Set" (PRODUCT ID: STCR351305), which is this Rx and the 200mW Tx. Also check with your local communications authority that Tx power is legal to use on the available frequencies. Hope this helps.

 QuadSB 431 points

Hi Christer, these units use FEMALE RP-SMA connectors. As found on most consumer WiFi routers. Hope this helps.

 Christer 2 points

Thanks man. Currently offshore working, so I didnt remember what it was. Im about to order special made antennas from f p v l r . c o m You should check it out, the guy is a genious!

 QuadSB 431 points

Sweet, some good looking gear in there. If I spend anymore money on this stuff my wife will kill me... I saw you were looking at the other Rx too, for what it's worth, I have this one and it's a solid little unit. I'd buy one again and recommend it to anyone.

 Christer 2 points

Haha. I just dont tell my girl anymore, im tired of all the bitching I get for my hobby:) So to be absolutely sure, I will need RP-SMA male antennas, right?

 QuadSB 431 points

lol. Have a look in a few minutes, i'll post a pic in the files tab.

 QuadSB 431 points

Scope out 'RX5808 Ant Con' under the files tab. Sorry, it's blurry as, but it's the best my stupid blackberry could do :( I couldn't find my RC305 Receiver, but that RX5808 module was removed from my other unit.

 Christer 2 points

Thanks for helping out a lost sailor *) Will order my antennas now, and hopefully they'll be ready when I go home again in 3 weeks.

 QuadSB 431 points

You're very welcome! Thank you for the credit! Now i'm 10c closer to the next think my missus will wonder what it is and where it came from...

 QuadSB 431 points

Hi Casper, what are you powering it with, 2S or 3S, or more? The voltage regulator inside is producing 5V and needs at least about 7.5V or so to work well. Anything over that is wasted as heat. So if you use more than that it can get warm, but it shouldn't be too hot. If the Vreg does get too hot it shuts down, hence the signal loss. I use a fully charged 2S in the field and 9V (or 12V for short periods) on the bench. If yours is still getting too hot to touch on a 2S, then open it and have a look if there are any shorts around the vreg chip. Hope this helps.

 Casper 67 points

I use a 3s lipo 11.1v but can i put 4xAA bat on it? (6,4v)

 QuadSB 431 points

3S shouldn't be a major issue, some guys are using that, I never used more than 9v for any length of time. From memory, the voltage regulator is a 78M05, it needs an input 2V higher than the output. I think there is a diode too, so add another 0.7V or so. 5 2 0.7=7.7V at least for reliable operation. That's the facts, the spec says it can operate on 5v, I don't see how! 4xAA would be too little voltage, try tapping into the balance plug on your 3S for 2S voltage. I'd also be taking a look inside to check for solder bridges, or any other issues. One of mine was perfectly beautiful inside, the other looked like it had been assembled by blind, reta rded monkeys using a clothes iron... Hope this helps.

 ggsolom 2 points

I tried a 1,5A 5V source(7005CT) instead of the 500 mA one. The temperature on 3S drops with a few grads.

 ggsolom 2 points

I want to say 7805CT - look to the file tab

 Crank 3 points

Hi. I will be locating mine(RC305) in a closed compartment* Would it be better for me to connect 5v from one of these "HobbyKing HKU5 5V/5A UBEC" after the vreg inside the RC305 to reduce heat from it? I have one concern about this BEC though* it's switched, will that lead to too much interference so that I would be better of with a linear BEC? PS! The BEC will be located in a ventilated area not too far away from the Rx.

 QuadSB 431 points

Hi Crank, That wouldn't be a terrible idea, especially if you have a whole load of 5V gear to power, but in that case, maybe remove the internal vreg if it's going to be permanently mounted. To remove the switching noise, think about something like an LC filter, (PRODUCT ID: 381000018) or there is plenty DIY guides around. Hope this helps.

 QuadSB 431 points

Hi Yurik, whilst it might be the antenna, you might also be suffering from some interference. Did you test out on different frequencies? I found that I don't get the same performance on all channels, all the time.

 Yurik 92 points

So what I mean: you can receive not bad antenna, but can receive BAD, so please check twice. Even if antenna is not broken, connector (outer part) is PAINTED from the inside (!), while it should be clear metal. And hard to remove this paint, So be ready to use another one...

 Yurik 92 points

No, I just have tested antennas and Tx with instruments. Video test would be next (still not received camera and have only mini OSD). I also have prepared cloverleaves. And here in Russia 5.8GHz is still almost free (hopefully!)

 QuadSB 431 points

That looks pretty ****py! I never used those little antennas that came with mine. I'll dig them up and have a look...

 Yurik 92 points

Yes, but the second is better. (A little better). And Tx antenna is better more.

 Yurik 92 points

You can take a look also to 263000002 (200mW Tx) Files. I have done tests.

 QuadSB 431 points

Hi there, over short range (ie testing) you should have no trouble in any orientation. At longer ranges, you might find that both antennae need to be in the same plane (horizontal or vertical) for optimal reception. But if you have issues at short range, maybe you have some interference, 5.8ghz WiFi, other peoples AV Tx/Rx, etc. Try a few different channels. The vreg inside should be fine at 12V, however it only needs about 7.5V to function, anything above it is watsed as heat. Some have reported overheating and shutting down at high temps. I havent seen that, I usually run mine from about 9V, not so hot. Hope this helps

 QuadSB 431 points

Then it'd probably be $30, and no doubt we'd all get a adaptor that doesn't fit our local power point... USB hands out only 5V, and whilst the spec says it runs from 5V, that's rubbish! It'll work well from about 7V, but anything over about 10V is just creating excess heat. Since you'd probably be using it in the field, 2S to 3S works well. I test my setups with a 2S LiPo and run it from the 9V output on my LCD. I've also run it for periods off 12V and it gets a little warm, but no biggie. Hope this helps.

 0Mica0 62 points

You can use 5V power supply (USB) only when you bridge internal 5V LDO (solder input and output pins of the LDO together. My RC305 have soldering jumper for this purpose...) but its on your own risk... The LDO is the only one protection against overvoltage in this RX!

 Lanius 110 points

Viene con un cable que termina en un conector JST de los rojos. Solo tienes que conectarle una LiPo 2S ó* 3S y ya está*. Si quieres enchufarlo solo necesitas ponerle un adaptador de corriente de entre 7-12V. Solo necesitará*s empalmar dos cables.

 DodgeHobby 177 points

2S is best (7.4v). 12v causes the Rx to overheat and cutout

 Lanius 110 points

I´*m using 3S and have had no problems

 ArrowFPV 1 points

I am using 3s as well with no issues

 QuadSB 431 points

It says in the spec, above that the input voltage is 5 VDC. This is rubbish! Inside (both of mine) there is a 5V linear regulator, so it can run from around 30-something volts, BUT keep in mind that the excess power is dissipated as heat! Since the VREG needs about 2V to operate, it should work most efficiently from about 7V or so. Hope this helps!

 marine 8 points

exactly the same problem!!!

 Lanius 110 points

I ordered mine last December 4 and I received it today. It took 23 days.

 ArrowFPV 1 points

It depends on the shipping method. I ordered mine and got it in a little over a week with EMS shipping.

 QuadSB 431 points

This Rx comes as pictured, with A/V, power cable and antenna. Pretty good value for a spare or building a diversity receiver system.

 QuadSB 431 points

Antenna is RP-SMA Male. Same connector as most WiFi router antennas. (but do not use wifi antenna, most are for 2.4GHz)

 Catalin-Nicolae 11 points

PS: On the back of the receiver it says: power suply: dc 12v.What would be the difference if mine works with both 5v and 12v?What to choose?

 Trikepilot 64 points

use with 2 or 3 cell lipo. I use both mine with 3 but they get a bit hot, planning to use with 2cell mounted to Fatshark goggles..

 G2loq 291 points

I have 2 of them and alway plug them with a 3s 12V lipo battery without any problem... First time I realise it is mark here as a 5V... as it is written 12V on my 2 items....
