The RC805 5.8Ghz AV Receiver features a digital channel display and jumperless, one press channel selection. This receiver also includes an additional AV output for video recording while using FPV goggles.
** Many fake, poor quality & untested FPV products are currently entering the market. Don’t get caught out with poor quality substitutes, Boscam FPV equipment is tried and true and has been tested and developed by FPV pilots for FPV pilots.
Nanotech batteries are fine for this sort of thing but their big advantage is the high currents they can deliver, you wont be using much current. Save yourself some money, get the cheaper batteries with low C rating of the voltage and capacity you need.
ive managed to brake mine i think, by a monitor with red as - and black as supply cable, but the RC805 looks in working order ( LED displays working) and it does every think it should apart from showing a picture, could the reverse polarity of the monitor put a up the video cable to the RC805 in stead of a - ?????
Did you reverse the polarity for the power source to the RC805? or to the monitor? To reverse polarity to power the monitor you could switch the wires around and solder on the connector to solve that problem. You can't reverse the power source to power to RC805, for that will burn the RC805 up! Hope this helps!
I seem to get a grainy image when I connect this gear up to my LCD. Can't figure out why?? Any ideas? I use a 900Mh 3c for the TX and I plug the RX into 12volt adaptor to mains power and tested the camera. The image was ok but grainy??
Double check your antennas. I get grainy video when there is interference nearby, or my antennas are reaching the end of their range. If all the wires are soldered well and connectors plugged in, the antennas would be the prime suspect. Try switching them out to the stock linear dipoles and see if the video quality changes.Hope this helps!
My "older" one is 12V and the newer RC305 says 5v. I prefer the 12v because my video glasses use 12v, so I can power both with a 3S. According to a post on the 305, so are 5v and some are 12v even now.
think of this like that:
there 2 types of connectors and than, each of them can be MALE or FEMAIL
- if the plug is .... type male, than you need same type, but female.
SMA - (MALE) spins on AND has a "Penes" --> goes with SMA (FEMALE)- takes the spinning on and has a "hole"
RP SMA -(MALE) spins on BUT no "Penes"--> goes with RP SMA (FEMALE) - take the spinning on, but has a "Penes"
Works other way around, so if you have RP SMA Female ---> you need a man of the same type.
I hope it helps ;) if not, I attached a file look at it)
Yes. It's compatible with TS353, both have the same channels/frequencies to choose from* 5705,5865,5665,5645,5885,5905,5925,5945MHZ.
About the antenna, I'm a bit unsure.
Ferdia: Don't talk about stuff that you're unsure of/don't know. Don't mean to be rude, but people are using the discussions to decide what to buy, and due to inputs like your last one, people who are noobs will believe it won't work, which it obviously will.
The push button can be convenient if you often fly with other 5.8 users and the power LED is a lot easier to see. However the RC305 may offer more performance due to better plug placement (RC305 plugs are opposite the antenna, farther from the Frenzel zone which is critical for 5.8).
I tried mine for first time last night, hooked to 3S (12 volt) power. Marking on back says 12v input, while manual says takes input voltage 5 - 12 volt. Receiver got almost too hot to hold after < 5 minutes use. Will it remain enough cooler with 9 volt supply to be worth getting connector & adapter to power with 9 volt battery?
I figured even though receiver is marked 12 volt, since the A/C adapter that came with it says output is 15 volts, it should be able to handle the 12.6 volts of a 3s battery. Even a 12 volt motorcycle battery when fully charged puts out around 13.4 volts... Not sure if it's the camera or receiver, but tried it tonight, and rx picks up NOTHING if aircraft/camera gets more than 6 - 10 feet from rx!!! Fully charged Li-po cells hold 4.2 volts * 3 means MAX voltage of 3S pack would be 12.6 volts. My charger usually says pack's charged with voltage between 12.5 and 12.58 volts. Powered by 9 volt Alkaline battery the Rx still gets hot enough it would probably burn my leg if I used it stuck in my pants pocket!!!
The easiest way is to buy a TV tuner that connects via USB. Make sure the tune has a composite video input option for a direct connection to your RC805 receiver. Be prepared to find or create some adapter cables to match the RCA-type connectors but that's very easy to do.
you will need a SMA male to N female between the two. and ass far as range goes, the most range would deffinatly be a cloverleaf in the plane and a CP patch antena or a cloverleaf on the ground. a patch antenna would give the best range.
Have a look at electronicaRC They have RX with the wanted freqs.

This rx is not as well suited for FPV as the RC305. The reason is the position of the video and power connectors. The connectors WILL interfeare with the nearfield of the connected antenna which results in reduced range and altered distribution pattern of the connected antenna compared to the RC305. The other point of critics is the way the HF module is mounted onto the PCB. It's "diagonaly" soldered on, which leads to a not as clean trace path to the SMA connector as it could. On the plus side is the channel display and select push button, but it's value becomes a bit questionable considering the fact that one mostly only sets the channel once. The build quality is ok, and I belive for survailance / baby phone type of applications its surely ok. However, I recommend to get the RC305 instead as there the video/power connectors are on the oposite end of the rx and also because the (identical) HF module is soldered in aligned out with the lenght of the rx resulting in a clean trace path to the SMA connector. By dissasembling the rx one can see that the housing is also used for other products. This surely results in savings for the manufacturer but in this case is not of advantage for the buyer as most likely the compromise with having the connectors on one side of the housing is a result of this.
Got it as a freebie. Me likey. Now I have to buy a badass 200mW transmitter and go FPV. Sure a CP home made antennas is a must for good signal but I think original antennas should give a good starting point around 300meters for practicing. Quite light 44 gram.
