Ultra-basics: Wiring a basic FPV system
ฝัง
- เผยแพร่เมื่อ 20 ก.ย. 2024
- In this "ultra basics" video I show (on the whiteboard) the very simple basics of how to wire a video transmitter and camera together in an FPV system. Stay tuned and part 5 of the miniquad build video will show you the practical steps to do what has been shown in theory on the board.
BEST video I've EVER seen for beginners like me. Absolutely brilliant mate!
Great video Bruce! It is so easy a child can do it... I'm 15 and I did it yesterday! :D
( ͡° ͜ʖ ͡°)
ʕ º ᴥ ºʔ
I'm going to do this for my boeing 777 I'm also 15, lol
As a novice just in the research phase before building his first quad, your videos are a godsend. Really informative and helps take some of the worry out of a process that looks incredibly daunting to the beginner.
I love the whiteboard videos! My son and I (mostly me!) are following along with the budget miniquad build, and are learning a lot, thank you so much Bruce. As far as funding yourself, I'd rather see your channel keep the same open format, but perhaps supplemented with some sort of subscription for those of us who can afford it (Patreon?).
I really appreciate your continued support of the hobby. I, for one, find your information tremendously valuable!
Excellent video that still stands on its own 5 years later. Cheers mate!
Sorry Bruce, but I have a serious bone to pick with you! Since watching your "budget" mini-quad build I've spent over $1200 on parts to build one/several (I needed everything even transmitter and tools). You have seriously motivated me to not just watch all these videos of FPV insanity but to get my lazy, middle-aged ass into it. I've not been this excited, since being a child with a batman blow up bridge toy, waiting for my parts to trickle in. The next challenge is how to hide the expenditure from the finance minister (wife) but I have my ways.
Seriously. Thanks. Your videos are amazingly motivating and the retail people should be paying you a fortune to show there stuff.... oh, where did I put my Credi Card?
MashO Matic LOL! totally get you, way past the $1200 so i stopped counting how much i spend. As for the credit card, go grocery shopping and check out each item individually. This will create a bill so long wife will be lazy to read.

G'day,
You may be intrrested in a brainfart I had regarding R/C Models...; they almost all cost more per actual hour of Airtime than whatever actual Aircraft they're representing, and to even approach that then the Model needs to fly for at least one hour.
Eg, my son paid $250 for an Electric Pitts Special "Python", and if it flies for an hour then it's not far off the hourly cost of flying a real Pitts...; because it flew a 3-second Loop due to a frozen Elevator Servo, then unless it gets repaired and put back into the Sky to change the equation, it flew at a cost of $300,000 per Hour - and that's getting into Space-Shuttle like decadence...
This is why I still fly an almost 14 year-old CC Lee Falcon, it ticked over 28 hours aloft yesterday, so it's now worked it's Cost down to only $8.57 per hour..., including materials used in repairs (it's carrying 3 Ounces of Epoxy & Woven Fibreglass Cloth & clear Tape, 20% overload on the original T/O Weight of a Pound.).
How many Hours does a Quad fly for, before it's not worth persisting with ?
I'm waiting for a pack of 8 sets of new Prop's to arrive, before I even begin to try to learn to fly the Hubsan X-4...
;-p
Ciao !
WarblesOnALot I was thinking about that. If I had started again knowing what I know now what would be the two RC aircraft and RC equipment I would buy and keep and then buy no more. I'm constantly trying different foamy FPV planes and havn't yet found one I really like. Mind you I try and keep the costs down to a degree although I tend to use higher end FPV electrics such as ImmersionRC gear since its reliable.

G'day,
Thanks,
Yeah, I tend to operate off at the other end of the market, and the Cheapies are often so severely "Production-Engineered" to keep costs down that the sometimes fairly radical Aerodynamic Loopholes the Designer was intending them to fly through can be really small ; so it's a case of thinking really hard about how it looks as if it'll behave, prior to putting it up where it can crash, because a lot have only got one prang in them.
An outlier is a $50 thing called a Sky Hero, only 11.5 inches in length and span (so as to fit in a 1-foot box ?), with a Ducted Fan on each Wingtip, 2 Channels and incredibly twitchy in Roll...; but it does have digital proportional Double Throttles, with L/R Trim, so it can Maintain Level Flight, Climb, or Glide under Power while retaining Asymetric Thrust for directional control... (power-off it simply glides as trimmed, but it requires some Throttle or there's no "Turning").
But it's made from some "leathery" kind of Foam, incredibly tough, I've spent a day shooting one out of a Treetop with a Rubber Catapault and 1-Ounce Rocks and though it lost 1 Square Inch of Trailing-Edge at a Wingroot it still glided almost straight - though it had been hit so hard on the Radio Reciever the Wax was shaken out of the RX Antenna Coil... And it literally cannot fly fast enough, to be able to crash hard enough, to damage the Airframe.
A pity it needs Dead Calm to fly well, I actually got a second one to replace the one I shot the Radio out of...
So, to me, the Hubsan X-4 is a throbbing challenge...; if I muff it then $250 can fly away and disappear from sight in the Regrowth Forest I live in.., or go up and then descend too fast and succumb to Rotor-Decay, and arrive like a white Stone..., amidst the Bassalt Rocks sticking up in the neighbouring Sheep-Paddock.
Sadly, the first flight is always the riskiest, like the Pitts Python at $300,000 per Hour for 3 seconds.
I suspect that for $10 more, they could've built the Pitts out of the same Leathery Foam the Sky-Hero is moulded from, and it would've pretty much bounced off the ground undamaged, instead of shattering at every Stress-point.
Still, if it gets too scary, I can always have a few hours of fun with a well-folded sheet of A-4 Paper.... (check my "Aeromodelling For Children" Playlist, for the "World's Best Paper Aeroplane..." video, it has self-adjusting Variable Geometry, changing it's own Span and Area according to Airspeed, devilish cunning actually !)..., probably the most Cost-Effective Flying Model of all...?!?
Have a good one,
;-p
Ciao !
+MashO Matic .......... Oh.... I hear you brother..... in UK the finance minister (missus) is glad that I have a new hobby, but unaware (as of yet) about the costs..... I shall blame it all on Bruce too.
Great video. People like you make it a lot easier for the rest of us to learn. Top job...
Pleasent voice, noiseless (( no music :) ) presentation ( +10 ).Ty for all your knowledge sharing.
Hi Bruce, just starting in rc , and have found your video's not only a great help but a lot of fun. Keep up the the good work. Thanks a lot.
This type of video is very helpful. I'm a little dyslexic and find it hard to follow diagram an book stuff so this is a very good video foe me. Thanks Bruce.
Great vid! Some times all I need is simply simple! Keep them coming.
Love FPV so much that even though I've done this countless times in many configurations, I still watched and enjoyed it!!
eric deherrera Me too!
eric deherrera me three .. LOL
Me four :D
eric deherrera As did i lol. I am wiring my Minim and naze whilst watching lol
73, de M6EXH
FlyerDan Put a switch between the RX+TX wires from the naze otherwise you will have troubles when you try and hookup a USB to the naze, because they share the same wires. WIthout the switch, both will try and talk on the rx/tx lines and the usb wont work.
Always a pleasure to watch your videos Bruce, I have just orders the parts to begin my first FPV maiden flight.
Cheers
Great video Bruce, basic instruction videos are great for beginners. Liked and looking forward to more.
wow, you just cleared up any and every confusion I had with this! The video was great and your drawings were wayyyyy better than I could do :)
Who's still here in 2021? Gotta love Bruce's white board classics!!
Thank you for making this video, now I can get fpv up an running on a new build. It’s my first, thanks again
Thanks Bruce. Very clear and easy explanation.
Cheers mate,
John
I'm starting now in this world.. and I might say... This is an incredible video... well explained as the low budget FPV drone... it's a pity that here in europe is very expensive and we are having so much trouble with products imported from china... I've just one question... in which frequency does this VTX works. .. is it 5.8 or 1.4 ghz?
Thanks Bruce! This vid came at the exact right time for me!
Walter White teaches FPV :)
Another awesome video!
First! Greetings from the Netherlands. Keep them coming!
Thanks for the video. Alot of this is so confusing when you are a noob. Wish i had some nice videos like this when i was starting out. I think another very confusing thing for me was how to wire in the cheapo osd's. Some of them just "tap" the video wire and some actually sit in between the camera and the vtx. drove me crazy at first.
AWESOME info for the beginner! maybe have links in the description to your other videos that way people can go watch more great videos!
May not be rocket science to you, but for a total noob like me, it was just what i needed.
Some cameras have 4 wires Bruce. The white is audio in for the vtx. Most people ground it to the black. What are your thoughts?
Thanks for this explanation, easy to understand!
love these types of tutorials, thank you sir.
Many people want to select the video from their HD cam and flight cam which means using a switch. I've had good luck with the Turnigy switch, but others say some are better. Reviewing and comparing different switches would be great, and clearly explaining the wiring. That escapes some people, especially when voltages differ with some gear.
I know this is late in the day, but how about an audio feed if there is a mic in the camera? Thanks for all the great stuff. Particularly like the whiteboard bits.
Thank you Bruce made it so easy to understand
I know motors can make a lot of electrical noise. Back when we still used the old CRT TVs they would get static if someone in the kitchen turned a blender on or something. I am glad those days are over.
Brilliant video as always.
Keep up the good work! Love it!
Thanks a lot for explaining, sir!
Random comment..... I use Traxxas connectors... They simply work and don't stuff up.
(if somehow u broke it)
Because the terminals come out of the housing they are very easy to solder in the field and they don't require any heatshrink...
Maintenance wise they are years ahead... With a small screwdriver u can push the terminals out of the housing so they can be cleaned. This can easily be done on both male and female connectors.
The housing is easy to grip to disconnect the battery, no more pulling on wires
Current handling.... They can handle massive amounts of current draw as seen in the surface vehicles, I'm talking current draw a mini quad could only dream of... Things like a VXL stampede or a x01....
Bruce, u should try a Traxxas connector... Once u go black u won't go back (to red or yellow)
Great video Bruce this will really help people new to the hobby.

ATB Mate... :-)
What about the receiver end?
Very nice draw mr Bruce. Keep up god job.
Hi, I'm just getting started into fpv, not typically race drones or rc controlled stuff, but just fpv itself. I feel like I need to buy a basic setup in order to understand what it does, and then attach it to an rc car and drive it around the house. ETC
"There are evil children in here and if they don't have an antenna they'll wreck it -- they'll break the crockery and smash the windows!"
Best line ever xD
Great video! Please, more white board videos!! Best!
Really helpful thanks for sharing.
Off topic of this video but I'm needing some advice. Here's my scenerio... 4200xl excavator has 4 esc's. 1 for the hydraulic pump 2 for the tracks 1 for the turret. I just replaced the track and turret esc's with hobbywing wp1060s. All 4 are fed from 1 battery. So the question I have is about feeding power to the rx. Each esc has a bec. I can not find a definate one way or the other of whether i should remove the red wire on 3 of the esc's or not. Rx is a FS-IA10B. Please advise and maybe explain why. Thank you in advance
What are differences between the 600, 700, and 800 line resolutions, Pro's and Con's of course???
What do they cost??? What is 360???
What build do you recommend for each of them and do you have a link to buy them???
Please, keep making videos...
There's not actually a whole lot of difference between 600, 700 and 800 line resolutions. The limiting factor is usually the video transmitter/receiver and/or your video goggles. More important than resolution is "dynamic range" -- ie: light handling. Many of the higher-resolution cameras fall down badly here. Right now the best light-handling FPV camera on the market is the Runcam Eagle (there's a review on this channel).
Thanks! Nice explanation. Can you please help me with this? If I'm powering both a 'camera' and a 'video transmitter' with electricity using the same 5V battery (let's say), should I calculate the current and voltage consumption of both devices to ensure they are appropriate for the specific battery? I'm a beginner :) Thanks in advance!
don't forget the link to the sony 600tvl camera, bruce. please..
thanks for another great video.
A slightly off topic question, but what camera do you use to film your videos for your channel? Thanks in advance!
Bruce I hope you can do a video in setting up a Minim osd.
Because of the popularity and the generally-compact size of the gear, decent 5.8Ghz gear isn't spendy. I got a $42 200mW Boscam set and a $8 cloverleaf set and the link is solid. I got them off ebay and not to say that there won't be lemons on there, but it at least goes to show they can be found at a good price
BashMonkeyRC i agree thats why its a good idea at that price to buy a few extra setups.. i always try to by 2 Tx's and 2 600 tv line cams at a time.
I have a couple mini cameras coming from HK, only 520TVL but wide angle and good with low light so I'm gonna set those up on a tilt setup through the naze
I think most modern VTX cameras take positive from the VTX , not directly from the battery , is that due to a smaller voltage requirement of modern cams ?
I love watching your videos keep up the good work....
you may be old but you are a bad ass Engineer . thanks Bruce now I subscribe !
Awesome. Got everything I needed from the video. The solder iron is heating up as we speak......
Well...that's hot.
Hi Bruce - you recommend the 200MW transmitter for budget reasons but a lot of people who use FPV get the 600MW - my limited understanding is 600 MW gives you greater range - is 600 overkill or does 200 or 250MW (whatever the transmitter is) provide enough for the range of the quad? I want to buy budget but have ability to expand down the road. Also, I think in your video you said you would list parts in the decription - did you do it for this video or are you adding to the description for the first video?
***** I would say that 600 Megawatts is a bit overkill, 200 MW is probably enough to get you half way across the galaxy and already then you'll have to deal with some serious delay issues!
Thank you Bruce. Even my wife understands this! (ah oh; DID I SAY THAT OR JUST THINK IT )
I have a question? what's the point of the yellow wire, like I've seen fpv cameras without the yellow wire and so if I have only 2 solder points: a positive and a negative do I need the yellow wire and if so where would it go. Thanks in advance and great video!
Usually if the camera unit has only two wires (assumed positive and ground), it contains its own transmitter, no separate one needed. The yellow is usually the video signal going to the separate video transmitter.
@@55yxalaG oh now I get it thanks for helping the new guy out!
@@mr.animegod_yt No problem!
Thank you so much for this video. I’m wanting to try basic video and fpv with the runcam 2 flatform camera recently purchased. It all seems confusing but I guess its all being tailored for open platform where one can pick and choose their on preference on components.
Hello! I have a question but not exactly on this-
Why do antennas have a ground? It happens that i can't find the answer by simply searching for the phrase on google.
Great work Brucey, used this in my blog
Thank you I have been going crazy on how I was going to wire this.
So, what do you do next? Is there an sd card in the camera? Or the other video thing? Or do you use some kind of computer screen to watch? Or I’ve seen people use goggles. Confused?
Bruce as always good information and excellent quality.
Would you be willing to do a how to for noobs on mounting a rc plane motor, with vertical and horizontal angles explained, lots of stuff on vertical force angle to cg on wings, but none on horizontal, for instance my scratch build is flying to right side ... not to the left as expected. So spacing the motor etc... would really appreciate it.
I'm having a problem with fpv setup. Is it possible that a bad solder joint with the yellow wire will cause the video to drop out completely? I do receive audio, but that is coming from a microphone on my vtx.
I've got all the FPV bits but I still have no idea what to connect and where! No idea what voltage the camera or vtx is, I also have what I think is a fatshark filter that accepts 2, 3, or 4s input. I've no clue when it comes to electricity. I had assumed I'd solder a wire onto the PDB on the qav250
really good video helped a lot.
What about grounding the audio? for latency reasons I've read some where haven't been able to do it maybe a video of how and why?
Is the noise dependent on the signal strengt? What I mean is will it be more critial with a power filter if you're flying further away?
How about a continuation video working with the goggles and head tracking for this setup?
Some people still use deans connectors? LOL dem's fightin' words!!! Like I am stuck in the stone ages..bwahaha.. (maybe I am) I am just teasing. Thanks for the breakdown for the new fpv prospects. Love this channel... and Deans plugs ;)
***** hah.. I agree,.. I love deans plugs,... I hear people putting them down constantly, saying they come apart. I've never had an issue, and if you retighten them every few times they will last forever. so much better than plugs that are so hard to connect/ disconnect, that when you want to disconnect quickly you often over pull and cause stress on the batt and model wiring. I like that I can connect/ disconnect with one hand, especially when I'm doing ESC calibrating on the KK board. Deans all the way..!!
it would have been great if you had continued on how to connect it to a monitor to complete this very good video?
Hey so I have four wires coming out of my camera.. red white yellow and green? I can't figure out what they do.. in getting no image on my goggles. Just black screen
I have a camera for an larger drone that I recently broke. I am trying to connect it to a mini drone to fly fpv. The battery and circuit board are too heavy for the small drone to carry. How do I connect only the camera to the small drones circuit board?
I recently ordered ts5823 from banggood and hk, both died in 5min (power regulators on the board, since they worked with 2S still) got replacements and again, both same story, 5min and than 2S only. All 4 were 1.2rev... I ordered new boscam 350mw instead now, waiting if that thing is any better. Did you get good one Bruce?
Bruce, My transmitter supports Audio, my camera doesn't have a microphone. I want to add a microphone to the transmitter. I'm not sure how to go about it. I see mics on Banggood, etc, how do they need to be wired into the transmitter? small barrel microphones with 2 wires coming from them do they need to be powered separately, resistors added or simply connect to the 2 wires from the transmitter?
What happens if the video and the positive wires are interchanged accidentally?
Great video. Thanks.
Quick questions.
My fpv cam has no mic (and the other one I have had a crap mic)
My VTX has a green wire for a mic input.
I have tried two different mics wired to the black and green wires but get no audio on the headphones on my fatsharks.
Every video I've seen shows how to wire up the built in microphone in the fpv cam but how do I wire in a sepereate mic?
Thanks
Andy
Hello i bought the monitor sologood and camera 3in1 TX 02 it's work but the screen not show the height speed and battery
I have a Quad I dismantled for parts and a new quad that I fly (same type). I want to put my spare FPV Camera and VTX from 1st quad onto my Radian 2m Glider. Mounting it all is fine, I have a plan for that. I just wondered, what would you do for power to make my VTX and Camera work? Would you put in a 2nd 3S to run them or would you make a "Y Connector" with XT60's to split the power from the flight battery so it powers everything? Or do you have a better way than these 2 options? Sorry, lots of "?'s" - your vid has certainly helped me understand the power supply thx. The Quad is an Eachine Wizard X220S, 700 TVL Camera and VTX has all the bands it's a decent one.
Apropros the filter, does twisting the positive and negative wires together not have a similar effect in rejecting common mode noise?
Hi.. thats very good and detail explanation ....(*****).....I have a question Sir....I have built my qav210 using matek F405 STD. (installed also low ESR caps on main Lipo power and all ESCs. For Power the vtx and cam, using 12V direct from PDB --> micro LC Filter 3A and common ground for Vtx and Cam, offcourse V in and V out wired into F405 itself.. I'm Using AKK Fx2 and Sony Had II, Google Eachine VR006 and Fat Shark Spiro net Mushroom Antena (I didnt know whether this is a clone FS or genuine...one?? ;)))).
What im so confuse now,.....How to get a super clean and strength (Not Long range) video receiving signal ?? because during flight the receiving signal is not good..I mean video is clean but weak signal ..could it possibly the fake antenna? or should I replace them ??? pls help regarding this matters....since video quality is crucial for me during flight. I dont want my quad has around 1 km and the video signal is blank......thats not good i think.
thanks and rgds
I have been using fatshark fpv equipment for a long time now and wanting to switch camera and vtx (immersionRC). I noticed the pzo420 runs on 12v.
So my question is... running a 3s lipo will have no issues, but if I ise a 4s lipo, will I need a 12v regulator for my fpv? And if so, any recommendations for a fpv racer?
Loved it my Friend!
Thank you very much, this really helps me a lot. :)
Could you do a white board diagram on wiring up an OSD. I am using a Pixhawk with a Fatshark system and I want to put in a Minim OSD from Banggood. I am having trouble wrapping my brain around it.
I have not been able to build any fpv setup without power filtering, what is it about this setup that causes you to not need it?
AndyRC sometime the filter is built into the vtx. i agree, i have not had one of those, and i end up adding an LC filter every time.
Great stuff!! Now can you do one for an OSD as well? Thanks again for a very informative video!
hi iv just built myself a fpv setup with a base station I'm using a bosecam RC305 receiver and TS5823 transmitter but I just can't figure out these channels lol I tried matching on ch7, 5925 and I tried reversing the dip switches but I can't get them matching
Excellent lesson,,, well done..
Hey Bruce, How careful do you have to be about running your video wires close to the ESC?
I need help wiring a Discovery buzzer to my Qav250. My setup is the X8R Fr sky and X9D taranis- plus tx. The instructions for the buzzer are quite vague. It says plug into an open channel (e.g. Gear) on the receiver, toggle a switch and it should beep. I can't seem to program my tx for this function. Please help.
Can i ask where can i put a sd card? so that the video will directly go at the sd card
Im just a kid wanting to learn about these kinds of things
You should probably point out that the white wire on the VTX is for audio input, and is not required; it should probably be cut off, or the pin removed completely from the housing.
James Brown I always see the wire and keep thinking to install a microphone to hear the quad. This can give you early signs of issues, for example i got 1 prop barely hitting the video antenna at some point.
Hi Bruce love the whiteboard concept.
Can you explain how to use a Gopro 3 black as the camera in the Fpv setup?
I also found a backup monitor and camera I had, can I use them? The monitor is for 2 cameras..lots of wires?..
Thanks
Be nice if you showed what the actual components look like or dont you have them yet? Good job mate.
Hello Bruce, first of all thank you for your precious explanations! I would ask you if in wiring a basic fpv system, I can take power from the balance connector on the main battery wich I will use for the esc controller and for the camera and video transmitter. I think that, if it is possible, would be a clean solution in wiring cables instead making joints on them. Best regards and greetings! Andrea.
Nice straight forward Video...cheers
can a 5.8 ghz antenna be made bigger and put on my roof with a long wire to me and my goggles? I know they are small because of the wave length but if an antenna can be made quarter length why can't it be made double length? or can it? how about 100 times length. seems like more antenna should pick up more signal and on the roof should give the best coverage of the whole yard.
Hi I'm new to the drone world.
I'm trying to set up my FPV using a FX X40 5.8ghz 40CH 200mW transmitter.
My question is are all servo connectors the same size if not how do I determine the size I need?
I need a male 3wire servo connector so I can solder it to a 90 degree micro USB cable to use a action cam.
