Ultra-basics: Wiring a basic FPV system
HTML-код
- Опубликовано: 27 авг 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!
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.
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
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!
Pleasent voice, noiseless (( no music :) ) presentation ( +10 ).Ty for all your knowledge sharing.
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?).
Who's still here in 2021? Gotta love Bruce's white board classics!!
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...
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.
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.
Great vid! Some times all I need is simply simple! Keep them coming.
Great video Bruce, basic instruction videos are great for beginners. Liked and looking forward to more.
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
Walter White teaches FPV :)
Another awesome video!
Thanks Bruce. Very clear and easy explanation.
Cheers mate,
John
Thank you for making this video, now I can get fpv up an running on a new build. It’s my first, thanks again
May not be rocket science to you, but for a total noob like me, it was just what i needed.
Brilliant video as always.
Very nice draw mr Bruce. Keep up god job.
Keep up the good work! Love it!
Thank you Bruce made it so easy to understand
Thanks Bruce! This vid came at the exact right time for me!
"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
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.
love these types of tutorials, thank you sir.
Great video! Please, more white board videos!! Best!
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)
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 :)
Really helpful thanks for sharing.
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.
really good video helped a lot.
What about the receiver end?
First! Greetings from the Netherlands. Keep them coming!
AWESOME info for the beginner! maybe have links in the description to your other videos that way people can go watch more great videos!
I love watching your videos keep up the good work....
Great work Brucey, used this in my blog
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?
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
Great video Bruce this will really help people new to the hobby.

Thanks for this explanation, easy to understand!
Excellent lesson,,, well done..
Thank you I have been going crazy on how I was going to wire this.
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.
Just to be totally explicit. DO NOT connect a Fatshark or any 5V maximum camera to the 12V or "bad things will happen". There are cameras out there that will take more than 12V and still work all the way down to 5V making them very versatile. Remember to keep any documentation for any components you buy and match them to the specific components so if you later reuse a particular component you will have a useful reference when reconnecting it into another model with perhaps higher voltages like 4S or more.
Another neat feature appearing on some brands of VTX is a jumper to select 5V or Battery voltage out. These jumpers are not generally well documented so proceed with caution.
Even the most basic multimeter is almost essential for this kind of work. Plenty of videos here on the tube showing how to use a multimeter. For $20 or more you will have a tool with a multitude of uses in RC. Just don't connect a real cheapy to the mains.
Rob B And if the camera work on 5V and the VTX voltage out put is the voltage of the 3S battery ? How to reduce the voltage to 5V ?
***** From my experience most VTX's have a 5V out. But some also include an option to pass the battery voltage direct. If you are getting 12V out look for a 3 pin jumper on the VTX and move the bridge to the other side and you should now have 5V out. Just be sure to check before connecting the camera. If all else fails you may be able to get 5V from the BEC built into most ESC's or add a separate 5V ubec.
Rob B Thank you Rob !
Nice straight forward Video...cheers
Loved it my Friend!
Awesome. Got everything I needed from the video. The solder iron is heating up as we speak......
Well...that's hot.
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?
you may be old but you are a bad ass Engineer . thanks Bruce now I subscribe !
Thank you Bruce. Even my wife understands this! (ah oh; DID I SAY THAT OR JUST THINK IT )
Bruce I hope you can do a video in setting up a Minim osd.
Great video,as always!
Don't know what I would have done in the beginning with out you haha...
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..!!
@5.35 I think I heard a charger go off... Always Ready is our Bruce.. lol
Go old man you the best
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
don't forget the link to the sony 600tvl camera, bruce. please..
thanks for another great video.
excellent, its really hard to find some good content these days!
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 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.
Thank you Bruce.
........"Always put your antenna on, there are evil children in here. They will break your crockery and smash your windows."------- Love it!!!!!!
Thanks Bruce
it would have been great if you had continued on how to connect it to a monitor to complete this very good video?
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.
Thanks for your time on this vid and yr other one.s.my old racestar f4x4 aio dont have osd so i needed to learn this hookup method..thank.s again...cheer.s ron..i subbed to you allso..
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.
Hello i bought the monitor sologood and camera 3in1 TX 02 it's work but the screen not show the height speed and battery
You just got a like for your drawing of a camera! Enjoy. :)
Thank you very much for this video.
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?
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
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
Thank you very much, this really helps me a lot. :)
hey i have a run cam swift the yellow video wire that plugs into the vtx came out of the connector the white one. it looks like theres a piece of the eire stuck in the hole . do i replace the whole connector or can i depin it still?
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 ?
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.
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?
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?
Apropros the filter, does twisting the positive and negative wires together not have a similar effect in rejecting common mode noise?
I have Runcam Swift 2 and AKK X1 VTX but getting confused how to connect them with battery/together as the connectors are very different on both of these as well as is it ok to connect VID/GND of runcam to X1 VID/GND or the Runcam GND can be put into X1 power GND, please help me with this.
Hi sir. I wonder if you can help. I have a EACHINE FPV board camera on the back of this camera is a switch that can be switched up for P or down for N then a 3-pin socket I don’t have the plug with the wire this 3-pin socket would you know witch colour wire goes to each pin I know it’s a long shot just thought are ask. Thanks
A slightly off topic question, but what camera do you use to film your videos for your channel? Thanks in advance!
Amazing.
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!
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.
Trank You so much, You Helped me 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?
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
i have so much cables left... in dont understand it i have a Foxeer cat 3 mini and an Tramp HV as the VTX... pls help
how about adding an external microphone...would that be the mic's red lead to the Vtx audio lead and black to ground?
What happens if the video and the positive wires are interchanged accidentally?
Im not sure if most manufacturers use the same color code but they should. Then anybody can do it. Red to red. Black to black. Yellow to yellow
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?
How about a continuation video working with the goggles and head tracking for this setup?
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
