FPV Basics Flite Test

hey welcome to flitetest I'm Josh and this is Josh hi and today we're gonna do a basic overview of FPV a lot of stuff has changed with that you know with almost five years a lot of stayed the same a lot of change for the technology it's amazing it's just gotten better yeah cheaper too it's gotten cheaper there's better antennas out there yeah the technology the mainstream also the amount of channels yeah things you can put in the air at the same time there's even HD downlink that you can get now right so what we wanted to do is just give you guys a basic overview and a matter of fact that was a youtube request by periodic table of videos and he didn't even believe it was the real you talking so there's a whole forum thread saying it wasn't me we do actually respond to our videos I guess I gotta get a profile picture of me it does help I'm the things a lot of people know it's really me but yeah that's what it is are you really you I hope so we'll never know so you know this is gonna be basically a 10-minute overview there's give me a lot of technology we're not gonna cover in depth but we've also done previous videos that will link down below there's a lot of other really great minds but we really want to help you understand what you need to get into to get started with fpv right and also I machine to what's out there so let's talk about the set up yeah we're gonna need a camera cameras really important can't do much without a camera right need a transmitter and receiver yep to transmit in to receive well you got to have the camera transmitting to the receiver we're image yeah that's very good job speaking of your image you need something to see it on don't you yes I need some goggles or monitor or monitor yeah antenna antenna is really important antennas you know what I think some of the greatest technology jumps have been in antennas in the past couple years yeah it's amazing what you can get out of them and also with there being more frequencies out there the antenna is even more important than ever now we recommend for simplicity's sake that you go plug and play for your first setup plug and play is so important and a matter of fact with the growth of the industry the cameras and the receivers they're all interchangeable butt connectors they haven't really been solidified to companies we really like is immersion RC and luminaire right they have done amazing things in the industry to make everything plug-and-play but also the cameras their video transmitters they work on multiple voltages and that's really important so would you say it's a good idea to stick with a certain brand also find out what you like super important a matter of fact and I'll also find out what friends you have in the area if anyone's into fpv find out what brand they are using because the most likely they'll know that the best and fly that brand with them that way if you're getting new into it you'll get the most support possible from a friend now as a great man spider-man once said with great power comes great responsibility yeah the more power doesn't necessarily mean a good thing no no actually more power can actually hurt you yes with fpv a lot of people always assume the stronger the signal they get the better the experience in again but actually sometimes the exact opposite a better antenna with a lower power system can sometimes give you better cleaner performance okay so antennas matched up with the right transmitter matched up with the right camera is really your key to success okay that's what's going to be giving you the signal and give you the best opportunity to receive a nice good strong say especially if you're flying indoors right indoors yeah metal structure there's been times when we've actually flown like a Hercules plant where we've gone through and we had systems that were 600 milliwatts systems yeah and the multipath interference even though we're using helical antennas and we'll talk about that in a second but still bouncing all over the place coming back we had terrible static when we're flying these minis off of a 200 milliwatts system we had a horrible problem with it as well - applying a 25 millas system with a helical antenna actually gives you the best performance indoors because the power is not so great that the signal is imbalanced off the metal fixtures and then come back and hit you okay it's weak enough when it comes back you don't really notice gotcha so a lot of times also with multicopter racing and racing links for both wings and multirotors they'll even limit the power between 200 and 250 they won't even let 600 out of the door okay one thing I really absolutely love and it's legal to operate and fly almost anywhere is these little 25 mil awhile all-in-one systems a lot of people think they're not going to get very far with them but we have 10 acres in the backyard and we can fly that whole 10 acres and have a really good experience even flying through the wood school so this is all one you have your helical antenna 25 milliwatts system and a decent little 600 TV line board camera that all operates off of the same voltage that you go out of your receiver with okay do you need a hand why since you don't either helm license for that okay technically any time you go above 100 milliwatts you're gonna need a ham license to legally operate that system and it's not hard to get it's something you can you can do yeah but it's to be legal you know we don't want people being illegal strongly recommend doing that cool so we kind of touched on antennas yes soup important here buzzer these those are these a matter of facts in some of these - and some of them have seen better days a lot of times when you buy a transmitter you'll get something that looks like this and it works and if you're flying and learning off of a multi rotor and you're flying alone in a clean open area not rolling upside down or banking too tight you're going to get pretty good performance out of this but what happens is this sends out that's called linear antenna it's sent out of signals like razor blades right as long as you have something in the same orientation to receive it you're getting really good data problem is is what these guys go out and hit a wall or hit destruction and come back and you call something called multipath interference okay long story short you start seeing double colors get really weird it's not a good thing and also if you're flying an airplane or a multi rotor and you're doing flips and rolls you turn this 90 degrees that image data visually is doing this to your antenna and you're getting only ASP intance of what you had before I submit and submits army directionals work differently and a matter of fact this one's busted open you can kind of see what it looks like and also along here mm-hmm we really flattened the sucker out and this sends more of like a spiral yes single this is a cloverleaf antenna it's in that a spiral signal looks like a donut as far as the way it receives the only dead zone is right at the tip here okay and we have more videos on how antennas work here that will link down to below the long story short you can fly all around yourself with this and if you look at kinda looks like a drill bit going through the air doesn't it this actually sends the signal out in a rotating fashion now you want to make sure that if you have a right hand polarized antenna which this is that you match it with the right hand polarized antenna okay if you go right the left they're actually gonna cancel each other out and you'll get a little bit of an image but it'll be really muddy and it won't work very well right the reason they have left hand and right hand is so when you have all these different channels that we'll talk about shortly you can actually stack people closer together and right and left hand orientations to fly more machines at the same time it's kinda like a handshake yeah you're right you know if you both go with right hand it all works out if somebody one person is right here it's awkward so weird they cancel each other out that is beautiful you will never talk to him again and oftentimes if you go ahead and you match up your antennas properly one thing could be for range so you'd be using the patch antenna with another type of antenna that we receive that patch antenna well okay you know there's different tenants for different functionalities I'd really strongly encourage people when they're getting into this don't plan on flying miles out first of all it's not legal and you have so much fun in your backyard under 400 feet one of the last things you're going to want to pay attention to with antennas is there's two different types of connectors there's an RP SMA which stands for reverse polarized SMA connector and there's also an SMA our favorite that we still at our store and that we really like is SMA so we always try to stay with SMA whatever when you pick just make sure you stay with it whenever you're selecting the antenna be very sensitive about the connector that comes with because you could get the wrong one if you're not careful su-mei SMA now another great development is there's actually more frequencies to choose for a lot more frequencies so the most popular frequency is the 5.8 gigawatts gigawatts or whatever he kisses me yeah gigahertz and that opens up what four different bands and upwards of like thirty thirty-two different different channel there's a lot of different channels so does that mean you can fly 30 planes at the same time no what you have is different manufacturers came up with different frequencies that they were really tuned into Boz cam has their own band emergent fat track has their own band other manufacturers have their own band but ultimately there's about four main ones each consisting of eight channels doesn't mean you can fly thirty-two planes oh okay yeah what it means is you can put more planes in the air and you have the more ability to go on these half channels and these unique channels to get people closer together so now six people could technically race together nice and have a really good experience but it's really important when you're close to each other you actually when you're flying you carry extra sets of antennas you're flying with a buddy that has a real close channel swap out your antennas and make sure that you go to the left hand that they have right hand okay and vice versa also speaking of antennas always make sure that on your transmitter side you never power up your machine without putting your intent on first or it'll blow it up now on the ground you're going to need a receiver and a monitor which basically makes up your ground station otherwise you'll never see what the planes transmitting right and that comes in a lot different forms you have you have goggles that have everything within right yes and then you can also have a monitor with the receiver in it or you could have a separate monitor with a separate receiver yeah you can still go back to the good old days when we built our own you bought a receiver you bought a monitor and you hooked them all together or you dragged your mom's vizio out into the backyard it's always awkward when that happens all right so we talked about monitors let's talk about goggles goggles are the coolest yeah cuz you can put him on your face now you can get a lot of different size goggles to match your face right yeah everybody's got a different face everyone's a different face I imagine your face is like your foot it's everyone's different and you got to try them on you are ugly yep with the goggles nowadays are so many manufacturers out there and also they have adjustable eyepieces you really gotta try goggles on link you try pair shoes okay you got to try and make sure it fits also if you wear glasses you have goggles now that go over your glass real nice so a lot of different options out there a couple things you never want to do with goggles no matter whether they're cheaper expensive never turn them to light there's a friends'll lens in there and when the light goes through that it'll burn out the LCD display and you're done No so these goggles are pretty advanced they actually have a built-in DVR which means you can actually record your flight while you're flying really and change your settings and everything also oftentimes will output to another monitor so you can actually wear your goggles and you can tap it into a monitor and that way people can see what you're experiencing while you're wearing your goggles that's cool a lot of really advanced features and this one even has a family when I guess what the fans for that's pretty good I have nothing No so for keeping them from fogging up oh it's a hot summer day it's kind of humid outside these things fogged up and that was a big problem fat shark overcame that by putting a little tiny fin in there and actually powering off the balance connector every lipo that's cool and speaking of power the fat shark goggles also accept different types of power and they also have things like modules out table people to use head track and remember your head tracking episode mm-hmm so you can actually still do that to this day they're even more advanced and have I think more access I think you'd only go left right up and down I think it even has a rotate for the future and head tracking is when you when you turn your head it actually turns your onboard camera yeah remember we were at the golf course and we were flying the plane around and you're you're moving in all around yeah it's really cool yeah the functionality is even better there's no more drift anymore but it's really what you want to spend I'd strongly recommend if you're just getting into the Hobby don't go super cheap on goggles but read a lot of reviews there's supple things you want to make it pay attention to field of view the wider the field of view the more immersive the more narrow the more like you're looking into a little monitor through a screen right so if you want a really immersive experience you're gonna have to pay a little bit more but also the image is going to be a little bit fuzzier on the outer corners okay so it's really a payoff on where you want to go read reviews do your homework these are gonna last you for years but if you're building your own or picking your own monitor you got to make sure one thing you don't want blue screen okay you want statics okay static loose quiet why is that because blue screen just goes to blue screen and nothing else basically with static when you start flying away you're going to get an indicator that you're actually losing some of your image okay if you have blue screen you can lock out it takes a lot longer to come back in for okay so it's really important that you have a monitor that can go static not blue screen but also with the receivers nowadays there's a really great function where sometimes you'd have to hunt for your channels and you can find it a lot of these receivers nowadays have something called the search function so it'll find it automatically it'll go through all the channels and once it picks it up it will lock on to that sing to the best one you have to the best one sometimes you lock into your buddies but it still gives you a better opportunity to be able to find your channel also there's something called diversity and diversity was a really rare complicated thing in the past but now in these simple little monitors I love this this is a little issue monitor I really hope to see these someday with a flight test logo on I'm carrying their story sweet work fantastic but actually has two built-in receivers and it's always analyzing the signal whatever signal is the best it jumps to that antenna okay so ideally if you're going for basically flying all over your head and then you want to go for range you could have a patch antenna on one would you give you your distance and then you could have an omnidirectional cloverleaf on the other which would let you fly all around cool so when you fly behind you the patch antennas the worst thing you want but when you fly far away you wouldn't want this helical cloverleaf right so you can use that to your benefit and always assess the best signal work for you nice now with the receivers just like we talked about with the video transmitters in the cameras finding receivers that can work off of a wise voltage to the end will just protect your investment that way you can operate it from many different voltage power sources okay also if you have a receiver that can only recept five channels you're only ever going to be able down to five channels even if your transmitter can dial into more so you want to find a receiver that can accept every bit as many channels as your transmitter and match those right once again it goes back to sticking with if you want to go fat shark or immersion stay fat shark immersion if you want to go lumineer stay lumineer pick a brand and stay with it once a fast shark guy always a fat shark guy now this technology changes all the time change is really really fast and a lot of the stuff that we share today is based off of our opinion yeah so the best thing to do is to find people that are flying fpv around you ask them questions yeah reach out to the forums people's opinions everyone has an opinion about fpv and the best way to get into it build some friendships over this wine alone is not fun ya find some friends fly with them learn from them make a memory alright guys we'll see you next time
