 What's up guys welcome to Rotorite and welcome back to learn to FPV. On the last episode I did an overview on all the different parts that go in your drone and on this episode I'm going to do a quick overview of the parts that stay down in the ground with you So that's your radio your goggles and your charger The main difference from these parts to the parts on the drone is Drones can kind of come and go you're definitely going to crash it You're going to break them it could have a flyway could be stuck in a tree and you could end up with a whole Multituted different drones, but with these parts This is something that you're going to use all the time no matter which drone you're flying You're always going to be holding that radio when wearing these goggles and every time you need to charge your batteries You're going to be using this charger So when you're picking different parts to build your drone there's corners You can cut you can go with different cheaper components, but with all of these things I really recommend get the best one that you can afford and don't buy it multiple times over save yourself the money With that said let's talk about radios a little bit in the simulator episode I mentioned that the QX7 is in my opinion overall the best bang for the buck radio, and I still do believe that But different people prefer different things and there's different price levels So well, that's only a hundred bucks and it does everything you need Maybe a hundred is out of your budget. So there are cheaper radios. It will also get the job done There's also more expensive radios So maybe a hundred dollars is nothing you and you don't mind spending five hundred Maybe you don't mind spending a thousand. Maybe you don't mind spending three thousand dollars on a radio Everybody's different people have different budgets So the main different brands you'll come across in radios are fly sky FR sky spectrum and Futaba So if you're looking for a really cheap radio, those are going to be your fly sky radios They work perfectly well. They'll fly the drone. They'll get they'll do everything that you need them to do Just the overall quality of them is a little bit cheaper I don't think there's as many good options for receivers as you're gonna see an FR sky Some of them are kind of big and clunky, but they do have some good receivers for them So if you're on a tight budget a fly sky radio is definitely not a bad way to go in the fly sky brand But a little more expensive a little bit nicer. You've got this radio. This is the nirvana So this is kind of like a more radical design the ergonomics of that are really nice. It's really different But some people may think that's ugly some people may not like the way it feels it's it's really just depends on you and If you have the opportunity the best thing you can do for both radios and goggles See if there's any local events near you see if there's a multi GP racing chapter and Go and meet some people and be nice talk to them and ask them if you can hold on to their radio Get a feel for what it feels like in your hands if you can see if you can look through their goggles and see which ones you like So I don't have one here with me right now, but another really good brand of radios is spectrum Spectrum has a really nice feel. They're built. Well, it's been around for a really long time And another upside to using spectrum is if you like to fly airplanes There's a lot of bind-and-fly models that will be ready to go for spectrum I'd say that spectrum and FR sky are kind of the Ford and Chevy in the radio world So some people swear spectrum is better. Some people swear FR sky is better They're both good radios and traveling around meeting different people. I've found that they're sort of like pockets Some towns I've gone to every guy there is using a spectrum radio other places pretty much everybody's got the qx7 It really just depends and it's probably not a bad idea if you are flying with a group of other guys Use similar gear to what they have that way if you have problems they have experience and they can help you out So spectrum has a wide range of radios some are going to be cheaper less functionality but a lot more affordable Some have a lot more features and they're more expensive And while we're talking about high-end radios You also have futaba. So futaba has been around a really long time. They make really high quality products, but They're a lot more expensive. Whereas this radio is a hundred dollars I think I paid about 500 for this one and they have radios that go up to like three grand It just depends on the person though different people have a different budget So for some people spending a thousand or two or three thousand dollars on a radio It's not a big deal. They have the money to spend other people. They're not even trying to spend a hundred They're they're going for that $50 radio but at the end of the day Any radio is basically going to work as long as there's nothing faulty with that radio and it's broken The sticks will move the drone. It's it's not a big deal. Which one you get But I do recommend get the best one that you can afford because again This is something you're going to hold every time you fly no matter which drone you're flying Okay, let's talk about goggles There's two main different types of goggles that you'll find. So you have your box style goggle and your goggle style goggle. I guess I don't know if we really have a name for this So usually the box goggles are going to be a lot cheaper And these goggles are going to be a better form factor. They're lighter They're more comfortable to wear and you look less like a dork. You still look like a dork, but you look less like a dork with these So besides form factor, the other main difference between the two is a box goggle is just going to have one screen inside of it Whereas these style goggles have an individual screen for each eye That's kind of where your price difference comes in because it's really easy to source a small lcd monitor and stick it in a box That's a really common device that you find everywhere But I don't even know of another purpose to have these two individual screens like that so it's a much less common screen and Getting all that fit into a tight space. It just drives the cost up But there are upsides aside from the price to going with a box style goggle with these Not everybody's eyes will work with them depending on the the spacing and the the actual their actual eye sight They might never be able to get their image to look right in those goggles So having that single screen on the box style goggles is going to be a little more forgiving for different people's eyes And fattrack actually has some of these newer ones. They're they're really not too bad. They're not that big Compared to something like this. They're a little bit smaller And the image is actually pretty good on these One major advantage to going with these style goggles are they have more different options for what kind of receiver module is in it Typically on a box style goggle, you're not going to be able to change it. It's just built right in So I can pull this antenna off But I cannot change that that's just built right into the screen And not only that but both of these goggles here. They only have one antenna whereas these can accept two This is something we call diversity What diversity is is essentially that receiver module has two receivers in it So there's different ways that can be used One way is You can have different types of antennas on it. So some antennas are called omni directional So you can think of it as working like in a globe. So no matter which direction you go You're going to have equal range in that direction Other antennas are directional. So if I were to go this way, I'm not going to get a whole lot of range But if I go this way within the beam of that antenna, I can go a lot further than what Omni directional antenna will give me There are some box goggles that have diversity receivers But typically the performance you get out of the ones that you can stick into this type of goggle are going to be a little better So how the diversity module works in that situation is Depending on which antenna is getting the stronger signal the module will automatically switch back and forth between those two receivers Some of the newer modules like the one I have they actually have a different way of using those two receivers Instead of jumping back and forth from one to the other It actually takes kind of the best of both signals and then interlaces them together So that's going to overall give you probably the best image you can get So just like the radio, it's going to be a smart move to go ahead and just get the best goggles that you can afford Because this is something you're using every single time you fly And it can be frustrating if you're not getting a good signal from your quad If you can't see well, you can't fly FPV well Okay, let's talk a little bit about chargers There's two main different types of chargers that you can get So you're going to find ac or dc chargers With the ac charger you can take the charger and plug it directly into the wall Whereas a dc charger The charger itself is not going to do anything. It doesn't have a power supply built into it So you need to also buy an external power supply. Whereas the ac charger has the power supply built into it There's pros and cons to both So typically your ac charger is going to be less expensive Some of the power supplies you'll find out there can get kind of pricey. This one in particular is a pretty good deal But the downside to ac is it usually has less power So less power is going to be longer to charge your batteries or the less batteries you can charge at once Another thing to look at in different chargers is how many outputs or channels does it have? So this charger has four channels So it's essentially four chargers in one Whereas this one only has one But the downside is each of those four is capable of putting out less power than what this one is So depending on what batteries you're charging and how many you're trying to charge at the same time It may take longer on this one Another thing to think about when you're looking at chargers is how many amps is it capable of pushing out? And what's the total wattage is it capable of? If you're not familiar with how voltage amperage and wattage works They're all connected. So wattage is equal to volts times amps The reason why that's important is if a charger says it's 10 amps, but it's only a 50 watt charger It's going to depend on the battery that you charge whether you can actually get to that 10 amps Because they're all related So the more of the cells in the battery the higher the voltage if the voltage is high the amperage is going to go down So maybe it says it's a 10 amp charger But you could really only charge a two cell battery at 10 amps And if you were to put a three cell battery, maybe you're limited to seven and if you were to put a six cell battery Maybe you're limited to two amps so Both of those are important and it's really important to look at the wattage Because ultimately that will be the limiting factor on how many amps you can push out So speaking of power almost always a charger that requires a separate power supply Is going to be capable of pushing out more power So what that means is you can charge more batteries at the same time and you can charge them faster So just like the radio and the goggles the charger is something that you're going to use every single time you fly So it's a really good idea to do your research figure out which charger is going to meet your needs and grow with you You can buy a really cheap charger that'll get you in the air today But chances are as you get more into the hobby and you have more batteries to charge You're probably going to end up replacing it So that's going to do it for today later on in the series. We'll have another episode that's all about Using the chargers and how to charge your batteries properly So thanks for watching and this has been learn to fpv
