Um and show you go over some details of them show what they do and show you. Some cool features that this one has that others don’t yeah yeah there you go all right. Like always.

The entire east coast of the country also check out our facebook group um a lot of tech support, help stuff like that. We got a pretty good little community yeah everybody’s, helping each other out. Everybody’S been really good, very helpful in it, alright guys. So today we have a bunch of new receivers from radio master we’ve been waiting on these for a hot minute. Now they finally came in and now it’s time to show you guys some of the various ones here we actually have more coming on top of this i’ve had a ton of calls asking what’s what which is which, which one do i get so let’s go over. This so let’s start with the basics. Here we have various types of receivers. These you can see, have servo, pin headers. Well, you can’t really see it, but these have servo, pin headers for airplanes and they can be used as drones as well um. These right here we’ll talk about a later time.
These are actually s bus, only receivers, so those are mostly for drones and flight controllers. So today, we’re gon na just get those out of the way and go over the three main ones that we have here for airplanes, all right, okay, so what we have here is the r84, the r88 and the r168. The difference between these right off the bat is the number of channels and the protocol. These are all using the freestyle protocol um either d8 or d16. Your r84 is using d8. The r88 is also using d8. The r168 is d16. Hence this one six in there. This one has two way telemetry, so you can get v, bat readings and rssi onto your radio screen. Oh that’s, my gon na be my favorite right there, whereas the eight channel ones would have on screen display if you’re using a flight controller through one of the channels, it would display rsi on that and this one’s a little tiny one. Yes, so the reason i like the r84 right off the bat it’s, so slim look at this thing, it’s literally like a postage stamp with pins on it um. This is one thing i think: spectrum dropped the ball on years ago. They quit making end pin design receivers, which is a great slimline design for a plane. So when you have these profile foamies, you don’t want servo pins coming out vertically from the receiver to where it’s just a nasty mess of wires.
The r84 is an excellent choice. I think for your basic four channel, if you’re getting like the tech, one foamies um or the dw phones, anything scratch built yeah that all these um yeah pretty much any profile jobs. Flight test builds stuff like that um, if you’re looking to run a free sky based radio, jumper, radio, uh, radio, master, radio, et cetera and you’re looking to use the d8 protocol um or dc. If you have the ability to d8 protocol, i guess just to say um. This receiver is great for four channels of use: it’s very cheap it’s under ten dollars. It has two antennas for diversity: um, they’re, easy to reconnect. If you ever do cut one off bind one’s right there, you don’t have to worry about jumpers or anything like that. Um and it’s, just a good small form factor receiver. I was able to get receiver voltage feeding back but not really useful information, because, if you’re running a u back or something like that, um they’re pretty much the same voltage even when the battery’s dead. So realistically, rssi is about the only useful feature on that one. One thing other companies like horizon, or spectrum kind of missed the ball. In my opinion, they got rid of a lot of the end, pin designs um in the receivers for the longest time, which made really bulky, builds um. When the when the pins were coming out. You know this way of the res of the body.
Now you can lay it all in line and make just nice clean, setups, that’s gon na be a popular one. So i think this is great for your your four channel 3d foamies and basic beaters um. When you don’t need more than four channels, this is awesome, so it’s got a good range on it. The next one is the r88. The r88, instead of four channels, is now eight channels um. It has a hard plastic case instead of shrink tube um. The antennas are still replaceable with connectors. The bind button is covered in a little plastic shroud here uh. It supports eight channels and there is actually a ninth channel through the accessory port on the side that will support um rssi through that as well um. The night channel only does uh rssi it doesn’t it’s just for data out it doesn’t actually um work for another server. From what i understand, i have not tested it, but i’m pretty sure that’s what they said in the description on the site, all right um. My little thing right here i like the little antenna, the little rubber yeah they did also on the larger ones. They reinforced it. The little rubber boots here, uh nice thing about that is on when the plastic cases, when the antennas are pushed against them. For a long time, in a weird configuration and stuff like that, it tends to cut the uh the coax, cable and ends up damaging and fraying the antenna with these little rubber boots.
It kind of keeps it from doing that, so it can’t tear up the antenna. So that’s a really nice little design there one thing: we’ll notice, when we’re doing a little off camera stuff, we notice the stickers – yes, okay, so they did goof on this first batch here. Um. If you look at the pin outs here, you’ll see the little notches here. This is your signal row. So if you have a futaba, servo or so top of base servo with a little uh pin uh polarity plug on the side, then the signal goes to the top powers, the middle and grounds the bottom. They did do the stickers backwards on this um and i did check it. I powered it up and it was indeed backwards so guys literally either pull this off, throw it away or flip it around either way. I’M. Pretty sure this is just the first batch uh goop because they were trying to get these out so chances are. That will be corrected in later versions but um for the time being until then just double check and make sure you use the right polarity and it’s. Just a sticker, no big deal just the sticker yeah um, i don’t even know why they put on the side to be honest, yeah and the last, but definitely not least, okay. So this is. This is different. This one is d16 mode. D16 mode supports s, port, rssi output and v bat capability up to 18 volts.
So, depending on how you set it up, it will support battery voltage to the radio, so you’ll be able to get rss on your screen. Um and battery voltage wait a minute r says i am battery voltage yeah, so you’ll receive your voltage, not receiver. Voltage is actually moderate up to 18 volts, though so, really you’re limited realistically, but still, if you fly in the meteor or or anything like that, or this guy most park, fire foamies and stuff like that they’re going to be setting up if they’re for seller better Uh or less than great um for all the one receiver that does up to 4s view battery voltage, yeah be now it doesn’t you don’t, just plug it in you have to get a power tap off your battery lead, so you will need to put um the Hot lead going from your battery to the pin up here that four battery we’ll go over that in a later video. If you guys uh comment below. If you want us to do a video on how to set up the v bat telemetry, because it does require setting a little bit of calibration on the radio et cetera uh, we can go over that at a later time. I think loaded don’t tell me there’s more okay, so, unlike the r8, where it just has a generic fail, safe, where you push the buttons and sets it um, this one does have customizable fail safe, so you can uh, you know if you want it to kill, Throttle give right or like right, banking, rudder or something like that.
You can customize that as well, so there’s, two different versions of fail, safe um, because a lot of times the foamies, if they’re, upright they’ll, end up, you know yeah. Typically, i just set mine all neutral controls, throttle down and hit the fail safe button, regardless um, but this does have the option to customize your fail, safe as well on the receiver itself, the biggest benefit of the r16 over the r88 um. The fact that it has s port and s plus capability, so if you want, if you got a long long range system, that’s running a flight, controller, etc um and you don’t want all the mess of wires, you can run the s bus connection out from the Receiver to the flight controller and clean it up, and but you also have the amplified antennas you’ll see this version has the amplified antennas as well. So in theory, i think the range will actually be better on this one than the r88 as well. Um only way to do it is get in the air and test it, but for only a few bucks each guys go for it. You know these things are. I cannot believe how cheap these are in comparison to other receivers on the market. I’M. Just i’m kind of blown away because they have nice plastic cases, and this is if this was had a spectrum logo on it. It would be 60 bucks or more and more i mean all right, so you can see here on the rs 168 receiver.
You have receiver battery is actually your v bat um and then rssi is right there. Now you will have to calibrate this through the offset and i’ll show you guys real, quick through that i’m. Trying to do this upside down so bear with me. Um go here and you will go down to your when, after you discover new sensors stop discovery by the way um you’ll go to rx bat and then edit, and then the ratio will change. You’Ll change the ratio from default to whatever you need to calibrate, and you can see here on this guy, the battery we’re using i have a cell checker hooked up through, i got 5.48, so you can see here by adjusting the precision and the uh ratio. I was able to get pretty close to our actual battery voltage of 15.48. You see here and of course, this cell checker might be off a little bit too, but we got pretty close there and once you set those two, then you just back out of everything and just to show that this is working. This is a 4s pack and we can show up to 4s right, yeah it’s up to 18 volts max, so whether you, whatever type of battery you’re, doing don’t exceed 18 volts, you can damage the receiver right, so we’ll, stick with for us. You’Ll be good to go close it up all right. What will you, what do you think about these receivers? Uh, i’m, glad that they came out because, honestly, this kind of fills a blank that we’ve had for a while with not getting free skype products.
Just saying um but uh, basically, the r8 r84 um great little park zone or not park zone park, flyer plane, scratch built foaming et cetera. Four channel basic planes awesome fill in the blank right there, the r88 uh it’s cheaper, it’s, eight channels it does rssi. It gets the job done, it’s a nice hard case. So this is, i would say this more like your park, fire, probably sport, sport receiver, i guess you’d say you put in a dynam airplane, yeah yeah, but um. If you have the extra dollar or two well, this one, i think kind of takes the cake realistically, because if you’re gon na get the r88, this one will fit the bill too, unless you just don’t have d16 on your radio, which there are a few out There i think that only support d8, not but that’s, that’s, pretty old radio, probably um, but our the r168 has s. Port has v bat. It has s. Bus it’s got eight channels as well um, i think, and the amplified antennas unless you just don’t, want the amplified antennas because you’re building a like a slimline, build or something like that um then i think this is probably the receiver to go with. Overall. However, i do think they all have a place in the family of receivers for d16 or d8 guys thanks for watching and let us know if you want to see a range test with one of these.
They claim up to two kilometers, so that’s a long way. You have to walk well, i ain’t walking i’ll stand there.
