Today we are taking a look at the ls 38 by lsrc. It is a foldable 5g wi fi fpv 6k camera electronic image, stabilization, brushless, motor gps and optical flow sensor. Positioning rc quadcopter ready to fly so taking a closer look. It’S got the elbow style, folding arms very similar in design like the tmq visual drone. That was very popular some time ago. This one, however, has the 1503 brushless motor, so it should have better power. Therefore, better wind resistance: now the props are screwed on directly to the motors and they are the independent style blades. Without a center hub. We are given extra blades and the screws are coated with what looks like blue loctite notice, the single stripe on the b blades and the double stripe on the a blades. So if you need to swap them out, it’s easy to identify, which is which we’ve got landing gear affixed to the bottom at the ends of each of the arms and there are status led lights on the bottom of each of the arms as well. The main body is coated with a velvety like anti smudge finish, which is nice. We got the power push button on and off switch on the top of the canopy. We also have led lights in the front and the 6k camera. Now it will take 6k photos and 1080p videos and record them into the wi fi phone app and thus into the camera roll of the device used.
It does not have a built in dvr. Now the camera is hard mounted and it is remote tilt adjustable from zero to 90 degrees. On the bottom, we have the 720p resolution optical flow sensor, camera which shoots photos and videos at 1280 by 720p, the wi fi image distance is said to be one kilometers, and the control distance is also set to be one kilometers which i’ll find out in the Rear is the battery bay place. One finger on the bottom place, another one on the top and push the button and pull it right out. It should slide right out. It is a proprietary style battery and it is a 7.6 volt, 2000 milliamp size battery. It is set to be good for about 28 minutes of flight time charge it up utilizing the micro usb port and with the provided micro usb to usb cable, it will take roughly about three hours to charge slide it right back in push it in and it’ll Lock into place, the remote controller has flip out hand grips, but it does not have flip out antennas. The antenna is inside the housing and it is a dipole antenna. It would, however, take minimum efforts to make it an externally positioned antenna, but for this test we will leave it how it came out of the box. Now the built in battery is a nice size. Lithium ion 3.7 volt 550 milliamp battery set to be good for about one hour of run time.
Now the two position phone holder is spring loaded and it will fit a 5.5 inch phone, nice and snug on the top left. Shoulder is the remote tilt dial for the camera from 0 to 90 degrees on the right. Shoulder is the dedicated photo and the dedicated video buttons. There is no display screen of any sort, so the wi fi phone app will be the only source of visual display. We have the lock unlock button to arm and disarm the motors with a short press, long press, the button for gyro calibration. We have the headless mode button with a short press and with a long press it will initiate the compass calibration. We have the speed changing button with a short press speeds. One and two can be had long press to turn gps on or off. And finally, we have the smart return to home button press it and the quadcopter will fly back and land where it took off from autonomously. Both sticks to the bottom and out will also arm the motors and both sticks to the bottom and in will also disarm. The motors, as well as pressing the lock and unlock button, all right guys. So here we go with the test flight. We got the quadcopter ready to go. I got the battery fully charged and it is inserted a little gloomy day here in the high desert, but there’s not much breeze. So it’s a very nice day powering up the quad kind of soft, but the esc’s have sung their song and powering up the remote control automatically binds.
So, every time you want to fly one of these gps, quadcopters you’re gon na, have to calibrate the compass and to do that on this. One, you’re gon na have to long press the headless mode button. Okay, lights are blinking, so rotate it horizontally until a beep is heard and a beep has gone off, nose down and another beep is heard. Rotated clockwise and compass calibration is complete. Now gyro calibration long press, the lock and unlock button lights go flashing and they go solid and we are ready to go so to arm the motors. Both sticks to the bottom and out we’ll arm the motors and disarm. The motors both sticks at the bottom and in there you go, you can go ahead and fly it right now, uh. I believe we have acquired all of the necessary gps. Also, we got rear lights, blinking green, so i believe we are good to go, but first things first let’s go ahead and start the phone app i’m going to use my ipad so go into the settings, go into the wi fi and connect to the hygps wi Fi network oops – oh, that is the brightest since it’s a gloomy day very hard to see and we are connected now the app it is called the hfun pro app free downloadable app in the app store i’ve used this app before. So we are good to go all right, so let’s look down the line here.
Let me go ahead and start. The screen record. Okay screen is recording now there’s the settings you want to go in there and hit english and i’m just going to go directly into the start. Please take care of safety, keep a distance. Okay, all right. We got wi fi fpv and i can’t see very well because of all this cloud cover. Well, it looks pretty good and it’s responding rather pretty quickly here so let’s see if it takes a photo. Let me take a photo with the hard remote there you go. Would like to access your photos, you say: okay, so let’s go ahead and make our rounds and take some photos real, quick. There you go and one more so there we go. We have taken some photos and now we’re gon na start the video there you go. Video is on i’m gon na leave my ipad right here and come back to it in a little bit. So let’s go ahead and check this thing out all right, so you can unlock the motors by hitting the lock and unlock button and that’ll arm it. There’S! No one key to take off so you got to manually, take off there, you go throttle up and it is hovering very nice. In one spot, let’s see yours in place: oh yeah, y’all’s, pretty good let’s, bring it down, let’s see if we got gps position hold and yes, we do it got mad, it got angry and it went back to its position.
Whole spot very nice. Okay, i’m curious. I’M gon na try and turn off the gps, long pressing the gps on off button. The speed changing button. Okay, gps, is off so the rear lights are solid, so let’s see yeah. It looks like it’s just got optical flow sensor, but it does stop on a dime still yet go up in altitude a little bit Music and look it just kind of drifts off until the optical flow sensor is working nice. So you want to fly this thing. A little bit more sportier, you want to fly it in the non gps mode, which is right now and look at that. It’S still got good position. Hold man it’s almost like it’s got gps, okay, i’m, going to turn off or turn the gps on again there. You go, lights are blinking and we are in gps mode, we’re, going to start off in speed number one and let’s go and check this thing out so far it looks like it’s a pretty good flyer, nice and smooth hope. The video comes out good with the electronic image stabilization too bad. This thing, doesn’t have a gimbal at least a two axis gimbal. That would have helped it out a lot and the camera is kind of hard mounted. It is not soft mounted, so a soft mounting could have, you know greatly helped reduce vibrations as well, but it is hard mounted. So i do expect it to have some kind of vibration unless the electronic image stabilization is really good.
So hopefully it takes nice smooth, videos, okay, so that is speed number one and i am full pitching and full yawing, and that will be the full pitch and fool y’all turn radius, okay and it kind of plot those off all right. Speed number two: there you go a lot more pitch and it digs in after the turn, look at that digs down and it plateaus off. So you want to get going somewhere. Real quick, go in speed, number two, ah nice, so far so good. So there is only speed one and two, and this would be the full pitch and full yaw radius it’s, not that bad okay, let go, and it comes to a hover, very nice. All right so let’s go ahead and turn it around here and point it directly towards myself and let’s see. If i can do some camera tilting there, you go now: camera tilt and it’s very wobbly. Okay stay right. There tilting up the camera all the way up. Incrementally one at a time all right, y’all a little bit and there i am okay, all the way down to 90 degrees, so it’s looking directly at the ground, hey, not bad! Let me put it right above myself, kind of kind of drifts off a little bit and let me throttle up there. I am okay, camera tilt up. Okay, so let’s go ahead and check out the headless mode. There’S, a helicopter passing by yeah headless mode, push it forward and it is going to the northbound pull it, and it is coming back to the southbound of how you calibrated the gyros and i’m, putting it in a spin with a full yaw, spin and it’s still Going that way, and i push it it’ll still go that that way, that direction, because that is the northbound heading sideways and if i go to the right, it’ll go to the right as long as you’re facing the northbound of how you calibrated the front section.
The forward section of the quadcopter all right, so that is headless mode and it works perfectly so just like that i’m going to turn it off all right so far, so good! This thing is pretty nice behaving very well, so let’s go ahead and we basically checked out everything here. So let’s go ahead and land this thing there is no one key to land so i’m going to manually land it and it kind of slowed down by itself. A little bit and there you go, you can control this thing very precisely i’m, going to leave it right in the middle, so that’ll be our new home point, so arming the motors i’m going to manually arm it and take off all right. So now what we are going to do is we are going to check out the smart return home. I want to let go of the sticks and there you go i’m going to hit the return home button and it rises up right away. A couple of beeps can be heard and looks like about 20 meters comes backwards, the rear lights are flashing, still, nothing else is flashing and it is coming down eating its own prop wash there’s a tiny little breeze kicking in. It feels like about five miles an hour or so, but it is coming down straight. Look at that holding his position coming down and looks like it might hit the landing pad almost hit the landing pad right next to the landing pad that’s, pretty good, all right! Let’S go ahead and put it back in the center, and now i want to check out the fail, safe return home, so let’s go ahead and push it out.
Okay, but first what i want to check out is i’m going to hit the return home button, while it’s coming back from a smart return, home and retake control of it. Okay, so it’s rising up in altitude just like before going up to about, i don’t know: 20 30 meters, maybe like 25 meters, i’m gon na hit it and look at that. It comes to a stop and i am able to retake control of it. Okay, so that’s great smart return home button now remember these things: don’t have obstacle avoidance, so be careful when you hit the return home button, don’t hit trees and whatnot all right. So now what we are going to do is simulate the fail. Safe return home i’m. Going to go ahead and turn off the remote control, remote control is off let’s, see what happens. It should start rising pretty soon realizing it has disconnected nope. It is not coming back home guys. That means it is connected with the wi fi phone app and is it possible to control it yep? I got virtual sticks, and here i have control of the quadcopter with the wi fi phone app. So this is another one of those quadcopters that needs both of the wi fi phone app and the hard remote to be disconnected for it to perform the return to home the fail safe return home. So usually what will happen is if you’re flying and if you go out too far, the wi fi video will be disconnected before the hard remote control will be disconnected.
Hopefully that is the case. So the return to home will hopefully work in real life situation. The fail safe return home that is so i’m flying the thing with the phone app okay and it is doing pretty good, actually not bad huh, yeah, all right guys. So what i’m gon na do is i’m going to go ahead and turn on the remote control. Now and i’m still recording everything looks good i’m going to turn the remote control back on. Oh, look at that it’s rising up in altitude, all of a sudden what and it’s giving me a couple of beeps and what is going on here now: it’s performing the return of home. Oh my god kind of backwards, isn’t it okay i’m, not out of battery! Yet i don’t think yeah it’s coming down, so some kind of a signal got interrupted when i turn the remote control back on and it’s thinking that it has been disconnected or something and it’s doing the return home i’m. Not sure what kind of return to home that was fail, safe, return, home i’m, not sure guys so i’m gon na go ahead and restart see. I can still control the quadcopter okay. So there you go kind of funky there. It shouldn’t return home once you reconnect, but that is what happened here so i’m. Not a big fan of the both devices needs to be disconnected for it to do the fail safe, since it is a wi, fi, fpv type of quadcopter.
You still want wi fi video connected and as long as it disconnects with the remote control, it should come home that’s the way i would love to have this thing perform, but it is not. You need both the phone and the app or phone app and the remote control to be disconnected, looks like we’re in speed number one. Also, okay let’s see, if i can do some wi fi fpv here, speed number one and let’s see i’m gon na turn off. The virtual sticks, okay, pitching forward turning around okay coming this way – and there i am camera tilt angle – is a little bit too high. I think so i’m going to lower it down. Okay. Turning around there, i am yeah you can do fpv. With this thing. It looks pretty good. Okay, there, it goes kind of sideways. A little bit could be fighting the slight breeze that we have here. Turning around and coming towards me, there you go yeah, not bad, not bad! At all. The wi fi video is pretty decent. Okay, so it’s supposed to have one kilometer, wi fi video distance, so let’s go to speed. Number two and let’s see how far i can go in this field. Raise it up in altitude a little more and camera tilt angle up: okay, let’s push it all the way, let’s go and see how good the video feed is, and so far i got good video feed that little dirt road yeah.
That should be right about three to four hundred meters and i still got video it’s still bobbing and getting close to that road, or is that the road that is three to four hundred meters? No, that is not. That is the road in front of it. So it is continuing to go and what does the app tell me? Wow distance is 900 meters and i don’t think so. No that’s, not 900 meters, that’s the wrong data. There. Oh and look my battery level is 20. Oh very low i’m going to continue to push it here and i am getting video and looks like it is still going. I don’t see it anymore i’m, continuing to push it and it’s getting closer to the street and that’s the uh dirt road that dirt road is around 400 meters and looks like my video is starting to freeze and oh my god. The recording has stopped but i’m going to go ahead and pull it back and looks like it’s getting bigger, so it is coming back. So when will my video return, i should have stopped the video before i went and checked out the distance so that at least i have that saved it is still coming back. I can hear it i’m going to lower it down a little bit. Okay, it’s. Coming back looks like my video hasn’t caught: oh it’s, moving a little bit. Okay, quadcopter is back and i got video back sorry guys.
I’M gon na go ahead and restart the video there you go. Video has restarted so do yourself a favor, no matter what quadcopter you have you want to incrementally save the video just to make sure you got it if you got a nice little segment of flight and you got a choice, segment of video go ahead and stop The video, so you saved it and don’t. Let fate take its course of maybe not being able to save the video. So the app is telling me that i got very low battery life, but it is still going. It is not hitting the low voltage return home. Yet it’s supposed to have 28 minutes of flight time, so let’s go ahead and send it out this way and see how far i can go and it when it does hit the low voltage return to home. It should come back within 30 meters and looks like oh, it has just hit low voltage, return to home, rising up in altitude and it is coming back and even though i pitch forward – and it does not respond so it’s coming back and look at that. It has stopped and it’s holding its position, 30 meters away from myself, and i am able to retake control of it. So here we go. This is the first phase of low voltage return to home and there should be a geo, fencing and let’s see boom there. You go geo fencing.
I am unable to go beyond it one more time. This way boom there’s the geo fencing all right, so let’s check out how long of a geo fencing period this quadcopter has and just fly around here dip down. Okay, some reason it doesn’t want to come back this way there we go. I have orientation problems here: okay, guys just gon na fly right in front of myself back and forth, and i’m gon na go down to speed number one, so it doesn’t dip down as much so i can still fly around 30 meters is a little too small Of an area to have a geo fencing, but it is safe, it’s, a safety net uh system where, if you just happen to run out of battery, then at least you’re gon na land somewhere near your location and not somewhere, far away once it does run out Of battery and it has enough battery life to come back and there i am oop – i kind of skipped over myself here. Ah, the reason why is because it’s rising up in altitude, it has reached its second phase, so the critical low voltage return home and it is coming back home right eating some prop wash hey so far. This quadcopter is pretty decent. Everything is working pretty good. The only problem was the video stopped by itself, so let’s see how close it lands to the landing pad the home point and it will land right next to the landing pad.
So that is pretty good guys. So that is my review and test flight of the lsrc’s ls. Thank you. So much for tuning in and watching have a great day and we’ll see you again.
