Rekon 3 1S Analogue Lion Long Range
. This is another collaboration between hlrc and dave cfpv. It is an ultralight, long range, 1s, 3 inch quadcopter with an analog setup. The gimmick bean that you can clip in an 18650 single cell lion directly into it and get a quoted 15 minute flight time. The majority of the frame is tpu 3d printed with some carbon fiber arms and the motors are hlrc’s own 11600 kv. The props are a jewel blade and they are a push on prop now the battery just clips in and it clips in really tightly. Of course, you have to get the polarity right. Otherwise, bad things will happen if you don’t, i think it needs a battery strap, because in a crash i can see that battery flying out the camera is the cadx, and this is the tbs crossfire version, but it does come in different receiver options. This is the 3018 dual blade propeller, which just pushes on we’ve got some screws in the package, and this is a diagram showing you the polarity. If you put it in the other way around, then there is going to be smoke. It’S a downside of this setup. We’Ve got some cards in here as well. I have been informed that the diagram with the prop direction on it is incorrect, so this diagram shows it having a props in configuration but it’s. Actually, a props out configuration the flight controller is an all in one, so it is a 5 amp bl heli s esc and an f4 flight controller it’s come flash with beta flight.
Of course, we’ve got this manual here, showing the setup. The vtx is a 350 milliwatt vtx, so not the most powerful. They say that you can get a few kilometers out of it, but you’re gon na have to make sure that you’ve got a good antenna set up for that. You see all of the specs there of the all in one board. Let’S take a look. How much this guy weighs, i think they say: 65 grams without a receiver, but i’ve got the immortal t and the crossfire nano here, so that’s, 67.2 grams, very lightweight and then with the vtc6 lion, that’s a 110 grams, a very lightweight setup. Indeed, alrighty let’s go for an fbv flight. With this guy we have got a nice on screen display here, it’s a sunny day, but unfortunately it’s a very windy day straight away. I am seeing some interference from the electrical system, so not a lot that you can do about that. Just taking a look here at the throttle position, we’re about 45 percent and pulling about 13 amps, you can see there. We’Ve got the voltage there of the lion. Uh 3.5 volts. This is a downside of having a single cell, it does a roll uh but it’s a little bit wobbly. I have to say i think the tune could be refined a little bit. It feels like the pids are are slightly out. You see that i’ve got the max power here at 350 milliwatts.
We have got the fly min on there currently at one minute in got the link quality up there on the screen. It’S really struggling in the wind here link quality at 99, but i feel like when i go around these trees. I am getting some break up. I can’t say i’m too impressed with the antenna on the vtx it’s sort of just loose and if you have it pointing up, then it’s going to get caught in the props. If you have it pointing down, then it’s going to be difficult to take off, but it’s a fairly clean feed for fpv. You guys are gon na have to. Let me know in the comments whether you think this is more of a gimmicky thing or, if it’s, something that you would actually buy. You know it’s it’s flying nicely here: you’re not going to be able to do crazy, acro with it. It is purely just for long range. If you give it any amount of throttle, then it’s not going to have a huge amount of power. It is literally for doing what i’m doing here, and that is, you know, just keeping the throttle in a similar position. You know 42 to 45 and then just flying it long range. Of course we don’t have gps here, so we can’t rely on that if we get a fail, safe or if you know, for whatever reason the video cuts out. So you have to be mindful of that and, like i say, you’re gon na want to have a decent antenna set up.
But you know this is flying nicely here, actually it’s a very windy day around about 16 to 20 mile per hour. So you know i’m not going to get the best out of it in terms of flight time today, but hopefully it should show you what it’s capable of now. One thing that i’m a little bit worried about is the fact that all of these components here are relying on a single cell. Now, with a lion, you can take the voltage down way more than you can a lipo, but a lot of these components here they aren’t used to running below 3.3 volts and, of course, this lion here will go down to 2.5. If you want so one thing, i’m concerned about is whether the components on board can handle below three volts. Basically, uh we’ve got andy here, he’s flying as collider. This is gon na, be a bit of a boring flight and that’s kind of why i say you know you can’t put another battery on this. You are stuck with a lion, so it is basically just a cruiser. So would you buy? This is what i’m asking of you guys there’ll, be a link in the description of this guy. I think it’s been up for pre order for quite some time now. So i think you know people who are interested in this guy. They may have already ordered it. Uh but from my perspective you know i’m having a good time here.
I’M just cruising around again: i’ve had to go up on the throttle a little bit as the uh. The voltage comes down, but it is a steady 3.4 volts here, we’re now, four and a half minutes in it does look like we are going to get a long flight time out of it. As for the tune, uh it’s wobbling about here, i feel like the tune could be a little bit better. I just left the tune that it came with out of the box uh. It definitely feels like. I think it feels like the p value is a little bit too high it’s sort of shaking itself about a little bit uh, getting a little bit of break up as well i’m using the rapid fire module and my fat shark goggles here. I’Ve give it a little bit of camera angle because of the wind i can. I can hear andy fleiner’s power to collide around me but uh. I can’t see him i’m looking around see if i can see him i’m, not really noticing any jello through the camera, which is a good thing, because it’s mounted in tpu. In fact, the whole frame is tpu a little bit concerned about the arms on this quadcopter. They are really thin. I think you know we’ve got the the weight of the the battery on there, which is you know, the main weight of the model, and i i think, if um i had a crash with this guy i’m, not too sure about those arms.
They are replaceable, though, actually they’re just on a single screw, so a 1.5 millimeter hex screw so hopefully you’ll be able to get replacement arms for this um because i don’t think that it’s going to be durable at all uh. So let’s take a look here. We’Re at a six minute flight time at a 3.2 volts, you know the uh. The video feed is looking pretty clear. I don’t feel confident going outside of this field with it to do. You know a proper range test uh just because of the wind uh let’s see uh the throttle 42 yeah it’s holding its throttle. Well, i mean i’d, say i’d like to see a more powerful vtx, but man, if you know just maybe a couple of years ago, if you’d have said, oh, you can have a one s quadcopter that flies for over six minutes. Potentially 15 minutes it’s using one of these lion batteries. I wouldn’t believe you at all so um. You know it is easy to criticize this thing but uh. When you look back even just a year ago, you would say nah, that’s, that’s that’s, not a thing, but it is so so there you go okay, so as the voltage is dropping now 3.2 volts actually doing very well. I did expect more voltage sag than this. Now hlrc have told me that the components here they can deal with 2.6 to 2.8 volts but i’m, not so sure about that we’ll we’ll have to try it i’m trying to outfly andy’s glider here uh.
I think i might do it, although you know he can find a thermal and come off the power. You know, i’ve got the uh the camera angle a little bit too high here, uh for this direction. I’M, just gon na hover a little bit here. Getting a little bit of a wobble now on this guy, so the prop it’s, a gem fan prop actually with a 1.5 millimeter shaft, not seeing any problems here with the prop flying off or anything like that. The codex and actually 1000 tv line, it’s a cmos camera let’s, say not getting any jello, which is a surprise with the the dual blade prop we’re coming up to eight and a half minutes now, it’s, pretty incredible. Really. I think they say that the wheelbase of this guy is a 140 millimeters. You can’t really put a bigger prop on this guy. Just a three inch prop doesn’t look like a three inch model, because it looks like a stick insect. You know because it is such a tiny thing yeah, so a 3 000 milliamp hour battery we have got the current draw, but not the uh. The total current draw that might have been helpful on here. The vtx is switchable. You know it does 25 milliwatt, 100 milliwatt, 200 milliwatt. But really you know if you’re using crossfire and long range, then you want to stick to 350 milliwatt now this was sort of like a prototype sent to me.
So i put my own rates in there, but the beta flight setup was pretty good. I think if i recall it had motor stop on so i think i just turned that off, but uh the rest of it was a pretty good setup, which you would expect, because you know they’ve collaborated here with dave cfpv, so he will have put all of His setup on here, that is something is great about any sort of collaboration. Oh, we are getting the timer flashing at 10 minutes and we are just hovering at 3 volts. So you know what i think as a sort of safe flight. I would stick to 10 minutes and land it here, because these components, you know they are not used to running below 3 volts, but it seems like it is doing it so far. I think i’m just going to fly it until it won’t fly anymore, whether that is because we don’t have enough power or the fact that you know it’s getting a brown out now hlrc did say sort of like they warned me that you know when it sort Of gets below uh three volts then make sure that you know your your throttle is pretty low uh. You know to make sure that nothing browns out, but i i’m not sure that’s possible here. I’M now at 54 you know 60 throttle everything is flashing here and uh it’s not like. I could dip the throttle to recover from a brown out, because i i am giving it as much throttle as possible to stay in the air but any less, and it would kind of fall out of the sky.
So that’s uh, you know 11 12 minutes. It is still going i’m sorry it’s a bit of a boring flight but uh. You know it’s one of those things isn’t it. You know you either have a crazy, powerful quadcopter that flies for four minutes and it’s, like you know, flying a roller coaster or you know we have these cruisers, but uh. You can’t, really do acro with them or it’s, starting to feel a little bit heavy. Now. So uh yeah around about 60 throttle on 2.9 volts. This is this is where i’m uh feeling a little bit scared. Honestly, they say 15 minutes. Oh, i don’t think this is going to do 15 minutes uh the lockout on these things, 2.5 volts per cell 2.8. Oh man, 12 minutes yeah there’s a little bit of a win, but if, if i was paying money for this thing, i i don’t think i’d want to push it. Oh, oh look at that. Oh no, oh the vtx locked up come down on the throttle. Oh right, okay: well, there you go, it’s died, let’s, uh, let’s, go and check out what the damage is. Well, unfortunately, it is not great news the arm has snapped and the battery actually flung out. So i do think a battery strap would be useful for this. Guy something that is a little bit daunting when putting one of these eight and 650 batteries in there is that once it’s in there you know the quadcopter is live.
The vtx is live and it’s not easy to get out by hand, but when you have a crash then it seems to fly out now. You can get replacement arms, so that’s a good thing, but this thing is definitely not durable in a crash and there you go. That is my review of the hlrc recon three i’ll put a link in the video description, as well as a pinned comment.
