 8s here we go. You guys got video we got video see this happen. Oh, that's bad. That is fast. That is fast That's so fast. Oh The whole thing is stupid this whole idea flying 8s. Oh, I agree. Why is the boy who still flies for us? Building it 8s quadcopter. I thought lower-voltage. Why don't you fly to us because I don't see a benefit of success in four So maybe if I just maybe maybe If you're newer to picking out a battery you may wonder why would you want four s six s eight s The difference is when you go higher in cell count you're going up in voltage So if you assume you're making the same amount of power at a higher voltage the result is you're drawing less amperage The the equation is power equals voltage times amp draw So you could have two quads with the same performance at different voltages and the difference is the amp and actually having Lower amperage is is better It's actually it's less wear on the wires and then end the windings and all that stuff Let's heat build up, right? It's just the only question is can the Components on the electronics actually handle that higher voltage They need to have the right voltage regulators and diodes and That's yeah, so I so the flight controller I couldn't find one that actually supports a desk so I have to run off a 12 volt back So the 12 volt back in the back is powering the flight controller as well as the avatar VTX in the back. So we currently we couldn't figure out how to get OSD in there But there's what do you see you got in here, buddy? So I got the T motor f60 amp and funnily enough. It's 20 by 20. That's the only A-desk. I can find it just looks so weird. Here's the thing though I mean like you got higher volts, but like 30 volts as long as the FETs can take the high voltage I mean so what motors are we working with? So the KV on these are prototype T motor. They're two to a seven 1500 KV so I didn't do the math, but it should be matched RPMs ish to what we normally fly ish ish for reference a 4s 2450 KV combo is equivalent to a 6s 1666 okay something like that in my experience when you fly a 4s 2400 versus the 6s 1660 success seems faster. Yeah, it just does when everybody nobody really matches KV Because when people go to 6s they fly 1700 and 1900 KV. Yes, and then I'm even though you're getting more power more RPM So that means but somehow it all works out. Okay defined KV the KV of a brushless motor means that the RPM The motor will make is the voltage applied times the KV So if you have one volt applied to a 2400 KV motor, it'll make 2400 RPM 2400 is kind of one of those standard things my signature motor is meant to be used on 4s And it's 2650 which is kind of like a little little turbo little turbocharger for your 4-cell Well, I'm saying if you take that 2650 and cut it in half. That's still only about 1300 you said 1500 No, no, no, no hang on hang on That's the equivalent of a 3000 KV 4s. That's like I would say that's that's too much. That's too much You're gonna kill the bad. I'd say we're probably gonna smoke a motor But this is what T motors recommended is what they sent me like you want a desk is what we got There's a period and where all the racers right before champs 2022 where they're all like ate it ate it And I knew they were testing a bunch of secret ate us stuff But never caught caught wind in the in the freestyle community. So if this is good, I might be switching here We got you guys got video video Oh, that's bad that is fast that is fast That's so fast. Oh my right right there's bad. Oh, yeah Maybe this is too small of an area for an 8s. No, that's why we're letting bubby play so fast. Oh The mother rates are a whack, but you know, I mean It's weird it it feels like a race quad when I give full throttle You know, I don't have much experience with a lightweight success freestyle drones This is not a lightweight build though, and it looks like it's flying like a lightweight Didn't wait out. I'll put the text on the screen right there. That's how much it weighs But it's up there. It's probably like seven. Yeah, I got a full set to go for that You got a 10 on there. If it's under 800. I'll be surprised. There probably is 800 So I mean this is a heavy Quad and it looks to me like it's really buggy in it's flying like a lightweight quad Batteries heavier right up the bat. I mean, whoa I know what we got to know is how does it pull out a dog right if we need a big dog into the tree There's a canopy right big dog Right there. There's your canopy right there Oh my god, you're so commit buddy. Just commit. There's your can be left. Let's commit. Come in for that It's dude, I like this power It's handling all of your torture who tuned this it is I actually I took the tune and had to lower it because for some reason higher voltage with my volt when my Pids were a little bit higher on stock. It would freak out This is doc beta plate. This is doc, but lower. Yeah, look how much oh my god Oh, sorry. He kept going up so long after he cut. Where's the hole? We don't know He doesn't know either. It's fine. It hit a tree. Anyways, no dude that catch dude That's not that's I I've flown six. That's what I've flown Alex's lightweight success squad. This was better You think that's more power, you know, you know like Bartle said blind test, but I pretty I'm very Strongly in my gut. Yeah, that it was true. I do was just like having trouble speaking right now. Yeah Quad but that was a lot of fun. Who wants to play next? This is exactly what people like about success It's just more so yeah, it's like success, but 30% better It feels like more because going up from my 2650 to 3000 is only what an increase of 350 KV I I don't think it's that big of a difference. This seems like sounds and feels to me like it's 4,000 KV or something. That's just I don't know how you're not it's sagging it out. It's crazy What should I do? Should I go slow? Oh, no, you would do the do the barbell thing. I don't know Oh Wow interesting, what are you doing? The pit controller is just struggling. Yeah. Oh Rates rates rates. Yep. There's a little bit of an elbow in there. I give a full flip of throttle Oh, I see I'm just how much when you cut out. You're still traveling up for so long Yeah, I see I'm just toning it down. I'm looking at your throttle. You're like 15 under what you need is more Throttle more throttle. I got to lean into it a little hang on. Here we go From the screen here, this looks like it looks like a tune man. It's just some random stuff It's not great and I want to actually tune it and Wow, nice nice so responsive Nice save nice save Had that pullout power I really wish I could open it up somewhere Are you feeling a bag at all yet? I don't know No, no, and that is something that you know, I will concede is better about success versus for us is that the battery performance stays more consistent There's less sag again lower after oh, wow, so theoretically with eight cell Even less sag. I tried to catch it at the very last bit it Ah Less turtle mode Even turtle was an 8s All right, Bartels here under the canopy Rubik's under the canopy Rubik's The front flip. Oh very nice. I just got the flow Nasty Bartels Feels good. Yeah, I want to fly it more That was nice. I forgot you guys are watching. I was just around I forgot you guys are watching and I should be like trying to impress you. No, I mean, I am impressed Ripping a lot of these power loop gaps When you try to feel it, yeah, oh I was just trying to feel it out. I was like I got to do anything impressive That thing's 800 grams, then I'm I'm downright impressed So I think it's heavier. That's what it ought to be. It's got a bigger battery Heavier frame bigger. It's got an 11 and 7 8. Oh that does feel chunky Okay, close your eyes. Close your eyes. Hold out two hands. Which of these is heavier? I mean this this one's what are you pushing down on this? Are you not? No, this one is significantly heavier It's I legitimately thought you're pushing. I feel like this is more responsive than this I'm not good. Maybe this one's heavier. That's how you close your eyes This one all day. Yeah, it's definitely heavy. I think it's more responsive. That's fast And also, I guess these are very responsive props. I don't make a difference, but what prop is it HQ J40s? So twice so funny 29.9 or 20 30 volts is basically like storage so weird I might be interested in Seeing a form factor friendly way of using two smaller 4s batteries rather than this one brick of an 8-cell battery because it's like a collective pitch helicopter Pilots they routinely fly 12 s on their big birds, but they don't have a 12 s batteries They're using two 6 cell batteries So feel like we could do the same thing use two 4-cell batteries I mean just look at this thing and one of the things I don't like is that in a crash You'd be more likely to eject But you were pointing out if you lose one of those cells whole thing just goes in the trash Compared to a 4-cell battery in theory you're twice as likely to have a cell go bad. All right, John sir We're saving Drew for last as we You're gonna love it. It was great. All right, here we go Hey desk Okay, it sounds awesome. I like the power. Oh, yeah, pull out pull out is much better Yeah, like when I pulled out of the dive, I Definitely had I didn't have to give it anywhere near as much throttle as I do with my success Oh That's so sick That is awesome. Yeah, that's great. That's I like that. I like the power. I like the power Maybe I'll switch to a death. I don't know. I'm worried about the fires more than anything with me Sean Let's go. I'm just kind of worried about the fires. I Primiturally switched to 6s too soon Back in the day when the technology wasn't ready for it. Yeah, and caught a lot of stuff on fire Yeah Let's take this quad to a race and batch drop it for a weekend Right see if the ESC survives before we draw any final conclusions about ready We are to switch to 6 to 8s the rotor ride house builds are going straight before us into 8s, right right now. Yeah Whoa, what was that I think I caught a piece of mom that was the rates are low wonky and every now and then it will do a little bit Which oh, okay. Oh exciting It feels good though. No, I mean, I feel like I got the power is great It's so great. Like I never feel like I'm lacking I Never feel like I'm lacking in power which is awesome even with my 6s every now and then I wish I just a little bit more pull-out power What tree oh boy the highest tree stamp stamp, okay? I had to crash in the highest tree here But yeah, that's what I immediately noticed is that I have Infinite power it feels like I like it a lot. I like it so much I'm definitely building an a squad even if I don't even yeah, even if I don't switch to it I'm definitely building one because this is fun Tree there's a tree. There's another tree. Oh, okay. This arm. There you go. All right. I like that a lot. Yeah I was a lot. Yeah, yeah, I'm a I don't know. I'm kind of power hungry. Yeah, that really fit the bill for me I'm psyched about that. I want to do an 8s quad Okay, send it look great Yeah, I mean for just kind of flowing around I don't really feel any difference this feels Normal, which is a good thing. I look at oh my god. I'm not even trying look at his throttle. It's like 15 20 I mean if I oh my I can't even hit full throttle Not down here. It's up down here. I'm just gonna give it a blip. Oh, yeah. Whoa. Whoa It's like a little turbo. I love it. I do love it You're still going up. I know No problem Oh, yeah, I mean such power. Holy crap. So I mean like but look it's not like I can't be precise with it We're just kind of cruise around. This is fine for someone with less throttle control and precision than you They would probably find this harder to control. You're like barely touching 50% Except when you punch. Yeah, like If you can fly with half the throttle resolution, I got Kakariti Something's upset Kakariti with that inverted joss pin. Oh Come on. Why can't I'm at it 20 degree camera? It has there it is. It's fun. It is just a lot It's an exercise in throttle control because as soon as you mentioned about what you're right Everything I'm doing is below 50% throttle Everything unless I really want to oh really want to go for it. Oh god. It's Quick Try to get punchy try to get punchy Yeah, baby, I want my inverted inverted joss pin power loop thing Not there. Oh, why can't I pull out of it? It's cuz I suck. That's what it is I held it for like 10 seconds Coming down Nothing no big deal. No big deal. That's like that. I look pretty good Yeah, I didn't see any trough watch or anything. Oh, oh man No, oh, I'm sorry guys. I'm sorry. What this battery is good. Oh, no I don't get it. Go get it quick. Go get it quick. It held on it held on to the bitter end Maybe we can if it felt great until all of a sudden nothing just nothing That's the bad part about going up in cells Okay, I just flew for any response a lot of time I was just having so much fun and it there was no Indicator in terms of feeling that the battery is getting low. I mean I died for the mood I got the power. I was zooming and all of a sudden I'm like, oh, no, it's over and it just I couldn't even fly The more cells you have I think the more likely you already get surprised by a cell dropping out And the reason is that as soon as one cell goes below 3.0 volts Then it sags to zero So you suddenly get this three-volt drop right and then the whole thing is just done gotcha with a four-cell battery I can really feel throughout my pack how the voltage is going down I mean, and I'm used to it I can just kind of acclimate to it six cell I feel like you can sort of feel it coming on and with this I had absolutely no worry at all Ada's drone was a lot of fun. It's the first time I've ever Slightly considered I'm going to this I'm building at least one quad yeah and trying it out because that was a lot of fun And I got to have one to play with a little bit skeptical So I'm gonna try it with one quad and see what happens Yeah, I think there's downsides that this video hasn't maybe touched on as much as somebody who had to live with it That's a $40 battery. Yep. You talked about how it's easy to kill it's easier to kill batteries more cells We still don't really know there's only a few 8s ESC's that are suitable for five inch quads and They're pretty expensive and we don't know that they're not gonna blow up as soon as you start smashing them and bashing them People will say this isn't a fair test because we're at higher rpm and higher effective kv Just like when you went from 4s to 6s and you started using 1900 kv motors and somehow everything was fine, right? But you would never run a 4s battery with that high of a kv motor. We seem to have the same thing going on here The motors are coming down cold the ESC is coming down cold We have the theoretical equivalent of 3000 kv on 4s, which you would just not actually not on 5 inch You would have that's like a rear a 4-inch problem. Your motors would be so hot So I mean I don't know where the breakdown is between what the math is on paper and what's happening in reality But what's happening is this thing is a rocket and it's awesome. Yeah, it flies great It's not even tuned the way I fly the type of things that I think are visually appealing the types of tricks So I want to do I found that I was barely ever going past half throttle So that tells me I can be at half the voltage, which is right where I'm at with 4s I'm fine with it. I mean I mean I'm never using full throttle and with 4s Yeah, I'm using the full throttle range every now and then do I wish I had a little bit more power? Sure, but I also just think I could plan better, you know pull out sooner fly better I don't ever feel like I'm limited by my meager 4s power I could see maybe some day I might want to play more with five or six cell, but this is just overkill That being said I had an absolute blast. It was super fun to try more power John wants to drive around the parking lot at all times. Yes For somebody with a really poppy dynamic style where they're constantly punching up into the 75% plus Or for somebody I mean, I don't know why as a racer you wouldn't be thinking about this Maybe they also think they have enough power some racers run throttle caps Right now. Yeah, the real-world trade-offs of actually living this like you said a more expensive battery the fact that you have to have this Giant capacitor You fly this big but pass under daily 1,000 micro farat 35 volt. Yeah, that's a 35 volt. Yeah, not a 50 I couldn't couldn't find 50s. Wow. Well, you're definitely you have no headroom on that Yeah, that's great. If you have the money to build one and you think it might be fun. It's fun. It's fun I liked being able to pull out of any dive anytime without any questions I guess I just like the power I kind of now I'm kind of thinking maybe I'm kind of your side We're like for my actual freestyle flow, right? Maybe we don't need it, but it's gonna change your flow Yeah, you're gonna have a different flow. Do you need a track-prepped Corvette for public Rotel now? Is it kind of fun?
