 Chad don't you have a dremel tool? I need a dremel. I think David has it Marvel I cannot find any of the dremels here. Didn't you you had one the other day, right? Yeah, David took it. Tyler, do you have one? I think David took it. David, I've been looking all over for the dremels Can I I need a dremel tool. Can I get that one? I'm using it. No, you have like everyone's dremel You took like five. Would you turn that off? You have like five dremels all of them Yes, you can't possibly using five dremel tools. Give me one of them You have built a quadcopter out of dremel tools and the first question I want to ask is why but then I mean you just I mean I think that's self-explanatory. Self-explanatory because it's awesome. I guess anything with a motor you could build a quadcopter out of Are these like particularly well-suited different quadcopters? Absolutely not So these are brushed motors in here They're huge like that size and they're much less powerful than our tiny little brushless ones They're this size like the cap of this so that's a challenge to get this brushed motor to be at its peak performance These are 30,000 rpm That's actually pretty close to the rpm that our quadcopter motors make. So I thought let's try it So I took a single dremel and just put a prop on it and let it go proof of concept I should probably tighten the prop down a little bit that's gonna work and it does fly I'm a little nervous about this thing This is armed up here. That's armed Staying up. It's flying. How is it Drew? It's oh man, it's pretty rough. I'm like a 80% trial just to keep it alive How are you gonna maintain line? You know orientation? Why do you keep it moving forward line of sight not too difficult when you bring into a hover that's up Oh, you got to sit it down gently if we can Good landing. That was full throttle at the end. Good landing. That battery is sagged out. We have it flew. It does fly That is an accurate statement. Flying at FPV is gonna be like riding. We got to overcharge the 3s. Oh, no No, see that's whole time. I've been saying why don't we run this on 4s? Why don't we overcharge the 3s and the problem is the motors might take it? But the speed controllers don't they go the ESC's are rated for 3s Is it rated for 3s or is it rated for a certain voltage? It's rated for a voltage. What's that voltage? It's I think we can overcharge it. What can we do to get a longer flight bigger battery? Well, then you just start adding weight. Yeah higher C battery So this is we have one high C Yeah, this is a China hobby line. This is the highest C rated 3s that we've got in fact This is the highest re-rated 3s made in the world today This is actually the last 3s battery anyone in the world makes 4s life success life Let's charge this by up and hope nothing happens to it. This is like the Constitution from that Nicholas Cage movie. That's what this battery is Who's the declaration? What's the performance differences between these Dremel motors and like let's just say a cricket motor? Oh nice The difference being that these are really big really heavy I'm very inefficient compared to a brushless motor of the size that we use There's a reason why Jamal Uses this in this kind of unit and that's because they're super cheap and this if this stalls out You don't have to stop it and try to find the AC. Exactly. You just need voltage in there. That's the problem for us though These are brushed ESEs So these are made for airplanes and they have a crazy amount of filtering Wow, that is slowing down Very slowly back in the day FM radios and you had jitter on that And you didn't want that in your motor so they're like I will just gonna throw a crap ton of filtering in there And that's gonna make the AC better Sure did on planes But the response time on these are so slow. Do you guys drill the arms out to fit the bottom of the Dremel? Yes, so these are See all one arms and I just made a bigger hole with a Dremel So everything that was needed to be drilled or anything was done with a Dremel Sure was Dremel didn't want to sponsor this episode because they thought this was irresponsible David I noticed that we're using the this three cell lipo to run. Yeah, we're not actually using the batteries in here So wait a minute. Oh, yeah, that's not the that's the battery bit. What is this? It's not a pretty deep printed parts. You may oh, that's the only right actually Chad made them So that's the crazy part not Actually went through like all the processes of making it look as factory as possible Cuz I thought this was the bottom of the room. Yeah, the reason why we did that is I tried to do it with the stock batteries But they're just so heavy and they're not made for this high current So you saved weight with taking the the factory batteries out of it, but what's the all-out weight right now? 2.2 kilos plus. It's a heavy pig. I got a question. They don't make prop adapters for Dremel tools How did you get the props attached? It's a standard Dremel mandrel, right? Yeah That's a call it from a plane and then this is the shaft Crazy see that sure that's using your brain people this right here And that is just a standard Dremel. So we can still put tools on this and cut things Like dude that looks like like it was made for this. Yeah downside is if you crash this this is gonna bend like cheese Oh, no, we can't this is we crash this it's gonna be a disaster We had to tighten up the The lug nuts Is that what that is? The mandrel. Today on Rotorite We're gonna learn the difference between a mandrel and a collet a collet is a thing that clamps down on the end of a Dremel and a mandrel is a kind of monkey Think about how much work the pioneers of FPV had to go through to get there This is probably about our janky. Yes, there's probably about right. We have it so good nowadays These are durable and reliable You were one of the pioneers of FPV was this pretty much what it was like every I didn't have a flight controller We're cooking we are cooking way faster than I would like to be going Does it Don't pass me Turn it left turn it left Got it. Oh my god My god, oh my god. Oh my god. Oh my god. Oh my god. Oh my god. Oh my god Oh my gosh, dude, it's so wobbly oh Poor dude, should I gap the V we got a gap to be. Oh My god, you're flying it Oh, you're so high I'm just ending oh down Now wait when you picked up speed it actually looked like it kind of stabilized a little it looked like it was flying It kind of did it kind of fell a little smoother once we got going Maybe there's something to aerodynamic about four pillars. Just plow. What are you gonna see the damage? How is it? I can't believe you can play it again. I can't believe we haven't broken an arm I don't know. I'm just gonna be fine. These are five mil arms. This HD one is just unstoppable We got some good shots yeah, and I'll put a little bit I do want to try to flip it just get it up and then just full roll Oh, it really took a tumble when I went down I was full throttle to save it when I'm through the V and then decrease throttle a little bit. No, no, no Can't do that. Well, I had to descend and so then it just started descending So I tried to catch it when do anything by the end. I was full throttle still going down. I'm like come on come on come on Come on tumble and it did a couple end over ends. Yeah shoot I think what David is saying is if you want to climb raise the throttle if you want to descend raise the throttle more I Think someone else should get to fly besides me though. He's gonna roll it Yeah, did you say roll it like go out in the field and go way up high? I'll do that your flight so you feel it out, but I think I think if you're gonna We're gonna lose light we're gonna lose light. He's gotta just go no just we can do it We can pull two flights. We can pull two flights. It'll be okay. Are you feeling I'm feeling nervous You got this He's flying it. It's just flying like it flies like it flies like a cinnabee How does it fly like a cinnabee like just like the just flies real slow Feel stable. Yeah. Hell yeah, you're just you're going dude. Wow Wow, you're just going it looks good in the air now try to take it backwards Dude, you gotta do something man. Do something take it backwards through one of the pavilions Did you film it at least? It looked like I was good, but the weight of it I was like it didn't explode explode No parts came off cool. So we just need to plug that in yeah plug that in and change some props and Do we have props we got everything? Okay? I won't fly again. I'm thinking we should throw for us on it. We're out of light We've done everything we could do. Let's go for us. Let's rip it. Let's see what kind of potential It's really got it's kind of irresponsible because the ratings of the ECs are 3s max So this might just plug in and go poof. Yes, of course. You're gonna flip it now. Okay, we're good David really wants to see the flip. Yep. So you may just go right to David's asking for the flip You may just go right to the flip Oh dude it flips perfect Freakin way That bottle flipping Fire I also smell that cell anything Little stinky As hell it was just like oh much area See was it a battery? Was it a dremel motor? It's coming from the center smells like it's an EC. It's just dead dead. Is the air unit dead? Everything's dead. Let me see if I got video now No, it's dead. The air nothing's powering up. I cannot believe we didn't break an arm I can't believe it bottle flipped from that hot that might be the highest bottle flip from a quad ever I have to say this was a pretty good success though I was way more successful than I thought it looked very well I mean it flew and I'm actually really impressed with how well Corey is able to pilot it because I was really struggling And when David brought up the idea of a flip. I just I was like, I don't think that's gonna be possible Really need pro pilots for this for sure Like I'm pretty good through the trees and everything I honestly I was I was hanging off a deal magic fingers It's that magic fingers. Thank you guys so much for watching this episode We hope you loved it if you got any ideas for more crazy stuff We should turn into quad cuptors. Let us know in the comments yours. Thanks today We've been to stall for making the impossible fly No one asked for Dremel drone here it is Oh, he's coming for it. Look at him. He's coming for it. He's doing what to do He's coming
