 Why I am at the driv and I'm joined by job boy vortex We are always flying these FPV freestyle mini quads But I want to do something a little bit different today because what you might not know vortex here before we flew the drones Was really into helichopters. Hello something just a little bit bigger. I'm excited about this one I have not flown this thing for like two years. So this is called a collective pitch collective chopper Helicopters that means it can fly upside down. It can fly upside right So what we're gonna do today is learn a little bit about how a collective pitch helicopter works And then what I want to do is get the best chase footage sounds really dangerous Well, we just have to not hit each other. That's true So Jeff won't you tell us a little bit about what a collective pitch 3d helicopter is and how it works So the frame of the helicopter is from a company called SAB and it's called the goblin 700 competition the motor is made by a company called scorpion speed controller is a castle creations 160 amp speed controller. I've got some RJX hobby servos MSH brain flight controller and for batteries China hobby line actually hooked us up with some brand new 6s 5,000 milliamp 70c Lipos and I'm actually gonna run these in series So that's gonna take us up to 48 volts on this guy Collective pitch helicopter works a little bit differently than what you're used to normally the throttle stick actually controls the throttle I found this as soon as you arm it the motors It's gonna spin the blades at a hundred percent And then the way you get lift is that you can actually see it can make pitch both ways So what you'll see is when you're in the center the blades have no pitch on them So it's just gonna spin you're not gonna have any lift one way or the other and then from center up That's your positive pitch. That's what's gonna make you go up center down It's gonna give you the reverse pitch So now you're gonna go down and what that enables you to do is go upside down But still have the lift to either sustain inverted flight or actually to climb up for your control to actually move it around That's a little different to and it's a little strange how that actually works So when you move your right stick, you're gonna be moving the swash plate That's what actually controls forward back left and right of the helicopter essentially whichever way that swash plate is tilted That's the direction the helicopter is going to fly and the way it does that every time this blade crosses over that path It's putting additional pitch on that blade in that direction just for that moment as it crosses this wash plate So instead of like a quad where it's going to speed up or slow down to of the motors It's actually gonna change of the pitch of the blade only in that direction that you're trying to go as you may notice This is a massive material here with this big head and these long blades So in order to keep the entire helicopter from spinning out of control the opposite way as this That's what the tail is doing making thrust going this way to counteract this from wanting to spin out of control You can also add pitch either way with the tail to just to make it spin that way or Reduce the pitch even more to make it spin back the other way the way that the flight controller on the helicopter works is different Instead of sending a signal out to a speed controller to speed up or slow down a motor They're actually connected to servos. It's going to give the servo a signal to counteract the movement So if I tilt the whole helicopter to the left the whole swash plate will try to stay level Same thing backward and forward if I push it forward It's gonna tell the servo in the back to drop down to try to keep that swash plate level a helicopter is a much more mechanical device It's not just all electronics. So there's a lot more Mechanical pieces going on you're flying two five thousand milliamp hour six cell batteries basically a giant 12 cell This is what I'm gonna be flying also by China Hobby line 1500 milliamp hour four cell this gives me about three minutes of flight time on my drones going all out at 60 miles an hour How much flight time do you get out of all this about three minutes? So that should tell you just how much more power is being made? All right, so let's take all this out to the field. We've got vortex gonna be piloting this giant helicopter I'm gonna be flying my mini quad. We're gonna try and get the best ever chase footage of a 3d collective pitch helicopter Cameraman if that thing is coming at me you'd tell me to duck and I will throw my I'm so scared to have my eyes covered And while that thing is going Did they always have a gyro no they didn't actually they used to have what's called a fly bar which was a weight They would just mechanically give it a gyroscopic effect. Oh, it's so informative Let's see what we captured here. Yes, I struggle more than I thought it's not easy This is the first run already. I'm I think that's pretty sweet, but it's just it's not close I'm just basically doing like an orbit. Oh, yeah, it's so free. I'm like I want to go close I want to go close and then you go Already this is kind of exciting actually But it seems like I'm only able to get kind of close to you when you're doing something predictable If I could be really close to you when you're cheese when you do one of those pierce lips or if we could start coordinating Yeah, that'd be cool if we could get someone like yeah, they call that a rainbow when you go like this Because actually this is better than I was expecting. I thought I totally flopped it But I think it could be that that's that's pretty sick We got to get you to loop around me right the other thing we struggled with out in the field was a Cameraman trying to keep up with it because it's really erratic So I don't think we got as much on ground footage But I talked to Chad and he seems to have an idea for some sort of like a rig that we can build we're gonna put together some rig with PVC pipe and these sites and hook up the camera and then that way Rather than the camera guy having to look at the screen on the camera and try to follow a little dot on a little LCD screen You can just point this this whole body rig So basically then you're gonna try and keep the helicopter in these sites and that'll make for good framing on the camera Exactly, exactly. I mean, it's not gonna be totally perfect, but it'll be enough where the helicopters always on the screen Yeah Yeah, that's looking good. So let's get back out there tomorrow I'm gonna fix my camera settings get rid of some of that grain try our new rig and hopefully put together Even more excellent montage. Sounds good. I'm excited So I'm just gonna try to keep it as close to this spot right here as I can That's one I'm gonna go for a really close one. That was close. Oh my heart is racing I'm about to get going into the circles. Are you going backwards and inverted? Yeah, okay. That's the trick. Oh, I lost you There it is. Okay Still pretty far Okay, I'm getting closer. There it is. Oh, yeah, this is it. We're getting there dude. We are getting there Hold on. I gotta change batteries I got there was one moment on the path. I was I held it Oh, it was like right there We got to do it in the slow-mo because the slow-mo all you need is is three seconds and it's like Thank you guys for joining us today We set out to get the best possible chase footage of a big 3d collective pitch helicopter I think we got some really epic shots. I think we got it all the batteries. I'm flying today We're provided by China Hobbyline. Thank you China Hobbyline for sponsoring this episode They make everything that you would possibly want if you're doing this FPV mini quad thing my favorite has to be 1500 high discharge they rated at 120 C, but they also have other options They gave me an 1800 milliamp hour battery, which is a little bit larger a little bit heavier So it may not fly as well as a 1500 or 1300 because the extra weight But it's gonna give you a little bit more flight time Which is really helpful when you're doing a shoot like this and if you need even more flight time or if you're doing something long range, they even have 1200 milliamp hour batteries and you flew 6s 5,070 C But I actually took two of them to fly for as long as you could fly off of that one little battery Just giant bricks when you're not flying you can get your beef cake on it literally weighs as much as the helicopter Batteries if you want to get stocked up on mini quad gear including some China Hobbyline batteries Make sure to visit store.rhodoriot.com link in the description So if you enjoyed this video make sure to subscribe hit that like button do all the things leave a comment There's a bell too if you want to get notified every time we upload one of these videos Yeah, you know you want us in your phone being like hey watch our videos.
