HELICÓPTERO de CONTROLE REMOTO? Olha no que deu!

Today you will learn how to get a helicopter out of a tree. I know that this big drone, helicopter here, doesn't have much to do with the videos We usually do in Manual do Mundo, but we looked at this beauty on a Chinese website And fell in love and decided to invent an excuse to record a video. It came inside this styrofoam box that was all blown up, practically nothing comes with it… A fake remote, there's even a fake button here. That classic Chinese manual that says almost nothing, a few spare parts, a USB cable to charge the battery and that's it. Actually, No. There's also a little piece of plastic here that broke off somewhere, and I have no Idea where it came from. And there's one more detail, this drone here, if we can Call it a drone, doesn't have a camera. So why, after all, would we want this toy? Because if we compare it to most regular helicopters that we see flying in the sky, this one has nothing to do with it. It works very differently and that's why we liked it. First thing you'll notice is That it has two sets of rotor blades on top. One set rotates in one direction and Another set rotates in the other. And there begins a big difference from regular Helicopters that have only one set of blades on top. And the regular helicopter, When you turn on the engine, the rotor blades starts to rotate at the top, the tendency Is for the helicopter to rotate in the opposite direction, because there is a reaction There from the helicopter in relation to the blade. So, if there was nothing to Stop it, the blade would turn one way, and the helicopter would turn the other way. Stopped, stopped, stopped. This explanation is very complicated, it's hard to imagine The helicopter turning upside down… Manual do Mundo is better than that. Let's Build a helicopter. I made a quick helicopter drawing here to cut with the laser. I'm going to cut it in 6 mm MDF and I've already planned some fittings to be very quick to assemble. This helicopter won't fly, but it will float on water. Therefore, I also need to cut the pieces of Styrofoam that will serve as the hull Of my crazy helicopter boat. Electric part of the helicopter is quite simple. There's a motor on top, I'm going to have two AA batteries that power it. So, I have three volts feeding this motor, and I also need to put a switch on the side. Laser is so cool, right? I did this whole thing in an hour. Let's go to the pool. The idea here is to show you that the helicopter will try to rotate in the opposite Direction of the blade. So, the moment I turn it on and put it in the water, it will have to keep turning. The helicopter isn't moving.

I'm turning it on . This is exactly what would happen to a helicopter if it didn't have that little rotor At the back, that tiny blade on the tail. It is the one who will hold this movement. If it weren't for its, the helicopter Would be spinning in the air like crazy like what's happening with this one. In the air, maybe a little faster than what's happening here. Now that guy over there can continue the explanation on the blackboard, but don't Forget to give this helicopter a thumbs up here, okay? In this helicopter we bought Is different. It has another pair of blades that rotate in the opposite direction. So one movement cancels the other, and then it doesn't affect the helicopter at all. Let's open the front part so you can understand even more. It's open. Just look… Here at the front we will have a battery, it is a lithium battery similar to those old cell phone batteries. At the top, we have a little plate that controls everything, so there will be several Outputs for the lights, because it has some little LEDs that light up like the one at the front. But it will also have output for three different engines, the two main engines and the one at the tail. So, look how cool, we will have independent control of the propeller sets. You can Accelerate one and not accelerate the other and with that you will be able to turn The helicopter. There are two other cool things here… These blades are completely Free, in a very similar way to a filming drone, which unfortunately we don't have Here in Manual do Mundo anymore because we shot it down in the dam and, probably, This helicopter will have a similar end. This stiffening will happen because the tendency of these blades, when they pick up Speed, would be to escape on a tangent. As it is trapped, it does not escape, but Becomes rigid wanting to escape. The second cool thing is this counterweight that goes up here. You can see that this set of blades on top has a certain movement, so these little Weights will rotate along with the blades, and this mechanism helps to stabilize The helicopter so that it doesn't want to fall to one side, to fall to the other. I don't know about you, but since the thing is open like this here on the table, I Think it would be a good idea, actually a bad idea, but that's how we're going to do it, right? Turn this thing on to illustrate everything I said before we went out and tested this thing in the field.

So the first thing is to connect the battery down here. Now I will turn it on. Oops! I turned on the controller. It's better to read the manual first, right? Of course, all in Chinese… I can't understand anything at all. Oh, here it is in English. Oh my God. Everything flew. How awesome! Look at the blades turning in opposite directions. Fly now if you can! Go! You're strong! Look how cool, here I am giving the command just for it to go up. When I want to give it the command to go forward, it will turn on that rear blade To lift the tail and throw the helicopter forward. So, look, I'm going up, here's the button to go forward. It blew down here. When I want it to go backwards, it's the other way around. It reverses rotation and blows upwards. And it's so much stronger than I thought, it's about to take off with the wrench. Let's see this thing out there, shall we? Remote Control. Here it goes up and down, here it goes back and forth, here it goes around its own axis. It does it here. Here, we have a fine adjustment, right? A trim on this control, on this side this Button looks like it's more of a ghost… it doesn't control anything. And this Button here, we didn't find its function either. I mean, it's a remote control that, After all, has three buttons that work. Let's turn it on. Pena offered to do a Take before I use the helicopter, because he thinks I'm going to take it down on the first flight… My story with the remote control, check it out, I made that plane we made in Mauá, I crashed it on the first flight. The Rato Borrachudo robot I exploded in the first control… What do you think will Happen to this helicopter? It's obvious! Oops! Wow! Go up, huh? Except it's walking sideways, huh? Wow! This thing here has absolutely nothing to do with our late drone. The drone, you Could let go of the control and it would stay still in the air, correcting itself.

Not this here. In addition to flying crooked, it already lifts pulling to one side. If you let go, it goes away like soap on top of a granite sink. Man, it spins alone too much… And now you find out why it has a loose blades. Because then it can fall to the ground, Hit the blades somewhere that doesn't damage it, right? Because it's already taken Three falls here… Look there, it goes backwards, man! Stabilized! Hey! It looks like it's alive. Now I'm going to drop it and try to recover in the middle. That was fun, huh? Now I liked it. We have to leave it up there, close to the ground, it doesn't fly well. It's not going up anymore… I think its battery is low already. 3.06. Pena said that it cannot go below 3.2, that is, the battery is already in reserve. 25 minutes and it didn't load even half. I think it's time to fly, huh? The challenge Now is to make it pass through here. If it goes wrong, it already slides like a skateboard. Yeah, guys… The toy is fun, but the battery can't handle anything, right? I wanted to go down there… With a little more five minutes of training, I could do it. But it would take another three hours to let it charge. So that's it for today. Now go, now go! Go Go go go. That! Still curled the tail, but it was! We got a new drone, so now let's send up the helicopter being spied on by our own drone. Yeah, it turn on by itself.   Just because there was water doesn't it work?
