Where's the propellers?

So it has four rotors.

So in this picture you see that rotor four is spinning faster and rotor two is spinning slower.

Cockpit, propeller, engine.

And then finally, if you spin opposite pairs of rotors faster than the other pair, then the robot yaws about the vertical axis.

I never should've taken the freighter. Should've gone by clipper.

Yes, it must be a flying machine. It's got, um, propellers.

You're not powering the propeller, you're powering the wheels.

If you spin these rotors at the same speed, the robot hovers.

If this plane is imaginary, then so are those engines and so are those props.

So these are helicopters with four rotors and they're roughly a meter or so in scale and weigh several pounds.

If you increase the speed of each of these rotors, then the robot flies up, it accelerates up.

But if my theory is for the birds and those props are real, make sure you notify my wife.

And the other way around, if you increase the speed of rotor three and decrease the speed of rotor one, then the robot pitches forward.

Currently stationed in the main hangar at the airforce base are two Mi 24V helicopters without the blades for their main rotor and one functioning Mi 24P with blades (registration TU VMO).

And despite the aerodynamic interactions of these propeller blades, they're able to maintain stable flight.

That's nothing new that's a propeller clock that's the rims that you can buy for your car.

You forgot the paddle!

And they've already found that by being more intelligent about better propeller design, you can reduce that noise by 90 percent.

In a helicopter you feel and it's still a remarkable sensation you feel like you're being hauled up from above by a vibrating crane.

Raise oars!

Strike oars.

Strike oars!

Extend oars!

Right oars!

Weigh oars!

Paddle.

Paddle, that's it. I've got to send the paddle.

Paddles out.

Little Ricky out there on the lake without a paddle.

Ricky's paddle.

Ricky's paddle?

Be ready to raise oars.

Prepare to paddle.

He came for Ricky's paddle.

Man the oar banks. Hoist anchor.

If anybody is gonna take Ricky's paddle back I'm gonna take it back.

You forgot your paddle.

Ricky needs it.

I'm taking it to him.

How do you wrap a paddle, anyway?

People send paddles every day.

Go back to your oar, 4 1 .

We met with you during the sunset. You were cutting the gulf with oar.
