Short instructional video segment (Kenny Keller) describing the helicopter collective control. The speakers explain that the collective—operated with the left hand—changes the pitch of all rotor blades (three-bladed rotor) to increase lift (pull up) or decrease lift (push down) to climb or descend; small throttle adjustments at the collective end maintain proper RPM/operating range.
Alright, so here we go on to the next one. We did the pedals, talked about that. Now let's talk about the Click Collective is what makes the helicopter go up and down. Basically, it's in your left hand. When you raise the collective, it changes the pitch on all three of these blades. And the instrument is three bladed. And that's what makes you go up. When you want to go up, you pull the collective up, increases the pitch of the blades, increases the lift, and it goes up. You want to descend, you want to go down. Exact opposite. You just lower the collective. As you lower the collective, it collectively decreases the pitch on the blades and then you descend.
This control right here is what we call the collective. Move this seat belt out of the way. We have a lock right down here that keeps this in place during flight. This is relatively simple. When we want to go up, we raise the collective, we want to go down, we push down. This collective, as we've mentioned before, increases the pitch on all of the blades. As it increases the pitch, that increases lift. That's what makes you go up, you want to go down, you push it down, decreases the pitch and the helicopter descends. Here on the end, we have the throttle this way for throttle on, this way for throttle off. So we're raising and lowering this collective and we're also adjusting very slight, just very slight minute changes with the throttle to keep the RPM and the operating range.
