Lama v4

[firebladeash]

Hi I have a Lama V4 chopper and it's a great starter pack to get a person into flying.What is the diffrence between the Lama and the cp and I think it's called the cpx.
Thanks.

The Llama and the Eflte Blade CX are comparable coaxial helis, meaning they have two rotors spinning in opposite directions to counteract each other's centrifugal force. This is what makes them so much easier to fly. The pitch - angle of the blades that gives them lift - is fixed and non-variable, you only get increased lift by increasing rotor RPM.

fixed pitch helis have the same type of blades as a CX/Llama, but with only one rotor and a tail motor to counteract the centrifugal force of the single spinning rotor.

The Blade CP/CP Pro and Esky CP2 are comparable collective pitch helis. This means they have
- a single rotor with a tail rotor and gyro to counteract the centrifugal force of the spinning rotor.
- collective pitch (layman's terms) means the amount of lift applied to the heli is a combination of the headspeed (rotor RPM) and the angle of the blades. As the throttle increases, so does the pitch angle of the blades.

- CP helis also have what is called "idle up" or "3D" mode. When you go into idle up mode, the headspeed remains constant - the RPM does not change when you move the stick. Only the pitch changes. So with the throttle in the 50% "middle" position, the blades are completely flat, with no pitch at all. When you move the stick UP - away from you - more pitch is applied which provides lift.

Where idle up mode gets interesting is when you move the stick DOWN - towards you. Now the blades go into "negative pitch." If the heli is upright, look at it as though this is what holds the heli on the ground (which it does!) But if you can manage to somehow get the heli flipped upside-down when you are flying guess what - this is what allows you to fly inverted - negative pitch.

CP helis are far more difficult to fly and don't have the stability of your Llama. It's very much like holding a piece of glass by the corners with a steel ball in the center and walking around the room, keeping the ball in the center of the glass. This is actually a very good heli exercise - if the ball rolls off the glass, you crashed. :D
