Collective (Pitch) Servo Initial Setup
In this section we need to make sure the blades are moving in the proper direction. We'll play around with the throttle/collective stick, which is the left control stick on your radio.
Step # Eight - Move the throttle/collective joystick from half/center to its bottom position.
Observe the rotor blade holders, they should tip up... this means "negative pitch" on the main rotor blades. Negative pitch will make your RC helicopter come down.
Next, move the throttle/collective to the top position.
Notice how the blades holder points down...This means "positive pitch" on the main rotor blades. Positive pitch will make your RC helicopter go up.
Note: If the direction is wrong, reverse the pitch channel. (Channel 6).

Step # Nine - At half throttle/collective stick position, the linkage rod for the pitch should be around a 90 degree angle to the servo horn. If not, rotate the servo horn (plastic star circle) and re-check.
