STEP 9-3 FINAL SERVO AND RADIO SETUP
7.Collective Pitch Setup.
A Pitch Gauge will be required for this operation
The total pitch range of the is approximately 30 degrees depending the rotor head settings you have done. With a maximum and
minimum pitch of +15 and -15 degrees. This means that the center value is 0 degrees. Attach a pitch gauge to one rotor blade and check that the
collective pitch setting at centre stick is indeed 0 degrees. If the pitch value is slightly more or less then adjust the length of the connecting rod until
the value is correct and then do the same for the other blade.
3D Settings
With the center pitch value set now to 0 degree, it will be necessary to set the maximum positive and negative values to those shown in the tables
above. If the values do not correspond try increasing or decreasing the pitch curve, use the swashplate CCPM mixing function on your transmitter,
increase or decrease as necessary without causing binding. If you still have difficulty in obtaining the maximum positive or negative pitch values
shown in the tables recheck the pitch control rod lengths, and re-adjust as necessary.
8.Pitch Curve
This setting allows you to set the pitch of the main blades to the corresponding position of the collective stick. Adjust the main blades to give the
settings shown in the chart below. You may find it necessary to make minor adjustments to these values to suit your particular setup.
