CCPM and adjustable Bell-Hiller Ratio for Different Types of Flying Styles

Note: This picture is for illustration purposes only, as it shows A1+ B2 +C2, which is none of the standards:

Normal (Starters and Scale helis): A1 + B1 + C1
F3C flight (Intermediate): A2 + B2 + C1
Advanced 3D flight : A2 + B2 + C2

Whatever of the above you choose, don't forget that in the end, at 50% throttle on the radio:

• All three CCPM servos should be 90% to the main shaft.
• Swashplate must be level, and at middle of it's trajectory.
• Washout control arms must be level, both confronted.
• Flybar control arms level.
  
• Elevator Swing arms must be level, both confronted.
• Main blades at 0°
  

In other words,



All of your links need to be symmetrical in length. Hopefully they will all be, although there is no need for the 3 CCPM links that link with the servos to be identical. A slight variation here is allowed.
