Hi, you should make all servo push rods longer. This will increase collective pitch so that it can be at 0°. |

The servo links are fixed length, but the links from the swashplate to the main blade grips are adjustable for zero pitch. You tweak the Spirit Subtrim (tuning) parameters to level the swashplate. |

Hi Yes i have done it that way,but the geometry is not perfect either the servoarm arent at 90deg or the radius arms. i planing to rise the 3 servosupport abaout 1mm then the geometry should be perfect. //Latjo |
