My Posts This: Topic Forum | Continuing the head setup,
The 4 linkages going up to the swashplate need to be the same lengths, On mine they are set at 57mm.
Above the swashplate you have the washout hub and washout arms. These should be level, parallel to each other flat to the horizon, however you want to put it. Adjust this with the linkage between the washout arm and the flybar arm.
The next object of concern are the flybar arms, which on your model, should be slightly angled downward to prevent hitting the bottom of the blade grips. Just a few degrees is plenty, as long as the angle is the same on both, and the paddles are level to the horizon and each other.
Next up the line are the bell mixer arms, and again are level to the horizon and to each other. Ther are two possible ways to adjust this, the short linkage to the seesaw, or the long one to the swashplate. Make sure that both sets of linkages are the same length.
All of these things being level and even with each other is with the pitch on the blades at 0 degrees.
If you are getting more positive pitch than negative (+12-10 for instance), then lengthen the 4 linkages going up to the swashplate, raising it slightly, then resetting everything for level at 0 degrees.
Vice versa if you have more negative than positive.
Hope this helps.

longer links would solve the problem.
