Default Linkage length

Hello,
I had so many crashes and rebuilding with my 270cfx. Don't get me wrong. I like the bird.

What are the factory length of the Linkage?

Thanks,

The reason I am asking this because the negative pitch is not the same as the positive pitch. If I increase the negative to be equal to the positive pitch. The result will not be a balance -/+ pitch.
I think this can be fix mechanically. Any ideas how to do this.

Mechanical adjustment to make the pos/neg pitch becoming equal...

Is simply a matter of lengthen or shorten each linkage the exact same amount of turns

Doing so will raise/lower the swash position at servo center

If your swash is level...this adjustment doesn't change that...but you must start with the swash perfectly level - I'd recommend setting zero pitch at the same time

Only the max throw of the swash in each direction changes...thereby changing the pitch for pos/neg so they are equal

This method does not set zero pitch...it just changes the ratio of pos/neg

Steps in order:

1) Level the swash
2) set zero pitch
3) Check pos/neg
4) Adjust pos/neg with equal linkage turns
