Flybarless Rotor Head Systems > Grip ball spacing

A question for you guys. I see that most flybarless conversions space the ball on the grip away from the spindle a certain distance. How do I determine what distance to put the balls? Do I match it to the distance of the balls on the upper ring of the swash? That's what makes sense to me so I'd end up with a 1 -1 ratio of swash to grip inputs, but I thought I'd ask.

You space them so you get reasonable pitch range at full servo travel.

If the ball is at the center of the shaft, then you have 0 delta offset. If the ball is further away from inner swash plate, u have different ratio.

Some prefer (I think mostly 3D flyer) 0 delta offset while other prefer some -ve or +ve delta offset.

For different ratio, the higher the ratio, the more sensitive the cyclic and collective it is. If u choose 1:1 ratio or 1:0.5, your heli will have more precise cyclics and collective.

In the end, it is up to your selection I guess.
