Hello comrades, who have the ball as links in the T Rex 500, since failing to manual, do not know what size you need.

Thanks and best regards

To get zero pitch at center, with swash driver centered as per manual, and servo arms at 90, I needed to shorten the 3 servo to swash links (D links) to about 46mm. My swash to grip links are at 70.

I just measured mine and they are at 70mm / 49mm.

I guess this may also depend on the servos you are using? They don't always have the spline positions. I am using JR DR3421's.
