The 1/8" is all I had laying around, and this is my only heli.

I also had to redrill these wheels to get the correct ball spacing, and the design allowed me to eyeball the arm for the best spline alignment prior to drilling the new holes and before the balls were installed.

Will I get binding now that my arms are no longer parallel?

If your arms are not parallel then the linkages are not Equal in dimension.

You target the servo arm for the best servo spline alignment to the center of the bell crank rotation, then you drilled the holes on the servo arm.

If done correctly, your servo arm will be parallel to the bell crank arm given the linkage dimensions are EQUAL.

I meant to say my links are no longer parallel. I will get binding. The holes need to be offset slightly rearward so each link is 90 to the line from the ball to the center axis of the servo. The arm length at the servo end is less than at the bellcrank end. Need some blank wheels to redrill.
