Thats correct.

Linkage Rod A and Linkage Rod B are different links and go to different places

I had this problem as well, rod A cannot be made to 31.5mm with the 10mm rod and small links. Use the inside dimension of 2.5mm and it works out correct. I got this info from Gregor at Amain hobbies and it worked out fine good luck

Sorry, I misread what you were really after ..... I just rebuilt my head last night and this is what my settings were.....

Linkage Rod A should be 21.5mm

Linkage Rod B should be 30.5mm

Linkage Rod C should be 70.5mm

These are just arbitary settings and you still need to adjust pitch / tracking to suit afterwards.
