Default Ball link sizer ?


I am planning to order a ball link sizing tool from helidirect.com, but they have 2 sizes and I dont know which one to order for the TREX?

They say one is 3.5mm and the other is 4.75mm, which one do I need?

I measured my blade cp last night, its 3.5. So the trex must be the larger.

Others please pipe in if i'm wrong
