Well, I'm just flabbergasted.
I just installed a brand new blue EFlite swashplate on my BCPP, the balls were rather large I thought, and my links definitely only would go on one way, and just barely that way. Now what about the flybar hoops, surely those are one-way on yours?
Of course the larger Align and HeliMax links are definitely one-way, they are even marked, I hope I am at least not wrong about that!

But that's good, Tall Paul, that means if your links are not one-way you have more adjustablility (or something...)
I'm just glad I switched the radio to something that has adjustable sub-trims. It made setting mine up a lot easier for sure.
