HBFP 2 Ring-like push rods direction?

Hello

I have the HBFP 2, I'm loving flying this heli indoors because of the bad weather outside. However I don't have that much room and the poor thing has had a few to many run-ins with the furniture. I snapped both the Ring-like push rods!
I have got two new one's today but I am not sure which way they are suppposed to go on? On one side it is smooth & on the other side there are markings. I have read somewhere before that they must go on a certain way. E.G marking's facing away from you, or is it towards you? Can any one please tell me which way the Ring-like push rods are supposed to go on. The rod's are the small one's that attach from the flybar to the centre hub set above the main blades.

Thank's
Marc

Basically it doesn't matter but I think they came Smooth side out...

It doesn't matter. I changed many of them and didn't realize it had a right or wrong way. Or a "right or wrong way."

Makes no difference.

Have fun!
