flapperon rigging

[egp8111 7]

I'm rigging the flapperons on my KFIII rebuild. I know this topic has been gone over before but I still have a few questions. I can get everything lined up per the manual with the stick vertical but I have more comtrol movement in one direction than the other. I've noticed the stick will physically move more one direction than the other due to it's design. Is this normal ? Also I've tightened up everything in the control system I can but the whole thing still seems kind of sloppy. With all the bends and fittings associated with this system I expect it to have some play but I'm wondering how much is normal?

Any suggestions tips or advise welcome. Hoping to get this thing flying soon!
