Big feet

Hi all,
I have just bought a Trex 450s, pre built. During the inspection that I obviously carried out I noticed that there is about 1mm of play on the flybar. The flybar control arms are tight to the flybar control rods so I am left wondering how to remove this play.
Is the 1mm of movement normal?? Or should I get some thin washers and eliminate the movement totally?
My mate who is totally new to helis built his 450s from a kit and he has the same 1mm of movement.

Please excuse the poor diagram, its not my best sketch ever.

Any suggestions would be most helpful, thanks.

It's most likely because the flybar cage is not 'capturing' the see-saw tightly enough. With the plastic flybar cage, you have to squeeze it together to capture the bearings in the see-saw while tightening down the screws that hold the flybar. A lot of people fail to do that, and end up with 'end play' in the flybar system as you have described. I suggest you fix it, as it is not a good thing

double check Ball links??

Thanks for the help guys,
I did a search here on RCU and found simular questions from other trex owners.
I bit the bullet last night and striped the assembly down and added a washer, free play gone.

Thanks everyone
