My T-Rex 450 Pro has a very slight play in the tail rotor shaft.
I didn´t see any shims inside the box to solve this problem.
Is it normal or I can have some problem with the precision of the rudder control?

Thanks
Marcelo

Side to side. I think is ver easy to solve this problem with a shim...the problem is to find the right shim

Side to side play causes a problem with the accuracy of the pitch slider, but it seems to be inherent to Align quality control. Trying another t/r shaft or another t/r bearing may fix the problem.

The 450 pitch slider is inherently sloppy, so unless you are doing precision FAI style flying, a little bit of side to side play will probably be alright. You might have to turn your gyro gain down a little bit to compensate.
