Removing slop from the steering system
Most of the play in the steering can be attributed to 2 bushings being to long . They can be seen here in the picture below
You will need a shim with a inner diameter of 4.5mm or a material you can make a 4.5mm hole in to act as a shim. I actually used some lexan spaces I had handy . Slip one over the bushing .
Then re-install in bellcrank and test for play if bell crank moves freely and play has been reduced to a satisfactory level repeat for other side . On one side I used a shim on the bottom of the bushing and on the top.
The next thing that causes play is the link that runs to the servo .
I recommend just replacing it with a adjustable link with ball end's ( I installed the aluminum servo arm just because it wasn't doing anything just sitting in my parts box)
Now the only remaining play is in the stock servo which isn't very much at all.
keeping your servo saver tight
remove bell crank system add a washer or shim with a 7mm inner diameter at the bottom of the bell-crank shaft (mine was made from copper)
Then install a o-ring on the bottom of the threaded portion below the adjusting nut .
reassemble and the adjusting nut should not be able to self adjust .
