How about this steering issue(Tornado BB)?

I turn on my electronics and using the steering trim get the front wheels fully straight.

I steer left and then let go of the steering wheel and the wheels does so and return to the fully straight position.

Now, I steer right and the wheels turns right, but when I release the steering wheel the wheels don't fully return to the fully straight position - Its slightly cocked to the right.

So, I try using the steering trim again to straighten it out from this cocked to the right position.

Now, when I steer right and release the steering wheel, it does and return to the straight position.

But, now when I turn left and release the steering wheel it turns left, but returns to a position - slightly cocked to the left.

The servo horn appears to return to the same exact position when at neutral.
At first I thought it was a problem with the servo, so I got replaced it with a new Futaba......same problem.
The servo saver thumb screw won't budge, but testing seems to indicate its stuck at the proper tension.
The 5cell humpback is fully charged and has plenty of power.
All the linkages seems to be in their proper place and working.

Any ideas?[sm=confused.gif]
