Well, Nuts!
I moved the recoil servo back just a tad too far and I found it hits the rotation box when the turret is turned 90 degrees to the right. Im going to try and move the servo forward maybe an 1/8 inch and then move it sideways maybe, and then have to rebuild a offset servo arm to stay in line with the barrel.

Im going to start pulling it apart maybe tonight and see how it goes.
