I'm in the final stages of assembling a RC12R5.2 kit and I hit a little snag. Using a Futaba S9650 servo and a small Kimgrough servo saver, one of the ballcups attached to the back of the saver hits the servo when the wheels are turned to the left. If I adjust the ballcup to be perfectly vertical it clears the servo, but if it twists a bit the edge of it hits the servo case.

Is there a good fix or trick for this?
