THE PROBLEM
For a dedicated pilot, executing a precision maneuver is complicated by anything that reduces the accuracy of the control inputs. This is principally thought of as a function of slop, which is why great effort is expended on ensuring the integrity of the control linkages. Unfortunately, wasted control motion because the servo itself deflects under the load (due to the rubber vibration-isolators give way) has been the price you pay for protecting the delicate servo electronics (from engine induced vibration). In other words, since nobody gives away servos, and because failure can mean loss of the model, that fact the little rubber vibration mounts result in decreased precision in the maneuvers is just part of the cost of doing business. This means anything that reduces wasted motion is good because it improves the precision with which your control input translates into your model's desired flight path - agreed?
THE SOLUTION
Fortunately, there's an easy fix if you fly a P6-family model helicopter because ProModeler engineers pioneered the concept of a servo bridge to preclude the wasted motion. Simply adding an AUD0060 Output Shaft Stabilizer kit to the three cyclic servos (the most highly stressed servos on your model helicopter because they control the swashplate) completely eliminates the problem without bypassing the fundamental function of the vibration dampers. How? By replacing the screw that holds the control arm with a shaft to which are added ball bearings. Then using support bridge across the top of the servo, the servo's wasted motion is controlled thus translating your control inputs into greater precision at the surface. It's elegant solution to wasted servo-motion under load because the rubber isolators continue to function as designed to protect the servo internals form damaging engine vibration.
The end result are maneuvers performed with greater precision. A more predictable flight path is important - even when learning to hover the model. Becoming an accomplished pilot is accelerated because the instantly becomes more predictable. Thoughts are transformed into beautiful maneuvers without loss of precision due to displacing the servo's output splined shaft with unwanted servo movement under load. As an added bonus, the bridge structure protects the servo in the event of a crash helping save money.
