I changed brands from the original servo used to get a stronger gear train, after reading that the original servo had gear train failure. The maker of the servo I used says that their Karbonite gears are 4x stronger stronger than the standard white nylon gears and even after hundreds of thousands of cycles it will not show any signs of wear.

The arm is made from 6061-T6 aluminum fitted to the servo's heavy duty servo arm. The roller assembly is a hardened and ground steel pin with a Ultem, glass filled resin, sleeve that is free running. This arm will not fit the Airtronics 94102 servo, the spline shafts are different.

I tested it out in a working game at the Ann Arbor Pinball Museum. The New Servo and Arm works great! Travel adjustments may be required to the servo's movements using the potentiometers on the servo driver board. Further tests using a Hangar 9 Digital servo current and volt meter. I found the servo I used drew about half the current, than the original servo, while moving the blinders. And one fourth the current while holding the blinders open & closed. My first production arm and servo is now in operation at the Ann Arbor Pinball Museum. The original plastic arm had a crack in it by the pin and roller.
A second servo and arm assembly has been installed along with a replacement driver board in my friends game. The replacement driver board from Pinnovations was purchased from Pinball Life. Plug and play! No adjustments were needed on this installation.
