Description:

Dynon Avionics recently started shipping an improved version of the capstan servo installation kit (SV32C, SV42C, SV52C) that comes with each capstan servo. The new version of the capstan servo installation kit improves safety and longevity through a redesign of the steel braided cable included in the kit. Dynon Avionics is making this safety and longevity improvement available to customers that have previously purchased and/or installed Dynon Avionics capstan servos.

This bulletin does not include the SV32, SV42, SV52 or the SV32L, SV42L, SV52L, which use a linkage arm, not a capstan.
