-Before starting, read all the sections of this guide. Take photos or videos of your disassembly, to assist you in reassembling the tail.

 This requires that the case be opened, the two batteries taken out of the case (they may stay attached to the control board), the control board removed from the case half, the four servo frame mount screws be removed to free both servos and the tail spine from the case half, and the servo pulley be removed from the servo (one screw in the center). The cable must be removed from the pulley (requiring 7 screws removed from the pulley) to remove the case half from the cable. This requires that the case be opened, the two batteries taken out of the case (they may stay attached to the control board), the control board removed from the case half, the four servo frame mount screws be removed to free both servos and the tail spine from the case half, and the servo pulley be removed from the servo (one screw in the center).

-Internally, the firmware refers to the servos as Servo 1 (the "top" servo) and Servo 2 (the "bottom" servo). The bottom (the one that emerges from the "bottom" of the case when the servo bracket is installed) servo cable goes to the bottom (closest to the board itself) PCB pins.+Internally, the firmware refers to the servos as Servo 1 (the "top" servo) and Servo 2 (the "bottom" servo).

-There are seven screws holding the pully assembly halves together. Three are at the edge, near the cable slot. And four more that hold the servo horn to the pully. All seven must be removed or loosened to free the cable from the pulley (which is required if the case is being replaced). The screws are M3 × 5.75 mm, Pozidriv PZ1 drive, 7.75 mm overall length.+There are seven screws holding the pulley assembly halves together. Three are at the edge, near the cable slot.

 To do this correctly, first power up the PCB with the new servo attached directly to the board. That will center or "home" the servo before you reattach the pulley. Secondly, make sure the pulley is in the following "ten minutes to the hour" position; the topmost screw head will also align with the servo mount rib below it (note that the servo splines may not line up perfectly and may land a tooth to the left or the right slightly or a particular trail might bias more towards the center screw): To do this correctly, first power up the PCB with the new servo attached directly to the board.
