Center bearing holder for Turbulence D3

This is an RC-scale center bearing holder intended for use with Turbulence D3 helicopters. The component secures the center bearing that supports the main drivetrain stack and helps keep the transmission geometry aligned during flight and service.

Installation is typically performed during a mid-frame or main shaft service cycle where the bearing is inspected and replaced if worn. The holder's role is mechanical: it locates the bearing, resists axial movement, and provides a defined mounting surface so the main and tail drive components remain concentric.

When fitting the part, confirm bearing seating and axial clearance before final assembly, check that retaining screws are secure without over-torquing, and verify driveline smoothness after reassembly. Proper bearing location can reduce play and improve consistency in tail and main drive response during tuning.
