This component, sold as Hirobo HI0304032, is an RC-scale replacement designed for the Lepton Lex range. It features a precise 16mm bearing seat to support tail or intermediate shafts and maintain correct alignment under operational stresses.
The holder improves mechanical alignment rather than changing power delivery. Confirm the bearing outer diameter is 16mm and that shaft dimensions fit the holder prior to installation; fitted correctly it reduces axial play and makes fine tail adjustments more reliable during setup and flight testing.
