Hirobo HI0412133 SCEADU SD control lever set for Sceadu SD helicopter linkage  [HI0412133]

Sceadu SD control levers

This control lever set is an RC-scale replacement part intended for the Sceadu SD helicopter platform, supplying the linkage needed between cyclic/collective servos and the swashplate. The set serves as a direct-fit replacement to restore mechanical connections after wear or impacts encountered during flying and routine maintenance.

Fit and role: the levers act as the mechanical interface in the servo-to-swash linkage, influencing travel, centring, and throw response. When installed correctly they support predictable control input and make small trim and tuning adjustments easier to implement from the transmitter.

Installation notes: verify alignment and neutral positions before final tightening, confirm free movement through full servo travel, and inspect for binding after the first power-up. Use thread locking where appropriate for metal-to-metal joints only if consistent with your existing hardware and practice; avoid forcing components beyond their intended range.
