Hirobo HI0304039 Front lever for Lepton LEX SWM helicopter cyclic control  [HI0304039]

Front lever for Lepton LEX SWM

This is an RC-scale front lever intended for the Lepton LEX SWM series, supplied under the Hirobo HI0304039 designation. The component is a direct mechanical element of the cyclic linkage, serving as the interface between swashplate movement and the rotor head control arms.

Fit and function: the lever supports precise linkage motion and plays a tuning role when balancing cyclic response. Inspect mating surfaces and linkage ball ends for wear before installation to ensure smooth travel and predictable control input translation.

Installation notes: remove the rotor head linkages and secure the airframe as required, transfer existing linkages carefully, verify neutral swashplate position and symmetric travel after fitting, and confirm full control throw without binding. This text describes model-scale maintenance and tuning only.
