Kyosho LA426 - Motor Mount for LAZER ZX7.5 Chassis  [KY-LA426]

Function and fit details

The Kyosho LA426 Motor Mount Set is an RC motor mounting component purpose-built for the LAZER ZX7.5 chassis. It defines where the motor sits in the chassis and establishes the gear mesh relationship without modifying other drivetrain elements.

Role summary: preserve consistent motor alignment, enable repeatable gear mesh adjustments, and offer a steady platform for regular setup and servicing. Focus here is on fit and operational role rather than material specifics.

Installation and setup notes

• Remove the existing mount and confirm there is adequate endbell clearance before installing the LA426.
• Align the motor so the pinion meshes with the spur with minimal lateral movement, then tighten the mounting screws evenly to prevent plate distortion.
• Apply recommended torque values to the hex screws to avoid stripping and reassess gear mesh after initial runs.
• Route motor leads and the ESC away from the mount to prevent contact and to keep airflow for cooling.

The LA426 is used as part of chassis servicing and tuning procedures; small adjustments to setback or tilt will influence gear wear and noise. Make small changes and test on the bench before running hard on the track.
