This gearbox installs into the RB6.6/RB6 chassis with a minimal need for modification, allowing quick upgrades between race meetings. Clearances and mesh should be checked during fitting to ensure optimal operation.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will the UM734 cope with high torque motors?

The gearbox is constructed to handle typical racing loads, but final durability depends on motor power, gearing and driving conditions. Check gear mesh and bearings after high load runs.

Does fitting change vehicle balance?

The UM734 is designed to integrate with RB6.6/RB6 packaging. Any balance change is minimal, though drivers may notice different throttle response due to altered gear transitions.

Are special setup tips required after install?

After installation, verify gear mesh, check for binding and perform a short test run to confirm smooth shifts. Fine tune pinion and spur choices to match your motor.

Can this gearbox be used in endurance events?

With proper setup and maintenance, the UM734 can be used in longer events. Regular checks on bearings and gears between stints will help prevent issues.
