This CNC-machined 1st gear adaptor serves as a scale replacement for the XRAY NT1 drivetrain. The aluminium body improves rigidity between spur and pinion, helping to maintain reliable gear engagement in competitive 1:10 on-road cars.
Focused on NT1-compatible geartrains, the unit is meant as a direct swap for stock plastic or alloy adaptors without reworking the gearbox layout. The red coating makes inspection and alignment checks faster trackside.
Fitting is straightforward for those familiar with NT1 setups: swap the adaptor into the original location, confirm concentricity with the motor pinion and spur, then set backlash and mesh precisely. This component supports alignment and tuning tasks rather than wholesale drivetrain redesigns.
