INJORA offers ASC18-37UD for this factory-brushless edition and its stock motor as a component option. The original 180 brushed motor is excluded; 24:1 and 13:1 are separate variants.
Installation notes
- INJORA lists the Ascent-18 Brushless, Scout II Brushless and APEX, and explicitly permits their stock brushless motor.
- Choose SKU ASC18-37UD, the 24:1 version. ASC18-37AS is a separate 13:1 option.
- INJORA's advertised 45.83% speed reduction compares 24:1 with its own 13:1 baseline. These factory-brushless editions already use about 20.52:1; do not apply that percentage to them.
- The package lists one complete transmission. Reuse and inspect the model's motor and mounting hardware; no receiver or battery change is established by this gearbox listing.
