The new transmission has a DIG function that offers the tightest turning radius on a production crawler in the industry. When needed, simply switch from 4WD to front-wheel-drive by locking the rear axle from your transmitter. The transmission also includes a full set of ball bearings and all metal internal gears for strength and durability.
NOTE: Dig functionality requires an additional micro servo, not included. Micro Dig Servo SPMSSX107 (for Dig operation)
