UDIRC Sierra Max UD1002P 1:10 4WD Brushless RC Desert Trophy Truck (RTR)

The UDIRC Sierra Max UD1002P is a full-size 1:10 desert trophy truck — 600 mm of tube-frame chassis, real HobbyWing electronics and a steel gear transmission from end to end. This is the updated version of the UD1002SE, and the upgrades are all in the drivetrain.

Where the earlier car used plastic in places, the UD1002P runs oil-sealed differentials with steel bevel gears front, centre and rear, a steel 58T centre-diff gear, and steel universal drive shafts. The receiver has a gyro built in for high-speed stability, and the Dumbo X5E transmitter gives you real adjustment — sub-trim, EPA and gyro gain on a dial.
