About the Sierra Max
Brushless Performance
The UDI RC Sierra Max combines a powerful 3660 2700KV brushless motor with a 60A waterproof ESC to deliver strong acceleration, smooth throttle response, and dependable power across dirt, gravel, sand, mud, and rough trails. Its full-time 4WD system and center differential provide excellent traction and confident control on changing terrain.
Heavy-Duty Drivetrain
Built for demanding off-road driving, the Sierra Max features steel transmission gears, upgraded steel CVDs, steel driveshafts, sealed front and rear differentials, and a CNC-machined aluminum center differential housing. These durable components are designed to handle high-speed bashing, hard landings, and challenging terrain with reliable performance.
Confident Handling
The front double wishbone suspension, solid rear axle, and eight adjustable aluminum oil-filled shocks work together to absorb bumps and improve stability over rough surfaces. A waterproof metal-geared digital servo, gyro-equipped DumboRC 2.4GHz radio system, and optimized chassis layout provide precise steering and greater confidence at higher speeds.

Buy it anywhere else and you can save $70... 5 stars for the truck, 1 star for the Amain price. (7-30-26)
MHandles like trash. The servo saver is so soft that the car is incapable of maintaining a straight line. Trimming it out is impossible because the front will just wander all over. The tires are poor, after only half a pack in dirt they look worn out and turn everything they touch blue. Working on the car feels very toy grade and not hobby grade. At this price point there are much better options for the money. Save yourself the frustration and skip this.
