2S LiPo CAPABLE
The RS4 Sport 3 features a versatile electronic speed controller that can be used with modern lithium-polymer (LiPo) or nickel-metal hydride (NiMH) batteries. Please note a LiPo adapter plug is not included, your model shop will be able to provide one.
Fits a Wide Variety of Batteries
The RS4 Sport 3 chassis can fit lithium-polymer and nickel-cadmium packs of various sizes, including the extra-long 7-cell Ni-MH packs. Whatever your power requirements, it can hold it all! A thick hook-and-loop strap holds the pack securely in place, and a simple battery block screws into place to allow you to adjust the weight distribution forward or backward for extra steering or acceleration.
Full-Time Four-Wheel Drive
The RS4 Sport 3 features full-time four-wheel drive to give you the most control and precision on the road or track. All four wheels are driven by heavy duty gear differentials at the front and rear, just like a real car. The extra traction gives you increased acceleration and cornering control for maximum confidence and fun.
Sealed Shaft Drivetrain
The drivetrain of all the RS4 Sport 3 models features the motor mounted longitudinally in the molded chassis, next to the long driveshaft that goes down the center of the car. The entire drivetrain, including the central driveshaft and gear diffs, is completely sealed to prevent dirt, rocks and debris from damaging or binding the drivetrain. The driveshaft, diffs and axles spin on ball bearings to maximize drivetrain efficiency.
The central driveshaft that connects the front and rear differentials is easily accessed from underneath the chassis. This allows the drivetrain to be completely sealed to protect it from rocks and debris no matter where you may want to drive your car.
Option: Carbon Fiber Driveshaft Cover
You can easily replace the stock driveshaft cover on the bottom of the chassis with a carbon fiber cover that provides extra stiffness and extra-cool looks.
Easy Access Differentials
Getting to the differentials for quick adjustments is a matter of removing just 4 screws - this allows you to pop out the diff and change the grease, check the gears or just give it a general service.
4-Gear Metal Diffs
Bevel gear differentials at each end of the car transfer power from the driveshaft to the dogbones and axles that drive each wheel. The all-metal construction allows the drivetrain to withstand powerful brushless motors for easy upgrading in the future. Rubber-sealed ball bearings support the differentials and each diff can be tuned independently by changing the diff grease.
Option: Diff Spool
The optional diff spool removes all diff action for direct traction and braking action from your trigger finger straight to the wheels.
Double-Wishbone Fully Adjustable Suspension
The suspension of the RS4 Sport 3 uses the race-proven double-wishbone suspension design, similar to a full scale modern race car. You’ll be able to control the anti-squat and anti-dive of the front and rear arms using the standard pivot blocks, and the option parts allow you to adjust the sweep and toe angles. You'll also be able to easily change the roll center front and rear with the racing-style vertical ballstud mounting on both the inner and outer camber link mounts. Multiple shock mounting positions provide a full range of shock suspension angle adjustment to suit different road conditions.
