When it comes to a variety of RC cars, you can trust Traxxas; there are different Traxxas scale RC cars available. They come in different sizes, designs, specifications, and features. One of the best RC cars is the Traxxas TRX-4, and you will find some of the best features.
The Traxxas TRX-4 RC car is a 1:1o scale car, and it comes in two models, the TRX-4 Sport and TRX-4 Scale and Trail Crawler. The TRX-4 Crawler is an imitation of a Jeep, while the TRX-4 Sport looks like a pickup truck. The Crawler is bigger and heavier than the Sport.
These two TRX-4 models are unique, so it is essential to know the features available on both cars. This will help you make informed and accurate decisions when choosing the model to purchase.
What Scale Is The Traxxas TRX-4?
The Traxxas TRX-4 is a unique RC car; having two models means you can get the same brand with two different features. Both TRX-4 RC cars are 1:10 scale cars. When an RC car is 1:10 scale, it means it is one-tenth the size of a real car. That means the Traxxas TRX-4 is ten times smaller than a real car.
Traxxas TRX-4 Scale And Trail Crawler
You should expect some features in any Traxxas RC car: ruggedness, durability, power, and fun. The Crawler is no exception; it is built for rugged off-road terrains. The TRX-4 Scale and Trail Crawler has a length of 23.07 inches, a height of 11.48 inches, and a weight of 7.43 pounds.
The front track of the Crawler is 9.78 inches, and the rear track is also 9.78 inches. It has a ground clearance of 3.14 inches and a wheelbase of 12.75 inches. The front and rear shock lengths are 3.54 inches each, and the approach angle is 56.49°. The break-over angle is 57°, and the departure angle is 41.67°.
The size of the front wheels is 1.9 x 1.02 inches, as well as the rear wheels. The front and rear tires are 4.64 x 1.89 inches in size. The speed control of the Crawler is XL-5 HV. It uses a High-torque brushed motor that weighs 390 grams, a voltage of 16.8 volts, and 21T reverse rotation turns.
The input voltage of the electronic speed controller (ESC) is 6–7 Cells NiMH, 2–3S LiPo, the ESC weighs 74 grams, it has a breaking current of 60 amperes, a continuous current of 18 amperes, the forward peak current is 100 amperes, the reverse peak current is also 100 amperes.
The Crawler is designed to have a rugged and functional roll cage, tough fender flares, and the ESC is completely waterproof. The front bumpers are designed with replica winch and tow hooks, and the rear bumpers are equipped with functional spare tire and scale accessories. This RC car can reach a top speed of over 50 mph.
The Traxxas TRX-4 Scale and Trail Crawler have five driving modes; race, sport, crawl, trail, and training. In sport mode, the Crawler can move forward, reverse, and brake. In training mode, the car can move forward fifty percent, brake, and reverse fifty percent.
In crawl mode, the Crawler can move forward and reverse; there is no neutral with hill-holding brake. In race mode, the car can move forward, brake but cannot reverse. The car can move forward, reverse, and brake in trail mode, with drag brakes for trails in neutral.
The Crawler has a rigid steel frame, a 1.5 millimeters thick steel frame that increases the torsional rigidity, the bumpers make the fore and aft adjustable; the rugged rock rails make the width adjustable. The wheelbase of the Crawler is adjustable, so it has four positions, 336 mm, 324 mm, 312mm, and 300mm.
The Crawler has a steel gear transfer case, hardened steel rear axle shafts, tough 6 millimeters stub axles, remote-locking steel gear differentials, steel front CV driveshafts, and shaft driven four-wheel drive. You can easily access the battery due to the hinged battery strap.
The Crawler works with a TQi 2.4GHz 4-channel transmitter that works with the Traxxas Link. The transmitter has adjustable steering, throttle sensitivity, and throttle endpoints. The car has a 2071X Metal Gear Servo. The cost of purchasing a Traxxas TRX-4 Scale and Trail Crawler is $500.
Traxxas TRX-4 Sport
The Traxxas TRX-4 Sport is one of Traxxas's least impressive RC cars; however, it still has some impressive features. The top speed of the TRX-4 Sport is 5 mph, how ironic for a car called Sport. If you want an RC car to participate in races, you should not get the TRX-4 Sport.
The length of the TRX-4 Sport is 21.93 inches, the weight is 5.79 pounds, the height is 9.47 inches, the rear track and front track are both 9.78 inches. The wheelbase of the TRX-4 Sport is 12.28 inches, it has an approach angle of 58.82°, the break-over angle is 59°, and the departure angle is 45.83°.
The size of the front wheels is 1.9 x 1.02 inches, the rear wheel also has the same size, the front and rear tires are 4.64 x 1.89 inches. The Sport uses an XL-5 HV speed control, a High-torque brushed motor, and a 21T Reverse Rotation electric motor turns. The weight of the motor is 390 grams, and it requires 16.8 volts to work.
Similar to the TRX-4 Crawler, the Sport also has five selection modes, race mode, trail mode, sport mode, crawl mode, and training mode. In the race mode, the car can move forward, brake, but cannot reverse. In the sport mode, it can move forward, reverse, and brake.
In trail mode, the car can move forward, reverse, brake, and has a trail-tuned brake on neutral. In training mode, the car can move forward fifty percent, brake, and reverse fifty percent. In crawl mode, the car can move forward, reverse, and brake on neutral. The TRX-4 Sport uses a MOSFET transistor.
The input voltage required by the ESC is 6–7 Cells NiMH, 2–3s LiPo, it has a forward resistance current of 0.004 ohms and a reverse resistance current of 0.004 ohms. The forward and reverse peak current of the ESC is 100 ampere, the breaking current is 60 ampere, and the continuous current is 18 ampere.
The motor of the TRX-4 Sport has an internal cooling fan, motor retention that is separated from the gear mesh, and precise gear mesh adjustments that have been preset. Similar to the Crawler, the Sport also has four wheelbase positions, 336 millimeters, 324 millimeters, 312 millimeters, and 300 millimeters.
The front suspension has 3 pan-hard links, and the rear suspension has 4 triangulated links. The TRX-4 Sport has oil-filled coil-over GTS shocks that are limited to only TRX-4 chassis. The ESC of this RC car is completely waterproof, and it has 2-stage low voltage indicators.
The TRX-4 Sport has a clear and painted body design, side view mirrors, expedition rack, traction boards, spare tire mount, and external LED lighting for the bumper, roof, and expedition rack. This RC car uses a TQ 2-Channel Radio System, and you can purchase it for $370.
The TRX-4 Sport is lighter than the Crawler, although the Crawler is faster. The Sport uses spool differentials, while the Crawler uses to-lock differentials. The TRX-4 Sport is more user-friendly, flexible, and convenient to use than the TRX-4 Crawler.
