Traxxas TRX-4 Sport Kit (2019) - 82010-4 - Radio Controlled Model

   Introduced by Traxxas in 2019, the "Scale and Trail" TRX-4 Sport Rock Crawler - # 82010-4 - came as an unassembled kit, with a clear lexan Bodyshell, Canyon Trail 1.9 Tires and step-by-step manual, requiring a Motor, ESC, Battery, Charger, Radio System, steering Servo, and Paint to complete.

   The 4WD model is shaft driven, on a front motor design steel frame chassis with floor pans and adjustable wheelbase, sealed limited slip T-Lock (remote locking) differentials, coil spring over oil filled dampers, hardened steel universal joint drive-shafts, slipper clutch, high/low transmission and a full set of ball bearings.

   At present, the RC Model Manufacturers, Brands and Distributors covered by us are: ABC Hobby, Academy, Acme Racing, Agama Racing, Amewi, Ansmann Racing, ARRMA, Team Associated, Atomic RC, Axial, AYK, Bolink, Traxxas, Capricorn, Carisma, Carson, Caster Racing, Cen, Corally, Custom Works, Durango, Duratrax, ECX - Electrix, Exceed RC, FG Modellsport, FS-Racing, FTX, Fujimi, Gmade, GS-Racing, Harm, HBX, Helion, Heng Long, Himoto Racing, Hirobo, Hitari, Hobao, Hong-Nor, Hot Bodies, HPI, HSP, Intech, Integy, Jamara, JQ Products, Kawada, Kyosho, Losi, LRP, Maisto, Mardave, Marui, Maverick, MCD Racing, Megatech, Mugen, New Bright, Nichimo, Nikko, Nkok, Ofna, Pro-Pulse, Protech, PTI, RC4WD, Redcat Racing, RJ-Speed, Robitronic, Schumacher, Seben, Serpent, Smartech, Sportwerks, Step-Up, Tamiya, Team-C Racing, Team Magic, Thunder Tiger, Tomy, Top Racing, Traxxas, Trinity, Tyco, Vaterra RC, Venom, VRX Racing, WLToys, X-Factory, Xmods, Xpress, Xray, XTM, Yankee RC, Yokomo, ZD Racing and Zipzaps.

   This is an ongoing project, with new and "lost in time" RC Models and Brands being added as they are found and although most of those listed above have been covered in relative detail, some are still being researched and will be completed in the near future.

Sway Bars

   On most forms of RC model cars, Sway Bars, also referred to as Stabilizers, Torsion Bars, or more commonly in some parts as Anti Roll Bars, are often nothing more than a short length of spring steel, clamped to the chassis or sometimes the gearbox of the car, extending out to the lower wishbones direct or connected to the wishbones using short adjustable or fixed length links and ball joints, depending on their position.

   The principal behind the Sway Bar is simple. As the car enters a corner, weight is transferred to the outside wheels, the chassis rolls due to inertia and the suspension dips and grip on the inside wheels is reduced. In an effort to counter this dipping effect and transfer some grip back to the inside wheels to improve traction as you exit the corner, the sway bars transfer the dip of the outside, to pull down the inside wishbones, improving grip on the outside wheels and improving overall stability.

   Sounds complicated I know, but for some tracks sway bars can be a useful tool when you have exhausted all other options to correct your handling problems.

   Tuning your Sway Bars is quite easy.

Wheel Caster Explained

   Caster is basically the angle the steering kingpins or steering pivot points, leans back in relation to the horizontal when viewed from the side of the chassis.

   To test the effectiveness of your cars caster, place your model on a flat surface, point the front wheels straight ahead, and push the chassis over to one side to simulate body roll when cornering. You will notice that as the car leans over, all four wheels also lean over in the same direction. Tires provide the most grip when the wheels are perfectly vertical and the full width of each tire is flat on the ground. Body roll pushes the wheels past the vertical and reduces the amount of tire contact. Now, if you turn the front wheels as if cornering, and again push the chassis over, you will see that in this position, the front wheels are now more vertical, giving you better ground contact and therefore improved grip.

   Another effect of caster can be seen by disconnecting your steering servo and pushing your car along the floor. Because of caster and the kingpins leaning back, your car will naturally roll straight ahead.

   Obviously, the more body roll your car induces, the more positive caster you need to counter it.
