Tamiya Tractor Truck Chassis: (Radio Controlled Model Review)1/14 Scale Electric Chassis:
Released by Tamiya on July 6, 1993, on the King Hauler kit (#56301), the Tractor Truck Chassis has been around longer than just about any other Tamiya Chassis, used for numerous models over the years, up until 2018 at least (the year of this review), with few modifications.

Buying a Used Tamiya Tractor Truck
Make a General Visual Inspection
Check the Body-Shell
If the body shell of your Tamiya Tractor Truck is broken, ripped or damaged in any way, this can be easily repaired with rubber solution glue. Also, for added protection and if available for your Tractor Truck model, fit an under guard to stop dirt and gravel entering the chassis. Drive Shafts and Turnbuckles
Examine the Drive System
On Belt driven models, the Drive Belts need checking at regular intervals for wear, tension and damage. If deemed necessary, adjust the tensioning pulley until the belt can be depressed in the centre by no more than around 5mm. If the belt was slack, also examine the drive pulleys for wear. The teeth should provide a well seated fit for the belt teeth and not be rounded on the corners. If the belt teeth do not fit snugly, change the pulleys as soon as possible. For top level racing it may be prudent to replace all belts and pulleys after each race meeting. Pinions and Spur Gears
Don't Neglect the Ball-Joints
Ball joints always cause problems. For top level Electric Truck racing, the plastic ball connectors should be checked and if deemed necessary, changed after every meeting. A simple thing like a loose fitting connector popping off, could easily end your race, so better safe than sorry. Steering Servo and Servo-Saver
Stabilizers
If body roll on your Tamiya Tractor Truck is a problem, handling can be improved with the use of stabilizers, anti roll or sway bars, stiffer tuning springs and, or, thicker silicone oil in the dampers. Don't Forget those Bearings

Hints, Tips and Information How to Charge Rechargeable Batteries for Peak PerformanceNi-Cad (Nickel Cadmium) Batteries
1/ All Ni-Cad Batteries have to be Discharged soon after use. This is to avoid the dreaded "Memory" effect that on subsequent re-charges can cause a momentary drop in performance during a race. A simple discharger can be made from a car 12v bulb.
Ni-Mh (Nickel Metal Hydride) Batteries
1/ Never charge Ni-Mh batteries at a current higher than 4.5 amps. Although these batteries can give a higher voltage than Ni-Cad Batteries, they are much more sensitive and easy to damage if charged too quickly. |
Hints, Tips and Information
Tire Compounds
Way back in the early 1990s when I first got into RC, most of the off-road models available came with chunky hard compound block tires that gave little or no grip on grass or dirt tracks. On-road didn't have this problem as they were still using sponge tires that with a coating of wintergreen based tire additive before each race to improve grip. There was even one guy who swore, before every race, he dipped his wheels in a glass of light ale. |
