The Tamiya Hornet has sort of a 2 link rear suspension mechanism, although it has limited room for some twisting. As you see from this video, this structure is good primarily for easy joy riding. The car is pretty jumpy even on grassland, therefore you simply cannot do serious racing… Continue reading
The good thing about ball joints in arms and linkages is that upon a crash it will take the impact and fall off … this way nothing will break. If it is a screw joint (which is most common in Tamiyas), something will have to break upon impact… Ball joints:… Continue reading
One reason why Tamiya cars are so easy to break is because they are using ABS as the primary material on parts are that frequently seeing stress, and that the holes for screws/axles/shafts are often very close to the edge. This steering knuckle of the Blazing Star is an example…. Continue reading
ABS plastic such as those of the Tamiyas can have fracture upon impact. This is especially common on arms and linkage around the hole for the step screws where the edge distances are just too short. You can fix it before it is too late. First apply super glue onto… Continue reading
If the dog bone shaft keeps falling off after landing a jump, a long term solution is to use CVD replacements. A cheaper quick fix is to shorten the upper linkage. By adjusting the upper linkage to make it shorter, the dog bone will less likely fall off. Another trick… Continue reading
To prevent the dog bones from falling out, the most effective measure is to limit the movement span of the arm. Zip tie can do the trick. Do make sure you provide sufficient cooling for the motor (and also the ESC). Even a stock silver can needs cooling to last!… Continue reading
