What the Term Clod Stall in RC Rock Crawling Means

In the world of radio controlled rock crawlers, there is a term widely used by its enthusiasts and that is “clod Stall”. A clod stall is said to be caused by an imbalanced load on each motor of the rock crawlers. Say, for example, a quarter of a throttle could give off two joules of volts to the motor.

These volts will now be distributed to the front and rear areas of the rock crawler. Upon accelerating upwardly, the rock crawler will have a heavier load on the rear end since it is in the bottom part when going up and that is when a clod happens. And since both ends have a specific same amount of energy distributed, the rear will now have a difficulty carrying the load of the entire rock crawler while the front gear will spin with high intensity.

So in other words, the equal amount of electricity shared by two gears will now be insufficient to the rear because it now carries double the energy it receives.

A stall, on the other hand, is quite the same story with clod, wherein there will be a delay in allowing your rock crawlers to climb up due to the lack of energy the rear receives from the batteries. This will be quite frustrating since every rock crawler owners would want to have a smooth transition from driving crawlers on a straight and even path towards a steep slanting terrain such as the hill. This scenario has left radio controlled rock crawler enthusiast very eager to know how to solve the problem of experiencing a clod stall.

Methods to solve clod stalling

One of the methods rock crawler owners thought of was providing two different control sticks for both the front and rear gear of the device. Although requiring an advanced driving skill, enthusiasts advice for fellow rock crawler owners to do this not only to overcome clod stalling but to improve the rock crawler’s performance as well.

But the downside, on the other hand, is the added expenses for the owner since having two control panels will mean additional batteries and other parts to level up the crawlers capacity to climb up. Some enthusiast might ask if the additional expense is all worth it, but most, if not all, of those who made the decision to add another control stick, gained much better results. Better performance in the sense that the rear motor will now successfully resolve the issue of clod stalling.

To know better about the entire process, some owners wanted to verify if having two separate Electronic Speed Control or ESC will be able to fully solve the problem of experiencing clod stall. For all you readers out there if you are planning to do this process, you ought to know what type of machine you are operating- that way you could identify what type of electronic speed control will you attach in your radio controlled rock crawler.

Another thing to consider is the attachment of its wirings. Since there will be two ESC’s, you must be aware that aside from adding up an ESC, some other spare parts must be added as well. And one of these spare parts includes the control stick.

In having two control devices, it is very important to know the difference between the two of them, meaning, you need to label them accordingly whether the first stick is for the front and the other for the rear motor. And this is where an advanced driving skill comes in.

A rock crawler with two controls requires such skills because aside from driving two sets of wheels, there will be two sets of steering as well. And with that in mind, the owner must be mindful at all times not to confuse the control stick to the other to avoid damaging the radio controlled rock crawler.

Final Words

Finally, this I say, that having a radio controlled rock crawler is not simply just having a toy to play around, it also requires certain skills and it would even test your skills in improvisation and electrical knowledge but I guess the best part of all is seeing it conquer all types of terrain including those that are extremely steep.
