RC crawlers are just as easy or difficult to understand as normal cars, depending on how interested you are. There is a lot to learn, but the easiest way to do this is to have at least an RC crawler and an interest in the sport.
For RC crawlers, a turn motor may refer to the number of times the copper cable rotates around the armature. The torque is the highest number of turns established for providing the needed power. Also, it could lead to a reduced RPM rating for the RC Crawler’s electric motor.
On the other hand, turn means how much cable is enveloped around the motor’s stator when it comes to a brushless motor.
When purchasing a brushless motor for your RC crawler, it would be best to compare brands. Some brands market kV rating while others prefer turn.
The more the turns on your motor, the less the RPM, but the more torque for your RC crawler.
So, how many turn motors for an RC crawler for speed? The most suitable turn motor for RC crawlers for speed is the 27t Torque Master or the 13t Crawl Master. These turn motors will certainly increase your RC crawler’s speed.
However, for extended runtime, go for the 20t Crawl Master or the 55t Torque Master. The 20t Crawler Master is ideal for going slow and having an extended runtime. It delivers 20 turns/volt, while the Torque Master offers 55 turns/volt. You can choose any of these two since they are robust and powerful.
What’s the best kV for RC Crawler?
kV and turn motor are related. kV is the motor’s speed rate. It typically refers to the RPM of an RC car’s motor per volt. It’s found in a brushless motor. The kV of an RC rock crawler is decided by the number of copper cables swathed around the motor’s stator.
The best kV options for your RC crawler include 2300, 1800, and 1200 kV. The factors determining the number of kV to go for depends on the speed you intend your RC crawler to attain. The 1200 kV is the most suitable if you want your RC car to go slow.
Suppose you choose a 1200kV with a one-volt electricity supply. You’ll get 1200 RPM. On the other hand, if you use the same kV with a 10-volt electric supply, it’ll deliver 120 RPM.
For a faster experience, use the 1800kV, while the 2300 kV will let you drive quickly and slowly. The more the kV, the higher the RPM.
Why Some Crawlers Feature Brushed Motors
RC crawler motors come in two types; brushless and brushed motors. The major difference is that the brushed option has commutators and a brush, while the brushless doesn’t. All the same, brushless motors have higher speed, longevity, and efficiency compared to their counterparts.
But most RC crawlers are equipped with a brushed motor. This is because of their unrivaled reduced-speed control. They come with the option of reducing or increasing the speed. This is vital for rock crawler racing. To race on tough terrain, you need high speeds, while descending this terrain calls for less speed.
Therefore, in terrain when you need to transition from ascending to descending, a brushed motor comes with the commutator’s dragging, which offers this motor a smooth slope to the throttle, allowing you to descend effortlessly.
However, you should get the brushless option if you need more speed.
What to Consider When Shopping for an RC Crawler Motor
The motor is a vital part of your RC car and is also very expensive, so it would be best if you didn’t go wrong. There are a few features to look out for to get the most suitable motor for your RC crawler, including:
As with anything else, you need to consider your budget when shopping for a motor for your RC crawler. With this in mind, you might have to purchase a less capable motor if you’re not on a spendy budget. However, if you have a lot of money, you can afford a more expensive motor for your RC crawler.
After determining your budget, you should look at the motor’s speed. Brushless motors` speeds are rated in kV, otherwise called RPM/volt. Therefore a ten 100kV motor will consume 10 100 RPMs for every volt supplied.
However, a brushed unit’s speed is rated in turn by the motor. So, if you want a brushed unit, choose one between 27 to 35 turns. For a brushless motor, this should be 2800 to 3300 kV.
The terrain you’re racing or riding on is also very important. This will determine if a brushed or brushless motor is more suitable. A brushless unit features an impenetrable can that doesn’t get dusty, while the brushed motor contains venting, exposing the brushes. This means it will get dirtier faster.
The slots are the motor’s stator. Some units feature three or five, while others have 8 or 12 slots. The higher the number of slots, the smoother the start-up it delivers.
Nevertheless, motors with few slot counts can deliver a better snap off the line, giving you the feeling of more torque. You can choose between the higher number of slots or few based on whether you prefer more torque or an effortless start-up.
Finally, you’ll consider the pole count. This is the number of the motor’s permanent magnetic poles. For instance, dual pole rotors in a brushless unit are merely one consistent magnet, while quadruple pole rotors in a brushed unit are four magnets on their rotor.
The higher the pole count, the more lightweight the motor, resulting in increased efficiency, optimal interior diameter to exterior diameter ratio, and surged frequency cogging torque.
Rock crawler racing is a fascinating activity. All the same, the robustness and durability of the RC crawler rely significantly on the motor. Each RC crawler features a motor, though, at times, the motor might not meet your requirements; hence you’ll have to get a more efficient one.
So, how many turn motors for an RC crawler for speed? The most suitable turn motor for RC crawlers for speed is the 27t Torque Master or the 13t Crawl Master. These turn motors will help increase your RC crawler’s speed.
