What kind of brushless modification is suitable for RC large S?
Among RC (remote control model) enthusiasts, Traxxas’ big S (Summit) is popular for its powerful climbing and off-road performance. However, many players hope to further improve their power performance by modifying brushless motors. This article will analyze the hot topics and hot content on the Internet in the past 10 days for everyone.What kind of brushless modification is suitable for RC large S?, and provide structured data reference.
1. Why choose brushless motor?

Brushless motors have higher efficiency, longer life and stronger power output than brushed motors. For heavy-duty models such as the Big S, brushless motors can provide more stable torque and faster response speed, especially in complex terrain.
2. Recommendations for popular brushless motors
According to recent RC forum and community discussions, the following brushless motors are popular choices for modifying the Big S:
| brand | Model | KV value | Applicable scenarios |
|---|---|---|---|
| Castle Creations | Mamba Monster X | 2200KV | High speed off-road |
| Hobbywing | EZRun MAX8 | 1600KV | Climbing and Comprehensive |
| Traxxas | Velineon VXL-6S | 3500KV | ultimate speed |
3. Precautions for modification
1.KV value selection: The higher the KV value, the faster the speed, but the torque will be reduced. As a climbing vehicle, Big S is recommended to choose a 1600KV-2200KV motor to balance speed and torque.
2.ESC matching: The brushless motor needs to be paired with an ESC that supports brushless (such as Castle Mamba Monster X or Hobbywing MAX8).
3.Heat dissipation problem: The brushless motor will generate a lot of heat when running at high speed. It is recommended to install a cooling fan or heat sink.
4. Recent popular modification cases
The following are modification solutions that have been discussed frequently in recent forums:
| Modification plan | Motor model | ESC model | User reviews |
|---|---|---|---|
| High speed off-road | Castle Mamba Monster X 2200KV | Castle Mamba Monster X ESC | Powerful and suitable for high-speed terrain |
| Climbing Comprehensive | Hobbywing EZRun MAX8 1600KV | Hobbywing MAX8 ESC | Sufficient torque and excellent climbing performance |
| ultimate speed | Traxxas Velineon VXL-6S 3500KV | Traxxas VXL-6S ESC | Extremely fast, but need to pay attention to heat dissipation |
5. Summary
Modifying a brushless motor can significantly improve the performance of the Big S, but you need to choose the appropriate KV value and matching ESC according to actual needs. Popular recent choices include the Castle Creations Mamba Monster X and Hobbywing EZRun MAX8 series. No matter which one you choose, pay attention to heat dissipation and power matching for the best experience.
If you are also a RC Big S player, you may wish to refer to the above data and choose a brushless modification solution that suits you!
