Applications
Q: How can I tell if my brushless motor or ESC is overloaded in an RC boat?
A: If your brushless motor or ESC gets too hot to touch, the boat loses power, shuts down, or the battery drains quickly or puffs, they may be overloaded. High current draw is another warning sign, especially if it nears the ESC’s limits. To prevent this, use a properly sized propeller, lower KV motor or ESC timing, improve cooling, and ensure your ESC and battery are rated for the load. Always test gradually and monitor temperatures.
