RD S-Series ESC 25A is an advanced Electronic Speed Controller (ESC) designed for high-performance applications. Made in India, this model significantly enhances thermal and current handling capabilities. 

Where the S-Series 25A fits

The S-Series ESC 25A is the smallest controller in the Reflex Drive range. It is made for 2S to 6S LiPo packs, with a continuous rating of 20 A with active cooling for 5 minutes and no BEC. It is the recommended match for the RD4006 415KV, so it suits small multirotors, light camera platforms, student builds and prototype airframes where weight and cost are tight.

How it compares

Among our trapezoidal ESCs, the S-Series is the entry model. The RD D-Pro V3 ESC 60A handles 6S motors with high peak current, while the RD T-Series V2 ESC 60A and RD T-Pro V3 ESC 75A are for mid-size systems. For larger motors in our UAV motors range, look at the A-Series FOC ESCs. Use cooling airflow when you push the controller towards its rating.
