Castle Creations Sidewinder Nano Micro Brushless/Brushed ESC (12.6V)

Castle Creations Sidewinder Nano Micro Brushless/Brushed ESC – 2-3S (12.6V Max)

Unlock serious performance in your micro-scale RC build with the Castle Creations Sidewinder Nano — a purpose-built brushless/brushed ESC engineered specifically for the rapidly growing 1/24 and 1/18 scale market. Running on 2S or 3S LiPo power, the Sidewinder Nano delivers precise throttle control, impressive punch, and the kind of tuneability and reliability that Castle Creations is known for — all packed into an extremely lightweight and compact package that fits where full-size ESCs simply can't. Selectable brushless or brushed motor compatibility makes this a versatile upgrade solution for a wide range of micro RTR and kit platforms alike.

At the heart of the Sidewinder Nano is Castle's proprietary CRYO-DRIVE Technology, which dramatically improves thermal performance during partial throttle operation — exactly where most real-world driving happens. The result is exceptionally efficient power output and reduced ESC stress during normal driving conditions, translating to cooler temps and longer runs. When you're ready to go deeper, the Sidewinder Nano is fully tunable via Castle Link USB adapter on a Windows PC or wirelessly via the Castle B-Link Adapter on a mobile device — both sold separately — letting you adjust parameters and switch settings on the fly at the track or trail without stopping.
