Spektrum SPMXSE2525RX 2-in-1 25A SLT ESC/RX — 1/18 Crawler

The Spektrum® SPMXSE2525RX is a 2-in-1 25-amp ESC and receiver combo designed specifically for 1/18 scale RC crawlers. Integrating the ESC and receiver into a single compact unit simplifies electronics installation, reduces wiring, and saves critical space inside tight 1/18 scale crawler chassis. The SLT (Surface Long Throw) protocol delivers reliable wireless connectivity and enables wireless programming of ESC parameters without the need for a programming card or USB interface — adjust throttle punch, drag brake, and other settings directly from a compatible SLT transmitter. Purpose-built crawler ESC tuning delivers the smooth, precise low-speed throttle control that rock crawling demands.
