The installation was straight forward and gave the benefit of eliminating a receiver battery with the compatable receiver used. The throttle response is rather sharp requiring a gentler than normal operation to avoid over rapid acceleration, however operated well with the RS540 motor used. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/50857390-auto-sport-tuned-20-esc-electronic-speed-controller-for-tamiya](https://www.desertcart.be/products/50857390-auto-sport-tuned-20-esc-electronic-speed-controller-for-tamiya) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-16*
