Perfect addition to any quadcopter or drone. With its advanced 868MHz radio frequency technology, it provides superior signal quality and lower latency. Enjoy a reliable, crystal-clear connection with the ES900 dual receiver. - Low latency and high refresh rate, they are very suitable for FPV racing and long range FPV cruising while being ultra-light and ultra-small, making them very suitable for Tinywhoop. - Built-in a TCXO (temperature compensated crystal oscillator) , Improved Frequency Stability Over Temperature: The most significant benefit is the improvement in frequency stability over a wide range of temperatures. While standard crystal oscillators can drift in frequency as the temperature changes, a TCXO is designed to compensate for this drift. - Ultra-Compact & Lightweight: Designed with a PCB size of just 21.5mm x 16mm and a feather-light weight of 1.5 grams (excluding antenna). - Package includes: 1 x Happymodel ES900 DUAL RX ELRS Diversity 868MHz Long Range Receiver, 2 x antennas ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CKYK419B | | Customer Reviews | 1.0 1.0 out of 5 stars (1) | | Manufacturer | Happymodel | | Product Dimensions | 0.85 x 0.63 x 0.2 inches | ## Images ![Happymodel ES900 Dual RX ELRS ExpressLRS Diversity Receiver Iong Range Receiver for Micro Carbon Fiber FPV Racing Quadcopter Quad Frame kit RC Drone Frame Tiny Whoop 868MHz - Image 1](https://m.media-amazon.com/images/I/61A4V5erc4L.jpg) ![Happymodel ES900 Dual RX ELRS ExpressLRS Diversity Receiver Iong Range Receiver for Micro Carbon Fiber FPV Racing Quadcopter Quad Frame kit RC Drone Frame Tiny Whoop 868MHz - Image 2](https://m.media-amazon.com/images/I/61kSdKMptqL.jpg) ![Happymodel ES900 Dual RX ELRS ExpressLRS Diversity Receiver Iong Range Receiver for Micro Carbon Fiber FPV Racing Quadcopter Quad Frame kit RC Drone Frame Tiny Whoop 868MHz - Image 3](https://m.media-amazon.com/images/I/51Pc0lI3CaL.jpg) ![Happymodel ES900 Dual RX ELRS ExpressLRS Diversity Receiver Iong Range Receiver for Micro Carbon Fiber FPV Racing Quadcopter Quad Frame kit RC Drone Frame Tiny Whoop 868MHz - Image 4](https://m.media-amazon.com/images/I/51nqWnlyG3L.jpg) ![Happymodel ES900 Dual RX ELRS ExpressLRS Diversity Receiver Iong Range Receiver for Micro Carbon Fiber FPV Racing Quadcopter Quad Frame kit RC Drone Frame Tiny Whoop 868MHz - Image 5](https://m.media-amazon.com/images/I/51RXaDwcFfL.jpg) ## Customer Reviews ### ⭐ Misleading *by L***E on November 29, 2025* Item came damaged and disassembled leaving it completely useless. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/584878756-happymodel-es900-dual-rx-elrs-expresslrs-diversity-receiver-iong-range](https://www.desertcart.co.za/products/584878756-happymodel-es900-dual-rx-elrs-expresslrs-diversity-receiver-iong-range) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-24*
