It also features a simple bind button so pilots no longer need to carry a separate receiver or bind plug to bind. Dual antennas provide receiver diversity for solid signal and the long coax antennas help to provide maximum signal strength in all orientations for challenging installations where carbon fiber, metal and batteries shield the antenna. And with Spektrum DSMX 2.4GHz RF protocol the Spektrum SRXL2 Serial Telemetry Receiver provides remarkable range and interference free performance. ## Features - SRXL2 Technology - Low Noise Amplifier - Helps Reduce Interference and Produce Extended Control Link Range - Small, Lightweight and Perfect for Heli, Multi-Rotor and FPV Enthusiasts - Wide Voltage Input Range (3.3v -8.4v) - Dual Diversity Antennas ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B081H8PSKP | | Additional Features | SRXL2 Technology | | Best Sellers Rank | #90,775 in Toys & Games ( See Top 100 in Toys & Games ) #45 in RC Radio Receivers | | Brand | Spektrum | | Built-In Media | Spektrum SRXL2 DSMX Remote Serial Telemetry Receiver, SPM4651T | | Color | Black | | Connectivity Technology | Radio Frequency | | Customer Reviews | 4.7 4.7 out of 5 stars (166) | | Item Length | 1.1 Inches | | Item Type Name | Remote Serial Telemetry Receiver | | Item Weight | 0.05 Pounds | | Manufacturer | Spektrum | | Mfr Part Number | SPM4651T | | Model Name | Spektrum SRXL2 DSMX Remote Serial Telemetry Receiver, SPM4651T | | Model Number | SPM4651T | | Number of Batteries | 1 Nonstandard Battery batteries required. | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 605482427354 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Spektrum - **Color:** Black - **Connectivity Technology:** Radio Frequency - **Model Name:** Spektrum SRXL2 DSMX Remote Serial Telemetry Receiver, SPM4651T - **Special Feature:** SRXL2 Technology ## Images ![SRXL2 DSMX Remote Serial Telemetry Receiver, SPM4651T Small - Image 1](https://m.media-amazon.com/images/I/51hOOY42KZL.jpg) ## Questions & Answers **Q: I have had two of these. The unshielded antenna portion (clear) literally falls off without touching , engine on. Why is this happening?** A: This should not be happening. Spektrum's QA has always been hit or miss. I would definitely return them for either a refund or a replacement. **Q: I got a t-rex 150x dfc set coming and wanting to make sure this is all i should need to fly with my dx6e radio?** A: maybe not, if it come with the FBL is microbeast then you need a special cable and update the firmware, better option buy the regular DSMX satellite receiver **Q: How to you connect this to the rx2 on a fc6250hx? the supplied cable is 4 strand and the plug doesn't fit the 3 prog rx2 plug on the 6250** A: The 4 pins on the SRXL2 would need to be put on to the appropriate 3 pin connector. Flite Test has a video on how to do this for their Aurora 5 flight controller. The video is on you tube, just search for "Aura SRXL2 Setup and SRXL2 Telemetry Tuning". **Q: How do you know if it works? No lights come on.** A: Lights must come on. - blinking . . . before binding. If the plane is upside down, you will not get lights. Level the plane and then red the instructions. Then if nothing happens, its a bad receiver. ## Frequently Bought Together - Spektrum SRXL2 DSMX Remote Serial Telemetry Receiver, SPM4651T Small - Spektrum SRXL2 Update Cable: Receiver/Servo Male & Female/Female, SPMA3066 - Spektrum SRXL2 DSMX Remote Receiver, SPM9747 Medium --- ## 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.tn/products/175710164-srxl2-dsmx-remote-serial-telemetry-receiver-spm4651t-small](https://www.desertcart.tn/products/175710164-srxl2-dsmx-remote-serial-telemetry-receiver-spm4651t-small) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-26*
