Please with the product. Review: It's working well as long as you update the heatsink and fan. - I had a FlyZone 2000mW (or just 2 Watts) and for some reason it just was getting too hot. Eventually the voltage regulator finally went out. This one has a good and a smaller fan but I've added another along with a larger metal heatsink and so far it is doing great. Just remember the more power the more heat will be generated so you have to compensate for that in some way. ## Features - 【Antenna Core points】: Flysight black mamba 5.8Ghz FPV Trasnmitter here with SMA ANTENNA CONNECTOR; Black Mamba TX5820 V2 as the transmitter FPV VTX, Be sure before using: Check the warning label``Power VTX with Antenna on’’ on Black Mamba,Fix the antenna first before powering Flysight black mamba video transmitter,otherwise,it will be burned;Remember it in our mind at any time,please!!! - 【Power Output for Camera】: Flysight black mamba 5.8G FPV VTX here with 6-28V power output;the input power voltage of this FPV transmitter same with its output power voltage,so it CANNOT be used for your cameras like Gopro Only with 5V power supply!!! - 【Cool Design】: Flysight FPV Vtx comes with the cover and a small size with light weight which make you to carry easily & on-board quiet fan build-in for good heatdissipation; Meanwhile, switch channels much more convenient for using this Flysight transmitter for rc drone via a high brightness LED display; - 【5.8GHz for FPV performance】: Flysight black mamba's max distance is about 8-9KM at open area without obstacles.This 5.8Ghz video transmitter with high sensitivity multiple 40channels,wireless video is not affected by 2.4Ghz R/C Radios;Connecting Flysight Black Mamba to DJI Phantom 2 / Black Pearl - No soldering;it can transmit the video signal from the drones,you can enjoy flying,taking photos and filming by it; - 【Warranty life】: Black Mamba TX5820V2 as the video transmitter for FPV drones,Flysight offers 16months warranty once you meet any problem.After 16months,we still offer after-sales service for you all the time. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01L1OFDGO | | Age Range (Description) | Adult | | Age Range Description | Adult | | Are batteries included? | No | | Battery Cell Composition | Alkaline | | Best Sellers Rank | #35 in Video Transmission Surveillance Systems | | Brand | Flysight | | Brand Name | Flysight | | Color | Black Mamba 2000mW Long Range Vtx | | Connectivity Technology | 5.8 GHz | | Control Type | Remote Control | | Customer Reviews | 4.3 out of 5 stars 87 Reviews | | Includes Rechargeable Battery | No | | Includes Remote? | No | | Item Dimensions L x W x H | 2.17"L x 1.38"W x 1.06"H | | Item Weight | 52 Grams | | Manufacturer | Shenzhen G-VISION Technology Co.,Ltd | | Maximum Range | 9000 Meters | | Media Type | MP4 | | Model Name | TX5820 V2 | | Model Number | TX5820 V2 SMA | | Optical Sensor Technology | CMOS, CCD | | Part Number | TX5820V2 | | Video Capture Format | MP4 | | Wireless Communication Technology | 5.8Ghz FPV Video Transmitter | ## Product Details - **Brand:** Flysight - **Model Name:** TX5820 V2 - **Age Range (Description):** Adult - **Color:** Black Mamba 2000mW Long Range Vtx - **Connectivity Technology:** 5.8 GHz - **Item Weight:** 52 Grams - **Video Capture Format:** MP4 - **Control Type:** Remote Control - **Maximum Range:** 9000 Meters - **Wireless Communication Technology:** 5.8Ghz FPV Video Transmitter ## Images ![Black Mamba 5.8Ghz FPV Video Transmitter 40CH Wireless Audio Video FPV Vtx Transmitter for RC Drone MultiTotor Quadcopter (SMA ANT 6-28V,NOT for Gopro) - Image 1](https://m.media-amazon.com/images/I/31aJ8Hn2HKL.jpg) ![Black Mamba 5.8Ghz FPV Video Transmitter 40CH Wireless Audio Video FPV Vtx Transmitter for RC Drone MultiTotor Quadcopter (SMA ANT 6-28V,NOT for Gopro) - Image 2](https://m.media-amazon.com/images/I/61ntvCou2ZL.jpg) ![Black Mamba 5.8Ghz FPV Video Transmitter 40CH Wireless Audio Video FPV Vtx Transmitter for RC Drone MultiTotor Quadcopter (SMA ANT 6-28V,NOT for Gopro) - Image 3](https://m.media-amazon.com/images/I/61EPPSQCKwL.jpg) ![Black Mamba 5.8Ghz FPV Video Transmitter 40CH Wireless Audio Video FPV Vtx Transmitter for RC Drone MultiTotor Quadcopter (SMA ANT 6-28V,NOT for Gopro) - Image 4](https://m.media-amazon.com/images/I/71H4FenbKYL.jpg) ![Black Mamba 5.8Ghz FPV Video Transmitter 40CH Wireless Audio Video FPV Vtx Transmitter for RC Drone MultiTotor Quadcopter (SMA ANT 6-28V,NOT for Gopro) - Image 5](https://m.media-amazon.com/images/I/61o5jLjj3PL.jpg) ## Questions & Answers **Q: Is the audio input expecting a dc or ac signal from a microphone?** A: everything on your audio video tx is DC. Most AV Tx operate on 12V. Most FPV cameras operate on 12V while a few operate on a range of voltages from 4.6V to 24V. The only thing on an RC system that produces AC is the electronic speed controller, the output to the motor is AC **Q: What is the green nc wire for?** A: Dear James McCabe , Thanks for your kind asking. Sorry for the late reply because we were on CNY long holiday. The green nc wire for PPM function of the RC radio of the drone. Hope thie can help you. Flysight sales team **Q: Where can I get a wiring harness for this transmitter?** A: What do you mean? The item includes several wires to meet the needs of the user. The published images depict the meaning of each wire/color **Q: What battery should I use with this? I want to get about ~35 minutes of use, only using a single camera.** A: It pulls 1 amp at 12v, so that means you would want 3s 1000 mah, in 35 mins you would pull about 600mah/60% of the change out the pack. Lipos do best with using 80 to 85% max of the packs compacity so that would be idea. If you ran a 6s 1000mah you could safely get 80 to 85 mins burning 85% of the pack. Remember a 2w transmitter is gonna make mad amounts of heat and moving air is a must, this unit in a static environment at 2 watts/2000mw is gonna be a issue evenc with the built in fan. If you use will be in a static environment then you will deff want to place a fan blowing on it or you will no doubt have heat problems. I would simply run a 3s 2200mah pack and know that up to 100 minutes of so is absolutely gonna be safe on the pack. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Black mamba from flysight. *by B***N on October 28, 2025* Straightforward transaction.
