HGLRC Zeus 1.6W VTX PRO PIT/25/400/800/1.6W Switchable FPV DVR Transmitter Built-in Microphone Support OSD 20X20mm M2 Upgraded Long Range Version For FPV Racing Drone Quad (MMCX)

Really long range and the heat sink does a good job of keeping electronics from frying (because it can get really hot at highest setting). I did replace the antenna to extend the range.

The instructions are minimal. No VTx tables were available. I couldn't get mine to do anything. And most of all, I couldn't get any customer support!

Love this little vtx. 1.6W is plenty to do just about any range flying you should need. It shouldn't be considered an ultra long range vtx by any means, but a few miles of range should be expected. I really like it's full metal housing as well that acts as a heat sink to radiate heat from the device. Just be careful about leaving it sitting on for too long, it will get so hot that it can physically burn you.

I can't find a link anywhere to download tables for this vtx. I manually set tables on betaflight but device ready status is still false and cannot control settings through osd (like changing power output or channel)

This works awesome for my race build , especially when flying alone due to the power. Used in pair with my runcam racer nano 4.

Over heats easily.

For its size and weight, this VTX packs quite a punch with its impressive 1.6W output power. I successfully installed it in my 5-inch quadcopter and had a solid signal to my Skyzone goggles without any issues. In terms of value, its less expensive then comparable VTXs with the same output power. Additionally, it comes equipped with a built-in heatsink, which keeps it from overheating even when working on the bench. Id definitely use this VTX again for my next build.

This VTX is build Tough, but is very lightweight. Simple standard wiring with nice length leads. Great image transmission quality. This transmitter works perfectly, and is a good value.
