The XILO STAX FPV video transmitter checks all the boxes on a must have VTX for FPV drones. It has tons of features like adjustable power, smart audio, MMCX connection, break-away tabs for mounting options, conformal coating, push button operation, LED indicators and more! The best part is even with all these features it is priced to be extremely affordable. Now you don't have to choose between quality and price; you can have both!

Features

Multiple Power Output Settings

With the XILO STAX VTX you can choose the power that best fits your needs from 25mW up to 600mW and PITMODE. Changing power settings is as easy as pressing a button, or changing via your radio sticks with the Smart Audio integration.

Smart Audio Connectivity

Smart Audio is a must for FPV pilots these days, and the XILO STAX has you covered with officially licensed S/A functionality. Simply connect the S/A pad to an open UART on your flight controller and assign that port to Smart Audio in Betaflight. Now you can change channels, power settings and more with just your controller! No need to manually change settings with a button or physical switches.

Power and Frequency Buttons

Don't want to mess with the Smart Audio features? No problem, the STAX also has onboard buttons to easily manage your power and frequency settings. The onboard LEDs read out each setting so you can visually see what mode you're in. Works great as a back-up as well if your Flight Controller doesn't support a S/A connection.

More Ways to Mount

The XILO STAX is designed to mount to standard 30.5x30.5mm mounting holes. This allows for easy stacking on top of ESC/FC stacks, or securely mounting in the rear of many airframes. But if you don't want to mount it like that you can simple break off the perforated tabs to make for a even smaller form factor of just 20x34mm! Stick it down with tape, cable ties, 3D prints etc. It allows you to get creative and make this VTX work in just about any frame.

Quality Control

Each XILO STAX VTX goes through a vigorous QC process at the factory. All electrical components are conformal coated to protect against shorts from unwanted moisture and external forces. Every unit is tested for 100% functionality and goes through a burn-in program to ensure you get working VTX that will hold up to your flying. We know how critical your video signal is, so XILO does everything possible to make sure this product is solid.
