The XILO Phreak FPV Racing Quadcopter is a stretched X, ultra-durable, easy to work on, carbon fiber airframe. The Phreak was created to offer FPV racing pilots a solid racing frame at an affordable price. We know that racing frames take a beating, so you want a quad that is easy to repair and work on, and won't cost an arm and a leg. If you're looking for a quality frame at a great price, then this XILO Phreak is the quad for you!

The airframe features removable 4mm carbon fiber arms and 2mm thick top and bottom plates. The arms are sandwiched between the bottom plate and 2mm battery plate giving you an incredible 8mm thick of carbon fiber at the center of the body. Each arm is secured in place with just 2 screws and a steel press fit nuts in the main plate. This allows you to swap an arm by simply taking out 1 screw and loosening the other, pulling the arm out of the slot. It is very fast and easy to work on!

Each 4mm arm and plates are CNC milled out of a solid sheet of high-quality XILO carbon fiber. The outer weave of the carbon fiber runs 100% down each arm of the XILO Phreak (0/90 weave), maximizing the strength of the carbon and arms. The center layers are offset at 45 degrees providing even and balanced strength throughout the entire plate.

This XILO frame kit includes a set of molded rubber camera brackets for easy and secure mounting of your micro sized FPV camera. No need to 3D print a set, these mounts are durable, semi-rigid, and work perfectly to hold your camera at any desired angle. The brackets can easily be moved up or down on the standoffs to hold the camera at the perfect height for your build.

The Phreak kit comes with high quality anodized aluminum spacers. All screws are premium, black oxide steel. The spacers have a textured grip surface treatment, which facilitates holding of the spacers during assembly and servicing of the airframe. The spacers are 28mm tall giving you room for all the electronics to be protected inside. A silicone non-slip battery pad is included which makes an excellent platform for your LiPo battery, and helps reduce chances of a battery ejection during a crash.

Stax F4 Flight Controller Version 1.1 update!

  • Spacing for receiver pins (XM+/Crossfire Nano) is now correct!
  • 16MB onboard flash for Blackbox


The Stax Combo continues XILO's tradition of giving you high-quality FPV gear for a low price point. And it couldn't be easier to install and use on your favorite airframe!


Remove the mess of soldering and the chance of making a mistake during build time. The Stax plug n' play capability allows you to simply connect the FC and ESC with the included 8pin harness, simply wire up your motors and accessories, and you are good to go!


The F4 flight controller gives you proven rock solid processing power while the ICM20602 Gyro/Accelerometer (Up to 32KHz) gives accurate gyro information while in use. The 4-in-1 ESC uses F3 processing power to allow complex power management without a hitch. The ESC supports up to 6S input voltage while 45 amps continuous support gives you plenty of headroom to push your mini quads to the limit.


The XILO Stax FC has the unique ability to mount XM+ and Crossfire Nano style receivers directly to the FC. This saves space and makes for an overall cleaner build. If you are using a "slammed" style frame, this feature is very handy as the receiver won't add any additional height to your stack.


Another key feature on the Stax FC is the remote VTX power switch. With the XILO Stax flight controller, you are able to map a switch on your radio to turn on or off your VTX. This is useful when you are plugging in and don't want to broadcast video signal or you crashed your quad and want to prevent a roasted VTX. When a video transmitter isn't in flight it can quickly overheat due to lack of air flow, and this ability to control power can save you many burnt up VTXs.


The Stax uses standard 30.5x30.5 mounting hole configuration. The FC and ESC include M3 silicone mounting grommets to reduce vibrations to your gyro, ensuring accurate readings.


Other features such as OSD, telemetry, multiple UARTs, 5V pads, SBUS and PPM support, all come standard with the XILO Stax.


Whether you are looking for a stack for a brand new build or just freshen up an older quad, the XILO Stax will get the job done, without breaking the bank.

XILO, affordability redefined.

How to setup remote VTX power switch

The XILO Stax flight controller features a power pad for your video transmitter that can be remotely controlled via a switch setup in Betaflight. This allows you to remotely turn your VTX on or off from your radio! Simply solder your VTX to the corresponding pads on the Stax FC, (VTX, S/A, PWR, GND), the PWR pad will provide your VTX with filtered VBATT power. By default, the pad will be powered on. Go into Beta to set up a switch if you want to control power on/off remotely. You will find it under the "Modes" tab and "USER1" switch. Assign this to the AUX switch of your choice to turn the power on/off for that PWR pad. Easy!
