RJX CAOS 330 FPV Race Quadcopter Frame set


The RJX  CAOS 330 Quadcopter airframe is a small yet fully functional FPV quad deserving the QAV label. The Caos 330 is a symmetric 250mm size airframe that accommodates 5" props. The 250mm is measured motor shaft to motor shaft diagonally.

The airframe is designed to support a 3s lipo setup and powerful T-Motor 2206-13 2000kv motors. 4S setups for insane flying are possible.


  • New motor mounting holes, more options for different bolt patterns
  • Thick Carbon Fiber material for the motor mounting plate
  • Flight controller cover plate includes cutouts for SMA connectors and adapters for the video transmitter.
  • Easy Lipo Access (suggested Lipo is a 3s 1300mAH Lipo)
  • Support for 32mm board cams as well as cams in cases with mounting bracket
  • Support for HD camera (such as the Mobius)

Airframe Weight : 170g

AUW: The QAV250 is flown with an AUW of around 540g (includes all flight electronics, FPV gear and Mobius HD camera).    

Vibration Free Video

Like all QAV airframes, the CAOS 330 produces vibration and jello free HD recordings. We achieve this vibration free performance with anitvibration mounts. This simplifies the small Caos 330 airframe, making it lighter, reduces parts count, and failure points.

Set Includes

  • 1x CAOS 330 airframe, board camera mount, and hardware
  • 1x Fibreglass Canopy Set
  • 5" Anti-Vibration neoprene tape
  • 1x RJX lipo strap
