  • Caddx Polar Vista Kit provides a premium and lightweight HD FPV camera system with a large wide camera angle, 162°. With video clarity and transmission intensity comparable to the DJI Air Unit, and enhanced night vision. Pilots can give full credit to the high-quality image connection under any circumstances. GoPro can be also equipped on this quadcopter.
  • HQ and Gemfan 3520 3-blade propellers are both put in the package. They are capable of providing linear throttle response in the flight time and control efficiency suite. With 3.5-inch props, the X-Knight 35 has enough lift power while performing a variety of freestyle and acrobatic flying tricks perfectly and efficiently. Besides, it is less noisy than those 5-inch props quads.
  • The unique frame design makes it suitable for photography, the lens position is forward with a protective shell. You don't have to worry about seeing the props or the frame itself in the flight video, which is great for making cinematic shots and vlogging.
  • Equipped with an F4 AIO 20A and 1404-3800KV motor, this great combination of power systems enables the X-Knight 35 to maintain magnificent energy and less noise in flight.
