    This tiny quadcopter actually has brushless motors that give it more than enough power (maybe too much ;-) Buy it here https://goo.gl/qT1VU8 Although powerful, it’s still fully suitable and safe for indoor or outdoor FPV flying in the park.

    Pros
    - Very powerful brushless ducted fan quadcopter. Very fast for a ducted fan quadcopter.
    - Available versions include DSM/Frsky/Flysky (AFHDS2A).
    - Omnibus F3 FCB loaded with Betaflight 3.1.0
    - 600 TVL camera with 25 mW 48 Channel NTSC/PAL FPV transmitter
    - Built-in On Screen Display (OSD), configurable in Betaflight (note the name in the lower left corner of the display ;-) .
    - 7500 kV brushless motors with 10A BLHELI_S Dshot 4in1 ESC
    - Powered by 7.4V 450mah 80C LiPo
    - All electronics well protected in composite central structure
    - Supporting structure and ducting are aluminum and composite. Very tough.
    - Suitable for indoor or outdoor use.
    - Does not require FAA registration.

    Cons
    - Propeller blades are somewhat brittle, and might fail if excessive power is applied.
    - AIO FPV camera lightly held in place by small strip of velcro.
    - Receiver antenna just a floppy wire. You’ll definitely need to velcro it up and out of the way of the props.
