DJI T600 Inspire Quadcopter

            The DJI T600 Inspire was chosen to perform aerial photography services below 400 feet. It is a quadcopter that can be purchased for approximately $2,000 dollars ready to fly and has a full motion view 4K camera mounted on a 3-axis gimbal underneath the platforms main body and four rotors (HobbyKing, 2016).  The following Figure 1 is a picture of the DJI T600 Inspire.

            The DJI T600 Inspire was designed for aerial photography and has a 360 degree field of view. The modular camera design is easily transported and upgraded if required. The 4K video and 12 megapixel photos use 720p HD and live video output. The flight is managed by advanced battery algorithms for battery life and flight management. There are specific buttons for FPV needs if required for video and photo capture. There is a gimbal control dial, HDMI and USB port allowing mobile devices to be connected, and it is also smart phone controllable. It has a one-click takeoff and landing feature with a return-to-home function also. The max flight time is approximately 18 minutes with a maximum flight altitude of 1,500 feet and weighs less than seven pounds. The following Figure 2 is a depiction of the DJI camera. The Zenmuse FC350 camera has optical flow technology, a UV filter, an anti-distortion filter, and burst shooting capabilities. The DJI T600 Inspire platform was designed for and will perform well in aerial photography at an affordable repair and operational cost.

Storm Racing Drone SRD-280

            The SRD-280 is a very stable fast FPV racer. It comes with six pre-loaded flight modes for FPV racing or practice. There is also a beginner, freestyle, and sport modes for flying in stabilized modes or acro mode for faster speeds and greater pilot control (Helipal, 2016). These six flight modes are unique to the SRD-280 making it a competitive FPV racer. It has a FPV Foxeer CMOS camera which has great image quality in all lighting with adjustments for each flying style chosen. Camera sensor placement is optimal for FPV racing on the front of the racer with tilt adjustment, smooth video quality in flight, and 75 degree FOV with real time video feeds on the FPV monitor bought separately (Helipal, 2016). It weighs approximately 500 grams, flies for approximately 20 minutes on its battery, and costs just under $400 dollars without the FPV monitor. The SRD-280 racing drone is one of the top three racing drones in popularity today and is built specifically to compete in FPV racing and drone racing events around the world (Best Drone for the Job, 2016). The following Figure 3 depicts the drone and its camera sensor placement.

  1. Jason,

    Great write up on the two vehicles. You provided a lot of great information on the two vehicles. I have always been curious about the inspire and the specifications. It does seem that this is a good platform for anyone to use. I like the fact that the camera is part of the vehicle and you do not need to buy a sensor.

  2. Great blog on the DJI Inspire and the STORM Racing DroneSRD-280. Also, DJI tends to use high-quality optic sensors for their products, and the Zenmuse FC350 has a beautiful high resolution of 4000x3000 pixels. Another great feature about the STORM Racing DroneSRD-280 is the six built-in flight modes, as this would allow the pilot to switch to the suitable flight modes on demand, and don't have to modify it via a software application. On the other hand, the Storm Racing Drone SRD-280 machine looks too "pretty" to be flying in a racing environment, where crashes are imminent.

  3. Jason,
    Great choice with the DJI T600. I think it is a testament to DJI that the majority of the class has chosen a DJI product for aerial photography. I have not seen the T600 in action and it looks like it would do a great job. The gimbal system is impressive and the prices point of $2,000 is not out of range for a small business or even personal use.
