DJI Phantom 4 Pro Repair

Phantom is a series of UAVs (or unmanned aerial vehicles) designed and manufactured by DJI, a Chinese technology company. The Phantom 4 Pro was released in November 2016, several months after the Phantom 4 was released in March 2016. The Phantom 4 Pro is the professional version of the fourth generation of the Phantom UAV series.

The Phantom 4 Pro includes a three-axis (yaw, pitch, roll) stabilized camera and a 1-inch 20-megapixel CMOS (complementary metal-oxide-semiconductor) sensor. Compared to the Phantom 4, the Pro has upgraded obstacle avoidance that features five directional sensors. The Phantom 4 Pro also includes two remote controllers (one controller with a dedicated screen for the Phantom 4 Pro+ and one controller without a screen).

The Phantom 4 Pro includes a 5870 mAh “Intelligent Flight Battery” that produces 89.2 Watt-hours of energy. The remote controller includes a 6000 mAg battery. The Pro can be operated from up to 7 kilometers (or about 4.3 miles) in certain modes and under certain circumstances. The Pro is able to take a wider variety of photographs and videos than the original Phantom 4. The Pro also has an improved obstacle sensory range of 2 to 98 feet when compared to the 4’s 2- to 48-foot obstacle sensory range.

The Phantom 4 Pro can be identified by its white quadcopter body and the name “Phantom” in capital letters above the great camera gimbal.
