Our Quadcopter WiFi HD Camera Drone are Remote Control Flying Devices which are used in the various field such as inspections, Construction Sites, Security, Agriculture, Search & Rescue, Aerial Photography in Wedding & Events, Land Surveying, Geographic Mapping, Wildlife Monitoring, Law-Enforcement, border patrol, Military Uses and You can Also use them for Fun.

There are different-different types of Drone according to your requirement or knowledge level. The purpose of your Quadcopter WiFi HD Camera Drone propellers is to generate thrust and torque to keep your drone flying, and to maneuver. The upward thrust force generated by the propellers is usually measured in pounds or grams.

To keep your Quadcopter WiFi HD Camera Drone flying at a hover, the upward thrust needs to equal the weight of your drone. The thrust to weight ratio TWR (thrust divided by weight), indicates how much thrust your drone generates relative to its weight. A good rule of thumb is to design the TWR to be at least a value of two.

The Quadcopter WiFi HD Camera Drone propeller pitch is a measurement of how far that a propeller will move through the air for every single rotation of the motor/propeller. This is only a theoretical approximation since real world factors such as prop material, air density, and efficiency can influence this distance. However, the pitch is a good measurement that will help you better understand your propeller performance.
