The Anafi is a great drone for the price, but the biggest complaint I have by far is the lack of any sensors for obstacle avoidance. The only obstacle that this drone will stop you from hitting is the ground, that is, as long as you don’t hit a tree first. All of the other drones in this price range have some kind of obstacle avoidance, so why they couldn’t even add some IR sensors is beyond me.
When the AR Drone 2.0 first came out, it was one of the coolest drones for sale on the market. It has a 1GHz 32 bit processor, 1GB of ram, gyros, accelerometers, magnetometers, a pressure sensor, an ultrasonic sensor, 2 cameras and more. Even though it’s over 2 years old, the AR Drone is still one of the most advanced quadcopters available in its price range which is $299.
Drones are unmanned aerial vehicles (typically configured as quadcopters). To keep drones stable, they have on-board flight controllers capable of measuring movement, and giving feedback to the motor controllers (ESCs). Controlling the speed of each motor is what allows drones to fly in virtually any direction. For example, to move up, all the rotors spin faster creating more lift, but to move right, the left rotors spin faster and the right rotors spin slower causing the drone to tilt to the right. Once the drone is tilted to the right, some of the downward thrust is directed to the left. When a drone is hovering at an angle, it will drift in the direction that tilts in. To rotate a drone, half of the rotors spin faster and the other half spin slower. This only works because half of the rotors are spinning clockwise and the other half are spinning counterclockwise to create a torque force.
All Phantom 3 Series drones are currently available as refurbished models, which all come with full product warranties. The Phantom 3 Standard offers a stabilized 3-axis gimbal and up to 2.7K video shooting. It also features Lightbridge digital streaming, which allows live viewing at up to of 720p. The refurbished version is available for just $399, which is a great, affordable drone for hobbyists.
It has a built-in positioning system which allows for ONE-KEY RETURN. If you’re flying outside and happen to loose track of it, just push one button on the remote and it will return to the remote. Well… it will return sometimes. Like all of the other toy drones, ONE-KEY RETURN doesn’t really work that well since there’s no GPS onboard, but it will send the quad back in your general direction which is cool.
For the power system, it has Lumenier RX2206-11 2350Kv motors and Lumenier 30A BLHeli_S ESCs with DSHOT Multishot and all of the other high-speed communication protocols you need. The flight controller is a MPU6000, STM32F405 (what a mouth full!). Basically, it’s a clone of a flight controller called the REVO that originally cost over $100 to make and had a super fast F4 processor. The FPV system is nothing that will blow you away like on the Falcore drone. It’s just your standard 200mW 5.8GHz Raceband TX and 600TVL camera, but it gets the job done for pro pilots, so I guess we can’t complain!
There isn’t much that the Inspire 2 CAN’T do. It comes standard with all of the features of the Phantom 4 Professional, but with a design optimized for performance and industry leading video features. It’s almost twice as big and twice as fast as the Phantom 4 (reaching speeds of almost 60MPH), and with it’s transforming design, the propellers will hardly ever appear in your videos. Additionally, the Inspire 2 comes with a dedicated FPV (first-person-view) camera so you can see where your flying at all times. With all of these features, you no longer have to blindly fly backward or sideways to get the shots you want.
