If you're looking to buy a great FVP racing drone, consider buying the Furious 215 FPV racing quadcopter drone by Walkera. The Furious 215 is agile, crash proof, easy to maintain, repair, and fine tune. In addition to its micro HD camera, its secondary camera mount offers room for an extra optional camera of your choice.
Furious 215 Hybrid "X" Drone Design: Crash-Proof + Agile
"X" Configured Propeller Arms
The Furious 215 FPV racing quadcopter drone adopts a robust, high strength, 4mm hybrid "X" drone racing body frame. While its propeller arms are configured as an "X" shape, its central body adopts an "H" type drone body. Hybrid "X" and "H" frames tend to offer the best of both worlds. With respect to the Furious 215 FPV racing quad drone, the "X" configured propeller arms offer that advantage of greater agility when performing tight in-flight manoeuvres like turns, flips, and rolls. "X" shaped propeller arms also tend to have a stable centre of gravity, often contributing towards a well-balanced flight experience. As discussed in previous drone reviews, with "X" configured propeller arms, as opposed to "H" configured propeller arms, less propeller arm surface is exposed to the incoming airflow, and less drag is created. Unique about the Furious 215's propeller arms is the fact that they can easily be snapped on and off from the main, centre body. In cast of a crash, the result is detached propeller arms, rather than broken propeller arms requiring full replacement.
"H" Centre Drone Body: More 'Real Estate'
Not all drones with "X" configured drone propeller arms opt for an "H" type centre drone body. This usually tends to be a matter of size. The mini Aurora FPV quad racing drone is one example of a true "X" shaped quadcopter drone design which, due to its size, opts for a compact "X" type centre body. With a long but compact rectangular "H" type drone centre body, the Furious 215 has the advantage of offering larger "real estate" space to install critical parts and components. "H" type centre drone bodies also tend to have a cleaner, orderly, coherent layout for its critical parts and components, often facilitating maintenance, repairs, tuning, and customization.
Protective Motor Guards and Landing Gear
Other advantages offered by the Furious 215's drone design include protective motor guards on all fours. Not all racing drones offer this advantage (consider, for instance, the Racer 130 FPV racing quad drone). Combined with landing gear that dampen the impact of landing, these features can greatly enhance the durability of a drone's motors. The Furious 215 also adopts a robust, compact, two-layered centre body design. The two plates are secured one on top of the other with solid, reinforcing aluminum alloy and metal posts and screws. While the Furious 215's centre body design doesn't adopt protective walls protecting its centre components from left and right, as with the drone design adopted by the Wizard x220 racing drone, for instance, the top-bottom layers offer ample protection to Furious 215's critical 'organs'. A better finishing on the sides would arguably improve airflow performance around the Furious 215's centre body.
Protective Camera Casing + Secondary Camera Mount
Also apparent from the Furious 215's drone body design is the incorporation of a solid, robust, protective, and adjustable, full carbon fibre camera casing affixed to the base of the Furious 215's main body by two metal posts. Three reinforcing screws at the top and bottom of the adjustable camera mount, in addition to reinforcing the camera mount structure, serve to dissipate the shock of impact and crashes away from the camera. The top layer of that extends into the main drone body can also be used as a secondary camera mount to rest a second camera (e.g. GoPro). Naturally, the second camera laying on top of the second plate will not benefit from the same protection offered to the built-in camera.
Furious 215 Micro HD Camera: 130° FOV, 1.5km Transmission Distance, and Much More
If you're looking to buy a drone with HD camera that offers a highly immersive, dynamic, first-person-view ('FPV') experience, the Furious 215 has everything you need. In addition to the above-mentioned secondary camera mount, the Furious 215 incorporates by design a micro HD 600TVL camera that performs exceptionally well under lowlight conditions. The Furious 215's built-in HD Camera offers a lens of focus of 2.5mm, with a horizontal field of view of 130°, which is broader than what is typically offered by a standard pair of binoculars (114°). The Furious 215 also comes with state-of-the-art ('SoA'), high-performance, video transmission technology for a fluid, live/real-time video streaming experience. A high-end HG omni-directional mushroom antenna offers an astonishing transmission distances of up to 1.5km.
Furious 215 Propulsion System
High-Performance 2500KV Brushless Motors
The Furious 215 FPV racing quadcopter drone adopts as its driving force high-performance 2500KV brushless drone racing motors. With the standard driving force of racing drones being in the 2300KV range, the Furious 215 FPV racing quad drone has more power than necessary to bring you ahead of the competition. As brushless motors do not incorporate "brushes" in their design, brushless motors also tend to require less maintenance, and also tend to offer a longer lifespan. Their durability is further enhanced by the aforementioned advantages of protective motors guards, as well as landing pads underneath each motor to dampen the impact of landing.
BLHeli ESCs w/ Oneshot 42 and Oneshot 125 Protocol: Smooth and Responsive Speed, Acceleration, and Breaking
Electronic speed controllers ('ESCs') serve to regulate, in a smooth and responsive manner, the speed and direction of each motors. They also serve as a dynamic break. The Furious 215 uses the highly popular BLHeli ESCs with Oneshot 42 and Oneshot 125, which are both special modes to run the BLHeli firmware that allows its supported flight controller to communicate quickly with its ESCs. This allows the motors to react much faster than standard pulse width modulation ('PMW') communication protocols used on most ESCs. In short, the Furious 215's ESCs help provide smooth and responsive control over the Furious 215's acceleration, speed, and breaking.
Three-Blade 5" Propellers for Extra Traction, Forward Momentum, and Speed
The Furious 215's competitive drone racing motors propel 5040 5" aerodynamic three-blade drone racing propellers. In contrast to double-blade propellers, three-blade propellers, such as those sported by the Furious 215, tend to be heavier, consume slightly more battery energy, and are less agile. However, they also generate more thrust, forward momentum, traction, and speed. It may be telling that the Drone Racing League (DRL) Racer3 FPV racing drone appears to be fitted with three-blade propellers. As with most drones, the flying the Furious 215 with either three or two-blade propellers is a question of personal preference. Compatible two-blade drone racing propellers can easily be purchased on the market, and fitted on the Furious 215.
Mainstream F3 Flight Controller
Flight Controllers ('FC') Explained
What is a drone flight controller? A drone flight controller is to a drone as the nervous system is to the human body. Flight controllers are a small circuit board that contain a variety of different flight systems and sensors that generate a constant stream of in-flight data sets which, when combined, help determine the drone's altitude, speed, orientation changes, and much more. Available sensors vary from one drone to another. They include GPS, LED lights, sonar sensor, barometric pressure sensors, magnetometer (compass), airspeed sensors, accelerometers, gyroscopes, accelerometer, and more. A drone's flight controller also receives commands from the receiver, which receives its commands from the drone's remote control/transmitter. What Flight Controller does the Furious 215 racing drone use?
Furious 215's F3 FC
The Furious 215 UAV FPV RC quadcopter racing drone uses the popular, mainstream F3 flight controller with integrated power distribution board ('PDB'). This last feature allows the Flight Controller to be powered by lithium polymer ('LiPo') battery directly. The F3 flight controller is essentially the third series of the STM32 processor, a 32-bit micro controller integrated circuit. Among other things, the F3 flight controller has, in contrast to its predecessor F1 and F2 :
- Faster floating point calculation;
- 1 additional UART (hardware serial port/an individual integrated circuit ('CI') used for communications);
- Dedicated USB port; ability to run SBUS and Smart Port directly; and
- Faster loop time (4k).
The F3 flight controller can easily be fine-tuned to suit your own preference over flight performance. The Furious 215 UAV RTF FPV RC quadcopter drone is also equipped with Boot Key, which also easily allows you to upgrade the BetaFlight, CleanFlight, and SPRacing F3 Firmware. Overall, the Furious 215 is equipped with a state-of-the-art Flight Controller that offers all that is best in the latest of drone flight controllers. The end result is a high-performance, pleasant, stable, responsive, and fast drone racing flight experience.
The Furious 215 UAV RTF FPV RC quadcopter racing drone uses as its transmitter a state-of-the-art drone remote control/transmitter that is, the Devo 7. The Devo7 functions on 7 channel 2.4GHz technology, the latest standard of the new generation radio system. Among many other things, it offers a long range transmission distance, minimal interference, and stable radio transmission. In addition to being able to store up to 15 model memories (you can use your Devo7 transmitter with up to 15 different drones), it also features granular control over throttle and pitch, 3 flight modes (Normal, IDLE 1, IDLE 2), Dual Rate (DR) and EXP settings, Servo reverse, Swash plate mode, gyro sensitivity, and much more.
