GoolRC 210 UAV RTF RC FPV Quad Racing Drone: A Complete Review
The GoolRC 210 racing drone has some unique features that sets it apart from its competition, and that should catch you attention if you're online shopping to buy a medium size FPV racing drone. From the onset, what is great about the GoolRC 210 FPV racing drone is that it comes ready-to-fly out of the box, with only basic installations required. The GoolRC 210is also available for purchase at a very modest price considering its size, but also the quality of the parts and components that compose it. No special technical knowledge or expertise of drones is required to enjoy this drone. Its suitable for adults and teenagers alike, and ideal for beginners and professionals alike interested in FPV (first-person-view) drone racing. In this blog post, we review those features that make the GoolRC a unique racing drone, why we've included it among our collection of top drones, and why its worth the investment.
An "X" Shaped Frame with a Long Centre Body
A unique feature about the GoolRC 210 racing drone is that it combines an ultra-light, "X" shaped, full carbon fibre drone frame, with a long, double-plated centre body. As discussed in detail in our review of the Walkera Runner 250 PRO FPV racing drone, as well as in our review of themini QX105 FPV racing drone, drones that adopt an "X" shape drone frame configuration tend to have a much smaller centre body, which often requires stacking the drone's firmware into a vertical tower. More often than not, this also means stacking the FPV (First-Person-View) drone camera on top of the drone's stack of firmware. Such is the case of the popular Aurora mini FPV quad racing drone, for instance. As well, "X" shaped drone racing frames tend to have a closer wheelbase (distance between front and rear propulsion systems), which means that rear propellers are feeding off "recycled" air being projected from the front propellers. The GoolRC 210, however, adopts a different type of "X" shaped drone racing frame.
While keeping an "X" shaped configuration for its propellers arms, the GoolRC210 FPV racing drone adopts a prolonged centre body most often encountered with "H" shaped drone frames. In doing so, it preserves the best of both worlds. On the one hand, it preserves the enhanced acrobatic agility associated with "X" shaped frames. Unlike an "H" shaped drone racing frame where both propellers arms extended at a full 90° angle, perpendicular to the centre body of the drone, adopting an "X" shaped configuration for the propeller arms ensures a small frontal aerodynamic area, a feature that is ideal for preserving speed. By adopting a "H" shaped centre body, the GoolRC 210 also maintains more space in its centre body, providing for space to affix drone firmware. It also allows the 3D augmented reality/FPV camera to be placed directly at its nose, rather than on top of a stack of electronic components. Finally, the GoolRC 210's "H" shaped frame also makes it easier to perform routine maintenance, repairs, and even customization. In that sense, the GoolRC 210 adopts a unique, hybrid "X" shaped drone racing frame that combines the best of both worlds.
HD Video Camera
As mentioned above, the "H" shaped drone configuration of the GoolRC 210 allows its first-person-view (FPV) camera to be place directly at its front. This is in contrast to true "X" frame drone configurations, where the FPV camera is stacked on top of the drone's firmware. The GoolRC 210's camera is a 1/3" 700TVL CMOS camera. Being affixed directly at its nose, the viewing angle offered by the GoolRC 210 offers a more immersive, and dynamic view of its flight path/trajectory. Video images captured through the eye of the FPV camera are transmitted in real-time/live to your 3D virtual goggles or transmitter LCD screen using 5.8G 32CH technology for a clean, immersive, 3D virtual reality experience.
2204 2300KV Drone Racing Motors
As its propulsion system, the GoolRC 210 uses powerful, high-performance, light-weight (25g), 2204-2300KV brushless motors (32.2mm in length, 27.9mm in diameter) with maximum thrust of 440g. As mentioned in earlier post on the Walkera Runner 250 PRO, 2300KV represents the drone's RPM per volt or, the number of revolutions the motor will attempt to turn in 60 seconds when 1 kilovolt is applied, without any load attached to the motor. Although not as great as, for instance, the Walkera Runner 250 PRO, which has motors of 2500KV, 2300KV still represents a significantly high number, and is ideal for a racing or acrobatic drone. Each motor has been carefully balanced during assembly. Unique about these motors are the fact that they adopt high-quality Japanese bearings, with reduced noise, longer flight duration, and longer lifetime. It also adopts a high-efficiency Japanese spindle (0.2mm). Beginners may be content to hear the the GoolRC 210's design incorporates protective motors guards, a feature that tends to greatly prolong the longevity of a drone's motors. Better yet, the GoolRC 210 also includes landing gear with rubber pads, another protective feature that dampens the landing impact on the motors.
5045 5" Triple-Blade Propellers
The GoolRC 210's motors propel its four 5045 5 inch aerodynamic triple-blade propellers. The debate as to whether two blade propellers are better than three blade propellers still remains unsettled amongst expert drone enthusiasts. Some argue that three blade propellers offer a more stable flight, and therefore, a more stable live/real-time FPV experience. Others have argued that tri-blade propellers as being more energy-efficient, and as offering more thrust and speed. The question may well turn on a personal preference as to which type of propeller is best suited for a particular type of drone. As the GoolRC 210 is fitted with three blade propellers by default, then one can only assume three blade propellers are best suited for the GoolRC 210, until the contrary can clearly be proven. Dual-blade propellers for the GoolRC 210 racing drone are inexpensive and readily available on the markets for anyone who has a preference for dual-blade propellers.
Drone Racing Firmware
Open Source Flight Controller
The GoolRC 210 FPV racing drone uses the open source CC3D as its flight controller system. Described by drone experts as an "exceptional flight controller", the CC3D FC has been developed by drone enthusiasts from the OpenPilot community. The fact that it is an open source software ensures you're drone is always running the latest, state-of-the-art firmware. Updates can easily be found online. Overall, drone hobbyists flying a drone equipped with a CC3D flight controller, such as the GoolRC 210, can expect a clean and crisp flight experience with their drone.
The GoolRC 210 UAV RTF FPV RC quadcopter racing drone uses as its a state-of-the-art a custom transmitter, the GC6 transmitter (mode 2). The GC6 is adapted from the i6, one of the best, most popular, high-performance drone racing transmitter. The GC 6 is light and ergonomically designed, making it easy and pleasant to carry around. It features a beginner and advanced mode, making it ideal for beginners looking to experience their first drone racer. Valuable flight data, such as low battery or weak transmission signal, is displayed on a two-color 3 inch LCD screen. It adopts sophisticated radio transmission technology, features 20 different pre-programmed flight modes, as well as a long range , interference-free control distance of approximately 500 meters. Better yet, it can be used with any other compatible drone or RC airplane you may own now or in the future.
