Full Review of the QX105 Mini FPV Quad Racing Drone: a Small but Powerful Racing Drone

So you're curious about drones in general, maybe drone racing specifically. You've heard all the buzz about drones on social media platforms like Facebook, Twitter, or Google +. You're eager to experience the thrill of flying a racing drone. You're online reading about different beginner drones, and your budget limits yourself to buying a small or mini racing drone. In that case, the QX105 Mini FPV RTF RC quad racing drone, which comes ready-to-fly out of the box ("RTF"), might be exactly what you're looking for. Here's why.

Hybrid "H" Shaped Carbon Fibre Frame

In addition to being extra light (72.5 g with battery), the QX105 Mini FPV RTF RC quadcopter racing drone adopts a hybrid "H" shaped, carbon fibre, quadcopter (meaning it has four motors and propellers) drone racing frame configuration. With regards to the number of motors and propellers, quadcopter designs tend to be the norm in the drone industry. In addition to offering a fast and balance design, it also makes it easier to find parts and components for your drone, since most parts and components are designed with a quadcopter-type frame. What about the hybrid "H" shape frame? 
That is to say, the front propeller arms are angled like an "H" shaped frame (90°/perpendicular to the centre body), and the rear propellers are angled like an "X" shaped frame (~45° angle from the centre body). Of further note, the rear propellers arms are also noticeably shorter than the front propellers. The result of this configuration is a longer centre body that allows more space for the drone's core elements, such as the flight controller, receiver, and LED light system. In addition to facilitating maintenance, repairs, and upgrades to its core components, a longer centre drone body also allows for the 3D HD camera to be placed directly at the front of the drone, allowing for a more immersive and dynamic, in-flight, first-person-view from your drone. For a more in-depth discussion on the difference between an "H" and "X" frame, refer to our previous post on the Walkera Runner 250 PRO racing drone

Full Micro HD Camera

The QX105 UAV RTF FPV RC mini quadcopter racing drone adopts an 1/4" micro HD, 600TVL CMOS camera which, as discussed immediately above, is affixed at the very front of the drone body. A 5.8g 48 channel image transmission signal is used to transmit live/real-time video images directly to you, its pilot, for a fully immersive, dynamic, 3D augmented reality flight experience. The ultra-light (2g) red aluminum camera fixing mount allows you to adjust the camera's viewing angle (up to 120° viewing angle) according to your own personal preference.   

Propulsion System

1020 Coreless Drone Racing Motors

The QX105 UAV RTF FPV RC quadcopter racing drone incorporates four ultra-light (7.6g), small (10mm diameter, 2mm length, 1.2mm shaft diameter) but powerful black cylindrical coreless 1020 drone racing motors, with proper clockwise and counter-clock wise configuration. Coreless motors are the default choice for micro/small racing drones. They are designed to accentuate speed and acceleration. In contrast to brushed or brushless motors, typically used on small to medium-size drones, coreless motors simply mean that they are designed and built without any iron core. As small as the may be, these micro drone racing motors offer all the power and punch you need to experience the speeds of a racing drone. What is more, the QX105's drone design incorporates protective cases for the motors, a feature that greatly protects the motors from the shock/impact of landing, and that can only increase the longevity/durability of the QX105's motors. 

Dual-Blade Propellers

The QX105's mini motors propel small 2.6" (66mm), ultra-light (0.4g), black, angled (1.1" pitch), aerodynamic, dual-blade ABS (plastic) propellers. Whereas three-blade propellers tend to accentuate vertical lift, and thus, tend to be ideal for aerial photography and filming drones carrying cameras underneath their belly, dual-blade propellers tend to be ideal for forward momentum, speed, and agility. The material of the propellers is flexible, and impact resistant, a feature that tends to be most appreciated by beginners experiencing their first few flights.


Flight Controller, LED Panel, Receiver, and Transmitter

In addition to all of the above, the mini QX105 UAV RTF FPV RC quadcopter racing drone adopts as its "nerve centre" a state-of-the-art ("SoA") drone racing flight controller (Eachine AIOF3_BRUSHED Built-in OSD (STM32 F303 MCU/ MPU6000 VIA SPI Betaflight 3.0.1). For anyone unaccustomed with the terminology, a flight controller is in many sense the brain, or nerve centre of your drone that controls all of its flight operations, from its flight manoeuvres, to its LED backlight panel, to its flight modes and features (e.g. one-push 3D/360 rolls and flips). 
For instance, QX105's flight controller will sound a buzzer when either the drone the battery becomes low, or the transmission signal because weak. The Flight Controller also controls its LED light panel. As well, the Flight Controller transmits important telemetry or, flight data, via SoA 5.8GHz 48CH technology, to be displayed on your remote control screen or FPV goggles. The QX105's flight controller runs an open source firmware that has been developed by drone enthusiasts. It is regularly updated to ensure it reflects the latest in drone technology, and periodic updates can be found online. In short, the QX105's Flight Controller ensures a highly responsive, smooth, and agile flight experience. 
In addition to using a SoA flight controller, the mini QX105 UAV RTF FPV RC quadcopter racing drone also uses the latest in transmitter-receiver drone racing technology. The receiver (FlySky 8 CH receiver) is built into the flight controller. For the transmitter, the mini QX105 UAV RTF RC quadcopter racing drone uses a SoA transmitter, then i6. Like the flight controller, the i6 transmitter can be updated online, ensuring it is always up-to-date with the latest in drone technology. The i6 works on the 2.4GHz frequency range and, when binded to the receiver, is automatically assigned a unique ID. Among others, both these features ensure a clear, interference-free transmission signal between the drone and remote controller, for optimum in-flight responsiveness.
