JXD 509G 5.8G FPV RC Quadcopter 2.0MP Camera

JXD 509G Technological Features


JXD 509G quadcopter has built-in 6-Axis gyro, and 2.4G technology to adopt for anti-interference. The 5.8G Real-time 2MP camera image transmission enables players to share videos and photos to the LCD display anytime anywhere. Also the drone is designed based on wind resistance and 3D roll feature. Like many other middle-level quadcopters, JXD 509G has headless mode and built-in height setting function. 

JXD 509G Hands on Testing


Overall, a great drone for RC beginners, but you need to practice a bit if you don't have any RC drone experiences. Just press the start/stop button on the transmitter and once the drone is up in the air simply let go of the throttle lever and the drone will immediately start to hover.  If you want to come down the drone then press the start/stop button again and the motor speed will gradually decrease so drone can land softly with minimum bounce. JXD 509G is a good quadcopter with the ability to maintain altitude well. Hovering was automated and very steady. Body design is firm, so no worry about a number of crashes. The air pressure sensor allows the drone to hover at a set height, and works good in outdoor windy days. One more advice is don't forget to calibrate the drone every time before flight putting the two sticks low and centered. 

Its FPV signal is strong, but I think camera resolution could be better, but for the price, the camera is goodIn the package box a 4GB memory card is included but you better to buy more cards just in case.The flight time is around 8 minutes for a single battery charge, which is a bit shorter than that of Syma X5 series, so my advice is to buy more additional batteries. 


The remote controller is based on 4-channel mode that is very easy to use.Unlike many other entry or middle level drones, every function key, like flight speed, one-key return, headless mode and so on, of the transmitter has the corresponding function which is clearly marked. You need four AA type batteries to use the remote controller.

Skytech TK110HW Wifi FPV Foldable RC Quadcopter

Skytech TK110HW Wifi FPV Foldable RC Quadcopter



Skytech TK110HW Unpacking


The Skytech 110HW has surprising good looks, and it is among the top toy-grade drones I have tested so far. TK110HW is also very small in size, so it can be neatly held in one hand. It is also convenient for me to put it in my backpack. And for its price is not high for entry-level quadcopters. The drone is stretched in two directions, and you can see a small window through its package box. The package includes some useful accessories such as the propellers replacements, charging cable, screwdriver, remote control, phone holder and the user manual. You do not get anything extra, since it includes everything that is necessary for flight. Overall the drone is compact design.

 

Skytech TK110HW Test Fly


The drone is based on the concept of portability and Foldable, which just like DJI Mavic etc. The arms and legs of Skytech TK110HW can be folded up roughly half the width and height of the machine is reduced. And you need to download mobile application before you fly it. The overall downloading and setting-up process is easy.The drone has a standard WiFi system and is very stable to fly when I controlled it in my garden. 


Compared to other drones I have tested, like the X600 MJX, I found this SkyTech is more stable during flights. Also the Tech110HW has a height-holding function which is easy to operate. The two-speed mode setting is suitable for RC drone beginners. The battery is placed at the bottom of its main body, and you need a 850mAh type for the drone. 


Skytech TK110HW Transmitter

For me the overall body design of the remote controller is average, and you need four AA batteries to operate. The controller works well in far remote distance. You can clearly see the buttons for some features like the headless mode or automatic landing. It is easy for me to insert my mobile on the holder of the transmitter and to use it as a FPV graph transaction. Be sure you have switched on the drone before fly it. Unluckily the drone system is not applicable with Android 6.0, but works great for Android 5.0. When loaded, you get a full-featured remote controller, and it is easier to operate because every function is controlled by a separate symbol. The gravity feature brings me great fun. The camera resolution of Skytech 110HW is 0.3 MP so not so clear as some other expensive 2MP drones like the Syma X8 series.


Skytech TK110HW Conclusion


Overall Skytech 110HW is a quite unique foldable drone and it has some features which its competitors do not have: folding, height-holding, virtual remote control etc.

JJRC H31 Waterproof 2.4G Headless RC Quadcopter

JJRC H31 Waterproof 2.4G Headless RC Quadcopter

JJRC H31 Technological Features

The most important part for JJRC H31 differs from many other entry-level drones is its waterproof function, and actually, the mode is also dustproof. The body material is special, and recently I just checked a test video from JJRC supplier, the gay in the video threw the drone straightly at the cement floor and nothing happeded. This quadcopter has one key return functions like most of the RC entry-level quadcopters. Its gyro system is based on built-in 6 axis stabilizer. Also the drone got a 360-degree version for players to explore different directions during flights. For me, one of the most featured feature is its LED lights so easy for me fly during nights. Some other functions included the headless mode and over-charged protection. 


JJRC H31 Hands on Testing

For the first impression, I felt the H31 drone is very lightweight when I picked it out of the package box. Also I got a pair of free sunglassess from the package :)  Its binding takes around two seconds and is easy to control. The LED function is great and help with orientation day or night. The controller is very easy to operate for RC drone beginners. And I also got a lot help from the user manual in the package box. For outdoor fly test in low windy days, my JJRC H31 hovers overall good, stable and smooth. 

One additional battery is not enough for me so I got a second one. In low speed mode the headless mode works also good. Its controls are very responsive when I switch from low to high speed mode. When you are charging the drone, just make sure you have fully pluged in the power. Again, the drone is very strong, so its ok if you were a drone beginners and want to practice your skills. Also, it is no problem to fly in rainy days, but you need to be aware the battery part is NOT waterproof. One of the weak points I can think out is the H31 mode does not have any altitude holding function so you might have some bumps or bruises during your flights.

Original Walkera Runner 250 Advance GPS BNF Drone RC Quadcopter

Walkera Runner 250 Features Overview

The Walkera Runner 250 RC quadcopter is overall easy to disassemble and re-assemble. It is also equipped with a 800TVL HD camera, and a 5.8G real-time image transmission system. Its main body is based on CFP material design. The RC drone can realize GPS hold mode and one key return home since it has dual GPS feature. Generally the speed for the Walkera Runner 250 can be up to 40 km per hour and it can do acrobatic flights.



Walkera Runner 250 Hands on Testing

You can choose to buy a camera and VTX for the Walkera Runner 250 if you wish for FPV( first-person view). For the past several weeks I never had any flipped of deaths and I fly several full batteries continuously everytime. In case of flip of death, you just need to get some new ESC parts. I have used the RC drone to try more than 25 various types and brands rotaries. You may try to remove the lading struts for better flying experience. The Walkera Runner 250 has a "level flight" mode where it generally tries not to do something like balancing on a bar of soap in choppy water, which is very responsive and quick. My advice for practicing the Walkera RC drone is you should go out for a large open field. 

If you were still not very confident with the drone in open field, then you should try some indoor RC drones such as Hubsan H107 series first.  Well, my only complaint about this RC drone is it took me a bit longer to charge it. The GPS quality is very good, and if you landed the drone in GPS mode, you would feel great stability. The IOC feature (Intelligent Orientation Control) allows me to not think which end is the front or the back of the RC drone, so it is quite convenient. The Return to Home feature allows the drone to land where it last took off from in case of going wrong. The gimbal and camera combo are great. The gimbal holds the camera very steady. Overall, Walkera Runner 250 is a great RC quadcopter. It is some kind of racing RC drones.

Original JJRC H30C 2.4G 4CH 6 Axis Gyro RC Quadcopter

JJRC H30C Technological Features Overview

This 4-channel quadcopter JJRC H30C mode can go various directions easily such as forward, backward, up, down, turn left, or right. Its workmanship endows the RC drone with smooth and delicate design. Just like the hot sale Cheerson CX series, the JJRC H30C also has 6-Axis gyro system and 360 degree version view. You can adjust the speed mode from low to high to fit different level of RC players. The 2.0MP camera has video recording feature. The drone can be used during nights thanks for its LED light and night tracking function. You can call back to the RC drone quickly by just pressing on the automatic return option. 


JJRC H30C Hands on Testing

The size of the JJRC H30C is small and just fit in the palm of my hand. The quality is good comparable to the same kind of quadcopters. The charging time is just around 1 hour. The camera provides an acceptable clarity. I felt just a little bit noise when using it. The RC drone dropped several times already but the propellers are still working good. The flying time though is not more than 7 minutes, which is longer than any other similar brand RC mini drones. You can flip it via the remote control when flying, and it just bounces on the wall when it hit the wall but all parts are still intact. 

For RC beginners it may take sometime for first-time flying, Once its turned on, the lights flash and it connects to the remote and you can take off. Make sure you don't touch the propellers while they are moving because it hurts. Just make sure they are not bent and put them back on. This is so small that you really can't to much with it outside because of the wind, but it is perfect because of the indoors.

Walkera® MASTER CP Flybarless 6-Axis Gyro 6CH RC Helicopter with Transmitter

Walkera® MASTER RC Helicopter Features Overview

The Walkera Master CP RC Helicopter is the lastest integrated design 3D helicopter for RC beginners. It is easy to maintenance and good for 3D entrance level players to practise. The flyer has 6-axis flight control system, brushed motor and adjustable gyro sensitivity feature. 
Its transmitter, which included in the package, is based on quad-bearing design and the adopted core DEVO 12 technology. The transmitter has 2 modes: helicopter and airplane, and provides better user interface of Program MIX than past versions. 



Walkera® MASTER RC Helicopter Hands on Testing

The RC helicopter is a overall good option for RC experienced flyers who want a larger helicopter to fly outdoors. This flyer has powerful motor that transmits significant torque to large rotor blades. The original brushed motor lasted for at least 3 hours. The replacement less than 1 hour. You can easily find brushless motor accessories online. For me, it is quite fun to replace old accessories of the RC helicopter. Compared to previous Syma Helicopter models, this Master version is definitely improved. Flight times are noticeably increased. The control of the transmitter is overall easy thanks to its 7-point throttle curve. You can also update latest programs and freely sync mode data online. Well, I think the only one weakness of the RC flyer is the servos should be replaced with metal geared servos.
