Ever heard of B-Unstoppable? It was the first tank drone ever built, although it hasn't quite hit the market and the design was quickly copied by a China toy maker and sold as another model. Years have passed and initial inventor and designer not only patented his project but has updated the design, tech, performance and user experience, hence the X-TankCopter was released.

Sporting a lightweight body, coreless motors and rather large 900mAh 1S LiPo battery, the whole drone weight just 131grams! From here things are getting even more interesting as the air frame will collapse from built-in pivot points to protect it from crashes, while in front of the drone we will find a 720p HD camera tied up to a WiFi digital transmitter enabling real-time FPV with the aid of the provided smartphone app.

The A100 / TRAWO is no a "new" model name, but the camera itself went through some upgrades, while on the producer site it mentions [email protected], it now records [email protected] with EIS satbilization. In the product page the specs say that it uses a Hisilicon Hi3559 chiset and a Panasonic MN34120 image sensor. During my test I've observed an above average image quality, it has very good and clear focus, has a lot of details and the [email protected] works flawlessly and it's not using double frames. Also the stabilization is extremely good and smooth whit no jerking around and no annoying image warp effects.

Here is my initial video review, i will also add more video samples later

Now this comes as a surprise, because usually when we say JJRC we expect brushed toy models and cheap prices, well not with the X7 smart model. The first things to notice are the brushless motors, dual GPS system and Full HD 1080p camera installed on a gimbal, although not yet clear of how many stabilization axes it has.

Will be available from here:

To top the specs the new X7 Smart will provided an estimated flight time up to 25 minutes by using a large 2S 2600 LiPo battery and smart flight modes such as RTH and flight plan by using a dedicated app for it.

It features a 6-Axis gyro for stable control, auto takeoff and landing, altitude hold, adjustable tilt 720P camera and last but not least an amazingly well working "Optical Flow" positioning system which doesn't need GPS satellites to work so it can be used indoors also.

The JJRC Q46 resembles the design of the Capo Ace model, while most of the technical platform is shared with the popular WLtoys 12428 series. It's a 1:12 scale 4WD desert buggy capable of "official stated" speeds of up to 45 km and it's powered by a 540 size brushed motor. Other features include real bedlock tires, working headlamps, roof rack lamps and a real working spare wheel. The only con until now is the poor battery quality as it only has ~ 1500mAh capacity and it only works for a few minutes.

My full review of the XK X520 "Fighter" is now uploaded and I must say that this thing is completely mental !

About it:
The XK X520 "Fighter" is a twin brushless motor powered aircraft fully capable of VTOL (vertical take off and landing) while still being able to fly like a regular plane for higher efficiency. To ease the control it comes with a integrated gyro flight controller that provides assisted elevon control and differential thrust. It also comes in FPV variant for more fun but it needs a special 5.8G WiFi channel band (used mostly in China).

The 2.4G remote control transmitter supports 2-way radio and will warn you for weak control signal (out of range) and battery low-voltage.
How does it perform ? You will see in the video.

The Xiaomi Drone 4K is on the market for some time now so why a such late review you may ask ? Well it's simple, people when have new tech and review it they usually are optimistic and give out biased opinions and they don't have a reliability factor taken into account. I will share my opinions and I will tell you some less known stuff and mostly the "cons" that no one is telling you.


It's a highly asked question of what version of drone to choose as it's sold in options: Chinese, USA, etc. The single difference is the bundle as the China version comes with propeller guards while the other versions come without them but it includes a WiFi dongle of which we are going to talk about later. There is also now a China version and a "China + prop guard" version, the first one has the WiFi dongle while the second one misses it.

The 2nd part of the ZOHD Nano Talon build & review series.
Be sure to check it as I'm installing and configuring the receiver, gyro and setting the failsafe on a FlySky TX&RX kit which "usually" doesn't support this safety feature. The gyro also has a big advantage as you don't need to set any kind of v-tail mixes on your TX.

Up Air One Plus 4K - Digital WiFi Edition - Full Review Part 1 (15 min 29 sec)

The test flight with the new Up Air One Plus 4K - Digital Edition is now live on YouTube. Although the drone flies flawless there are 2 things to investigate: microSD card format and size compatibility and gimbal + camera static balancing as the weight is offset currently and in some situations it will generate shake and jello.

Now this is a contradiction, named KingKong and it's only 117mm in "wheelbase", a mad racing mosquito with the name of a legendary movie character. Usually my reviews are split in two and normally first part is the one to get released initially, well this time I didn't have patience to try it and flew it directly and it was with some consequences as my setup for the flight controller was almost non existent. If you want to find more details about it you can check it here:

The Bugs 6 with FPV kit is available from HERE
Use the coupon: c80241 and get 25% OFF

The Bugs 6 (also called Bugs 8) is what MJX says it is an entry level racing quadcopter, a thing that I can only partially agree with and I will tell you why. The new Bugs 6 is a brushless 250mm class racing quadcopter with a twist, it uses just a "2S" LiPo battery, small 1806 motors and lacks acro mode, but here is where entry level ends and gets interesting as like the other "bugs" it does come with some really nice extras such as 2-way radio telemetry which will warn you about aircraft battery level and also signal strength. Beside this feature you also get a lost alarm and FPV camera modularity, you can opt for the MJX combo camera which will record 720p footage and also will output 5.8G FPV, or use the designated space to install your own system.

The build construction and design are also well thought and makes it easy to modify and service the quad, it only takes 2 seconds to pop out the top cover and have access to the internals. The propellers are also fixed on the motors with thumb friendly nuts makinging it very easy transport by taking the props off.

Eachine Goggles Two 5.8G Diversity Raceband HD 1080p FPV Goggles Review and DVR MOD


The Eachine FPV goggles are a know brand already, it's an exclusive Banggood brand and they supervise the product quality. What is nice about this way of releasing products is the fact that the seller will note the user's desires and implement them thus getting newer modeles with better functions. In this case we will have a thorough look at the Eachine Goggles Two, a FPV headset that really stands out of the crowd due to their specifications. The most important thing that i must start to specify is the type of used screen which in this case is a Full HD 1080p 5" LCD screen, taking image clarity to a whole new level. Of course you may ask why full HD when 5.8Ghz FVP is analog and has ~VGA resolution ? The answer is simple, the Eachine Two also has HDMI input thus enabling digital usage with high end devices and not only that, you can now use them with DJI quadcopter such as the Phantom 3&4, Mavic and Inspire, along with media players, tablets and even PC's making an impressive and immersive experience.

The goggles are available at a special price (currently) from the single existing provider, here:

I will start by adding the video review first as you can observe a lot of details from it and then i invite you to read more about the Eachine Two and how to mod them by adding a DVR.

The Hubsan H501SS Advanced is an updated model of the older H501S, it uses an improved circuit board and optimized firmware, actually the board is similar with the one found on the X4 Air model but it does not have the WiFi module.

This is the first part of the review where I have a in-depth bench inspection. Part 2 will come soon with flight time test, video footage, testing flight modes and more.
