After reading this detailed introduction, what do you think of this backpack?

If interested please don’t hesitate to join in the pre-order now.


Betaflight Hive Backpack, pre-order now!

Good news for fpv racers here. FPVMODEL has promoted new fpv backpack which has authorized by Betaflight, called Betaflight Hive Backpack.


This is the appearance of it. Curious about it ?

The design of the Betaflight Backpack has been going over for several months now and have finally settled on the final prototype.

While we were designing the Betaflight backpack one thing kept coming up in the design aspect was how much room the transmitter took up inside the bag. So, we thought the best design would be to make a hard shell top mounted case on the top of the bag. The hard shell top of the case allows for extra protection of your transmitter and frees up valuable space inside the bag.


The interior of the bag is very similar to other DSLR style camera bags and allows for multiple design layouts by using cushioned dividers that velcro in place and let each user layout their own custom setup based on their specific needs. The exterior of the bag has multiple strap points that are adjustable in height separation by plastic strap connectors the move up and down on a rail seam at the outside edges of the hard shell cover that allow for multiple quads to be strapped to the bag, freeing even more space for tools and accessories on the interior of the Betaflight Backpack, but there is also room on the inside if you prefer to carry your quads in the bag.


For more interior shape and inner space, please check it here:

Now the Betaflight Hive Backpack is on pre-order now. During pre-order you can purchase it at a lower price and once pre-order ends the price may be higher. Just hurry up!!!

X-Racer KL-EX90 Micro Racing Quad, a light frame built for micro class FPV racing

Belong to series X-3Racer, KL-EX90 micro racing quad is another mini quad for FPV racing. Unlike the former X-Racer X-1 mainly designed for first users and children, KL-EX90 is one professional frame,  a 2″ propeller 90 class airframe for micro class FPV racing.

It weights 106 grams with a  2S 550mAh lipo battery. One important thing lies here: in terms of its small in size and light weight under 250g, you do not need to register with FAA if you are from the United States to fly the KL-EX90.

Compact design, suitable for both indoor and outdoor FPV. Equipped with F3 Flight Controller, 4-in-1 ESC,  powerful 1105-7500kv motors, Runcam Micro Swift FPV camera, Dragonfly 25mw 48ch vTX and LED light, all these have made the KL-EX90 perfect for both LOS and FPV flyers.

KL-EX90 uses reputable Flycolor RAPTOR S-Tower of F3 FC and 4-in-1 BLHeli_S 2-3S ESC gives you extremely good stability and flight performance.

Use Runcam Micro Swift, the worlds smallest and lightest CCD professional camera. It has the same performance to the well-known Runcam Swift and Swift Mini.

Worried about it may be hurtful and violent?

No worry!  Look! They also wear protection cover. It may reduce damage to your KL-EX90 in case of a hard crash.


  • Small in size and light in weight. All-up-weight is 106 grams only with a 2S 550mAh lipo battery. Do not require the hassles of getting it registered with the FAA if you are from the United States.
  • 2s / 3s lipo. Excellent power with just a 2S battery, even more powerful with 3S. It gives you very high speed, very precise and rail-like handling.
  • Fast as other larger racing quads. Our team pilot Ka Kei Leung finished the drone race at WMC 2017 in 9.65 sec.
  • Use Runcam Micro Swift, the worlds smallest and lightest CCD professional camera. It has the same performance to reputable Runcam Swift and Swift Mini.
  • The reputable Flycolor RAPTOR S-Tower of F3 FC and 4-in-1 BLHeli_S 2-3S ESC gives you extremely good stability and flight performance.
  • Equipped with powerful micro Dragonfly MC1105 brushless motors. Works great with Gemfan BN2035 propellers and Flycolor RAPTOR S-Tower.
  • A Dragonfly 25mw 48ch Vtx with protective coating is inlcuded to give an even more aero dynamic low profile design for the video transmission.
  • The flight controller is with built-in OSD.
  • The design is inspired by the champion KL200Race racing drone. Much smaller in size, but gives you the same flying experience of professional 200 and 210 class racing drones.



X-Racer Quadrant BLHeli_32 ESC:25A or 35A, what’s your choice?

Now in the quadcopter industry, BLHeli_32 has gain much attention.BLHeli_32 is the 3rd generation of BLHeli firmware after BLHeli and BLHeli_S. BLHeli_32 runs on an ARM 32bit MCU, initially it will be on a Cortex-M0 running at 48MHz, but there are MCUs out there that can run a lot faster.

Benefit from the Dshot 1200 and BLHeli_32 firmware,  several BLHeli_32 ESCs have earned more popularity.

Today we focus on the new X-Racer Quadrant 32Bit BLHeli_32 ESC. There are two categories: 25A and 35A. Both of them follow the design of previous 4-in-1 design of X-Racer Quadrant. It is not a single board, but four tiny ESCs can be installed separately on the arms, or installed together like a PCB under the flight controller.

X-Racer Quadrant 2-6S 32Bit BLHeli_32 ESCs:

  • With 25AMp constant RMS, 30A max.
  • Less than 3 grams each piece and about 11.5 grams for a set of 4 pieces.
  • Small in size: 18 x 24mm
  • Compatible to BetaflightF3 Flight Controller

The new X-Racer Quadrant 25A is flashed with the latest BLHeli_32 program. Dshot up to at least Dshot1200, and at rates up to at least 32kHz is now supported.

The new X-Racer Quadrant 35A is also flashed with the latest BLHeli_32 program. Dshot up to at least Dshot1200, and at rates up to at least 32kHz is now supported.

  • Rated at 35A current with a max of 50 amps of current load (Less than 10s).
  • Small in size: 20 x 24mm
  • 3 grams each piece and about 12 grams for a set of 4 pieces.
  • Compatible to BetaflightF3 Flight Controller

Also these two ESCs have other common features:

  • Use the latest BLHeli_32 firmware.
  • Dshot up to at least Dshot1200.
  • At rates up to at least 32kHz is supported.
  • Four tiny ESCs can be installed separately on the arms, or installed together like a PCB under the flight controller.
  • 2-6s Lipo input.



2017 Drone Racing League Season have started on June 20th

After what has seemed like a long wait, the Drone Racing League’s (DRL) second season is due to air this evening. Plenty has happened behind the scenes at the company since its immersive action was last on TV. Here’s hoping that all the changes front of house are for the better.

With all the excitement at DRL away from the track, which has included lucrative partnerships with the likes of Amazon and Allianz and big broadcasting deals with ESPN and Sky, it’s now time to focus on the action.

The 2017 DRL season is made up of six races. Featuring original, three-dimensional racecourses, the new season will play out at several iconic venues around the world. 16 of the world’s best drone pilots have been invited to fly DRL’s custom fleet of 600 Racer3 drones.

The season will air as 16 one-hour episodes beginning on ESPN 2 at 8pm EST. It’ll also be broadcast in more than 75 countries around the world on networks including Sky Sports, ProsiebenSat.1 7MAXX, Disney XD and OSN.

“The 2017 DRL season brings the world’s greatest drone pilots to the most incredible race courses ever designed, testing pilot skill and pushing the custom DRL drone, theRacer3, to high speed crashes and split second finishes,” said DRL CEO and Founder Nicholas Horbaczewski.

“Right from the start, this season will capture the imagination of traditional and new race fans around the world.”

DRL Drone racing league season 2

One track that’s survived from the first season is Level 1: Miami Nights. It’ll be the opener, taking place at the Hard Rock Stadium, home to the Miami Dolphins.

DRL has promised that the 2017 season will progress “to more unique venues, with dramatic vertical lines and new obstacles to test pilots’ skills, and push the limit of the Racer3.”

After Miami, the 2017 season moves on to Atlanta, New Orleans, Boston, and Munich, culminating in the World Championship in London, set in the historic Alexandra Palace.

What is BLHeli_32?

BLHeli_32 is a new firmware for 32 bit ESCs that has recently been announced by Steffen, the contributor for the original BLHeli and BLHeli_S projects.

Its worth noting that despite the fact it shares the name with its BLHeli counterparts, the code is in fact written from scratch and is closed source. This means the code will not be released to the community, similar to how the KISS ESC code is not released.

This firmware should bring significant improvements to ESC performance at the moment, compared to BLHeli_S. Here are a few of the advantages:

  • Programmable pwm frequency, up to 48kHz, that can run motors even smoother, and also allows for moving of small but potentially disturbing humps in the throttle response. All ESCs have these bumps, with BLHeli_32 they can now be moved in the rpm range, to a place where the system has low sensitivity to them.
  • Auto timing. Which is not the option to choose if you’re after max power. But if you want the most efficient running with very good robustness against desync, it is the perfect choice.
  • Voltage and current limiting. Which is implemented in the code, and will be supported on some ESCs. Voltage limiting is desirable for fixed wing crafts. And current limiting adds protection against ESC failure.
  • Programmable brake on stop force. Which allows control of the braking of fixed wing props.
  • Improved direction change in bidirectional mode.
  • More functionality coming in the future. Such as setup from the FC by using Dshot commands. Such as telemetry functionality. There is room to grow performance and functionality.
  • Runs D-Shot 1200 straight out of the box (up to at least a rate of 32kHz supported)

Top 5 Best Flight Controllers in March 2017 by Oscar Liang

Lately the flight controllers featured here are chosen because they scored top votes through facebook group poll by Oscar Liang.

The choice of FC really depends on which firmware you prefer to run. Some FC might be compatible with more than one firmware, but the FC recommendation might change from one firmware to another.

Common features the listed FC’s have:

  • F3 or F4 CPU
  • Low noise gyro with SPI Bus allow up to 8K Gyro sample rate – such as MPU6000
  • Boards designed for Betaflight tend to have SD card logger for blackbox

Betaflight F3 (FPVModel)

Betaflight F3 Flight controller (BFF3) is designed by FPVModel with co-operation of Boris B.(Betaflight creator and developer). It was made to support all Betaflight features in one single board. The BFF3 came flashed with Betaflight 3.1 firmware.


  • F3 Processor
  • MPU6000 Gyro/ACC Sensor
  • 3 x UART ports (one for radio receiver)
  • Built in 3A 5V BEC
  • Built in OSD – configurable via Betaflight GUI
  • SD Card adapter for BlackBox
  • Current sensor
  • Power distribution board with six-layer PCB
  • Weights 8.6g

Designed specifically for Betaflight, by Betaflight founder Boris B, this board is packed with features that you need to unlock all the potential of BF.

Designed specifically for Betaflight, by Betaflight founder Boris B, this board is packed with features that you need to unlock all the potential of BF. The BFF3 built-in OSD is much easier to use than MinimOSD, all configuration can be done in the configurator. You can even tune your rates and PID with OSD. If you don’t need the OSD you can simply bypass it.

This board acts like a hub for all your components, ESC, VTX, camera, RX, LiPo battery can all connect directly to this board. This allows a really compact, simple and “single board” racing drone build.

Revolt F4 (Raceflight)

  • F4 Processor, Invensense 20602 Gyro/Acc
  • Designed for Raceflight

The Revolt F4 FC is designed specifically for Raceflight by the Raceflight team. It allows the fastest gyro refresh rate, PID looptime of up to 32khz. Some disagree with the “faster is better” concept, but many users have expressed positive feedback regarding performance of Revolt F4 running Raceflight. Their latest software “RF1” (Raceflight One) also continues to develop and makes setting up easier for users.

The Revolt F4 is a simple FC without any bells and whistles. Not even an on-board 5V BEC, which means you will need an external 5V power supply for this FC (and an additional VBAT connection to monitor LiPo voltage). RF team explains this is to keep the noise down.

By the way, the Lumenier Skitzo FC is a rebrand of Revolt, they are the same board except the colour and price.

Kiss FC

  • F3 Processor, MPU6050 Gyro
  • Comes with KISS FC firmware, supports Betaflight

Probably the longest-standing flight controller in this list, the KISS FC was released back in Dec 2015. I think the main reason for its lasting popularity is Flyduino’s closed source KISS FC firmware, which is exclusive to the KISS FC.

The KISS offers easy setup and very unique flight characteristics. I personally found KISS flies a bit smoother and softer while Betaflight flies more precise but more robotic. Not really the most accurate description, but this is the best way I could put it.

It’s one of the first controller boards that came up with “H” shape with solder pads because most of us like direct soldering. However I found the ESC pin layout not very user-friendly: they are all located on one side, on both top and bottom of the board.

The Kiss FC also supports Betaflight firmware, but in my opinion there are better F3 FC out there for Betaflight. The main reason for KISS FC is really just the firmware.

Omnibus F4 Pro

  • F4 Processor, MPU6000
  • Supports Betaflight
  • SD card logger for blackbox
  • OSD built-in
  • Integrated Current Sensor
  • Built-in Barometer – BMP28

The Omnibus F4 has Betaflight OSD that allows you to change PID/rates with your sticks, and built-in current sensor provides information about current draw and mAh used. This FC can take 4S power directly from battery as it has a inbuilt 5V BEC. However it does not have PDB capability like the Betaflight F3, which means you will need to run a separate PDB for your ESC’s.

One thing to be aware of with F4 FC’s is the trouble running Smart Port telemetry, because S.Port signal is inverted from X4R/XSR receivers, and F4 does not natively support UART inverting. Normally you need an external inverter, or hack your receiver to get uninverted S.Port signal.


  • F3 MCU, MPU6000
  • Betaflight firmware
  • In-built SD card logger for blackbox
  • 5V/3.3V 1A selectable BEC

If you need a plain and simple FC to run Betaflight, the Lux F3 v2 might be a good option for you.

If you need a plain and simple FC to run Betaflight, the Lux F3 V2 might be a good option for you. The V2 was improved from the previous version with a better Gyro, and a few other features. It has a very practical and ESC pad layout (at the 4 corners), and the board takes up to 6S LiPo input.

After introducing these flitht controllers, what’s your opinion about it?

What’s the future of drones? Have you ever imagined yet?

What is the Future of Drones?

No doubt that drones are playing a key role in our world over the next few decades but what are these versatile machines truly capable of? Drones have already become part of our society as we speak. These are the unmanned vehicles or remote controlled drones hovering over our skies either used for recreational or military purposes. We have also seen drones being used not only in military operations but through filmmaking, photography and other recreational purposes. This begs the question on what the future lies ahead for drones. Here are some insights and predictions on the future of drones.

  • Delivery drones  

Back in 2013, Amazon announced that they plan to use delivey drones. It sounds a take from a science fiction flick, but Amazon is serious about it. They are still conducting test runs and experiments as we speak to ensure satety and reliability of the project. This is one bold move to integrate the capabilities of using drones to the courier industry.

  • Search and rescue drones

Drones can be used for search and rescue operations. They can be used in dangerous terrain, extreme temperatures, and fatal radiation levels. Drones are’t limited to flying gadgets. There’s a big opportunity for innovation for underwater and land drones. Drones can be used to find survivors from shipwrecks. Small drones that are capable in creeping through crevices of collapsed buildings or houses can also be used by rescue teams.

  • Ambulance drones

In development, ambulance drones are  capable of airlifting injured individuals to safety or to nearby hospitals so that medical attention can be given to them immediately. Ambulance drones can be used for disaster relief, military and police operations, and for remote places where medical care is scarce.

  • Drones for space exploration

Not saying that rovers would be obsolete, but using drones to explore and gather data from space exploration is not a bad idea. By using drones that are properly configured to fly in accordance to a plane’s gravitational pull; we can now explore mountains and volcanoes of different planets that the rover would be unable to reach. This also goes with drones for underwater exploaation of one fo Jupiter’s moon, Europe. In development is a squid-like drone that is able to maneuver itself in Europa’s lakes and oceans.

  • Police operations

Drones can be used for legitimate police operations. They won’t be equipped with machine guns, but they’ll be able to help the police catch the bad guys. Equipped with higy definition cameras, night vision and thermal sensors, these drones can be used for surveillance to aid the police in their flight against crime.

  • Construction drones

Soon there will be drones that can be used to help in the construction of high-rise buildings. These drones can also be used to conduct surveying and mapping for a certain project. This helps architects and engineers to hasten the process of surveying the project site while the drone sends data to them in real time. These drones can also be used in high-risk areas that are difficult to reach by a human team. This will greatly benefit surveyors and the construction industy in general, as it would save time and effort in gathering information before a project goes green.

  • Faster drones

There have been more and more manufacturers of drones like DJI, GoPro, and YI Technology, but the one from YI Technology claimed they are the fastest tri-copter drone compared to others. They said it can run speeds up to 75 miles per hour(120 km/h) equipped with a gimbal and anaction camera. Made of carbon fiber, unlike others that are made from lightweight aluminum and alloys.

With a rise of sales in commercial drones, expect manufacturers to improve their product to make them easier to control and for their drones to have improved strength, handling, and maneuverability. With different innovations and improvement in drone technology, expect more opportunities for drones to be used in our everyday life. Just like how the saying goes “The sky’s the limit.
