Power Meter V2

Immersion RC’s Power Meter V2

The time arrived for a new article. The ImmersionRC’s Power Meter V2 has been on people’s radar for a while now, announced around December 2017 and shipped in March 2018. We have them now in stock at NGhobbies, and you can order them by clicking on the image below. Powermeter V2

Looking back at the first version of the power meter, which was a bit bulky and required an external power source, the second version is definitely slimmer and smaller, includes a battery as well which makes it very nice portable design. Almost to the point where you would be afraid that if you put it down you’ll not find it again on the mess on your workbench 🙂

All that said, if is definitely a huge improvement to the previous design not only for the looks but for the functionality as well. In today’s most organized races the race director usually checks every racing quad before it allows them on the flight line to make sure they all comply with the power requirements of the race. If it is a 25mW race, then all quads should read under 25-30mW power output, or if it is a 200mW race, then all participants racing machines should provide a power output less than 200, but also more than 150mW.  This tool helps pilots and race directors to achieve equal terms when racing, no one would have the advantage of higher power output compared to others – also assuring that no higher output can wide out the video signal for any of the other racers.

In lack of the manual – which at the time of this writing has not yet been released by Immersion, we will try to quickly present you the 3 operating modes of the Power Meter V2:

  • Measuring mode: In this mode – once it is calibrated to a reference signal – you can precisely measure the power output of a transmitter in “dbm” or “mW”. If no output is detected, the display shows uW values which translate to “”micro Watts”. As you can see the frequency is shown in the bottom left corner, the frequency can be changed from the menu by pushing the 4 way button in. Available frequencies are: 35, 72, 433, 868, 900, 1200, 2400, 5600, 5650, 5700, 5750, 5800, 5850, 5900, 5950, 6000Mhz. You will jsut need to select the frequency you are transmitting closest to, no need for exact frequency selection.  The top left displays the battery charge level, the top right indicates id the power meter is in “peak” or “average” measuring mode – also adjustable from the built in menu. The bar graph on the bottom indicates the signal level as well expressed in percentage.
  • Packet Analyzer Mode: In this mode your power meter looks packets of data, PWM signal or similar on the selected frequencies. If you move this close to a remote control transmitter or a WiFi router, then you can see the packet data flowing on the screen. Pushing the 4 way button up/down will change the span value, meaning it will take more or less readings per second.
  • Scully Mode: This is the race director mode which will allow a race director to do a “Pass”/”Fail” test of the racing quads. This mode will show if any of the quads are above or below the desired signal level. In this mode when the Power Meter is calibrated to a specific signal level, it will compare the incoming signal to that stored level. With that, if your transmitter is under the middle bar, then you are not overpowered and you can fly – just like in the picture below, if it is above the line you are above the power level allowed for that specific race.

In either mode this device will need a little work to be able to measure precisely. We prepared a video for you to watch on how to do that, see it below:

Joe Scully spent some time preparing a video on how to use the same RF Power Meter in Race Director mode, please watch it below:

I hope you will find these instructions useful when using the RF Power Meter V2 from Immersion RC.

Fat Shark 101 – Drone Training System

On December 21st, 2017 Fat Shark announced that their new Drone Training system is now available for pre-order and will start shipping them in January. This is a revolutionary news, because with this move Fat Shark reached out to all masses who want to get into flying little racing drones they can do it now without a huge start-up expense.

Fat Shark 101 Kit The Fat Shark 101 – Drone Training System – as they call it comes with everything in the package what is required to start flying drones FPV.  Starting with the custom engineered 107mm (diagonal motor to motor distance) Sharky done, a custom design FlySky compatible 6 channel remote controller, a brand new design, very comfortable Recon goggle set, batteries, USB charger, USB cables, additional propellers, a low powered 5.8Ghz video transmitter and a 600 line CMOS camera and Fat Shark even includes 2 lightweight racing gates which can be popped open in a flash and hanged on anywhere to start racing.

Sharky QuadThe surprising fact is that this time we really got a flying shark. The “Sharky” quad is supplied with 4 x 8520 brushed motors with 9000KV, assuring to provide enough power for even 3D stunts if one desires it. The “Sharky’s” all in one vertical controller is a patented design, based on an F3 flight controller, configurable through Betaflight Configurator. The fins of the shark contain the antennas, the top fin provides the antenna for the 5.8Ghz video transmitter (FCC certified) and the back tail has the antenna integrated on for the FlySky compatible onboard receiver.

The 600 line CMOS camera provides a crisp and clear image, and if the firmware was not modified from the original factory one, it will turn into black and white image when the battery is low, so the customer knows that it is time to land.

Fat Shark Recon Goggles

With the release of the Fat Shark 101, Fat Shark introduces their newly developed single panel goggles the Recon. The recon will not be the choice of the high caliber racers, but for the cost of it you get a goggles which feel very natural and fall very nicely on your face. I had several people try on these goggles at our shop and the response was surprising. People who otherwise cannot wear normal goggles because of their prescription lenses replied with a “Wow” – all of a sudden they found a goggle which works for their eyes without the need of additional lenses. I personally felt the image a bit too close to my eyes at first, but after a few moments of use, it felt really natural and comfortable to use. The Recon goggles feature a frequency scanner (just a short press on the 4 way joystick) – that way it will scan for the highest RSSI signal on the selected band. Change the channels with short presses on the up/down button, if you press and hold the up/down buttons then you can change the band. Pressing and holding the 4 way joystick button will enter the OSD menu on the goggles. Here you can change some OSD setting – like how long will the OSD display show up on your image – or you can turn it off completely if you wish. The System menu will display the system information like FW version, sound on/off and a restore to factory default.

Fat Shark Recon Goggle Back

The faceplate of the goggles is covered with a very comfortable vinyl foam, which locks the external light out, but on the side of the goggles there are enough openings to allow airflow to avoid the goggles to fog up. The power to the goggles is provided by a single cell 18650 battery which will run your goggles for a good 2-3 hours or more depending on your 18650 mAh size. The USB port on the side of the goggles is used to charge the battery from a USB phone charger, for better performance we recommend a 2A power supply for this. The charging rate is about 500mAh per hour, so depending on how big your 18650 is it can take 4-6 hours to fully charge the battery

The goggles are supplied with a rubber-ducky 2db 5.8Ghz antenna to match the linear polarization of the antenna in the Sharky quad. There is a built in no signal warning, if you forgot your goggles on and there is no incoming video, your goggles will discretely stat beeping about one every 5 seconds. There is also a low battery alarm – a different beeping signal when your battery is getting low – up to the point when it gets too low and there will be an OSD warning on your display that it is now really time to turn it off and start recharging the battery.

Fat Shark RemoteFat Shark provides a 6 channel custom designed remote control with their 101 drone training system. As you can see on the image above, there are no extras, controls right to the subject. One switch for flight mode, another for arming, the gimbals have a really nice feel. Overall the remote fits very nicely in your hand, and it does not feel cheap at all as the remote from most of the Chinese kits. Size of the remote is small enough that a 6-9 years old kid can use it comfortably. Binding is easy as a breeze, you can use this remote with any other quad you own, just install a FlySky receiver in them and bind it to it.

Fatshark Kit OverheadFatshark even includes 2 spare motors with their kit. The Sharky quad has propeller guards providing protection again hitting the wall, as well as against unwanted fingers inside the spinning propeller area. Even with that we recommend keeping it away from small children and pets, because the high spinning propellers (around 19000kv) still could cause small cuts and bruises if not handled properly.

With the two gates included this kit is to provide hours of fun during the winter, I am sure lots of people will wonder and fly to every possible – inaccessible spaces in their living rooms. Fat Shark promised that they will sell gates separately as well, so one can set up a real racing course in the living room, to attract the love of their spouses.

Canadian customer can pre-order these kits from New Generation Hobbies clicking on the following link or the image below: www.nghobbies.com/cart/index.php?main_page=product_info&cPath=_207_234_229&products_id=2142

Fat Shark Quad

After you purchased your 101 Drone Training System, you will be able to register your product and with that get with free access to the Drone Racing League simulator (a $20 value) and three months of Academy of Model Aeronautics (AMA) membership and insurance (if you are residing in the USA, unfortunately Canadian customers do not get a 3 month free MAAC membership). In addition, online training videos and a detailed guide are included to help train new pilots. The Fat Shark 101 system promises a lot of extras as we go along, this is not a one time buy drone, but if you get this, and as you evolve in your piloting skills, Fat Shark will reveal in the future additional benefits which users of this system will benefit of.
