Please Note FW V1.4 does not contain the controller update you need to use V1.320 to update the controller to the latest build.
There is a LOT of confusion around controller in this update, please see below to see what you need to do regarding the update
There are 2 versions of the P3 controller, Model GL300A and GL300B, the Model is written on the rear of the controller next to the DJI logo.
GL300A : Up to FW 1.3.20 it could be updated via the USB port, Once you installed V1.320 future updates will be via the DJI Go App.
GL300B, Can only be updated via the DJI Go App, Anything before 1.3.20 is not relevant as there was no update other than via the App.
If you have the GL300B update is via the App only, No further action is required.
If you are currently on 1.3.20 then no update is required on the controller for V1.4.
If you are on V1.1.9, V.1.2.6, 1.2.8 you need to update the controller to v.1.3.20 before it can be updated via the DJI Go App.
If your on V1.1.8 or V1.1.9 you may need to update to V1.2.6/8 before you can update to V1.3.20
1: Install the New DJI Go App and see it it prompts you to update the controller, if it completes then your done.
2: If it says "RC requires upgrade" you need to upgrade the controller to V1.3.20 as per DJI update instructions listed below.
To update it you need firmware V1.3.20 file from DJI downloads page for your P3 model.
Note : V.1.4 does not include the controller update in the package you...Continue Reading

First thing make sure you remove the gimbal lock.
You need to get the P3 as cold as possible, ideally either place it on the patio at night for 20m or in front of some AC for 10m with the battery out.
The important part is not to turn on the P3 until you are ready with the app as the IMU is heated and the temperature start to rise as soon as you turn the P3 on, for a good calibration the process need to see the widest temperature range it can.
First put the flight mode switch in the middle position P-ATTI mode as this stops the popup menu coming up when you turn the P3 on.
Next open the DJI Go App and turn on the controller, navigate to MC Settings, Sensors and scroll to the bottom and you will see the IMU Calibration button. (P3 still off cooling at this stage) , you will see the IMU calibration button is greyed out,this won't come active until the P3 connects.
Place the P3 on a perfectly level surface and put the battery in and turn on, within a second of the craft connecting to the app the IMU calibration button will be available, press it as soon as you can and allow the calibration to complete, it takes around 10m.
Whilst in progress do not touch the P3 it needs to be completely still no movement or vibrations.
Once complete then perform a Gimbal calibration from the gimbal menu on the same flat surface.
Make sure you perform a Compass Calibration before you fly at the flight location.
My delivery arrived this week from DJI and i had ordered some of the new Carbon Fiber Reinforced Props.
After opening them up the first thing you notice is the finish, its outstanding, just as good if not better than the stock plastic, they also have a nice matte finish. Weight is identical to the plastic props @ 7g each.
After having a good look over them i noticed that they are really stiff compared to the stock plastic prop, whereas the plastic will bend from the tip these are rigid, when you apply enough pressure they will start to deflect but more in the middle of the blade.
Next i checked them on my DUBRO Balancer, they were all very well balanced, no action required.
First these make me really wish DJI would make the P3 in this matte black i think it would look fantastic.
After take off i noticed it sounded different, just a slight change in tone, no louder or quieter in my opinion just different, after some flight time i can say the props make the Phantom 3 slightly sharper, everything is a little more reactive to stick input, it also seems a little quicker reacting to big stick movements as well, after flying a full 2 packs i cant say i saw any change in flight time but i am at sea level so have plenty of air to play with.
I really like them, i do think if your flying at altitude they will help give you a bit more time, they are a quality prop and i will be using them as my main prop from now on.

I have been looking for a bench PSU for my chargers for a while and my modified 300W PSU with a lightbulb on the 5v rail to keep the 12v side in check has really been playing up so Last week i purchased the HobbyKing 540W 30A PSU
Spec is 13.8 to 18V at 30A so its pretty beefy and should give me enough power to charge everything iv got, it has duel post outputs and an pot on one side to just voltage.
At the time there was a lot of discussions over what to use to power it and can you use DJI's charger.
After i received mine i have been doing some tests,
first thing first the board its self allows you to connect 3 packs, each pack has a 0.22ohm 10W resistor in series with negative to give some overcorrect protection for the packs, the switch they state is to be used when using the original DJI charger, all it does is bypass the resistors and give straight negative to the packs.
the board also has voltage reading and elegant time remaining on charge, iv not looked into these TBH, the voltage reading seems accurate.
As for powering it, DJI Pro adapter is rated at 100w at 17.5v, after investigation and testing it the adapter is current limited to output a maximin of 6A, no matter if you connect 1 or 3 packs the adapter will only provide 6A, whilst charging a single pack up to 50% capacity the battery is taking the full 6A from the adapter, after 50% the current begins to taper off as the charger level increases, this means when charge a pack the adapter is only providing full output for around 50% of the charge time, the rest of the time its less tapering off as the pack get up to full.

Hi Folks, a big one this, iv been looking specifically into Apples devices supported by the Pilot app and thermal throttling and shutdown, i wanted to look into some of the possible reasons and ways around it, looking into it i have found a few conclusions,
First of all looking at Apple A7 devices, the Mini 2/3 iPhone 5S and the Air 1st gen.
Looking at the design both are similar with the batteries located next to the logic board, The SOC on both is located under a metal EMF shielding, this does not seem to offer any substantial heat dissipation, no thermal compound is used and it does not make contact with the SOC directly.
The interesting thing is all of the packages on the logic board are located facing up towards the screen, This means Apple are not making use of the Aluminium shell as part of a heat sink, the second thing with this is heat from the display is also reflected back towards the processors as well.
The A7 SOC , there are 2 versions of this SOC, a different chip in the Air than in the Mini 2/3 iPhone 5S. Its a Duel Core clocked at 1.3ghz in the Mini2/3/5S and 1.4Ghz in the Air.
The A7 in the Mini is a POP setup with the 1GB of ram stacked on top of the core as part of the chip, this is one unit with no metal heat spreader on top.

After purchasing my Phantom 3 Pro i needed something to carry it around in, this is my first Phantom so i had nothing to base any opinions on, one of my big gripes with my F450 was how to carry it, at times id resorted to a cardboard box, for my expensive new toy a box was out the question.
so looking around the internet id come across the FEARLESS ENGAGE Backpack , it looked exsacly what i needed but was struggling to get one in the UK, also the fact this thing had been bleeding my dry for the past week i needed to look at cheaper options. After some looking around i found the MultiStar Deluxe Multirotor Travel Backpack on hobby king, whilst on the HK page looking at it i had a box pop up and offer me £3 discount on it so i though hay why not give it a shot, i just need something to carry it in for the moment, as usual with HK it was on next day so it just arrived.
Upon opening the box i was pleasantly surprised, its large and plenty of room ,Overall i was reasonably happy with it, i had modified it to allow the handset with tablet holder to fit, just 2 minutes with a knife and i was done, these are several placed you can remove foam to do this and i decided on towards the bottom, the RC find is perfect once this is done and leaves plenty of padding all around, the Phantom 3 in really nicely, it sits almost flush allthough the motor threads do stick up slightly but there is plenty of padding in the top so its nothing to worry about,
