DJI S1000 Owners Thread - Mini Build Log

[blade strike]

​

I just received my DJI S1000 Premium. I thought I would share some photos of the build process. As you would expect and you should, the build quality is second to none. This is a complete new octo from the ground up. The S1000 V type design provides large amounts of thrust while improving power efficiency. I'm really excited to see the use of cf arms versus the plastic arms of the past. The most exciting part of this frame in my opinion is the folding capabilities. It makes transportation and storage a breeze for such a large frame. The locking system only takes a few seconds to fold or unfold, such a outstanding design. The S1000 comes about 80% complete, so the build process is very straight forward and FAST.

Once I opened the box I was shocked at the quality of the S1000, Top and bottom frame plates, arms and retractable landing gear are all made from carbon fiber.

Once I took the main frame out and removed the top shipping carton, I was amazed by 8 beautiful CF arms and motors. The motors are already attached and mounted with folding blades and blade holders. The blades fold just like a single rotor helicopters would, the blade holder is identical as well. The motors are installed above the 40a ESC's and all wiring is completed, the arms are truly PnP.

The manual starts off with you installing the arms first. My building area is rather small so I decided to install the electronics first and then install the arms last. I chose to remove the top CF plate, this allows for an easier install of the A2. Once the top plate is removed you will have full access to the power distribution board. You have the 8 motor power connections, 8 esc connections and 2 XT60 connections on top. One of the XT60 connection will be used to power the A2 PMU and the other one is free to power another device. On the bottom of the main frame you will notice the 24 pin ESC header, main power wires / connectors and 1 more XT60. The XT60 will supply power to the retractable landing gear and another device like the ZEN. The main power connector setup is very different from what I have seen but it makes perfect sense. The positive side utilizes a AS150 and the negative side is a XT150. This makes it impossible to reverse polarity.

Time to install the A2 IMU. Please notice the direction of the arrow on the frame and on the IMU, make sure these match and point forward.

Next I installed the main controller and PMU. I found that installing the PMU in the above area works best, you might find a better location. I then stacked the IMU CAN BUS on top of the PMU. Now you want to connect the main controller to the 24 pin ESC header. Make sure you connect the yellow wired connector to M1-M4 and the brown connector to M5-M8. Now connect the retractable landing gear controller to the main controller via the supplied servo jumper wire. F1 Output (A2) IN (Retract Controller).

All wiring is completed and ready to install the top cf plate. As you can see there are many option for a clean install.

Main frame all back together. As you can see we have plenty of room for extra gear. You also will have a free power plug to power items like a data radio for example.

The retractable landing gear is very robust and really thought out, and even has it' own integrated controller. The system has a solid lock in both directions and is pre-tuned from the factory.

The landing gear assembly is really simple. Just make sure you get the keyed end of each landing strut inserted correctly. Once you attach the spring from the strut to the retract system, make sure the spring is approximately 70mm when extended. The landing gear travel has already been preset at the factory, so no need to touch the travel adjustments.

As you can see from the pictures above, the quality does not stop at the frame. The motor system is another example of some incredible engineering. The aluminum motor mount houses the ESC and acts like one big heat sink. The motor is attached to a damping system that should help eliminate any vibrations coming from motors and or blades.

Installing the arms is incredibly easy. You first use the M4x35 screw to attach each arm. Wrap the power cable around the aluminum standoff and then connect it to the power distribution hub. Now connect the esc servo connector into the main board.

To lock the arms, Just bring them up and slide the lock until you hear a load click. This creates a solid lock with zero play. Once all arms are mounted you want to go through the A2 setup and complete the FC configuration. Please make sure you test all function including motor direction before your first flight.

My first impression after getting the s1000 dialed in was how smooth the craft is. Even with a steady 15mph wind she was rock solid. The A2's GPS hold was simply amazing. Even descending at a high rate was supper stable. Fast forward flight showed no strange behavior as well. The GPS lock is spot on and has a very surprisingly fast lock. This was my first flight with an A2 as well, this is all new to me

I currently have the A2 in intelligent landing gear mode. Still testing this mode out completely but liked it's features so thought I would enable it. I ran a few test on the landing gear and each time they preformed perfectly with no signs of binding or locking in either direction.

I flew the s1000 for 15mins and used just under 67% of my pack. It can fly forever w/o a payload. I have made over 12 test flights on this frame while I was waiting for my z15. This allowed me to build up trust in the A2 and other electronic components on the airframe. Everything has performed as expected. For a naked frame I found 170 Basic and 120 for ATTI felt really nice. These will defiantly change as I start to add some weight.

I'm currently in the process of installing the z15 and other components. I will be posting some in flight video and my final gain settings once I get some air time in with everything installed. I will keep the thread posted on any updates, GOOD or BAD as well. If anyone has questions or wants some pictures of something that is not posted, I will do my best to provide it.

It looks amazing...complete and utter jealousy right now! Congrats!

great thread and informative setup posts, I'm brand new to the world of UAV's but will follow this thread all the way...

Good build review with good, in-focus detail photos. Maybe you should head over to Bart's new Product Review Thread!

Perhaps DJI have finally come of age with this airframe. I do like the increased access to the important bits whilst still maintaining their reasonably tidy installation ethos. Interesting that they do not consider tilting the motors for increased yaw efficiency important with this frame.

It will be interesting to see how robust the boom locking hinge and clip are in the long run.

I am happy for you that your A2 has not done anything destructive - yet. The jury is still out on the reliability of that Flight Control.

Nice looking heli (is it Ken?)

why does DJI position the IMU near the edge of the frame when the A2 manual says to locate it as close to the CG/center as possible?

thanks,
bart

hey blade what size packs were you running, looks like a nice design that fixed some of the issues on the s800's. Do the arms have any flex?

... why does DJI position the IMU near the edge of the frame when the A2 manual says to locate it as close to the CG/center as possible?..

The IMU has always been slightly off-centre with the S800's, and even further away from the CoG if the damping tray is used. However, there is a facility in the setup software where precise distances of IMU and GPS sensor from CoG are entered to accommodate this offset. Their recommendation is only to do with vibration levels, which they state are minimum at the centre of the frame.
