DemonRC NOX5R XL - The Build made in EU
#1
Hi , 
Today I will introduce another superb build designed for racing, the low-riding or freestyle. 
His supreme specificity is that it is almost entirely European! 
Indeed, it's not just the carbon chassis is manufactured in Europe but also the flight controller and power distribution and regulation plate with integrated filters.

Make the "ola" in NOX5R XL produced by DEMONRC.

manufacturer specifications for this chassis
Carbon frame 215mm motor engine. 
80g weight 
carbon 3k Arm 4mm 
The rest of the frame is 1.5mm 3k carbon

Components List
For this build I used the following component list (click on the components to be linked with the buying site): Unboxing the chassis
The frame comes in a padded envelope that makes the taf! 
Do not fear the damage .. everything is packed as it should.

In the envelope, a printed box to the designer of the logo.
[Image: DEMONRC_NOX5R_XL_unboxing-11-1024x768.jpg]

The box is opened by unfolding ... 
A small black bag, tightly sealed and stickers. 
We love receiving the extras like stickers dedicated to our passion gear; personally I paste all over my box to lipos.

In the small black bag include our carbon parts perfectly machined and a small bag containing all necessary hardware.

Any set on balance this is what happens. 
The manufacturer information 80g, here it will count down the zip bag that packs fasteners and additional hardware that was added ... well almost there.

Owner of the Tour
I assemble everything and I present the beast ...
[Image: DEMONRC_NOX5R_XL_unboxing-13-1024x768.jpg]

Hours later, the birth of the beast. 
This was not without difficulty because I had to adjust a little, there a few aberrations in the design of the chassis .. hooo no worries this is corrected very easily! I would these corrections later ... 
But there's no denying she is as pretty as the official photo.

If you want the canopy version, know that the .stl the canopy is available for free download on the product page of the frame. It will do is print in 3D and go up.
[Image: DemonRC_Nox5XL_A-19-1024x772.jpg]

Front view, camera (here a runcam eagle) is held on both sides by a screw on each side. 
The camera abuts on the bottom plate of the chassis so it has some original angle ... it's not so bad because if the camera goes down with the vibrations, it never will point to the low. 
With the viewing angle offered by the eagle camera, no worries, even with a little tilt of origin is clearly seen on the horizon before us. 
The screws of both sides allow to give more angle to the camera and thus to point to the sky if you want to fly like a beast.
[Image: DemonRC_Nox5XL_A-11-1024x683.jpg]

A little sexy view taken plunged side: p 
The entire frame stands by nylon spacers and aluminum hardware. 
So far I have not broken but I feared that with a somewhat violent shock frame is dislocated. 
The day that happens, I will release aluminum spacers.
[Image: DemonRC_Nox5XL_A-13-1024x751.jpg]

Ass ass beast.

View of the end of the profile arm and engine brotherhobby 2205 2800kv ... it will scream severe 5S! 
The propeller mounted here is a dalprop 4 × 5045.

Electronic sandwich. 
Demon core underneath (PDB filtered with spouts) and demon soul F4 above. 
Below and above the demon soul F4, on the 4 fixing screws, I placed the small O-ring seals to filter vibrations.
[Image: DemonRC_Nox5XL_A-9-1024x683.jpg]

View from the other side of the PDB, from left to right I placed camera power supply (12V) video transmitter power supply (12V), a bridge between video in and video out because I have no OSD and power flight controller (5V)
[Image: DemonRC_Nox5XL_A-10-1024x683.jpg]

The arms were filled with carbon 4mm, there are 4mm. 
Carbon is good quality, well-milled.
[Image: NOX5R_XL_DEMONRC_REVIEW-2-1024x683.jpg]

The top plate is 1.5mm thick as informed.
[Image: NOX5R_XL_DEMONRC_REVIEW-3-1024x683.jpg]

Ditto for the bottom flat .. 
Congratulations respected manufacturer data![Image: 1f642.svg]
[Image: NOX5R_XL_DEMONRC_REVIEW-4-1024x683.jpg]

The frame is about 36mm high (of the screw head top plate to the bottom flat head screw).
[Image: NOX5R_XL_DEMONRC_REVIEW-5-1024x683.jpg]

My build weighs 337G LiPo out. 
It is in the average.
[Image: DemonRC_Nox5XL_A-1-1024x683.jpg]

Constraints and Changes
First constraint is the location of the battery if you want to place it under the frame to lower the center of gravity (on top no problems). 
Under the chassis we recover two passes for the battery strap, but the passage is blocked by the arm ... 
If we want to pass it a little higher, by the top of the sandwich bottom plate / arm / middle deck there was no machined openings. 
To secure the battery below, it will simply slip the strap battery as PDB (if any) or in the flight controller if it is only in the chassis.
[Image: 2017-03-19-14.39.05-1024x891.jpg] [Image: 2017-03-19-14.39.2-1024x806.jpg]

The blue aluminum screws may well be super light and beautiful effect, it is also very fragile. 
A key shot too and that is the insured breaks! In general, there is an additional screw in replacement in the bag so be soft on the clamping! 
Be careful to use the correct spanner as the center of the allen head (where you place the key) tends to round off very easily.
[Image: IMG_4335-1024x678.jpg]

At the center of the chassis, where the electronics are placed they also placed nylon spacers to solidify a little frame that holds with nylon spacers.
[Image: 2017-03-19-14.39.26-1024x806.jpg]

Only once it has installed its electronic spacers are too large and are dishing the top flat. 
You will need to gently cut the spacers to adjust the top flat flat. 
Another trick is to place the front and rear of the chassis 4 30mm aluminum spacers replacement of nylon spacers, just to be very solid, and remove the 4 central spacers.
[Image: 2017-03-19-14.38.1-1024x619.jpg]

Another disadvantage of both spacers and of such sandwiched flight controller is that the vibrations will be much more easily transmitted to the flight controller! 
So I mounted the flight controller on seals o-rings to reduce vibration.
[Image: 2017-03-19-14.38.3-1024x619.jpg]

You will notice also by analyzing the picture I placed an additional fpv filter on the power camera and video transmitter (the stuff packed in the blue sheath). 
In fact, although the PDB is already filtered, I have a ton of noise in the video stream as soon as I turn on the engines .. the video is unusable if I increase the gas. 
The placement of a filter in the supply line FPV removed parasites definitely!

About electronics
I have chosen for this build to test their F4 flight controller called DEMON SOUL F4. 
This is a flight controller for high performance ultra-fast calculations resulting in a stunning outfit in flight and very fast reactions to various stresses. 
Compatible raceflight betaflight and you'll be spoiled for choice for your tests. 
Me I adopted betaflight because I do not rediscovered myself with raceflight (some incompatibilities between the mistletoe available in chrome and the proposed firmware). 
FC format 36 x 36mm (30.5mm x 30.5mm for the mounting holes) for 2mm apaisseur, has a latest generation F4 processor clocked at 192MHz, a gyro MPU6000 SPI and all inputs / outputs required ( 3 UARTs, ppm / sbus, buzzer, vbat, etc ...)
[Image: Demon-Soul-F4-Flight-Controller-1024x768.jpg]

Here is the wiring diagram of the latter. 
This share screen printing side of the flight controller facilitates the implementation.
[Image: Demon-Soul-F4-Flight-Controller-Connection-Diagram.jpg]

Frankly, this is a flight controller that I recommend, I really appreciate his incredible flight performance and best of all it is cheaper than most high-end flight controllers. 
Do not rely on price, here it is in the very high end!

I took the opportunity to, at the same time test the demon Core v2.3. 
Upscale PDB (Power Distribution plate), this electronic control unit will facilitate wiring of the power supplies of the machine. 
The PDB also incorporates a 12V spout (600mA) available from a minimum use 4S, a 5v spout (400mA) available from 2S and filters on power. 
In addition it also allows easy connection of an OSD. 
It is protected against polarity reversal, supports 2S until 8S, is the standard dimensions 36 × 36 to 4.5 mm thick, weighs only 7g and supports 120A continuously (peak 180A).

The Demon Core v2.3 is presented in an antistatic bag zipper.
[Image: DEMONRC_DEMON_CORE_23-1-1024x683.jpg]
 [Image: DEMONRC_DEMON_CORE_23-2-1024x683.jpg]

Top view and components that compose it, it is noted solid capacitors for filtering the power supplies, two controllers for the 12V and 5V and an inductor.
[Image: DEMONRC_DEMON_CORE_23-3-1024x683.jpg]

Rear view. Screen printing is present on both sides, it is well thought out and super convenient!
[Image: DEMONRC_DEMON_CORE_23-4-1024x683.jpg]

A weight 8g.
[Image: DEMONRC_DEMON_CORE_23-5-1024x683.jpg]

Here are the actual measurements. 
The PDB is 36mm x 47mm, mounting holes are 30.5mm x 30.5mm. 
The total height of the PDB with component thicknesses range is 4.3mm, but the basic PCB only 1mm!

[Image: DEMONRC_DEMON_CORE_23-9-1024x683.jpg] [Image: DEMONRC_DEMON_CORE_23-6-1024x683.jpg]
Note that the output current available on the beaks decrease with increasing supply voltage, refer to the table in the manual to know the acceptable load your operating voltage. 
Do a quick calculation of your consumption and make sure it is accepted by the beaks!

The bps operation manual is here
My small contribution
As I wanted a runcam carrier to make a video on board, I quickly modeled a. 
At its simplest, best and 40 degrees of tilt!
[Image: NOX5R_XL_DEMONRC_REVIEW-6-1024x683.jpg]

The STL file of this support.
Flight Video
First test flight of NOX5R XL to see the behavior of this new flying machine ...

Conclusion
I was attracted by the design of the chassis, as its lightness and modularity. 
He suffers from some minor flaws like aluminum screws too fragile, nylon spacers need planing or lack of a battery strap, but these small flaws are quickly forgiven once the changes and chassis set flight . 
We appreciate the opportunity to download a canopy or camera media to .stl file and print it in 3D, but we do not regret having a canopy provided with the chassis base. 
Once airborne it was amazing! the paths are fluid and natural, the machine is hyper responsive to requests and I did not see any strange behavior on the tens of LiPo has already absorbed.

About electronics: 
You can buy the "DEMON SOUL F4" and "DEMON CORE PDB" eyes closed, you will love the performance of the flight controller and this card very high power distribution range!

BIG UP to DemonRC manager that is very responsive and attentive to their customers !!! 
My few requests sent through Facebook had response and solution found immediately (or at least very quickly because I sometimes sends out messages timeslot).

Nice review and a pretty looking quad.

I don't like the use of the flight controller as structure though. Firstly because of the vibration problems that you mention and also because circuit boards don't handle the shearing stress they are subjected to in crashes when they are used like this.

Great review. 

Just info from my side - the middle spacers are pushing the top plate because you have used vibration isolators. The gyro used on the Soul is not so sensitive to vibrations as the one used on Revolt for example, so it doesn't really need isolation (though I understand it always helps).
Find me on Youtube and Instagram. I currently fly: DRC Aura, NOX5R, Minimalist 112 and drive a scrap RC car
