Some great ideas and nice work.
I hope you will come back to it one day.

Sounds like an interesting project.
How is it progressing?
Any pics?

Hi Jarrod,

If you don't want to buy from China, you can get them from this UK manufacturer:

They have plastic and stainless ones.
I >>THINK<< this model (stainless) is the right size: Part# 838-203
The stainless ones aren't too pricey, but freight from UK to AUS was ridiculous...

Hi Stephan,

This forum has a lot of good info, and some knowledgeable people AND some great STL files for Mavics, but I get the feeling that there isn't a huge amount of interaction or activity.

How did you go with your choice of transmitter/receiver?
After a little research and some discussion with 'foldingllama' who is building a Mavic clone too, I've bought  the Flysky FS-I6s 10-channel transmitter plus the FS-IA6B 6-channel receiver. I haven't installed the receiver inside the Mavic body yet... it's quite large, so I'll have to modify the body somewhat.

BTW, if you haven't seen it yet, foldingllama's build diary has lots of useful info:

I've made a second version of the Mavic base that allows the NAZA V2 parts to fit better.
Slow process: the print took 14 hours, but came out fairly well, and now the Main Controller and the PMU fit snugly inside.

.. also found that the motor power wires had been damaged by a kind of "guillotine" action when the arms are rotated.

3d Printed Mavic Clone / DANGER... motor power wires
« on: September 08, 2019, 01:35:31 AM »
I'm building the MAVIC NAZA v4.1, and making lots of small mods to the body parts so the NAZA components will fit better (
However when I disassembled the arms on one of my prototypes this morning, I saw that the insulation on the power wires of the two arms had been cut and pulled apart.
This was after only a few "openings and closings" of the two arms I had assembled, so I wonder how things will go after a period of actual use?

The openings on the arms and on the body to allow the wires to pass through are quite small and also sharp-edged, and I think this is the main cause of the problem.
Also, the power wires on my Black Widow 2204 motors are quite thick.

Has anyone else seen this?
Any fixes or ideas to prevent?

Apart from the risk of fire, there's a likelihood that a short or even possibly the complete severing of a power (or perhaps a control) wire will cause a crash.

I've enlarged the holes in the body and also used a scalpel blade and a file to "bevel" the edges of the body and arms where the wires pass through, hoping that will be enough to reduce the problem.

That's strange. There was a nice diagram when I looked last week....
The link has been changed... I found the original link in my browser history:

Hooray!!  Naza V2 electronics have arrived and I'm in the midst of modifying the chassis a little so things fit better.

I couldn't get the PMU to fit nicely into the existing base, so I edited the STL to remove the two rectangular, wedge-shaped posts between the Flight Controller and the PMU and replaced it with a thin, flexible wall. 12 hours of printing later, much better, but I need to drop the PMU about 1mm lower... so another version will be needed.
Also raised the little post that supports the battery-bottom plate by a couple of mm so that the battery-bottom doesn't have to flex so much, but will still hold things down OK.
Another addition is a little translucent window in front of the LED. No big deal.. just something I wanted to add.
The new base is the grey one in the images below.

The next job will be to modify the case to allow the GPS and the FS-IA6B receiver to fit nicely.

Also wondering how best to mount the FS-IA6B antennas... any suggestions welcome..

Happy to make any of these STLs available if anyone is interested.

Waiting, waiting... waiting for my flight controller so I've been experimenting.
Because I'm not sure how all of the electronics and (recycled 18650) batteries will fit, I made a "hunchback" version of the Mavic.

Also modified a version of a little camera Gimbal that was originally posted by @lancerevo4
i have made a gimbal vor this :)
I couldn't get the gimbal motors in his design, so I bought some hollow-shaft 2204 motors.
Unfortunately, these are much bigger than the ones in the original design, so I redesigned the gimbal parts from scratch.

In case anyone is interested:

No idea if this will work on my clone.. even without the camera, it seems pretty heavy, and mounted all the way up on the nose, I wonder about C of G.

Nice diagram and great that you are sharing it, @anonflem
I'm building the 4.1 Naza so not directly useful to me :-( however you've inspired me try to do something similar once I get mine wired (which will be some time since I'm still waiting for the flight controller to arrive).

Something arrived in the mail...  ;D

HA! Yellow.. yes. I found 4 rolls of yellow PLA for a good price, so I'm making lots of yellow things lately.
I'm not sure what the final product will look like colour-wise but I'm thinking of using PETG.
My printer is an Australian made Wombot Exilis printer. A few years old now but we're used to each other.

I see you have folding props. Can you tell me where you got them?

By the way, after your comments on transmitter I did a bit of research and have ordered the Flysky FS-I6s 10-channel transmitter plus the FS-IA6B 6-channel receiver, so I'm hoping I can fit it into my Mavic clone.

Thanks Foldingllama.
I think I need to read-up a whole lot more about transmitters and receivers since (apart from a couple of minutes with my friend's Mavic) I've never used RC and know nothing about it.

I think I've chosen well with the Naza V2 more through luck than brains.
Just have to wait... wait... for that and the motors to arrive.

And the props.. and the ball plungers...

I'm off to buy a whole bunch of M3 nuts, washers and bolts today so I can assemble my 3D-printed parts.
At least I can buy those locally!

Looks like it flies beautifully!
A long time since you posted though... Still flying now?

That's brilliant.
Impressively stable and flies beautifully.
I hope mine works as well... just waiting for electronics and motors to arrive.

Those videos look suspiciously like they were filmed in Aus...?
