New build by a newbie.
« on: July 14, 2019, 10:50:37 PM »
Hello all.
A friend let me fly his Mavic a couple of months ago and I've been wanting to build one ever since.
I know very little about drones although experienced in electronics and 3D printing and I'm not sure which to build though: the MAVIC F3 v4.1 or the NAZA v4.1.
Can anyone suggest why one might be better than another?

Any suggestions/feedback appreciated.

Just printing the NAZA to see how it goes, and so far the parts fit together beautifully (will be donating via paypal).


cheers

Printing is going well.
I managed to score 4 rolls of yellow PLA cheap, so I'm using that for the first printing attempts, though I'm not expecting the first prints to be anything more than practice & learning.
I have some PETG. Though I've never used it before, I thought that would be better for the flying version.

I'm impressed with the designs.
Printing all of the 4 legs at once was maybe a mistake.. Cura estimated just under 10 hours.
So far it's been six and a half.  :o

Donation made to CdRsKuLL in thanks for these designs and info.
Much appreciated.

Making progress. Printing is proceeding and most of the parts are done. I just need to get some nice nuts and bolts.
Ordered 4 motors: Black Widow 2204 2100KV.. 2x CW and 2x CCW.... Hopefully that's right.
Also ordered the DJI Naza V2 flight controller with GPS
I'll be watching that letterbox!

I'd appreciate any suggestions for a suitable transmitter/receiver since I have no idea about these things yet.
I'm wondering if the FlySky FS-i6 would be OK?

Hi,

the transmitter should be OK. I made the F3 version, but I see you go for the Naza version. Quite curious about your build.

I got  this version of the transmitter: https://www.banggood.com/Flysky-FS-i6S-2_4G-10CH-AFHDS-2A-Transmitter-With-FS-iA10B-Receiver-p-1061496.html?rmmds=search&ID=23342482&cur_warehouse=CN

The 10-channel is nice for programming, but it is very large for the mavic. I had to dismantle the plastic cover to make it fit. In your proposition there is a 6-channel receiver, which is much smaller and therefore fits better.

Good luck! Just flew mine again twice today!! Really enjoying it to practice flying!

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!

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.

cheers,

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 :)
https://www.thingiverse.com/thing:3207521
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:  https://www.thingiverse.com/thing:3803370/files

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.

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.
