Hinkenborp's Mavic Clone Build Diary - 07/2020 onward
« on: July 31, 2020, 05:55:55 PM »
Hey there, I stumbled upon this forum a couple months back and had spent a while pondering whether I wanted to invest some money into creating my own Mavic clone. I'm quite experienced in 3D printing and wanted to find a fun project to work on, and I think this will be a good one considering my past interest in drones and my current interest in 3d printing.

I have tried to put together the best possible parts list for my own build of the Mavic clone, but I wanted to see if anyone can doublecheck my list and put me in my place if I'm way off on what I need to get this thing up and running.

I would really appreciate any help y'all can provide, so I can get going on this project!

Here's the pages I am referencing for my build-
Original STL files & Build-
http://diyrc.co.uk/3d-printed-mavic-clone/mavic-clone-stl-files-version-3-0-f3/
Other users' more recent builds (some parts from the original build are no longer available online from what I can tell)

Can anyone tell me if I have everything I will need? Is there anything on my list I won't need, or won't be compatible with the other parts?
I have a 3D printer, soldering iron, heatshrink and screws already, so I didn't think I'd need to rebuy those.

Honestly I'm very new to the custom electronics & DIY RC community, so I've tried my best to put together a comprehensive list that covers all my bases on this project, but I figured I'd put it out there and see if anyone can help me out.

Again, I'd really appreciate any help/advice you can provide, and any resources that I could find useful would be greatly appreciated.

Thanks so much!

Hi

you are close to have everything (you miss the ESC for motors), but some of your materiel is outdated;

i would recommand going with a F4 or F7 flight controller, cause F3 are less and less supported by Betaflight, Inav or Ardupilot

Also, i would consider going with a Flight controller that include PDB (power distribution board); a lot of F4 or F7 does that
(you will need some space in this quadcopter, so the less materiel you have the more space for battery)
Same GPS is outdated, go with a BN220 or BN880 or a M8N, as they give you faster GPS lock and more GPS and galileo

The sonar, you can go with it, but not very precise;

You need ESC for motors, the best would be at least 20A; depending of how you print, you can go with 4 in 1 ESC or 1 by 1 (and put in arms, if you get the stl on this forum)

No need for stepdown converter, a good PDB or FC+PDB is enough
(PS: if you go for a PDB 'solo', goes with one with 5V and 12v bec)

For the lipo, don't know if this one is not too big for the drone; my max was a 3S at 1500mAh

hi
nice printing and painting :)

concerning your list, it should be OK
Just one think, the sonar type HC-sr04 are compatible with this 3d print, but not the TFMini, as you will have to modify design to be able to put it downard
Personally i used a GY-US42, because also compatible with my firmware (ardupilot), but its not compatible with inav

@Hinkenborp, how's the build going?  I've never even flown a drone but this looks like a fun project and it's in my wheelhouse.  I'd love to give it a shot, but I'd really like to see a BoM and build experience of a newb like me that's more recent that the 2017 era postings on here.

@jchilders_99

Going very well (so far). Unfortunately I haven't been able to install very many components yet as I have been in the midst of moving homes! Waiting for me at my families' home is every remaining component I need to install excluding my XT-60 connectors, LiHV batteries and charger. I printed my pieces in Overture PETG, which I highly recommend (it prints extremely well, and is non-toxic & much stronger than PLA). Should be setting up the majority of the project in the next two weeks or so. I intend to visit my local hobby shop to pick up the LiHV batteries and charger, after having done some research online I determined I am not necessarily qualified to make a well educated purchase on those (they can apparently be pretty unsafe, so I figured the guys who work there who have been flying RC planes & custom built RC vehicles for 25+ years probably know better than myself).

As for a bill of materials, I ended up purchasing everything off of my final list above from August 8th, excluding the LiHV batteries and charger. I can put together a detailed price list for shipping & general costs in the coming week if you'd like once I get settled into the new place.

EDIT: Also, just noticed that I'll need to put together a list of the various hardware I have picked up as well. I have a large box of metric machine screws of various sizes for my 3D printer, but most of what I needed for this project was missing as they needed to be much longer than the longest screws in my personal collection. Won't be an issue though, just going to add that to the checklist!

I did end up picking up a nicer soldering station than my original, for a bit higher cost since my old iron was rather beaten up and there seems to be quite a few small soldering contacts on the various boards.
This one here- https://www.amazon.com/gp/product/B01DGZFSNE/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

And got a bit of a better understanding of assembling the drone itself from a couple videos on youtube, namely these ones here-
Total basics of how the thing works:

More in depth guide on how to assemble and solder the specific components:
&t=1146s

Not 100% sure if these videos will apply to all of the components that I've purchased, but it's definitely helped me at least get an understanding for how the whole thing hooks together.

Hopefully this can help you out for now, and in the next week or two I will have a more in depth update of my personal build!

This was an excellent reference thanks! Now I have an idea of the concepts and can start doing some research.  Please keep us updated on the build!

I switched to Snolabs filament almost exclusively.  It's premium quality filament and the owner is awesome.  They have a PC+ that's as easy to print as PETG, with all the machining/strength properties of polycarbonate.  It's not cheap, but it's amazing stuff (I'd print everything in it if I could).  This project might give me an excuse to pick up the CF version :)

Thanks again for the info!

Heads up, those ESC's I picked up are much too large for this project. Working on finding a smaller set, but these ones won't fit w/ the default or the modified ESC holder arms. I had considered modifying the STL, but figured it's better to just find a new smaller set of ESC's to avoid adding more weight to the quadcopter.

On that note, the controller I picked up comes w/ a 10 channel receiver. Not necessary for the project, so I'll be replacing the receiver with a 4channel one from my local hobby store and/or Amazon if they don't have it there.
From what I can tell, only 4 channels for the ESC's to plug in, plus pairing are necessary, so 10 is pretty overkill for the base build. Maybe later on if I add a camera gimbal.

Thanks for the updates.  So I'm looking at an F7 and ESC stack.  It looks like it'll fit in the space as a package, but I might have to modify the the file a bit to mount it.

So the controller comes with a receiver?  That's why I couldn't find parts listings for receivers lol :)

Depends which controller you pick up. In my case, the FlySky FS-I6S controller came with a 10 channel receiver, but i did find this compatible 4 channel receiver on amazon-
https://www.amazon.com/GoGoRc-FS-iA4B-Receiver-Compatible-FS-IT4S/dp/B07ZMHGQLZ/ref=pd_sbs_21_6/133-8211563-7599826?_encoding=UTF8&pd_rd_i=B07ZMHGQLZ&pd_rd_r=8c64fa5b-8245-4846-84fe-d3440d026cee&pd_rd_w=MBzrp&pd_rd_wg=iCgHN&pf_rd_p=703f3758-d945-4136-8df6-a43d19d750d1&pf_rd_r=4YVWW9XA281XT6PVVX9H&psc=1&refRID=4YVWW9XA281XT6PVVX9H

Which I'll probably pick up if my local store doesn't have a receiver that is compatible w/ my controller.

I would make sure if you go w/ the F7 and ESC stack that it does not intrude on the vertical space above it too much as that is where you'll be housing the battery. I have seen a couple modified battery covers on the forum here though, which would provide you with more battery space. It's a pretty tight compartment to build in!

Alrighty, so I've settled on using the same 10ch receiver as before, it's already paired with my controller which should make things easier.

I picked out a new 4in1 esc to replace the set of 4 larger ones I had before, this way I don't have to reprint the arms and i'll just sell the old set that I decided not to use. This one here is what I've decided I like- https://www.amazon.com/dp/B079G5VN68/?coliid=I3KY5V1ROMIOHD&colid=L11C3G8PIIDN&psc=1&ref_=lv_ov_lig_dp_it

I used a pair of sidecutters to take off the original mounts in the front of the design to make room for my receiver as it's pretty large (also removed it from its original shell, as it just takes up unnecessary space), and i've found a nice guide for wiring my specific flight controller-
http://www.mateksys.com/?portfolio=f405-std#tab-id-3

Last but not least, I found a very useful resource here: https://dronenodes.com/how-to-build-a-drone/#tab-con-25
that pretty much breaks down every possible step of the process besides the 3D printing part, but being realistic, that's not been an issue for me, it's just been the electronics side of things.

I picked up a battery charger & battery from my local hobby store today as well. Lectron Pro ACDC-10A charger for $65, and a Lectron Pro 3S 11.1V 1800mah 50C LiPo for $35.99. The guys at the store suggested to store the batteries & charger in an old ammo box while charging to protect against fire, or in a cinderblock box on concrete (in a basement or garage) to prevent fire from spreading if anything did go south while charging.

Once I get the new ESC here, and wire everything up I'll be taking it out for the maiden voyage. Here's hoping that happens soon!
