Completely New to this! Please Help me out!
« 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)
http://diyrc.co.uk/mavic-build-diaries/mavic-clone-and-so-it-begun-(by-foldingllama)/60/

Here is my current parts list-

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you are close to have everything (you miss the ESC for motors), but some of your materiel is outdated;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Same GPS is outdated, go with a BN220 or BN880 or a M8N, as they give you faster GPS lock and more GPS and galileo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
