Mavic build by a drone and RC illiterate
« on: June 29, 2018, 04:45:20 PM »
Hello everyone, this will be my build log. As the title mentions I'm completely new to everything drone/RC so any help/advice/criticism is much appreciated! I have a Prusa MK3 and was looking for interesting 3D printing projects and stumbled upon this. I'm mostly done with the 3D printing (PLA so far but might upgrade to something else) so now I enter the realm of RC drones.


Here is my progress on the 3D printing so far.


I have used bondo, wet sanding and primer to try and get a very good surface finish. Only done on the top parts so far. After I'm satisfied with the surface texture I will add a new primer layer and then paint.

Picking and buying electronics has been way harder than I expected. Both to find the parts that I want (I live in Sweden so I have to source most parts for other China and so on) but mostly to understand what is compatible with what. If I have done any obvious mistakes please let me know.

This is what I have ordered so far:

FrSky Taranis Q X7 Transmitter (said to be D series compatible so I hope it is OK)
FrSky D4R-II
4 x Racerstar RS20A 2-4S ESC
4 x Racerstar racing edition 2212 980KV (saw someone else buy these and it was hard finding other with the lower KV)
SP Racing F3 flight controller deluxe (seems to be very good and popular)
DJI Mavic 8331 low noise propellers
MULTISTAR LIHV HIGH CAPACITY 3000MAH 3S 10C MULTI-ROTOR LIPO PACK
NZ mini GPS for NAZE32 (does this work with my F3 flight controller?)
HC-SR04 ultrasonic module
Matek mini power hub
Some LEDs
Some bluetooth module

Still looking to get the ball plungers, but don't know which to buy yet.

So I proably missed something major, but this will be a learning process and hopefully I can get some help from everyone here :)

Thanks for reading!

Small update:

I have received most of my parts now. However, the F3 flight controller I bought from China was specified to be the Deluxe edition but I received the Acro version. After several days of arguing with their support I got my money back. Have now ordered a new one from Hobbyking instead and I'm hoping they will send me the Deluxe version. I'm not really sure if it is important to have the deluxe version but I have seen many other on here use it so I figured I had a higher chance of success if I use it too.

Also noticed that my props cant easily be attached to my motor shafts. My motors have a M6 threaded shaft and the Mavric props have a 3 mm hole. Not sure how to fix this so anyone that have run into similar problems please let me know if you found a solution.

Also started to re-print the arms in PETG since I'm fitting the ESC in them and they might be hotter than the PLA can handle. Big thanks to Mkc2 for sending me the remade arms that can fit my ESC!! :)

My mavic is all PLA and my esc never got even warm so happy about that.
One of the guys on this forum just printed an adaptor and pressed the pins out and fitted the blades on or you could just design your own.

Good to hear that PLA works as well. As I'm reprinting with your files so I might as well do the in PETG for the higher impact toughness even if the temperature resistance is a non-issue.

Making an adapter is a very good idea! Do you remember who/what build diary this was made in?

Thanks!
