Hi everyone, sorry for the wait and for my late reply, I modified my build a bit, I am attaching you the complete file including all the components in .STEP format. Like that you can modify as you wish.

Here is the download link!
3d Printed Mavic Clone / Re: Roll Wobble

Thank you very much for the tips on the gains, itís made a massive difference. It flys perfect now with standard props, it isnít as stable with the low noise ones but very acceptable.

so made some improvements

1) colored it gray
2) routed the antennas inside the arms

waiting for camera now

the thing that worked for me is make a 4 in one out of 4 saprate escs , just arrange them 2 sideways and wrap electriccal tape and then same stack of 2 over it

there might be serval reasons
first check your gains i already posted suitable for og mavic motors

second thing is the low rpm power limit someting in blheli firmware that can cause those vibrations so turn that off (also mentioned in that post )
3d Printed Mavic Clone / Roll Wobble
« Last post by dickiebird1974 on April 04, 2021, 07:35:55 PM »
So I fired the Mavic clone up yesterday with the Naza v2 and some 20A blheli esc's with original Mavic motors. Everything fires up but I get massive roll osillations / wobbles.

Anyone else had this?
Not sure if you have figured it out yet but its terribly difficult. I ended up buying some super small 20A esc's and modifying the 3D files to mount in the arms but the strength of the arms takes a hit so its not great. Another option is the 4 in 1 esc which should solve space issues.

I have beefed up the front arms a bit to take the esc's without breaking, I can share them with you if you are still having issues.
Mavic Build Diaries / Re: Mavic 115% Build STL files

Did these STL files ever get published here, I've printed the one of the arms on the 134% and it seems over the top
for what I want.

Les Smith
I started this project 2 years back , and now finally its looking like something .... ;D

Build :

1) mavic pro naza 4.1 design
2) dji naza m lite upgraded to V2
3) original mavic pro motors
4) mavic pro low noise props
5) Favourite littlebee spring 30a ( blheli s)
6) flysky fsi6
7) HBP power 2200 mah 3s lipo

Flight time:

on 2200 mah lipo first level protection activated after 8 mins (11 volt load 11.5 no load )
10 mins of total flight time till second level protection activates and lands the drone (10 volt load and 10.5 noload )

issues I faced :

1) motor mounts - dji uses its own 3 screw mount for which the arms need to be modified , i posted those modified arms in this forum -  - use 9 mm m2.5 screws if you got longer ones either use spacer or cut screws

2) naza gps size issue -  i am using original naza gps which have round pcb for that you need to use modified round nose -

3) fsi6a rx pin header problem - using servo pins in this build is terribly hard task so just soldered to the back of the signal pins

4) naza led module not available or too big for your taste - i got my naza m lite used so it came with naza v1 power and led module (combined ) which you have already guessed is terrible to see from outside so i just installed a 5050 pcb which is very slim in profile , (purchase the version without resisters )  connections- open nazza v1 led module you need to solder 3 wires from it to (1) to gnd (2) to red (3) to green of 5050 led pcb

5) where to put esc - this wont be a huge issue if you get 4 in 1 in first place but if you got escs like me what you can do is arrange the escs like a 4 in one with layers of insulation tape of course its not so much heat efficient but can save some space and place it in backside of naza

6) usb interface for naza v1 pmu - naza v1 have usb port on pmu which gets very hard too reach sometimes so my solution was to find slimmest micro usb cable with smallest head and cut maybe 5 cm from it and solder male headers to it making my own usb extension and soldered female headers to remaining cable

7) programing esc - due to some power limitation in blheli escs your quad can shake a lot so took a advise from youtuber to turn it off  ( low rpm power protect ) -
&pbjreload=101 refer first comment

8) naza programing
- by default naza assist uses f450 gains to all the configs when you choose quad x in naza setup but due to fact that rear arms are lower then front arms it causes issues particularly speaking pitching very fast forward without even touching any sticks

found the working gains in this same forum ( cant thank him enough )'s-sort-of/msg6541/?topicseen#new 

use 108 99 100 100 config

9) more space - using optimized upper parts can certainly make your life easy -

some of my mods :

1 ) risers for arms and belly ( clip on pressure fit no need to glue or screw ) -

2) modified legs for mavic pro motors -

note : - coloring is still left and drone was going crezy at the beginning so don't judge me on those dirt marks  ;D

i have come way back from future just to say tank you , i was really started to get annoyed over my quad drifting and wasn't that much of a expert so couldn't set gains myself , your gains made my quad rock stable ... lot of thanks
