Title: Mavic clone... And so it begun... (by FoldingLlama)
Post by: foldingllama on December 21, 2018, 08:38:34 AM
Hi all!

Yesterday I finally decided to go for it and start y project on the Mavi Clone.

First of all: a BIG THANK YOU to CdRsKuLL for this site and the design (and off course to all you out there providing valuable information, tips and tricks)!

I will go for the Version 4.1 F3. I downloaded the STL-files and made my first prints (on an Alfawise U20), starting with the middle (although I'm not quite sure about the difference between the STL-files of "middle" and "base middle", but in one of the treads I read the files to print and there "middle" was used, so I went for that").The result seems to be good in my opinion. One of my nicest prints untill now (see the pictures).

I'm also compiling a document with all the parts I'll use. Once finished, I'll upload it. It is, off course, based on the things I read in the tread of CdRsKuLL and the responses you all gave on that.

I know it will be a trail and error (mainly the electronic parts), but that part of the fun  ;)

Thanks for providing me with some feedback and support whenever needed  ::)

Greetings and happy end of the year!

Hi foldingllama good luck  ;)

The printing continues. Just having questions on the sonar pieces:

In meanwhile I'm trying to find the right electronic components. I will post the list here once I compiled them, to get some feedback on them.

I read the different treads and I would like some feedback on the electronic parts I would buy. This is what I have in mind at the moment:

Is there anyone here that could tell me if these would work?
Am I missing some parts (besides a solder gun)?

Thanks!

Hohoho... Printing Rodolph (the red nose Mavic) is almost finished.

For the catch it is the one from the NAZA compilation you'll need, even when printing the F3-version. All other parts seem to fit fine. for the gimbal you'll need to cut a but off at the shortest parts of the gimbal to make it fit. Also at the rear foot, you'll need to scrape off a little bit to make it fit the holes of the base. But else, everything fits perfectly!

Next part: ordering the electronics  :-\. Luckily this is a hobby. Just hoping not needing to re-buy too many parts multiple times when failing...

You're welcome.

Thanks for that information you provided!!!!! seems to work as a charm!

Now waiting (first parts will arrive on the 3rd and 18th of January; the others will take longer) and printing the last parts...

M3 x 35 for connecting the body parts? Do you mean the long ones that hold the base to the middle frame?
As I say, measuring mine they look more like 60mm but we could be looking at different parts.

I notice you still haven't mentioned the ball plungers, you need 6 of them 6mm diameter 7mm long.

Kananga, indeed, still need to check that. The plungers are mentioned. Thanks for that!
Title: Re: Mavic clone... And so it begun... (by FoldingLlama)
Post by: foldingllama on December 29, 2018, 01:10:18 PM
Sorry, my bad I see them now.
Ive got mine laid out now, I'm going to be updating my thread soon. I'll be able to double check the lengths.
I need to draw and print some new bits for mine before I can assemble it.

Did you go for the runcam split in the end?
It has fpv built in so it's a good option.

Kananga, indeed 60 mm for body parts to assemble (base + middle). Just tried it. I also bought those. I'll adapt my list.
Title: Re: Mavic clone... And so it begun... (by FoldingLlama)
Post by: foldingllama on January 02, 2019, 11:36:47 AM
Finally decided on the webcam (after some good discussions with Kananga):

Besides this I also added a lipo bag (http://www.banggood.com/Explosion-Proof-Fire-Proof-Bag-For-Li-Po-Battery-NO_1-3-p-984705.html?rmmds=cart_middle_products) (--> seems perfect for the ordered batteries) and a second spare of prop releases (http://www.banggood.com/Quick-Release-Propeller-Blade-Base-Mount-with-Spring-Screw-for-DJI-MAVIC-PRO-p-1141705.html?rmmds=cart_middle_products)--> these don't work --> you'll need to print an adapter as Kananga made.

Now we need to wait... Fingers crossed  ;)
(Thanks Kananga for the advice)

I got the black recieiver for the phone, the white one seemed to only have one ariel. You choose at checkout.

I admit I haven't revisited gimbal controllers since I bought a set up for a much bigger project a while ago, as soon as I find the box with those bits in I can see where I'm at but I think it's the same controller I've got.

I'm nearly finished redrawing the base, it might even be more suitable for your build if your fc doesn't fit the original, I'll post up my results soon.

Your getting close to finishing it :)


Indeed, I also got the black one.

Finished...??  ??? Still need to start mounting and connecting everything...  ::) That worries me most ;)

Hi Antonello,

No, the rubber pads are to dampen the movements so the camera is not shaking. For the gimbal I'm looking if I can get one of these modified:

So, still some work to do, but I'll need to receive the ordered parts in order to create an adapted gimbal (except if Kanaga is finishing one ;) )

+ firefly mini : https://www.thingiverse.com/thing:3328503
following a rubber balls version to take out the vibrations.

Could work, but the legend 2 is a bit broader than the firefly. So the arm facing forward, needs to be a bit wider to the side to get the cam in the middle of the Mavic.

Designed this in what software? For which motors? Mine will have a diameter of 22 mm.

In order to get more clearance for the cam and the mavic in general, I'll print some leg extentions. The rear leg of this (https://www.thingiverse.com/thing:2028673) works perfectly, but the front feet are too wide. I'll try two things and provide you with the result:

I only noticed last night that the rear arms don't have holes for legs, I printed 4 legs out but cant attach the rears without adding holes.

the rear one goes in the holes ot the one foot at the back. not at the legs.
Title: Re: Mavic clone... And so it begun... (by FoldingLlama)
Post by: foldingllama on January 04, 2019, 08:54:40 PM
At the back you have only one foot (as you see here: https://www.amazon.com/Mavic-Remplacement-Landing-mavic-MOLDED/dp/B072K8WTSP). There you also see the wholes. The first site on thingiverse has 3legs included: two for the front and one for the back. the back foot extention works well. The front extentions are too wide.

I have no feet for the foldable rear legs.

Have your gimbal motors come? What they like? I'm thinking of getting the same ones.

Not yet. They are in the post office, but I need to pay an import fee and didn't get the notice I need yet.

First soldering is done and the voltages are perfect!
More to do over the next days / weeks (but still awaiting my gimbal motors and my transmitter/receiver)...
Title: Re: Mavic clone... And so it begun... (by FoldingLlama)
Post by: foldingllama on February 02, 2019, 08:55:07 PM
so, today I advanced quite a bit, with ups and downs...

The downs:

The UPS:

Next step will be to look at the sonar and connecting the motors to the ESC. as I can't put in a GPS, I'll mount the front legs and will be soldering the wires to the ESC.

Bummer on the GPS... Maybe I'll just try it without the GPS, Sonar and LED's...

Think I'm going to order from somewhere else in that case.

Just informed at the post office. Nobody knows where the package is. So the sender needs to ask for an inquiry at his shipping service... Curious what will come out of that. So I think I'll start off without the cam...

My bad, I'm repairing my printer today, I'll sort the adaptors for you.

No hurry Kananga! I'll start with the GPS and Sonar. Then I'll configure my LEDs. Printing won't be before the weekend.

OK, so GPS, sonar and LEDs working and configured! YES!


Next step was to check if I could connect the cam, but there I'm completely stuck...

The Foxeer Legend 2+ has 4 cables coming out (2 black, 1 yellow and 1 red) (https://www.banggood.com/Foxeer-Legend-2-F2_8-155-Degree-Wide-Angle-12MP-HD-WiFi-Camera-For-FPV-Racer-Drone-p-1053384.html?rmmds=myorder&ID=224&cur_warehouse=CN):

The FPV-transmitter (https://www.banggood.com/Eachine-VTX03-Super-Mini-5_8G-72CH-025mW50mw200mW-Switchable-FPV-Transmitter-p-1114206.html?rmmds=myorder&cur_warehouse=CN) has:


If I'm right I only need to connect those on the mavic and install the Go FPV-app of the FPV-receiver (https://www.banggood.com/Eachine-ROTG02-UVC-OTG-5_8G-150CH-Dual-Antenna-Audio-FPV-Receiver-for-Android-Tablet-Smartphone-p-1242422.html?rmmds=myorder&ID=224&cur_warehouse=CN). Is that right? But how do I connect the FPV-receiver to the FPV-transmitter? Only long pressing so it scans all frequencies?

No other connection to be made with the FC but the pos and neg of the FPV transmitter?

But I could also hook up via the foxeer-app directly and control the foxeer without all that if I'm not mistaken. That goes over Wifi. Just tried it, and it seems to work fine. Moreover, I can control when and where to take pictures and videos directly from my smartphone.

My FC (https://www.banggood.com/Upgrade-NAZE32-F3-Flight-Controller-Acro-6-DOF-Deluxe-10-DOF-for-Multirotor-Racing-p-1010232.html?rmmds=myorder&ID=17&cur_warehouse=CN) has no integrated OSD if I'm right (only connectors for it > 4 cables on UART1 > +,-,TX,RX). Or can I connect my camera directly to that OSD (grd,5V and TX or RX for video; no audio than??)?

Thanks for any help on this.

Small update:

Just put my mavic outside and ... YES: got a very quick 3D GPS fix!!

My motors seem to be lost somewhere on earth... Reseller sent them, the post got them, but I never didi. So an inquiry has to be started. First flytime will be without cam.

Now I need to buy some gold bullet connectors for my motors to connect (https://www.banggood.com/10X-2mm-Gold-Bullet-Banana-Connector-Plug-For-ESC-Battery-Motor-p-946666.html?rmmds=search&cur_warehouse=CN) and a Lipo charger. the one I bought is only to hook up on a car battery. Overlooked that...

Kananga, got the prop adapters sorted out? Don't hesitate to provide them.
How did you dismantle the original props from their connection?

I've not had time, work has held the printer mods up and I've decided to make a new enclosure while I'm at it.
They need tweaking in a few areas as I was still at the point of drawing then printing until I got the right sizes.
I had hoped to finish the printer today but I'll alter the drawing from memory and post the stl up, if you want to print one and try it I can alter any sizes and repost. Otherwise I can't test them until my printer is finished.

To get the pins out I pushed them from one side, I can't remember which side but the pins are stepped so push the smaller diameter side. The props then just slide out.

Thanks for the explanaition Kananga! I'll try it later today.

I'm really sorry but I've been super busy and only just got round to turning the laptop on to mod the files only to find when I did v2 I somehow did the alterations needed for the top part to the bottom part and visa versa so I can't actually use those drawings as they need a total redraw to get right which is the same as starting from scratch.
I have v1 files but they were wrong and I can't remember the alterations needed from v1 to v2.
Basically I know the mods needed for v3 from v2 but I don't have a useable v2.

I'm sorry to hold you up but now things have slowed down a bit I can finish the printer mods and will redraw the adaptors and do some test prints. I should have somthing this week.



I can't find any simular sized gimbal motors to the ones you ordered and I can only find those from the place you ordered from but after your experience I will not use that company so I'm stuck with the gimbal myself.

No worries. Still searching the bullet connectors. I'm sorry for your printer and the v2 files.

Regarding the motors, I thinks it is our post company that messed up, not the company where I bought them... I'll start the inquiry this week.

So ordered new one, together with a telemetry device (https://www.banggood.com/Flysky-FS-CVT01-Voltage-Collection-Module-For-iA6B-iA10-Receiver-p-976303.html?rmmds=myorder&cur_warehouse=CN) and some props just in case the adapters don't work out or PLA wouldn't work for them (https://www.banggood.com/GEMFAN-Carbon-Nylon-8045-CWCCW-Propeller-For-Quadcopters-1-Pair-p-950874.html?rmmds=myorder&cur_warehouse=CN)

As soon as I get the LEDs, I can try to fly  ;)

I'm really sorry I just don't have time at the moment and my printer is still in bits so I'm a bit stuck however I've just drawn them up again for you.
Try one of each and check motor fitment, prop fitment and pin fitment.
Let me know the changes and I'll repost modified ones until they're right.

First time I've ever shared printer files but hopefully they're ok.

Kananga, no hurry. I posted this so you would know there's no hurry. But thanks. I'll try this weekend to print them.

Kananga, it worked! I needed to print them on 105%, but then it worked. I'll print 3 others now at see if they all fit. One weird thing is that one of the two holes for the pins from the upper part seems a fraction larger than the other one. So there the pin is a little bit loose, but all the other wholes fit well. I don't have that issue with the bottom part. They also fit the motors perfectly.

That's great, the top holes are bigger than the bottom ones because the pins are stepped. If you want me to alter any sizes let me know.

Kananga, yes, that I saw, but I mean that one of the two holes in the top part piece is a fraction bigger than the other hole from the same part. But I'll test. Maybe 104% would be better, but I fear that it won't fit the shafts in that case. I'll keep you all posted.

Whats the big black box in your pics? Oh, it's your receiver, my bad.

indeed, the receiver. but I ordered a smaller one. the thing is that with this I should manage to get telemetry on my transmitter, on the small one not. but the mall one I could put in the nose of the mavic. So I'm still in doubt... Will see if I manage to get the telemetry or not...

Post by: foldingllama on March 13, 2019, 07:38:51 AM
Ok, those two holes were grouped together and dimensioned as one at 1.5mm radius.
I've split them to two dimensions making them both 1.5mm radius individually.
I can't see why it will make a difference but see if it solves it, the holes measure the same on screen so my only idea is that the group dimension is somehow confusing your slicer.
Let me know if it's worked, I haven't changed anything else.

thanks! I'll try.

OK, so GPS, sonar and LEDs working and configured! YES!


Next step was to check if I could connect the cam, but there I'm completely stuck...

The Foxeer Legend 2+ has 4 cables coming out (2 black, 1 yellow and 1 red) (https://www.banggood.com/Foxeer-Legend-2-F2_8-155-Degree-Wide-Angle-12MP-HD-WiFi-Camera-For-FPV-Racer-Drone-p-1053384.html?rmmds=myorder&ID=224&cur_warehouse=CN):
  • I suppose one ground (black)
  • one positive (red)
  • one video (yellow or black?)
  • and one audio (yellow or black?)

The FPV-transmitter (https://www.banggood.com/Eachine-VTX03-Super-Mini-5_8G-72CH-025mW50mw200mW-Switchable-FPV-Transmitter-p-1114206.html?rmmds=myorder&cur_warehouse=CN) has:
  • a pos & neg IN (towards my FC to get 5V I suppose?)
  • and a pos&neg&sign (yellow) OUT (towards the cam; just need to figure out which one on the cam is the video and which one the audio)


If I'm right I only need to connect those on the mavic and install the Go FPV-app of the FPV-receiver (https://www.banggood.com/Eachine-ROTG02-UVC-OTG-5_8G-150CH-Dual-Antenna-Audio-FPV-Receiver-for-Android-Tablet-Smartphone-p-1242422.html?rmmds=myorder&ID=224&cur_warehouse=CN). Is that right? But how do I connect the FPV-receiver to the FPV-transmitter? Only long pressing so it scans all frequencies?

No other connection to be made with the FC but the pos and neg of the FPV transmitter?

But I could also hook up via the foxeer-app directly and control the foxeer without all that if I'm not mistaken. That goes over Wifi. Just tried it, and it seems to work fine. Moreover, I can control when and where to take pictures and videos directly from my smartphone.

My FC (https://www.banggood.com/Upgrade-NAZE32-F3-Flight-Controller-Acro-6-DOF-Deluxe-10-DOF-for-Multirotor-Racing-p-1010232.html?rmmds=myorder&ID=17&cur_warehouse=CN) has no integrated OSD if I'm right (only connectors for it > 4 cables on UART1 > +,-,TX,RX). Or can I connect my camera directly to that OSD (grd,5V and TX or RX for video; no audio than??)?

Thanks for any help on this.

how did you wire the GPS? I bought the NZ one but can't set it up
thanks

Dear BerniApple,

On my FC (SP Racing F3 Deluxe) I just needed to wire UART2 like in attachment. Black to black, red to red, yellow from UART2 (3) to the orange from the GPS, and green from UART2 (4) to the blue wire from my GPS.

Inside my house, I don't get a fix, but in iNav I see it is working. When I put the drone outside, I quickly get a fix.

Hope this helps!

Wow Kananga, looks awesome. I follow your posts with foldingllama  :) while I collect parts for my build. Could you please share, how do you plan to place the antennas for receiver and FPV? In my build I plan to place it as in the original - in the front legs, now I am just trying customize legs to hold ESC and the antenna in the legs.

Folding Lama might help you better, mines stalled ATM while I build some foam planes lol.
There are some files on site somewhere that let you have escs in the arms.
I don't like running antennas with power lines so I'll not use the arms but I haven't looked where I'll route them elsewhere.

I agree, antennas with power wires are not very friendly  :) Moreover, it is already full of stories with clones of Mavik and their problems with compass and gps. I have on the side of the scale a compact and flush folding case, which is easy to take with you, and on the other hand the functionality of a drone with a camera and gps. I do not exclude that you can somehow bring the antennas outside, at least make them foldable. Have ideas to modify bottom base part. Anyway, I'll open diary and share experience ;)

I think something like Alexa's (http://diyrc.co.uk/mavic-build-diaries/mavic-f3-4-1-with-mods/), yet I don't think it would need to be that big...

But in meanwhile I can go testing by strapping the battery ;-)

Any Idea why?

Both aparatus get enough voltage. So that is OK. I connect my cam to the RX-cable of UART 1 (the FC should get the image from my cam), and I connect the TX-cable to the transmitter (the transmitter should receive the video and then transmit it to my phone). I want this setup so I can have an OSD on my phone (so image / video with supplementary information).

So, why ain't it working? In the manual of the SP Racing F3 Deluxe the UART 1 port / headers are meant for OSD...

Lama, from what I understand your correct, the advantage of plugging your camera through your fc at the moment is to configure/alter the settings of the camera through your transmitter.
You should however still get a picture I think.

To get osd you do need a separate osd board such as https://m.banggood.com/MICRO-MinimOSD-Minim-OSD-Mini-OSD-W-KV-Team-MOD-For-Naze32-Flight-Controller-p-990556.html?rmmds=search which can be run through your fc to add the additional osd.

Maybe you have to assign uart1 to be a video channel in inav or maybe toggle a switch, I'm sorry but I'm not sure why you're not getting a picture.

Kananga, no problem. I'll print an attachment part for my webcam and link it through the original Foxeer app. Will see if it works. Otherwise I'll do it over the vtx transmitter. As I can't have an OSD (for supplementary information on altitude, gps, battery status etc.), it doens't matter to get the image over wifi or the vtx. Just will need to see if the image quality is OK).

Are you serious?
I have just re-designed it from scratch and uploaded it on thingiverse. I though it was good and useful for the community. You can upload it on thingiverse and i will create a "remix".
Dont be mad at me.

How come it's exactally the same file as the one i uploaded here then.

I'm deadly serious, I believe you've taken my prop adaptor files I kindly drew out and uploaded to here and you've posted them on thingiverse under your name.

There are measurements on those adaptors that I made up and those measurements are on those designs.

calm down, I'm serious too. I can even share my solid works files if you want. of course its similar, i just copied your great idea. thats it

Still copied then, still my design, still no permission given, still no credit given.
Funny yours have same error mine did, same size angle mine did, same size flatter diameters mine did.
I'll let thingiverse decide, I'm never posting stls anywhere again.

As you said on pm it was my design you just copied and as you have offered via pm to remove from thingiverse that will be fine thank you.
You say you designed and drew it, at best you drew it but it's my design.

If it's removed it's matter over.

Hey, I have problems with my gps. I use the sp racing f3 and this nz gps:
https://www.ebay.de/itm/Super-Mini-NZ-GPS-with-LED-for-NAZE32-Flip32-6dof-10dof-best-for-QAV250-ZMR250/232287368499?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

I connected the wires like you and did the setup in inav like you, but gps is all time red in inav.
I changed RX and TX but same problem.
Any idea what can I do?
Thanks

I had the same when trying indoors. Is that what you do? In that case, go outside and try again. give it some time. Normally you should see in the GPS tab that the GPS is sending signals.

Hey @FoldingLlama.
Thanks for all of your info.
Just ordered screws and bolts from your links.
Avidly reading all of your electronics posts.... This will a big challenge for me.

Hey Folding.

Thanks for keeping the thread updated. Makes it a lot easier for us "noobs"... Anyways I am just about to start printing parts. I was wondering how far the document containing parts etc. is?

Also, do you have any suggestions for a flight controller which supports "automated" flight. I was thinking of getting a Pixhawk but it's a little expensive so I am looking at other options.

pixhawks are nice. Yuneec is also using those. But even with my SPRacing F3 and iNav on it, you can fly waypoints. I think other FCs also can do that. Here is a nice overview of different projects: https://blog.dronetrest.com/flight-controller-firmware/

Hey again Folding.

I've tried drawing/painting up a sketch showing the details of the wiring of this drone. As this is my first RC project I had a little difficulty finding out how to wire the different components. I was hoping you could answer some questions and clarify the wiring process.

How are the motors, StarF3S and FC connected to eachother? Did you supply power(battery) to the StarF3S and then 5V/GND to the SP F3?

Best regards.

Nice diagram and great that you are sharing it, @anonflem
I'm building the 4.1 Naza so not directly useful to me :-( however you've inspired me try to do something similar once I get mine wired (which will be some time since I'm still waiting for the flight controller to arrive).

hey @foldingLlama

How did you do the powerbetween the SP F3 and the StarF3S. Are you powering both boards individually or are you powering one trough the other?

best regards.

Well, the battery gets connected directly to the ESC. Between the battery and the FC I put a 5V BEC to power the FC. So not one through another, but parallel.

But in the scheme it shows, your ESC already has a 5V out? In that case, just connect that output to the POS & NEG of one of the 8 outputs on your FC and yo should be fine. My ESC didn't have a 5V output, so I needed an additional BEC.

Nice scheme by the way! (thanks @ BernieWoolf for the right link)

Hello, I have a question about the Accelerometer Calibration in iNav.

Do you do this when the flight controller is not installed and then completely flat like on a table. Or do you do the calibration in the installed state? When installed, the flight controller has a few degrees of slant because of the different leg lengths (front,back) of the drone.

Dear, To test it the first time I did it not mounted, but afterwards I did it mounted. Sometimes you'll need maybe to realign, so then it will be mounted. That's why I did my final calibration mounted. Good Luck!
