Title: Mavic build - Mkc2
Post by: Mkc2 on May 27, 2018, 01:31:24 PM
Hi guys nice site.

Came across this site last week and thought I would give it a go.
Finished all the printing and just waiting on parts to arrive.

looks good, is the modification to hold the new larger type GPS unit.

I have the Naza N light and the GPS won't fit, I was thinking to place it in the same place you have.

any chance of posting the modified parts?

Regards
Neil

Iím going to remove the gps from its case and fit under the front nose cover.

Added the STL files, they may need cleaning up better.

Note: both covers are slightly higher to allow for more room, you will need to print
         them as a pair.

Just a question on the front legs where the motors are mounted, I have noticed that the motor tilts slightly back.
Is this correct or should they be level.

Hi,

I am interested in a few things as I am in the process of printing the parts to do my own build:

1) Where did you source the springs from please?
2) Have you successfully wired up the components?  I am new to the RC world so I have no knowledge of the wiring.
3) What screws are you using for the shell?

Thank you and it looks good so far :)

Plungers are from ebay, 6@ 6mm W x 7mm L.
I will be using the Naza light controller with gps, just waiting on the motors to arrive.
Socket head screws are from hobby king M3 25mm,26mm,30mm,35mm.

what size motors are you planning to use, I used 2212 900kVA which did not fit the arms designed for the Blackwidow ones.

I had to re do the end to mount the 2212 but had big problem making the changes, so the result is not good enough to share.
fusion 360 did not like to make changes to the files.

Opened up the GPS.
Glued the cable around and kept the notch to the front as thats the arrow forward, then put some hot glue in the 4 spots where the screws would go.
I put some tape over it to protect the components, the nose piece will hold it into place once bolted in, also I had to file a little section out so it doesn't touch the small components on the board.


Title: Re: Mavic build - Mkc2
Post by: Mkc2 on June 16, 2018, 02:49:23 PM
Next was to fit the Orange RX, I removed it from its case as that gives more room.
I then put some double sided tape under it and stuck it down.

Done for now, just waiting on the ESC then I can test fly it.
Its all binded to the Transmitter and the Naza software all setup ready to fly.
Title: Re: Mavic build - Mkc2
Post by: Mkc2 on June 17, 2018, 07:42:47 AM
Thought I would make some more room for the esc wires down each side of the controller.
I removed the 3 long tabs on the sides of the controller as you dont need them, the controller is recessed into the base and the battery base sits on top of the controller. Its not going any where.
Title: Re: Mavic build - Mkc2
Post by: Mkc2 on June 22, 2018, 03:11:30 AM
ESC arrived and they are tiny, it was a tight fit with no room.
I soldered one wire first and then tested the rotation before doing the other two wires.
Once the four arms were done I fitted them onto the body and checked there ok when folding.
Connected up the power wires and XT60 connector.
Powered it up and all motors spin in the correct direction.
Now waiting on props to fly it.
Title: Re: Mavic build - Mkc2
Post by: Mkc2 on June 22, 2018, 12:36:17 PM
Props arrived today, Yahoo !!
Well they weren't the right size with a 2.5mm hole and to thin for the prop adaptors, so I drilled them out to 3mm and fitted
a spacer under them.
Was waiting for bad vibrations but they seemed ok for now.

Wow.. super steady, you have to be impressed with it. Great build without a doubt :-)  Done in a short time too, well compared to my original one which was months and months.  Be interested in how the legs hold up to any heat generated by the esc's, but they fit well, nice find.

If the esc get hot and start to melt the legs, then I will make that area a little bigger with more breathing room.

Working on the gimbal, had to try different sizes until I got them balanced.
More to print tonight, the hard part is fitting all the boards, gimbal pcb,osd pcb and the 5.8ghz tx.

Printed a few different ways on how to fit the pcb and this was what I came up with.
Iím going to mount it with 2mm double sided tape, so will see how it goes for vibrations.

I tried to upload them but the site tells me they are to large at 1,100 KB even though it said 2,000 KB max.

PM me your email and I will send them.

After the test flight and all seems stable, I shorten the controller cables which freeís up a little space and weight.
Gimbal is mounted, stuck the Video TX underneath as this gets extremely hot and needs plenty of air.
Waiting on the gimbal controller and OSD to finish off.
Will test fly today as I can do video recording and transmitt back to my 5 inch screen.
Title: Re: Mavic build - Mkc2
Post by: Mkc2 on July 01, 2018, 12:50:37 PM
Well after todays flight and the mavic going crazy I decided to research and see what went wrong.
Found that the camera interference with the GPS causes it to lose control so you either have to switch to manual mode or crash.
After researching the internet, most camera's do this and it's a big problem with all the Naza GPS.
Tried adding some shielding but its not reliable.
So I removed all the camera gear and will just fly it as normal with GPS and return to home if I can no longer see it, Makes a great learner drone for some beginners.

Some flight videos to come when I get out again.

Hello MK2, is it necessary to leave the gps naza of the frame?
Patrick
Title: Re: Mavic build - Mkc2
Post by: Mkc2 on July 02, 2018, 07:15:44 AM
I guess you could but you wont have return to home if you lost signal.
More manual flying and altitude mode.
Title: Re: Mavic build - Mkc2
Post by: patrick57 on July 02, 2018, 07:55:07 AM
No, do not remove the gps but move.

Post by: Mkc2 on July 02, 2018, 01:21:46 PM
Thats why they have the riser post, to get it far as possible away from all your other electronics.
Would be good if there was a reliable fix.

Best place for it should be at the back, away from the camera gear.
Title: Re: Mavic build - Mkc2
Post by: patrick57 on July 02, 2018, 01:42:08 PM
Very good idea, I will look to change the frame to have the GPS at the back.
Title: Re: Mavic build - Mkc2
Post by: patrick57 on July 02, 2018, 02:32:35 PM
Can be like that

That looks cool, I hope it doesn't get any interference from the battery but its worth a try. 
Title: Re: Mavic build - Mkc2
Post by: jkaechler on July 02, 2018, 09:21:39 PM
I have not tested this yet, but i have my GPS puck mounted on top of the nose lid, and the bottom of the nose lid is covered in two layers of copper tape.  In the second pic you can see the edge of the copper layer that covers the whole bottom of the forward lid area.

The goal is that the copper barrier will reduce the EM interference from the various electronics to the GPS antenna.

I realize i dont know how to post a pic on this forum.  I hope an imgur link is ok.

Well with not being to happy with the prop adaptors not fitting the folding props, I ordered some fixed props.
After watching a video on flight time with fixed, folding pair and folding triple props, the flight time was 13,10 and 8.
So I found 2 different set that fit from hobbyking.
One with 8mm shaft with the square sides, fit perfect.
The other are self tightning props that were a little tight and just needed a 8mm drill bit to ream out a fraction.
Doing a test flight to see how they go, night time here :)

Edit: just did a quick test and the props were very smooth and a lot quieter, very happy.
Title: Re: Mavic build - Mkc2
Post by: Mkc2 on July 06, 2018, 02:53:09 PM
Did a few more flight test. 15 minutes of hovering and the esc were still cold, happy about that :)
Played around with gains to get it alot more steady.
Now to get out side tomorrow and do some return to home tests.

Just a short video on interference, This has copper tape under the gps and when close to a gopro in recording mode it loses gps signals.  Note: when not recording it was ok.

Title: Re: Mavic build - Mkc2

Well after mounting the GPS in the back and fitting the Runcam split back on, It still has interference and needs to be clear of about 10 inches away.
Even the copper tape seems to make no difference.  >:(

Maybe more layers of copper would help?!

I think its the runcam, its to strong with interference and worse then the gopro.
I will give the Mobius camera and try.

Post by: Mkc2 on July 10, 2018, 01:51:56 PM
Well I tried 3 cameras and no luck with the interference.
I gave up and will set up the camera and gimbal onto my tricopter which has plenty off room ( no gps )  :)
At least with out all that extra gear I can still have my 15 min flight time :)
Title: Re: Mavic build - Mkc2

Post by: skyman on July 10, 2018, 07:49:34 PM
try putting copper foil around the camera and a wire link to the battery -neg. screen the source and not the receiver. you want to ground the foil so the signal has some where to go.

Hello,

I solved a gimbal interference problem by using twisted wires to power the gimbal motors, this is a simple solution that might work.
Of course I assume you did a mag calibration of the Naza after installing the gimbal.

MKc2,the interference comes from the camera "runcam split" and no "storm 32". If we change the cmera for gopro there will be more problem!
 ??? ???
Title: Re: Mavic build - Mkc2
Post by: Mkc2 on August 03, 2018, 10:09:05 AM
The runcam split and the gopro seemed to interfere with the naza gps and worse when in recording mode, maybe others using different setups with a different branded gps maybe ok. We dont here from anyone with working gimbals to see what they get.

Nice video but his camera is a lot further away then the mavic. The shielding helps and may stop it depending on how thick you wrap it.

Just did a quick test and wrapped the gopro in aluminum foil, every layer gets you closer and it took 8 layers to get the gopro under the mavic. Not going to use a gopro, its only for testing.
Title: Re: Mavic build - Mkc2
Post by: patrick57 on August 03, 2018, 05:19:07 PM
I understood that it was necessary to move the GPS away from the camera.
I decided to redo an enlarged Mavic.
