Mavic build - paubica7
« on: January 09, 2018, 09:39:55 PM »
Hello guys,
I have been watching your diaries some months ago; finally I decided to build my own. I took different ideas from another builder and got the best things from every diary.

I start my first printing with grey and some black pieces in PLA. I use to program impression the Simplify 3D. The process for impression is the next:
•   70% infill all pieces – If I will have some weight problems I will reduce infill the some pieces.
•   205şC
•   2400 mm/min
•   1.8 mm layer

And this is the result at the moment.





This pieces are a modify from one guy from this forum that I don’t remember his name :(, but it’s perfect, more space it will be perfect for assembly.

The arms are from SICARIUS, I love it’s possible to put inside the ESC. 

I printed some noses and different gimbals parts. But at the moment I only want assembly Mavic without gimbal and do some fly tests. Finally I will decide to continue with gimbal project.

And this is the “assembly mavic” I like it.  :D




As soon as possible I will post my BOM.
I am still waiting to receive all components that I bought in china. I think they're coming with a rowing boat ... ??? ???

I know the feeling well. Right after I gave up on some of them and ordered elsewhere, the original parts finally arrived.

Hello,
@iRazoR, thanks! I will print extended legs in black too.
@KDan, haha in my case the shipment to Spain normally is the three weeks, but in my last order more than one month! I hope will receive it during this week.

Now I will post my bill of materials:

FC
I decided to use for a flight controller Naza m lite because I have experienced with it in my another quad F450 and I know how it runs and I like it, easy setup, gimbal control, Fail safe, and more options. And I decided to choose M8N GPS for to remove the cover; one nose part runs in this forum for this GPS type.

Engines

I use the same as in my other F450 less spare parts

For transmitter and receiver I will use one old that I had. For principal flying tests, but I love this type of transmitter, but I don’t know if it will be run with naza m lite.. Anyone know it?

you can get 10 channels out of your i6 by flashing it with FS-i6x firmware and getting a A8S receiver and hooking it up with i-BUS.

I would go for 1400kv motors since the real mavic has 1400kv motors. i'm pretty sure dji has done their homework to determine for this prop size, weight class and 3S battery that is the motor to use.

For the props i would go with the mavic pro platinum style ones with the winglets on the end. it reduces turbulence at the tips making it more efficient and quieter.

Do you know of a 1400kv motor that will accept the original Mavic style 8330/8331 props with the quick disconnect?
(Other than the original DJI replacement arm/motor assy that are about $40 USD each)

since he was going to go for the XXD motors he can just buy them in 1400kv.. they are available...
be aware tho, those XXD motors are the lowest of the low in quality now days. back in 2012 when i first started building i had a set of 1100kv that flew so smooth and beautifully, so in 2015 i got a set of 1400kv they were total crap with noisy and loose bearings.

there's also the emax xa2212 and dys d2826 both has a 3mm shaft and available in 1400kv

edit: i think i misread your message there. i was just thinking in terms of what the OP could have used instead. No i don't know of any that will accept original DJI quick release props. but i thought i saw a 3d printable adapter to make it work somewhere.

Mm.. I don’t have any experience with this model.. Is too new!! First orders will send 18th January, we can wait some post or reviews
In banggood appear this.. but maybe it’s possible to flash it.
Q: 12 buttons and only 8 channels :-/
A:
Hello, yes it is only 8 channels.
Answered by Lanny on November 30,2017

Why you want 10 channels or more?  With 8 channels you should have:
1.   Pitch
2.   Roll
3.   Yaw
4.   Throttle
5.   U (swich 3 positions – GPS – Atti. – manual
6.   F1 (gimbal Roll) – for me this isn’t necessary. I have configured F/S – Go home and landind
7.   F2 (gimbal Pitch)

Tell me.
I have this TX: Flysky FS-i6X 10CH 2.4GHz AFHDS 2A Transmisor de RC con Receptor FS-iA10B, for my F450.

I didn’t buy this motors I have it from another quad. At the moment I want to assembly and fly. Then I will decide if upgrade quality of components or not.
Thanks for your help and comments I will put this motors in my wish list from banggood maybe I will buy.

I hope to receive this week the components that I need to start assembling it in the weekend

The more Channels the better :)
I would also like to be able to control the Runcam Board which need at least 2 more Channels but is not reall necessary.
I will definetly look further for a nice and handy Remote Control after I did some flight tests with the current setup

I ended up with two different motor setups after waiting forever for the first one to arrive. I wanted a setup with quick detach props. The second set of motors I ordered were these from RTFQ's. Someone else in the forums - @Rickyg32 - had also bought these motors and was looking to have an adapter printed in order to use the DJI Mavic style quick detach props. I've been messaging with him and we are taking two different approaches to create a suitable adapter. The first was to use a quick release base mount and then print an adapter to fit the screw pattern on the motor.
The second approach was a fully printed single piece prop adapter that I designed yesterday. I think it should work. There is a LH and RH version that takes advantage of the direction of rotation to keep the prop firmly secured. Attached is a picture and rendering.

The props attach quite securely and there are RL and LH versions to use with the corresponding props. This helps ensure they will stay in place. They seem to run straight and true. I'm working on a lot of other modifications right now and it will be several weeks before I am ready to do any powered tests. Once I starting putting things together I plan to start a build thread. I think all of the parts I need have arrived.
