After this project http://birdman1goesoctocopter.blogspot.com/ I really got the taste of it, and guess what ?
Some parts of the blog will be copy/ paste from my octo blog, this to make it as complete as possible!
Let's start and unpack what we have till now!
Ok we got the 1.35 FC board, 4 Bl, 4 capacitors, and the ppm decoder+ usb connector and 10t cable
and ofcourse the navi and gps control unit.
Chapter 1: UNPACKING
brushless motors + cable set
and quadframe
Chapter 2: BASIC FRAME PREPARATION
Placing the rubber dampers, dont forget to use BLUE loctite
depending on which software u plan on using you can later on change the + DESIGN TO X
I will be flying in + style for now.
Dry fit FC to frame.looks perfect!
I plan on runnig the cables through the carbon rod , so first make sure that you break the corner from the carbon tube (on the inside--> grey part)
I
This is how we did it = takes 5 min to do the mod
STEP 1
STEP 2
STEP 3
Below you find the result, no special parts where needed to mount the brushless motors on the quad frame.
Chapter 4: PREPARING THE MOTOR's
My soldertips and tools
Let's start soldering, make sure that you have the right solderskills
and keep this in mind
My soldertools
Make sure that you have FLUX , use it at all placeswhere you need to solder ( the grease kind , not the liquid one)
To check each solder connection I use a magnifying glass with LED, so no shadow when checking a weld or tight spot, you can perfectly check each connection that you made!!
Ok, now we are ready to start soldering, you have different ways of soldering one cable to another
In this case i go for ultra strong connection, first bring flux/solder on both cables separate, them bring them aside from each other and reheat done!
Break the corner from carbon rod properly!!
DRY TEST
I came to conclusion after the dry test that there was little room for all cables to run through the connection, so to protect them i used a piece of 2 cm shrink tube NOW ATTENTION--> first twist as match as possibly the cables on the inside of the carbon tube, like that we reduce/avoid any future interference from those, now slide on the shirktube and push it 1 cm in to the tube ( so 1 cm out )
And heat ofcourse! the 1 cm the tube will not shrink , but it does what it is suppost to do , protect the cables!
Chapter 5: ADDRESSING THE BL
Address (Motor) | 1-2 | 2-3 |
1 (front) | open | open |
2 (back) | open | closed |
3 (right) | closed | open |
4 (left) | closed | closed |
chapter 6: PREPARING BL
Next thing , check which firmware is loaded on bl and check your addressing
OK, all perfect!
chapter 7 : BL INSTALLATION
solder the powerbus and SDA( BLUE cable + SCL(RED cable)
powercables +- 14 cm depending on which route you take
sda/scl cable +- 12 cm (twist cable to reduce interference!!!)
The Bl carry's not the best reputation , the amps that we can draw are very limited, so cooling down the mosfets as mutch as possible is the message --> that will protect our gear to the maximun!
I will place the Bl between the alu frame so that both sides touch frame and draw the heat away.
first we need some Alu
cut a stripe from +- 10 mm wide
cut in to 4 pcs from +- 18 mm
I use cooling paste between the little piece of Aluminium and bl + frame
first place a double sided sticker from +- 1.5 mm thick (DIY mirror tape)
now put some cooling paste on the mosfets
Position the mini alu plate
This is how I plan on cooling the bl as mutch as possible--slide your "BL-SANDWICH" between the frame and make sure that everything has a tight grip (dont forget cooling paste between alu/ mosfets /frame )
PERFECT FIT!!
Repeat proces with remaining 3 bl
Connect the MINI power distributionboard
First bring some solder on the complete board (be royal with it)
This is where I will place the POWER distribution
Connect the first power wire's, pay attention about correct polarity!
All done
connect the powercables for the FC
Connect the main C/D wire
and the small c/d cables from esc to distributionboard
Main power cable's
And then i placed a special isolating "carpet" below the distributionboard
Solder the main c/d connection to FC
PREPARING THE PPM CONVERTER
and buzzer
buzzer and ppm converter solderpoints on the FX
Now mount everything on your frame!
