Firstly, I want to say thanks to APM2.5 dev team, 3DRobotic, their open source projects that helped me a lot to complete my first drone, include xtPilot - a modified hardware shown above, original is APM2.5 open hardware project.
(see my previous post - low cost version of APM2.5)
I have bought F450 frame (a clone of DJI450 frome china with very cheap price - $18.4 :D ) but I don't have the flight control board and brushless motor yet. I have just received 4 MT2216-900KV t-motors with nice price from a friend as the same time when I finished my flight control board.
bad quality APC 10x4.7 propeller T.T (I can't find where to buy a genius APC or better propeller, because the ship fee from EU, US and other countries to my hometown is too expensive T.T - I was so happy with 4 original t-motor as least :D)
Motors were mounted to frame:
Now is the main parts to build my first quad ^^
I/ Mount the Hobbywing Skywalker 20x4 ESC
I've tried to use bandage to keep that ESC but...it's so ugly, so I use another way to mount it to frame and...hola..it's ok ^^
Firstly, I drill a small hole with size is equal to the screw I have on the top fiberglass of frame
The result is 4 holes:
Then open the ESC:
Closer look on Quadtro 20x4 ESC:
Maybe they used a good swiching power supply for 5V output, I hate 5V output by 7805 >.< it's so easy to die someday and can burn out your flight control.
Secondly, you need to drill 4 holes on the back cover of ESC like the picture (it must be same with 4 holes you drilled on the top fiberglass of frame above):
Use this screw to mount on the top fiberglass:
Combine two things above we will get:
Attention: you need to ensure that the top of mounted screws on the back cover of ESC don't touch will any components of ESC when you close the cover to the board. Do with your own risk
Finally, we will get:
Better than ever :))
By completing the frame setup and...
II/ Vibration Damping for xtPilot
Now I show you how to make a simple vibration damping but it can reduce the vibration to between -1 and 1
Firstly, you cut a small copter board, just about 8x8 cm and drill 4 holes (depend on your flight control dimension, here is xtPilot, 5.6x5.6cm)
and the hole's information like the picture with the center is the edge of flight control board , diameter is about 5mm (depend on your damping ball) .Sorry, I forgot to take the picture :D
Mount the damping ball between the holder board and xtPilot:
and we get:
And here is the result I tested:
Closer look on AccX and AccY
III/ Finish the Quadcopter with xtPilot
Wire the motor signal:
Mount the receiver Flysky th9x
Finally, mount xtPilot fly control and complete signal connection:
Just connect to Laptop and setup new system
JUST ANOTHER STEP IS....TUNING PID AND...TRY TO FLY MY FIRST QUADCOPTER....WAWWWW.... ^^
Have a nice day! From Vietnam with Love!
