Electronics Hookup and Frame Reassembly


Assembled Quadcopter Top View.
Now that I have everything programmed up and have received all of the cables that I need, it's time to put things together.  There are just a couple of things you need to remember - red to red and black to black for the power board wiring.

Brown cables go to the outside on the control board and to the bottom on the receiver.  Aileron is Channel 1, Elevator is Channel 2, Throttle is Channel 3, and Rudder is Channel 4.




Assembled Quadcopter Side View.
This part is quick and easy.  For the ESC's the front left is motor #1, the back left is motor #2, the front right is motor #3, and the back right is motor #4.

Putting it all back together is a little tricky as you'll need more hands than you have.  I loosely screwed on each arm, and then used the second bolt to hold it all on.

What I did was the following:
Power Control Board is between the two plates on the frame and is held on upside down on the top plate by foam sticky tape.  The Receiver is held on by foam tape on top of the upper plate.  You then will put the control board on top of the whole thing.

Once you are done and everything is connected up it will look like this:
Now of course you can see that this leaves us with a problem that we have the control board exposed and the wires are just hanging out there.  I would like to add something above the frame to clean it all up, but more importantly to provide a little protection to the control board in case of an uncontrolled upside down landing (some of you might call it a crash).  I'm not sure what I'll do about this, but a trip to Home Depot is in order.

The frame is a tight fit for everything, and I'm already thinking about getting one that has a bit more room - over even better, building one from scratch so I can properly seat everything, screw it all down, etc.  However, that will be a ways in the future - first I'm going to get this one flying!

The battery mount is done by the velcro strap was provided with the frame - you'll need to run it through the frame and then use it to hold the battery in tight.  This seems a little unstable, but it also seems to be common practice.
