I am completely new to the world of hobby UAVs so apologies if this question sounds a bit trivial, but any help on the matter would be greatly appreciated.
I recently purchased a new ardupilot mega and oilpan. After soldering and downloading the software I am keen to connect my RC gear and get going, but am terrified of doing it wrong!
Firstly should I connect my receiver to the input channels on the Mega Board, and then connect my servos to the output channels.
However, if I then put attatch my battery and motor to the ESC, and connect that to the output channel of the Mega Board, will that operate correctly?
Again, apologise for the probably trivial question, if you need any additional information please comment.
I'm also a beginner. For the initial phase, I want to use the board only as a datalogger which will get the sensors and GPS readings of several manually flown air vehicles. Please correct me if anything is wrong with what I think: Board must have its separate battery. Also I don't need servo power so I will leave the jumper off. In order to power up sensors processor and sdcard which pin should I connect the 5V supply? Thanks.
If you leave your jumper off, the only way you could power your board would be by the input rail.
The + pin in all RC 3-wires wires used to be the center one, to avoid polarity change when hooking it in the wrong way (+ allways stay in center of the 3 pins). Here you can see the polarity of your input rail:
You can use any of the inputs and anything but the output rail will be powered.
I'm having a bit of a different issue and could use some clarification on how to power everything.
In my case I am use a large servo that requires 6v or 7v and my Castle Creations Phoenix Ice 50 BEC is programmed to output 6v accordingly.
So I need 6v to my servo. I don't really want second battery right now. Can somebody diagram for me how I might set this all up for use with the APM 2.0 + telemetry.
I would think a second BEC, set to 5V, just to feed the APM and telemetry, RX, radios etc. That way you keep servos separate (on the existing 6-7V BEC)
I have 2 BECs and a switch on each, so that I can turn things on in stages.
Could you diagram that for me? I'm having a hard time seeing how everything would be connected.
Ordered a castle creations BEC. I have a rudimentary plan now. I will post a diagram when i am finished so it can be double checked.
I'm not sure what the problem is. Perhaps you have a bad board. Mine powers up just fine from either the input or output.
Yes, I agree.
It would be extremely helpful for an "expert" to show some general and specific wiring diagrams with photo's showing the various possibilities of powering the APM2.
Some notes and/or warnings with a few of the key "what not to do" for the most common mistakes would also be very helpful.
Forgive me if one has allready done the above, sometimes I get lost in DIYDrones trying to find specific answers to these questions. Please point me in the right direction if we have allready explained this in great detail.
At $200 a pop (pun intended :) , I'd rather spend those dollars buying more fun things from DIYDrones.

Just read the message I just posted will make some linght on the powering AMP and others.
I think a little drawing and maybe some photo's would help a bunch :)
A few people requested a diagram to explain the power options. Based on DahaS's post I created this...
JP1 connects the input and output power rails.
Connecting +5V from a power rail to the USB will fry it.
So basically you must not have ESC/BEC power running to the Input rail, either directly or via JP1, while you have the USB connected.
