Hi!
I just purchased a 3DR quadcopter kit, and I've been able to put together the frame and most of the electronics. I have some questions regarding the connections between the ArduPilot 2.5 and my receiver.
I've attached two pictures to better explain my questions. One picture shows the cable that connects to the APM 2.5 input (for clarity, each cable is labeled). Note that the ends of each of these cables (A through H) have a 1-pin connector. The next picture shows my radio receiver that I will be using. Here are my questions:
a. can I connect the 1-pin connectors from the APM 2.5 to the radio receiver?
b. if so, which cable goes to which channel?
c. which cable goes to which pin position (see picture for labels at each possible pin position)? I've included a connected servo just for your reference.
Thank you SO much! Any advice would be super helpful!!

The outer pins on your radio are the ground pins, the middle pins are the power (5v) pins, the inner pins are signal pins.
The yellow wire on your servo is your signal pin for that servo. Red is power on your servo and black is ground.
You need to connect at least 1 power and 1 ground to APM from your radio. The others go to signal pins. On the APM you'll see 1-8 labeled on the input. Line up those numbers. You'll need at least 5 wires (ch 1-5) to get basic functionality. Hook up ch6 for tunning and camera control, ch7 for extra features such as recoding waypoints.

Lucs,
I'm the team lead for the Documentation User Group (DUG) & I'm working on a wiki page that addresses your questions for APM 2.5. Until I get that posted, see if studying this link doesn't answer your questions.

white/gold wires are usually signal wires so they connect to APM.
