Well, with a fancy dx6 radio, I guarantee everything that you have should work together if set up right. Your radio probably has different programs built into it for different kinds of models, like standard airplane, V-tail, helicopter, and CCPM helicopter. Make sure the right program is selected on your tx first. I would assume that the instructions would tell you what each channel is designated for. But who really needs instructions? Just pick one servo, and start plugging it into one jack after another on the rx. By process of elimination, and moving around the sticks, you'll figure out what servo wire should go where. The right stick should control servos that are responsible for tilting the swash plate. With the motor unplugged from the ESC, move the throttle stick up, and another servo should move to increase pitch. To get the gyro and tail servo to work, two more channels are needed. First, just plug the tail servo into various ports and move the left stick from left to right, until the tail servo begins to respond. You've found the channel that controls steering. There will be another channel in your system that is used to control the mode that the gyro is in (head lock or rate mode). I would assume that it is channel five, but figure out where all the proper ports are for the other servo wires first. The gyro itself will have two input wires coming out of it, and an output wire. One of those input wires will plug into the channel that you used to move the tail servo. The other input wire will plug into the channel that is used to switch the gyro's mode. The output wire will then go to the tail servo itself, so in this manner the gyro is between the channel that controls steering and the tail servo that executes the command.

So, after you've gotten all that wired up, the first thing is to test things out. Put the heli in the middle of a large, smooth floor, and slowly throttle it up, just fast enough so the tail rotor has enough speed to make it want to turn one way or another as it sits on the floor. Does the nose of the heli move in the direction that you point with the left stick? If so, then good. If not, flip the forward/rev switch for that channel on the control or whatever setting is used to reverse the servo direction on your tx. Then, notice what happens as you move the stick right or left. Does it stay locked, or does it just spin around wildly? That means that the direction of the gyro needs to be reversed (so that when it senses movement one direction, it compensates oppositely). Usually, the gyro itself has a forward/rev switch on it, but some of the fancier ones are controlled by the TX.

There ya go.
