match box
You do not have to run matchboxes, but they certainly help. I've set up planes with 2 channels, Y'ing to each servo in each wing, using 4 channels mixed together, and using the matchbox. I would say the matchbox is the best option of the 3. I still use 2 channels, but use the matchbox instead of the Y harness. This way you can still use the ailerons as flaps. You can make finer adjustments with the matchbox than having each servo plugged in individually. This allows you to reduce the current draw much easier, and better.
