Tracy:

Most people never use the rudder in the air and never use the ailerons on the ground. Since you probably hope to spend more time in the air than on the ground, you will want ailerons more than rudder.

If you have an extra servo, you can Y connect it to the nosewheel for ground steering. Or fix it in place and hand launch.

Why not hook up the rudder and nosewheel in the conventional manner and Y connect them both to the ailerons.

Try lots of things, you're just experimenting anyway. Nothing you do with 3 channels will make it fun to fly.
