FS2004 tail draggers - no rudder pedals - what do I do??

Ok, I think the new planes in FS2004 are awesome, but as a person with
a CH yoke and no rudder pedals, how do I get them off the ground?? I
have auto-rudder enabled in my realism settings, I've tried
differential braking, all to no avail. I just can't seem to get these
things to turn while on the ground, and many of the "canned" flights
require ground steering to get to the runway. Am I missing something
other than the $100 of discretionary (aka money the wife doesn't know
about) income it would take to buy some rudder pedals?
