I've never had anything to do with a Chippie but of the various tailwheel machines I've flown I agree with 747 that the Maule was 'interesting'.
I seem to recall they've a fairly short wheelbase so rather quick in terms of any directional movements (intended or otherwise!) on the ground.
That said I strongly concur with those that have suggested using something a little more docile, at least for your initial training. Unless you're used to driving a forklift at 100km/h across rough ground you're not going to really enjoy the machine much until you've got an hour or so under your belt...
