A chipmunk would be a handful as a second plane. Good choices for a secong plane would be (in no particular order):

Hangar 9 Pulse
Hangar 9 Saratoga
Goldberg Tiger
Hangar 9 Twist
Sig 4-star
The Wold Models Paulistinha

The Chipmunk could be used as a second plane if you had access to an instructor and a buddy box. If not using the instructor and buddy box, you're better off with one of the above planes.

Good luck!

Oh yeah, how could I forget about the Great Planes Big Sticks- they're great too!
